HEAT EXCHANGE AND VENTILATION DEVICE

摘要

A heat exchange ventilation apparatus in which a supply air passage that suctions outdoor air from an outdoor-side inlet by a supply air blower and supplies to an inside of a room from an indoor-side outlet through a supply-air heat exchange passage of a heat exchanger and an exhaust air passage that suctions indoor air from an indoor-side inlet by an exhaust air blower and discharges to an outside of the room from an outdoor-side outlet through an exhaust-air heat exchange passage of the heat exchanger are formed in a rectangular parallelepiped casing, only one surface of the supply air blower is screwed onto one surface of the casing, and other surfaces of the supply air blower are supported on an inner surface of an integrally-molded suction chamber that accommodates the supply air blower and forms part of the supply air passage.
