Abstract
A unitary heat exchanger device, for the transfer of total heat, comprising air-to-air heat transfer means and configured such that air may pass there through. The heat transfer means comprises an air-to-air water vapor transfer element and an air-to-air sensible heat transfer element, the exchanger elements being in air communication with each other. The device may be used in ventilation systems which replace air exhausted from the interior of a building with fresh outside air; the use of the device under cold weather conditions may avoid or attenuate the need for using a defrost mechanism to defrost the device.
