You probably know that you have an HVAC system for your facility, but you might not know what all of the components do. Here is a list of the most common HVAC elements found in a commercial building and how they work together to keep your building at its ideal temperature. An air conditioner is designed to dehumidify and remove heat from an area. The cooling is done using a simple refrigeration cycle. A condenser is a component of the basic refrigeration cycle that removes heat from the system. The condenser is the hot side of an air conditioner. Condensers are heat exchangers that can transfer heat to air or heat to fluid (such as water or glycol) to carry the heat away.

An air handler, or air handling unit (often called an AHU), is used to condition and circulate air as part of an HVAC system. An air handler usually contains a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers. Air handlers usually connect to ductwork that distribute the conditioned air through the building and return it to the AHU. Small air handlers are called terminal units, and may only include an air filter, coil, and blower. These smaller units are also called blower coils or fan coil units. An air handler designed for outdoor use, typically on roofs, is known as a rooftop unit (RTU). A chiller removes heat from a liquid through a vapor-compression or absorption refrigeration cycle. This cooled liquid flows through pipes in a building and passes through coils in air handlers, fan-coil units, or other systems, cooling and usually dehumidifying the air in the building. There are two types of chillers – air-cooled or water-cooled.

Air-cooled chillers are usually outside and consist of condenser coils cooled by fan-driven air. Water-cooled chiller are usually inside a building, and heat from these chillers is carried by re-circulating water to a heat sink such as an outdoor cooling tower. Now that you know the difference between these components, do you remember when the last time was that you had them tuned up? Be sure to perform regular facility HVAC maintenance to keep your system running at its peak.

But having the HVAC system is not enough. You will also need to make sure that it is in proper working condition all the time if you want it to serve you best. It is therefore very important for you to learn basic facts about the essential components of this system and know the roles they play in maintaining comfortable temperatures in your home.

One of the most important components of the HVAC system is the thermostat. It is the most visible part of this system that is usually set on a prominent and easily accessible wall. You can either program it in advance or set it manually to maintain desired temperatures in your home. In the event that the temperatures in your home become too cold, the thermostat will trigger the heat exchanger to start circulating warm air as needed so as to prevent you from freezing. If the temperatures are too hot, the thermostat will trigger the evaporator coil condensing unit to start circulating cooled air in your home. The furnace is another very important component of the HVAC system. It is quite large, and as a result it requires substantial space. The based places that you can put it in your home include the attic, your finished basement, the cellar, or a special closet that is specifically designed for it. It is responsible for heating the air that is distributed to various rooms via the HVAC system.

The heating process is accomplished using a heat pump, electric resistance, combustion or solar energy. Another important component of the HVAC system is the heat exchanger. It is usually located inside the housing unit of the furnace. It switches on when the furnace is activated by the thermostat so as to produce warmer temperatures when it is too cold. It does this by pulling in cool air, heating it and then circulating it via ducts as well as out through the vents. The opposite role is played by another important component known as the evaporator coil. It works similarly to an automobile radiator and is responsible for producing cool air. The condensing unit is also a very important component of the HVAC system. It is usually connected to the evaporator coil and is installed on the outside of the home. After the heat exchanger has cooled the refrigerant to a liquid, this unit pumps the liquid to the evaporator coil so that it can be evaporated into a gas again. The ductwork is another very important unit of the HVAC system.
