ABSTRACT:
A ventilating system which affords recuperative heat exchange between the supply air and the spent air and which incorporates a refrigerating machine as a heat pump which may be operated either to supplement the recuperative heat exchange or to cool the supply air without recuperative heat exchange between the supply air and the spent air. The system includes a heat exchanger in the supply-air duct and a second heat exchanger in the spent-air duct. The two heat exchangers are interconnected in a fluid circuit so that during the heating season, the fluid is heated by the spent air to warm the supply air. When the refrigerating machine is operting as a heat pump, the fluid discharged from the supply-air heat exchanger is passed through the evaporator and the fluid passing from the spent-air exchanger to the supply-air exchanger is passed through the condenser. In the cooling season, the fluid circuit circulates the fluid in the supply air through the evaporator and the spent-air heat exchanger is connected to the condenser. This system may also supplement the supplied air with recirculated spent air, or may supplement the spent air with fresh outside air.
