Air exchangers work by circulating stale indoor air out of your home and circulating in fresh air from outside.
Air to air exchanger. There are several types of air to air heat exchangers with mean recovery efficiencies from 50 up to 90 depending the type of heat exchanger and the outdoor and indoor air conditions temperatures and humidity. From all types of air to air heat exchangers the most used in air handling units applications are. Hvac heat exchangers explained the basics working principle how heat exchanger works duration. Counter flow heat exchangers consist of a core of flat plates.

Air exchangers are a great solution to indoor air quality problemsespecially when the cold forces you to stay indoors. The air to air welded is suited for applications with higher temperatures higher pollution and higher external loads on the heat exchanger fully customized to fulfill the individual customer needs. Heat transfers through the plates to the cooler air. The percentage of heat recovery is the efficiency of the unit.
Tom heylen 56245 views. Exchangers use one fan and vent system to blow indoor air outside while another sucks fresh air in. The stale air gets sent to the outside while the new air is sent to the inside. The longer the air runs in the unit the greater the heat exchange.
Generally these units are long shallow and rectangular with ducts at either of the long ends. Diy air heat exchanger pvc pipe and soda cans duration.
