Abstract

PURPOSE: To make possible the efficient operation of cooling and heating mechanisms by a constitution wherein a cooling and heating cycle circuit is constructed by connecting together in a ring shape a compressor, a four-way valve, an indoor heat exchanger, pressure-reducing mechanism, outdoor heat-exchanger and a cooling medium heater having a heater for heating the cooling medium.
CONSTITUTION: A compressor 1, a four-way valve 2 and an indoor heat exchanger 3 function as an evaporator at the time of air cooling and as a condenser at the time of air heating. A cooling medium flows into a primary pressure-reducing mechanism 4 and a secondary pressure-reducing mechanism 5 so that the pressure of the medium is reduced at the time of air cooling and at the time of air heating when a heat pump is operated to utilize the open air heat source with a relatively high temperature. An outdoor heat exchanger 6 functions as a condenser at the time of air cooling and as an evaporator as the time of air heating, when the heat pump is operated. A cooling medium heater 7 functions as an evaporator at the time of air heating when the open air temperature is low. An open valve 8 is opened to let the cooling medium flow in case the cooling medium heater is used to function as the evaporator at the time of air heating when the open air has a low temperature.
