In a heating, ventilation and air condition system, the device responsible for the distribution of air in any building structure is the HVAC air handler. It is the air handler that manages the indoor air to make every room conditioned at just the right temperature, air purity level and humidity. Either installed within the building or outside, an HVAC air handler is used in connection with air conditioners and heat pumps.
An HVAC air handler is an integral component of an HVAC system. It is a metal box containing a motor fan, and heating and cooling elements. Some air handlers even consist of filters, dampers, compressors, control units and humidifiers.
Once the fresh, outside air is drawn inside the air handler, the refrigerant within cools the air. The cooled air is then conveyed by a blower mechanism into the duct system of the building to cool the air in every rooms covered by the system.
The return ducts are another duct system responsible for drawing exhaust air from the room and into the air handler. Within the unit, the refrigerant removes the heat from the air and directs it towards the outdoor compressor. After the heat removal, the refrigerant returns to the air handler in order to cool the air and do again the cooling process. For winter heating, the system functions in reverse.
