HEAT EXCHANGER

摘要

Disclosed is a heat exchanger comprised of a plurality of electric motors, exhaust fan casings, air supply fan casings, heat exchange elements, air supply paths, and exhaust paths, wherein first stack pitches between heat transfer plates of heat exchange elements which are disposed at positions excluding a position adjacent to an outdoor intake port in each air supply path and a position adjacent to an indoor intake port in each exhaust path are smaller than second stack pitches between heat transfer plates of heat exchange elements which are disposed at the position adjacent to an outdoor intake port in each air supply path and the position adjacent to an indoor intake port in each exhaust path.
