ABSTRACT:
A ventilation system comprising a heat-exchanger rotor mounted in a four-chamber housing supported on a panel or window unit, and a preliminary heat-exchange unit mounted at an air-intake portion of the housing. The window unit has a frame composed of a plurality of hollow structural sections defining a heat-medium passageway for circulation of heat medium such as hot water or cold water therethrough. The preliminary heat-exchanger unit has a radiation/endothermy tube connected to the heat-medium passageway for fluid communication therewith. The radiation/endothermy tube serves to prewarm or precool air (introduced from the exterior) before the latter passes through the heat-exchanger rotor.
