METHOD AND AGGREGATE FOR OPTIMIZING THE HEAT ECONOMY IN BUILDINGS BY MEANS OF A HEAT PUMP

摘要

Abstract of the DisclosureA method and an aggregate for heating and cooling buildings and/orthe preparation of warm household water by means of a heat pump.The method comprises the steps of recovering heat from exhaust airand from the water vapour present in said air, letting the vaporizerof the heat pump become frosted, and intermittently defrosting thevaporizer.The compressor of the heat pump is operated at least approxi-mately with a constant output, such that the operating time thereof isat least 4500 h/year. The condensation takes place both by meansof a water and an air condenser, and the vaporizer is defrosted bymeans of the exhaust air while the compressor is stopped and theexhaust air fan is operating.
