Abstract
An air exchanger for continuously exchanging indoor air with outdoor air to provide a constant supply of fresh air into a structure which includes a heat exchanger having a continuous structure which defines adjacent first and second sets of channels which open toward opposite sides of the air exchanger. The air exchanger draws outdoor air through the first set of channels in a first direction and indoor air through the second set of channels in a second, counter-direction. Heat is transferred between the indoor and outdoor air streams such that when the outdoor air enters the room, its temperature approaches the indoor temperature and indoor heating or cooling effects are minimized.
