Abstract:
1. A cooling heating device which is provided with a vapor compression type refrigeration cycle including a refrigerant circuit constituted by successively connecting a compressor, a condenser, throttle means and an evaporator and which heats a heat target by use of a heat radiating function of a refrigerant in the condenser and which cools a cool target by use of a heat absorbing function of the refrigerant in the evaporator, the device comprising: an auxiliary heat exchanger having one end connected to a refrigerant outlet-side pipe of the condenser via the throttle means and having an other end connected to a suction-side pipe and a discharge-side pipe of the compressor and configured to perform heat exchange between the refrigerant and a heat source other than the heat target and the cool target; channel changeover means for executing control so as to pass the refrigerant discharged from the compressor through the condenser or the auxiliary heat exchanger and supply the refrigerant from the auxiliary heat exchanger to the compressor or supply the refrigerant from the evaporator to the compressor; control means for controlling the compressor, throttle means and the channel changeover means based on a cooling operation signal in response to a cooling load of the cool target and a heating operation signal in response to a heating load of the heat target; heating-side pump means for circulating a heating-side heat medium to perform heat exchange between the condenser and the heating-side heat medium constituting the heat target; heating-side flow rate adjustment means for adjusting a flow rate of the heating-side heat medium; heating-side temperature detection means for detecting a temperature of the heating-side heat medium subjected to the heat exchange between the heating-side heat medium and the condenser; and a heating-side connection port to be connected to a circulation path of the heating-side heat medium.
