Save. HVAC is an abbreviation for Heating, Ventilation and Air Conditioning. HVAC systems are the main mechanical infrastructure of a building and provide climate control functions. An HVAC system can range from a compact unit placed in a window sill to a multisystem unit that is installed on a roof or in a basement.HVAC systems are typically the most costly elements of construction.eatures. An HVAC system has the ability to pump hot, cold or fresh air into an area. It pulls fresh air from the outside and then alters it to the desired temperature. Often HVAC systems use hot or cold water to either chill or heat the air.
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.n air conditioner is designed to dehumidify and remove heat from an area.
