HVAC, or heating, ventilating, and air conditioning, is a term that deals with the climate control of a structure. In some regions of the world, HVAC will also be used to refer to electrical issues and plumbing. The heat, ventilation, and air conditioning of a structure are all interconnected. The goal of HVAC is to provide an architectural structure with a high quality of indoor air, as well as excellent thermal properties and competitive installation costs. A system that is built with HVAC properties can also reduce the amount of infiltration that is present in a structure. In most modern buildings, either one or multiple HVAC systems will be used. If the building is fairly small, the construction company will generally select specific HVAC systems that can be efficiently used with it.

Fort Lauderdale, FL - DtiCorp.com (http://DtiCorp.com/) is introducing today a brand new HVAC Database with 58,851 total records. You can download a sample spreadsheet here:

http://dticorp.com/catalog/data/HVAC_Contractors_Sample.xls

HVAC is an initialism or acronym that stands for "heating, ventilating, and air conditioning". HVAC is sometimes referred to as climate control and is particularly important in the design of medium to large industrial and office buildings such as skyscrapers and in marine environments such as aquariums, where humidity and temperature must all be closely regulated whilst maintaining safe and healthy conditions within. In certain regions (e.g., UK) the term "Building Services" is also used, but may also include plumbing and electrical systems. Refrigeration is sometimes added to the field's abbreviation as HVAC&R or HVACR, or ventilating is dropped as HACR (such as the designation of HACR-rated circuit breakers).

Heating, ventilating, and air conditioning is based on the principles of thermodynamics, fluid mechanics, and heat transfer.

The three functions of HVAC (heating, ventilating, and air-conditioning) are closely interrelated. All seek to provide thermal comfort, acceptable indoor air quality, and reasonable installation, operation, and maintenance costs. HVAC systems can provide ventilation, reduce air infiltration, and maintain pressure
relationships between spaces. How air is delivered to, and removed from spaces is known as room air distribution.

In modern buildings the design, installation, and control systems of these functions are integrated into one or more HVAC systems. For very small buildings, contractors normally "size" and select HVAC systems and equipment. For larger buildings where required by law, "building services" designers and engineers, such as mechanical, architectural, or building services engineers analyze, design, and specify the HVAC systems, and specialty mechanical contractors build and commission them. In all buildings, building permits and code-compliance inspections of the installations are the norm.

The HVAC industry is a worldwide enterprise, with career opportunities including operation and maintenance, system design and construction, equipment manufacturing and sales, and in education and research. The HVAC industry had been historically regulated by the manufacturers of HVAC equipment, but Regulating and Standards organizations such as ASHRAE, SMACNA, ACCA, Uniform Mechanical Code, International Mechanical Code, and AMCA have been established to support the industry and encourage high standards and achievement.

Fort Lauderdale, FL - The Honeywell IRIS CS550/552/556 viewing head/flame detector detects the presence or absence of flame, features a digital display, quick disconnect plug, gain setting, selectable flame on and flame off settings for added flame discrimination and NEMA 4X / IP67 enclosure rating. Viewing head has CSA rating for Class 1, Div 2, Groups A-B-C-D, T5 hazardous environment rating. Perfect for difficult sighting and multiple burner applications.

Honeywell IRIS S550B GENERAL DESCRIPTION

The IRIS Model S550B is a state-of-the-art flame monitoring viewing head utilizing two types of detectors: an IR (infrared) solid state sensor and a UV (ultraviolet) photo sensor.

The S550B works with the latest version of the P520, P522, P531 and P532 signal processors. Like other viewing heads in the S5xx family of viewing heads, the S550B produces output pulse rates proportional to the flame signal strength; the pulse rates are displayed at the front panel of the signal processors. Unlike the other members of the S5xx family of viewing heads, certain parameters in the S550B viewing head can be selected or adjusted remotely from the front panel of the P520, P522 and P532 signal processors. These parameters are:

a) UV gain 0-99

b) IR gain 0-699

c) Filter Selection 1-8

Once adjusted, the new parameters are stored in EEPROM in the signal processor. If power is removed from the signal processor(which powers the viewing head) and reapplied,the signal processor then automatically resends the stored parameters out to the S550B viewing head. In addition, at the front panel of the signal processor the operator may also select "CAL", a semiautomatic mode which will help to speed up the S550B setup. Thus, the S550B is a dual-sensor viewing head where the gain and filter selections are adjusted and stored remotely by the P520, P522, P531 and P532 signal processors.

The IRIS Model S550B Viewing Head has FM (Factory Mutual) approval, and CSA (Canadian StandardsAssociation) Certification to US Standards (ANSI/UL) for Class I, Div 2, Groups A, B, C and D for Hazardous Location Applications, T5 Operating Temperature Ambient -40C to +70C, Enclosure type 4X.

Honeywell IRIS S552B GENERAL DESCRIPTION

The S552B is for IR sensing only. It is basically an S550B without UV capability. The P520, P522, P531 or P532 will be aware of which viewing head of the S55xB family is connected to it so that only those adjustments which are appropriate to the S552B will be made available tothe operator. These adjustments apply to the S552B:

a) Filter Selection 1-8
b) IR gain 0-699

When it comes to features like "CAL", the operator is given only those choices which are appropriate. For example, the operator does not have to choose between calibrating with the UV sensor or the IR sensor; in "CAL" but is only offered the choice of calibrating with the IR sensor.

Honeywell IRIS S556B GENERAL DESCRIPTION

The S556B is for UV sensing only. It is basically an S550B without IR capability. The P52x or P53x will be aware of which viewing head of the S55xB family is connected to it so that only the adjustment which is appropriate to the S556B will be made available to the operator:

a) UV gain 0-99

When it comes to features like "CAL" ,the operator is only given those choices which are appropriate. For example, the operator does not have to choose between calibrating with the UV sensor or the IR sensor; in "CAL" but is only offered the choice of calibrating with the UV sensor or not.

The IRIS Model S552B Viewing Head has FM (Factory Mutual) approval, and CSA (Canadian Standards Association) Certification to US Standards (ANSI/UL) for Class I, Div 2, Groups A, B, C and D for Hazardous Location Applications, T5 Operating Temperature Ambient -40C to +70C, Enclosure type 4X.

COMPARISON WITH OTHER MODEL S5xx SERIES VIEWING HEADS

The S55Xb uses a Germanium sensor for IR detection, like the S511 and uses a UV TRON® Photo Sensor for UVdetection, like the S506, but both sensors are in the same housing in the S55xB. The pulses from the UV and IR sensors are summed internally into a single pulse stream out to the signal processor.Adual-LED digital display is used to indicate the first two digits of the signal processor, which indicates the pulse rate out of the S550B. It is visible at the rear of the viewing head housing. The UV sensor emits green digits and the IR sensor emits red digits. With a count rate of 1200 displayed at the signal processor the LED will display 12. This is very useful for aiming and sighting the viewing head. One can readily distinguish the differences by reading the LED and use this indicator to adjust the sighting to obtain a maximum pulse rate at the LED, and therefore a maximum reading at the signal processor.

Another difference from previous models is that the gain for each sensor and the selection of the filter for IR may be set remotely through the front panel of the P52x/P53x signal processors.

Another difference from the earlier S5xx family of viewing heads and the S55xB family is that the earlier viewing head family had only 4 high pass filters to choose from; the S55xB has 8.

HVAC Solutions from McDonnell & Miller:

* Boiler Controls.

STEAM BOILERS - Steam Heating Boilers are classified as boilers in closed heating systems where all condensate is returned to the boiler. Best recommendation for all automatically fired boilers is a feeder cut-off combination. It adds water as needed to maintain a safe operating level, and stands by to interrupt circuit to burner if water level drops into emergency zone. Steam Process Boilers are classified as boilers in systems where not all the condensate is returned, and some make-up water is needed. A separate feeder and separate cut-off are recommended, so operating levels can be set for the wider differential required in such service.

HOT WATER BOILERS - Best recommendation for all automatically fired boilers is a feeder cut-off combination. It adds water if needed to match the discharge capacity of the relief valve, and stands by to interrupt circuit to burner if water level drops into emergency zone.

COMBINATION Low Water Cut-Off/Pump Controllers for Steam Boilers (42S, 93, 94, 150S, 157S, 193, 194).

Fort Lauderdale, FL - All customers will be able to enjoy the speed and convenience of payment with the American Express Card, and will also have the opportunity to earn a variety of types of rewards with every purchase from DtiCorp.com (http://www.DtiCorp.com).

Consumer spending on American Express credit cards is typically much higher than on other types of credit cards, while the costs associated with accepting AmEx credit cards through an American Express merchant account are low.

Since American Express cardholders have greater incomes, they tend to spend more. American Express cardholders are a high-earning group, with 45 percent of U.S. households that earn more than $50,000 annually carrying an AmEx card. Additionally, cardholders charge an average of 27 percent more with their American Express Card than their average spending on other credit cards.

With incentive programs like the Membership Rewards Program, cardholders are more likely to use their American Express credit card. More than half of cardholders enrolled in the Membership Rewards Program go out of their way to use the American Express Card.

American Express cardholders are a loyal group. According to Brookfield Research data from November 2008, 24 percent of American Express cardholders exclusively used AmEx in the past month and no other credit cards or charge cards.

But it's not only consumers who are ringing up charges on the American Express Card. Businesses have also gotten into the act, with 1.7 million companies using the American Express Corporate Card for their business expenses. That number includes nearly 70 percent of the Fortune 500 -- the list of the biggest corporations in the U.S.

"The timing is perfect," said John Marino, vice president of marketing for DtiCorp.com. "Our ability to accept American Express Cards will bring added convenience to our customers and incremental sales to our company."

Metering the refrigerant flow to the evaporator is the sole function of a thermal expansion valve (TEV). What's critical is that it must meter that flow at the same rate it is being vaporized by the heat load.

To do this, it keeps the coil supplied with the proper amount of refrigerant to maintain the right superheat of the suction gas leaving the evaporator.

TEV operation

o At point A, hot, high-pressure liquid refrigerant enters the TEV.
o At B, cold, low-pressure liquid plus flash gas enter the evaporator.
o At C, the entire liquid refrigerant has been boiled off or vaporized by the heat load (latent heat).
o Between C and D, the vapor temperature increases dramatically as further heat load is applied (sensible heat). At this point, the gas is superheated above its saturation temperature.
o At D, the suction line temperature of the superheated gas is monitored by the sensing bulb, which signals the TEV to open or close accordingly.

Because good superheat control is the criterion of TEV performance, accurate measurement is vital.

How to measure superheat accurately
Measuring superheat involves four steps.

Step A: Determine the suction pressure at the evaporator outlet with an accurate gauge. If there is no gauge connection, a tee installed in the valve's external equalizer line can be used.

Step B: Refer to a temperature-pressure chart for the refrigerant used in the system, and determine the saturation temperature at the observed suction pressure.

Step C: Measure the temperature of the suction line at the remote sensing bulb location. This can be accomplished by a strap-on thermometer or an electric device similar to an "Annie" or "Simpson" meter.

Be certain the spot chosen for measurement is clean to help ensure accurate readings.

Step D: Subtract the saturation temperature determined in Step B from the suction gas temperature measured in Step C. The difference is the operating superheat.

Which valve to use
Some service technicians seem rather uncertain as to when to use an internally equalized thermostatic expansion valve and when to use an externally equalized one.

Our experience has shown that an externally equalized valve should be used whenever pressure drop through the evaporator reaches:

o 3 psi in a 3-ton (or 3-hp) air conditioning system (evaporator temperature range of 30° to 50°F);
o 2 psi in a 2-ton commercial refrigeration system (evaporator temperature of 10° to 30°); or
o 1 psi in a 1-ton low-temperature system (evaporator temperature of 0° or below).

On this basis, an externally equalized valve would automatically be the selection for any system in excess of 3 tons, regardless of the application.

Where to place the bulb
Good temperature feedback to the TEV is vital for control. Place the bulb where it will provide the best possible feedback.

Never put the bulb at 6 o'clock because it may sense the temperature of the oil flowing through the pipe, rather than the temperature of the refrigerant.

Finally, be sure the bulb location is on a free-draining suction line.

Choosing the proper TEV for the specific system remains the first step in good service - and no callbacks.

The HVAC system uses three closely related functions, namely, heating, ventilation, and air-conditioning. These functions are uniquely set up so that they can regulate temperature and humidity in residential homes, public offices, and other building facilities with respect to the overall design of the structures.

The heating system can either be central or local. The most commonly used setup is the central heating system where the heating is concentrated in one area-central-and is then circulated for various heating processes and applications. Heat values of fuels are based on BTU to cubic foot measurement for HVAC.

In the central heating system, there are three common components used. A furnace is an enclosure used for heating and can be found at the basement or at the attic. Different cultures have various interpretations of "furnace." For the Americans, it is similar to kiln while for the British, it is equivalent to industrial furnaces. Whatever it may be, it still uses the same principle for heat distribution-that is, it transfers heat using an intermediary distribution system. A boiler, meanwhile, is a type of furnace-in fact, a closed vessel-that distributes heat through steam.

Thermodynamic principles are the bases for a heat pump. This device causes the temperature to rise through heat transfer. A heat pump is very effective especially for very cold air since it has the ability to heat it at the shortest period. An efficient heat pump uses lesser energy and thus power.

A radiator is a heating device that circulates steam or hot water through pipes found inside an upright metal structure. This term is also commonly applied to some types of heat exchangers. It is a common perception among people that heat is transferred from a heat exchanger through radiation when, in fact, it is not. It transfers heat by convection, which uses currents.

Please note, though, that the central heating system is completely different from your hot water supply. For instance, the water used in the former is not the same as your tap water.

Ways of Central Heating
There are a number of methods for central heating. In electric heating, an electrical heater is used. It is a device that transforms electrical energy into heat. Every electric heater contains an electric resistor, which acts as its heating element. Right now, there are many variations of electrical heaters that deliver different amounts of heat, but all of them use the same principle: Joule heating. An electric current that converts electricity to heat is allowed to pass through the resistor. In hydronic heating, heat produced is commonly transferred to fins found along pipes in baseboard HVAC registers. You can also use coal, propane or natural gas, pressurized oil, or earth, which is used as a heat pump.

Air-conditioning
Over the years, air-conditioning has changed home lifestyle. A lot of London homes right now take advantage of wall-mounted air-conditioning systems. They are often placed in the living room, bedroom, kitchen-in almost all over the house. Most buildings and offices also have hidden condensing units. Cooled places become refuge to those who are tired with the rising temperature outside.

There are various air-conditioning systems in the market, but they all function just the same. They control temperature, ventilation, and humidity in an enclosed environment. Hilsch air-conditioning uses a vortex tube called Ranque-Hilsch vortex tube for cheap spot cooling when you there is compressed air. However, it is not as efficient as usual air-conditioning equipment.

It is advisable that homes, buildings, and other offices have sealed windows to maintain the quality of air produced by the system. Furthermore, it is better to check the dwelling first to make sure that air conditioners can really be installed since they often use large ducts. But you really don't have to worry too much if it isn't. You can still take advantage of remote coils or use the split system. Yet it is always preferable to maintain the cleanliness of the ducts to prevent the growth of pathogens that can definitely cause illness. Sometimes chemical monitoring of HVAC systems is needed to always ensure indoor air quality.

Heating
Most modern structures in colder regions in the world and in countries with temperate climate such as the United Kingdom usually install a heating system. This mechanism is used to regulate temperature in residential homes, public offices, and other dwellings.

Your thermostat or programmable thermostat is an integral part of your comfort system. These thermostats, whichever type you have, require little maintenance. Sometimes the only thing people know about their AC and Heating systems is how to turn the thermostat on and off and change the temperature setting.

A very common occurrence with service calls is the complaint that the thermostat isn't working properly. Sometimes this is true but most often it is something entirely different. Because some people believe the only problem with the system rests with the thermostat, they'll go down to the local hardware store and purchase a brand new thermostat. They get home and dust off the tool box, never read any directions, and proceed to change the thermostat. Some are successful and some are not. Those that are most likely read some directions or had someone read the directions for them. The ones that are not successful end up calling a professional in to finish the job.

The bottom line advice to most people is to call a professional if something is wrong with your system. The problem may not be with the thermostat and you may exasperate the problem which will cost more in the long run. Additionally, If you have a multi-zone system, a high-efficiency heat pump or even just a heat pump, a regular split-system AC and a boiler for heat (and you have one thermostat), or an apollo based system (hot water heated in a water heater) with a split AC system, call a professional. These systems can be very complex and may require special sub-bases so the control circuit will work properly. Additionally, for heat pumps, there are different controls, and wires for these controls run into the thermostat, they are multi-colored wires. These controls can be very complex and each wire must go to the correct terminal on the thermostat or the unit will not run correctly.

Additionally, be aware that thermostats are equipped with heating and cooling anticipators. Cooling anticipators are not adjustable where heat anticipators are adjustable in mechanical thermostats. Setting the heat anticipator is important for your heating system to function properly. It is set according to the amp draw on the control heating circuit. Make sure the heat anticipator is set properly so you will get the best out of your heating system.

Installing a New Thermostat

The first thing you should do before changing the thermostat is to select the proper thermostat for your system. If you are retired or if someone is at home most of the time during the day you most likely do not need a programmable thermostat. If this is the case the only benefit you will get from a programmable is at night. Once you have made the selection you can proceed to the next step.

Thermostat Installation Advisory: If you decide to install your own thermostat you do so at your own risk. There are many incidences where the homeowner installed their own thermostat and were successful. There are also many incidences were the homeowner was unsuccessful. The ones that were unsuccessful wasted part of their day, ruined a thermostat or two, and caused the malfunction of an integral part of their system. That is not mentioning the fact that they ended up calling a professional HVAC Technician to fix the problems caused by improperly installing a thermostat. The ones that are unsuccessful end up paying three to four times what they would have paid had they called a professional in the first place. Factor this in to your decision and if there is any doubt call a professional to install the new thermostat.

* Get the tools together that you will need to do the job right. You will need:

o A small straight-slot (or flathead) screw driver
o A small phillips screw driver
o A pair of needle nose pliers
o A utility knife or wire strippers (for small wire)
o Plastic wall anchors (sometimes provided with the thermostat)
o A drill with a bit to make the holes for the plastic wall anchors
o A small level
o Two pencils or pens
o A small paper bag and some masking tape (tape the bag below the area where the thermostat is so that any trash or dust will fall into the bag and not onto the floor)
o Some touch up paint
o Clean hands (don't do a great job changing the thermostat and leave all those prints all over the wall)
o Plenty of light

* Turn the power off to the unit at the circuit breaker or the emergency cutoff switch. After doing that make sure the power is off by turning the thermostat to the on position and going to the unit to make sure it is not on. Not all circuit breakers are labeled correctly and not all emergency switches are hooked up. Just make double sure that you have killed power to the unit not only for your safety but also to keep from blowing the transformer.

* Pull the cover off the front of the thermostat. If it is a mechanical thermostat there should be a little adjuster tab in the center of it. This is your heat anticipator. It should have numbers ranging from 1.5 to .1. Take note of this setting and remember to set the new thermostat to this same setting if you are replacing a mechanical thermostat with another mechanical thermostat. You probably want to do this now before you proceed further. If you are replacing a mechanical with a digital, the digital should set itself automatically. If not read the instructions on the new thermostat for instructions on how to set the anticipator. This is very important. An improperly set anticipator will cause your heater to run improperly. The thermostat is also equipped with a cooling anticipator. Cooling anticipators are most often on the sub-base and are non-adjustable.

* Unscrew the thermostat from the sub-base. Take note of each wire. The following list should match the wires and terminals on your thermostat.

o Red to the RH or RC terminal with a jumper wire between RH and RC. Or Red to the R terminal which is shared with both the heating and cooling. It has an internal jumper built in to the sub-base. The red wire is the hot wire. All other wires are common wires.
o Green to the G terminal. This is for the fan.
o Yellow to the Y terminal. This is for air conditioning.
o White to the W terminal. This is for heating.
These are the four wires that you need to control the heat, cooling and the fan. If the colors of the wires do not match the colors described here make sure you mark the wires with masking tape. If there are more wires that are not hooked up don't worry. This is common. Thermostat wire comes in many different varieties and the contractor who installed the system probably used 5 wire or 8 wire thermostat wire. They used what they needed and simply twisted or cut the other wires off.

* Remove the wires from the terminals on the sub-base. The power should be off so you shouldn't have to worry about being shocked. Be careful not to let the wires fall back into the wall. Sometimes there is just enough wire to reach the terminals and that's it. Try pulling the wires a bit to see if there is more wire behind the wall. Most of the time there is some slack and you can pull the wire out more. Unscrew the sub-base from the wall while holding the wires. When you get the sub-base off wrap the wires around the pencil or pen. This will keep the wires from falling back into the wall.

* Get the new sub-base and compare it to the old one. Hold it up to the wall in the position you want it. Is the old paint that was covered by the old sub-base going to be covered by the new sub-base? If any of the old paint is going to show you may want to make some touch ups now. After finishing with that, put the new sub-base back on the wall in the position you want it. Make sure it is as level as possible. You can use a level to do this. (This is very important especially for mechanical thermostats. It must be level or the mercury switch will not keep the proper temperature settings in the house. Make sure it is level.) Mark the new holes through the sub-base where the screws will go into the wall to fasten the sub-base.

* It is important in this step to have the proper drill bit size for the size of wall anchors you have. Some wall anchor kits come with a bit in them. We recommend the wall anchor kits with the bits in them because it is the perfect size drill bit for the anchors. The bit should be slightly smaller than the anchor. If the bit is bigger the wall anchor will not hold and the possibility exists that the thermostat will fall off the wall. Drill the mounting holes you made for mounting the sub-base. Insert the wall anchors and push them hard with your thumb. Approximately 1/16th of an inch on the lip of the anchor will remain sticking out of the hole. If it is more than that use the butt-end of the screw driver and push it in until just the lip of the anchor remains visible.

* Undo the wires from the pencil or pen and run them through the center of the sub-base. Insert the screws and screw them only snug tight. Get the level and make sure the sub-base is level. When you are sure that it is level, tighten the screws. Be careful not to allow the sub-base to move when you are tightening the screws.

* Using the color code of the wires (or if they didn't match, the color markings you made with masking tape), attach each wire to their proper terminal. Some people like to loop the wire around the terminal screws. This is not necessary. What is necessary is that the wires are attached to the terminals and they are tight. Additionally, make sure that none of the bare wire is touching anything except the terminal.

What Is HVAC?

What is HVAC? You've probably heard of the term from different contractors, engineers, or perhaps colleagues and business partners; but you're still wondering what the initialism means. Well, HVAC ("H-V-A-C" or "H-VAK") stands for Heating, Ventilation, and Air-Conditioning-three closely related fundamental functions found in homes, offices, and other building structures.

The HVAC system is also known as climate control. This is because these three functions are essential in maintaining comfort in every dwelling.

Three Functions of HVAC
Heating is significant in maintaining adequate room temperature especially during colder weather conditions. There are two classifications of heating: local and central. The latter is more commonly used because it is more economical. Furnace or boiler, heat pump, and radiator make up the heating system.

Ventilation, on the other hand, is associated with air movement. There are many types of ventilation, but they all function similarly. Ventilation is necessary to allow carbon dioxide to go out and oxygen to get in, making sure that people are inhaling fresh air. Stagnant air causes the spreading of sickness, usually airborne, and allergies. But it is also essential to maintain an efficient ventilation system, especially in the attics. Insufficient ventilation usually promotes the growth of bacteria and fungi such as molds because of high humidity. It will also decrease the effectiveness of rafter and roof sheathing insulation because of water vapor condensation.

The air-conditioning system controls the heat as well as ventilation. They often come in different sizes. Most air conditioners have large air ducts, so it is better to check out the building first to see if they can be installed. Or else, you can use the split system or remote coils. It is necessary, though, that air ducts are properly cleaned. Pathogens thrive in dirty air ducts. Return-air grills are also vulnerable to chemical, microbiological, and radiological elements. Thus, HVAC return-air grill height should be that it is not accessible but visible for any observation.

The Future of HVAC
How has technology changed in the HVAC field? Well, using PLCs (programmable logic controllers) in HVAC is the trend nowadays. But a great deal of development of the HVAC system lies on the ever-changing technology and continuous innovation. Companies are adopting wireless technology after they found out that networking HVAC controllers, which often use sensors, can eventually cut installation and labor costs. A lot of engineers are also focused on further improving this technology through the use of mesh wireless setup, which will work for both the wireless sensor and wireless controller networks. The only downside of this could probably be the risk of being exposed to RF (radio frequency) radiation.

The installation of an HVAC system is imperative if we want to achieve maximum comfort and be healthy in our homes, office spaces, or other building facilities. But you also need to consider the building size in installing an HVAC system. Optimum efficiency and comfort level are best achieved if the system is appropriate for the size. After all, any ineffective system usually means more incurred costs in the future. You should also see to it that HVAC is carefully integrated to the overall building design so other aspects needed for proper operations, such as cabling, are not sacrificed. The beginning of HVAC is not clear, though as early as second century, a lot of Roman cities were using a central heating system known as hypocaust. This is further popularized during the Industrial Revolution as big factories used it. Now most modern buildings that you see have integrated HVAC.The primary use of HVAC is to regulate room temperature, humidity, and air flow, ensuring that such elements remain within their acceptable ranges. Effective control of such factors minimizes health-related risks. A very humid atmosphere impairs the body's ability to regulate body temperature as it prevents the evaporation of sweat. High humidity also decreases physical strength, which usually leads to fatigue. An unhealthy surrounding can also affect people's thinking abilities. Hypothermia, heat stroke, and hyperpyrexia, among others, are some of the illnesses that may also occur.

Global growth has been beneficial to the HVAC equipment industry. Even in the presence of regulatory measures such as the prohibition of CFCs in most countries and the rise of minimum efficiency requirement, findings still show that demand will increase to 5 percent every year onward as more and more facilities worldwide use HVAC systems. In the United States alone, it is expected that sales will reach up to $14.3 billion in 2009 due to nonresidential construction and residential remodeling.

Thus, they become a well-liked choice for home heating. Chillers are machines that chill water, which then cools and dehumidifies air. They require low electrical power and are typically powered by gas turbines. Steam is often used in absorption chillers. Reciprocating, screw-driven, and centrifugal chillers are the basic varieties. Unitary air conditioners are sold either as a single package or a split system. Units with high efficiency perform similarly with conventional efficiency air models but use less electricity. Packaged terminal air conditioners, meanwhile, include outdoor louvers and heating availability, among others. They are usually mounted on the walls. Another well-liked equipment is fiber glass ducts. These ducts can absorb nice unlike sheet metal air ducts.

These-as well as other HVAC equipment such as boilers or furnaces, exhaust fans, and coils-are available from different manufacturing companies found anywhere around the world. One of them is Lennox. Lennox air-conditioning systems are known for regulating and maintaining indoor air quality. They also distribute refrigeration systems globally. These are primarily used for the preservation of food in restaurants, supermarkets, and warehouses, among others. Another would be Ruud. For over 100 years, they have been servicing residential and commercial facilities with quality HVAC products.
You can also purchase HVAC equipment online. Ebuild.com has one of the most extensive interactive catalogs of HVAC equipment for contractors, builders, and owners alike. If you're looking for air conditioners, for instance, you can actually browse among 340 products and choose your most desired unit through manufacturer and brand preference, nominal tons, refrigerant type, SEER, and energy star compliance. This refined-search method will produce results that will likely suit your style and your needs.

If you wish to purchase HVAC equipment from specific companies, you may refer to Apple Directory and to HVAC-Mall.com. Apple Directory contains a comprehensive alphabetical listing of HVAC equipment and their corresponding manufacturer and seller in the United Kingdom and USA. These are major firms that have proven track record when it comes to good-quality HVAC equipment. HVAC-Mall.com , meanwhile, is helpful when you have the definite equipment in mind since the site showcases companies and their main products. For example, if you want to buy a gas-fired boiler, fluid-to-fluid exchanger, or water heater, you may visit Aerco.com.

For cost-cutting measures, it is advisable that you procure an HVAC equipment without a middleman. Usually, most price quotations from contractors are already marked up to compensate with the other costs they incur in running the business. The problem lies when you aren't sure what equipment to buy, much more its specifications. You may then resort to bidding. Get the most competitive estimates from different contractors, choose the most ideal, and have them buy and install the equipment.

You can also contribute to environment preservation by selecting the most efficient HVAC equipment. They use lesser energy and decrease pollution due to onsite combustion. Furthermore, they last longer. There are limited air-conditioning systems available today that are CFC free. Thus, you prevent the continuous deterioration of our ozone layers. The most popular HVAC equipment used in homes and commercial and industrial buildings are heat pumps, chillers, and unitary and packaged terminal air conditioners. Heat pumps cause heat to move from a lower to a higher temperature reservoir through mechanical means. Vortex tubes, phase-change heat pumps, gas-compression heat pumps, and geothermal-exchange heat pumps are some of the typical kinds. Performance of heat pumps is best compared through their coefficient of performance (COP). This is the term used to explain the relationship between heat output and electrical power utilized. COP of most heat pumps are continuously rising, almost as high as 5.

Fuel oil smell is usually one of a few possibilities.

First and most important is to physically have a look at your heating system and oil tanks and make sure there are no oil leaks! If your system has a front cover over the burner it should be opened to inspect. If you notice a large amount of oil any where I would suggest you shut the switch and call your local Fire Dept, then a qualified service company. If the system has any kind of leaks I would also call a service co.

Hot air furnaces may have the burner mounted around mid point with the fan unit on the bottom. These systems will pick up oil smells and send them through the home rapidly.

Systems should not leak any oil, if there are drips coming from the bottom of the burner motor it is most likely that the pump shaft seal is leaking and needs to be replaced. If the oil lines are wet at the fittings then they need to be sealed.

If the smell is light and you have been noticing this smell for a few days, then it is most likely that your system is puffing back while running and is due for a cleaning.

Fuel oil heating systems should be serviced annually. When a system is serviced it is normally disassembled, cleaned, nozzle and oil filter replaced. A cleaning is not just a light dusting , the sections inside must be brushed, and the soot vacuumed out of the combustion chamber. If this is not done the soot will build on the walls and stop the gasses from going up the chimney. The smoke and soot will soon escape any openings below the flue pipe and enter the home.

My heating system won't start and there is a flashing red light on the burner motor.

If this is the control that has the flashing light, it has a reset button.

This control is a safety that determines if the flame is running properly in your chamber. It will trip to the off position when the fire in the chamber is smoky or no flame at all.

Before pushing the button, make sure that you do not smell heavy raw fuel, or that there is not fuel leaking out from all around your heating system! Never push this button more than 2 times if the system doesn't fire up or run more than 10 minutes each time.

When you push the button listen to the system, a few things happen when a system starts up. The burner motor starts spinning which drives the oil pump and sends oil to the nozzle. The transformer sends 15,000 volts to the electrodes to make spark and light the oil.

Did it light? How can you tell? the flue pipe will get warm within about 15 seconds, it may get up to 600 degrees in just a few minutes (be careful).

Or the button will trip within 45 seconds and the red light will flash again.

If absolutely nothing happened, no clicks, no motors running, your thermostat may be set too low or the wall emergency switch may be off.

If it did try to fire but stopped after 45 seconds it is most likely that,
1. There is no oil in the tank.
2. The oil filter is clogged.
3. The nozzle is clogged.
4. The burner motor is not spinning.
5. The oil pump is not pumping.
6. The transformer is not sparking.
7. The electrode gap is too wide.
8. The photo eye inside the burner my be soot coated or bad.
9. The oil tank has sludge and is blocking the oil flow.

The proper pilot burner orifice must be selected for the gas being used (natural, LP gas) so that the pilot burns with a medium hard flame. This type of flame provides the maximum flame signal.

The flame safeguard control relay will chatter if excess secondary air velocity or a severe draft condition causes the pilot flame to make intermittent contact with the flame electrode (rod) or grounding bracket.

The performance of the pilot assembly can be determined by measuring the flame signal developed with the pilot operating.

The flame signal (current/voltage) measurement requires the use of an appropriate volt-ohmmeter. Most existing Honeywell Flame Safeguard Controls incorporate a flame current jack in the control plug-in amplifier or in the control itself. The flame current measurement can be made with a Honeywell W136A Test Meter, which has a 0 to 25 microampere dc scale. With the W136A selector switch positioned to the 0 to 25 microampere scale, connect the meter leads to the two ends of the meter connector plug, positive (red, +) to positive, negative (black, -) to negative. The Meter Connector Plug part no. 196146 is provided with the W136A Meter. If a W136A Meter or connector plug is not available, a dc ammeter with a 0 to 25 microampere scale can be wired in series with the F lead of the flame detector circuit. A minimum flame current of 2.0 microamperes is considered acceptable.

The Honeywell BCS 7700 and 7800 SERIES Flame Safeguard Control flame signals are measured in dc volts. A 20,000 volt/ohm meter with a 0 to 5 or 10 Vdc scale is recommended for measuring the flame signal of BCS 7700 controls while a one megohm/volt meter is recommended for 7800 SERIES controls.

The minimum acceptable flame signal voltage for the BCS 7700 controls is 2.2 Vdc (maximum expected is 4.98 Vdc). The minimum acceptable flame signal voltage for the 7800 SERIES controls is 1.25 Vdc (maximum expected is 5.0 Vdc). If the flame signal is less than the minimum acceptable for the Honeywell Flame Safeguard Control used, adjust the flame
electrode (rod) to increase the flame signal to at least the minimum acceptable level by loosening the clamp screw and turning the electrode (rod) slightly to the right or left as required. After the flame electrode (rod) is adjusted, check the gap between the ignition electrode and burner tip (Q179A). The gap must be between 1/16 and 3/32 inch.

DtiCorp.com, Honeywell, Gas Pilot Burner Assemblies, Commercial Pilot Burners, C7005A1037

Fort Lauderdale, FL - DtiCorp.com (http://www.DtiCorp.com) is introducing 22 Brand New Honeywell Intermittent Pilot Modules. These ignition modules provide ignition sequence, flame monitoring and safety shutoff for intermittent pilot central furnaces and heating appliances. S8600 and S8660 models provide up to 1.0 A pilot and 1.0 A main valve current rating. S8610 and S8670 provide up to 1.0 A pilot and 2.0 A main valve current rating. Minimum ambient temperature rating is -40° F [-40° C]. Maximum ambient rating is +175° F [+79° C] for S8600, S8660 and for S8610, S8670 used with 1.0 A or less main valve. Maximum ambient rating for S8610, S8670 used with 1.0 to 2.0 A main valve is +165° F [+74° C].
Intermittent pilot systems are used on a wide variety of central heating equipment and on heating appliances such as commercial cookers, agricultural equipment, industrial heating equipment and pool heaters. Some of these applications may make heavy demands on the controls, either because of frequent cycling, or because of moisture, corrosive chemicals, dust or excessive heat in the environment. In these situations, special steps may be required to prevent nuisance shutdowns and premature control failure. These applications require Honeywell Residential Division Engineering review; contact your Honeywell Sales Representative for assistance.
These controls are designed for use on space heating appliances that typically cycle 3 to 4 times an hour during the heating season and not at all during the cooling season. In an application with significantly greater cycling rates and closer to year-round use, we recommend monthly checkout because the controls may wear out more quickly.
Once a module or gas control has been wet, it may operate unreliably and must be replaced. If the appliance is likely to be cleaned with water or steam, the controls and associated wiring should be covered so water or steam flow cannot reach them. The controls should be high enough above the bottom of the cabinet so they will not be subject to flooding or splashing during normal cleaning procedures. If necessary, shield the controls to protect them from splashing water. A NEMA 4 enclosure is recommended for the ignition module.
Over time, dripping water or high ambient humidity can create unwanted electrical paths on the module circuit board, causing the module to fail. Never install an appliance where water can drip on the controls. In addition, high ambient humidity can cause the gas control to corrode, and finally to fail. Where the appliance may be installed in a humid atmosphere, make sure air circulation around the module and gas control is adequate to prevent condensation. It's also important to regularly check out the system.

Fort Lauderdale, FL - Introducing Honeywell-Thermostats.com
(http://www.honeywell-thermostats.com/), a Shopping Assistance
Service for customers buying Honeywell thermostats. Their mission is
to provide the customers with the best service to buy HVAC
thermostats. No one knows thermostats better than Honeywell. Their
heritage is built on over 100 years of thermostat design and
manufacturing. The primary job of a thermostat is to accurately
control home temperature, and that is why Honeywell makes thermostats
that are easy to use, contain high quality components and are
engineered to precise design specifications resulting in pinpoint
temperature control to +/- 1 F. The focus is on quality, performance
and innovation, and it shows in the complete lines of brand new
Honeywell thermostats.

A thermostat is a device for regulating the temperature of a system so
that the system's temperature is maintained near a desired setpoint
temperature. The thermostat does this by switching heating or cooling
devices on or off or regulating the flow of a heat transfer fluid as
needed to maintain the correct temperature. The Honeywell digital
thermostats have no moving parts to measure temperature and instead
rely on thermistors or other semiconductor devices such as a
resistance thermometer (resistance temperature detector). Typically
one or more regular batteries must be installed to operate it,
although some so-called "power stealing" digital thermostats use the
common 24 volt AC circuits as a power source, but will not operate on
thermopile powered "millivolt" circuits used in some furnaces. Each
has an LCD screen showing the current temperature, and the current
setting. Most also have a clock, and time-of-day and even day-of-week
settings for the temperature, used for comfort and energy
conservation. Some advanced models have touch screens, or the ability
to work with home automation or building automation systems. Honeywell
digital thermostats use either a relay or a semiconductor device such
as triac to act as switch to control the HVAC unit. Units with relays
will operate millivolt systems, but often make an audible "click"
noise when switching on or off.

More expensive models have a built-in PID controller, so that the
thermostat knows ahead how the system will react to its commands. For
instance, setting it up that temperature in the morning at 7 a.m.
should be 21°C, makes sure that at that time the temperature will be
21°C, where a conventional thermostat would just start working at that
time. The PID controller decides at what time the system should be
activated in order to reach the desired temperature at the desired
time. It also makes sure that the temperature is very stable (for
instance, by reducing overshoots). Most Honeywell digital thermostats
in common residential use in North America and Europe are programmable
thermostats, which will typically provide a 30% energy savings if left
with their default programs; adjustments to these defaults may
increase or reduce energy savings.

Fort Lauderdale, FL - DtiCorp.com (http://www.DtiCorp.com) is introducing 27 Brand New Honeywell Programmable Thermostats. Heating and cooling losses from a building become greater as the difference in temperature increases. A programmable thermostat allows reduction of these losses by allowing the temperature difference to be reduced at times when the reduced amount of heating or cooling would not be objectionable.

Honeywell Programmable Thermostats provide the ability to automatically adjust for unique lifestyles, controlling home comfort to the desired temperature at the desired time. They do the work for the homeowner automatically when they are away or asleep. And the big benefit is energy savings - up to 30% on home heating and cooling costs - by adjusting the temperature up or down, thereby reducing equipment run-time. Honeywell combines the convenience of schedule selection with precise temperature control to deliver superior programmable thermostats.
During the air conditioning season, a programmable thermostat used in a home may be set to allow the temperature in the house to rise during the workday when no one will be at home. It may then be set to turn on the air conditioning before the arrival of occupants, allowing the house to be cool upon the arrival of the occupants while still having saved air conditioning energy during the peak outdoor temperatures. The reduced cooling required during the day also decreases the demands placed upon the electrical supply grid.
With the difference in temperature between interior and exterior being reduced, it is not unusual to achieve 30% energy usage reductions with the default program on residential thermostats, though adjusting the default settings may improve or reduce energy usage.
