Air Handlers - One Hour

 


Air handlers are an important component to any heating and air conditioning system. Usually, an air handler is a large metal box containing a blower, heating and/or cooling elements, filter racks or chambers, sound attenuators, and dampers. Air handlers usually connect to ductwork that distributes the conditioned air through the home, and returns it to the air handler. Sometimes air handlers discharge and admit air directly to and from the space served, without necessary ductwork.

Air handlers typically are comprised of:

Blower/fan is usually located in a large squirrel cage blower driven by an electric motor to move the air. The blower may operate at a single speed, offer a variety of pre-set speeds, or be driven by a variable drive so as to allow a wide range of air flow rates.

Heating and/or cooling elements provide heating or cooling, or both to change the supply air temperature depending on the location and the application.

Filters are almost always present and needed in order to provide clean dust-free air to the home interior.

Humidifier is often necessary in colder climates where continuous heating will make the air drier, resulting in uncomfortable air quality and increased static electricity.

Mixing chamber is used to maintain indoor air quality, some air handlers commonly allow the use of outside air into, and the exhausting of air from the home. A mixing chamber is used with dampers to control the ratio between the return, outside, and exhaust air.

Controls are necessary to regulate every aspect of an air handler, such as: flow rate of air, supply air temperature, mixed air temperature, humidity, air quality. Common control components include temperature sensors, humidity sensors, sail switches, actuators, motors and controllers.

Vibration isolators are inserted into the duct immediately before and after the air handler and often also between the fan compartment and the rest of the air handler to help reduce the effects of the vibration from the air handler.

An air handler is usually located in the garage, a closet, or in the attic unless it is part of a package unit, then the air handler is incorporated in the system. The air handler can be an up flow air handler, down flow air handler, or horizontal flow air handling unit.
