If we look for air conditioning in Collins English Dictionary, it states: âA system for controlling the temperature and humidity of the air in a building.â. Controlling the temperature is being able to heat and cool.Not only cool. Control Humidity (moisture content in the air), either humidify (add moisture) when dry, which can result in dryness of skin, dry throat and encourages static build-up) or de-humidify (remove moisture) when the amount of moisture in the air is high, which can result in breathing discomfort.
An air handler is usually a large metal box containing a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers. Air handlers usually connect to a ductwork ventilation system that distributes the conditioned air through the building and returns it to the AHU. When the air handling unit is in cooling mode, heat is released as air passes through the matrix in the exhaust airstream, during one half rotation, and absorbed during the second half rotation into the supply airstream. 2  Heat recovery efficiency up to 85%.
