摘要

TITLE EXHAUST AIR HEAT EXCHANGER INVENTORS Ewart Brundrett Laurence Brundrett A heat exchanger for exchanging heat between incoming cold fresh air and outgoing warm exhaust air, The heat exchanger is constructed of a number of relatively long flexible plastic tubes supported within a flexible plastic outer housing. The inner tubes are supported in spaced-apart relationship within the outer housing. A manifold on each end of the tubes in sealing engagement with the inner tubes and with the housing so that air can be forced through the inner tubes in one direction and through the housing in the other direction. The diameters of the inner tubes and outer housing being large enough so that blockage by ice or frost is minimized.
