PCT No. PCT/SE80/00085 Sec. 371 Date Nov. 20, 1980 Sec. 102(e) Date Nov. 20, 1980 PCT Filed Mar. 21, 1980 PCT Pub. No. WO80/02064 PCT Pub. Date Oct. 2, 1980.A heat exchanger in combination with two duct system for bringing in relatively cold outside air into an enclosure while exhausting relatively warm room air from the enclosure. The heat exchanger is positioned so as to recover heat from the exhaust air into the incoming cold fresh air. A valving system switches the incoming cold air with the warm exhaust air in the flow paths of the heat exchanger. This solves the problem of moisture from the exhaust air condensing on the walls of the ducting system for the exhaust air.
