UNITARY HEAT EXCHANGER FOR THE AIR-TO-AIR TRANSFER OF WATER VAPOR AND SENSIBLE HEAT

摘要

A unitary heat exchanger device, for the transfer of total heat, comprisingair-to-air heattransfer means and configured such that air may pass there through. The heattransfer meanscomprisesan air-to-air water vapor transfer elementandan air-to-air sensible heat transfer element,the exchanger elements being in air communication with each other. The devicemay be usedin ventilation systems which replace air exhausted from the interior of abuilding with freshoutside air, the use of the device under cold weather conditions may avoid orattenuate the needfor using a defrost mechanism to defrost the device.
