Abstract:
1. A heat control system comprising a heat generator in which heat is generated during operation and a temperature is maintained in a predetermined range, a vapor compression type refrigerator having a compressor, a radiator, an evaporator and a pressure reducing means to transfer heat from a lower temperature side to a higher temperature side, a heat exchanger for exchanging heat between refrigerant discharged from the compressor and prior to being fed into the radiator and medium for exchanging heat with the heat generator, and a bypass connected between the outlet of the radiator and the outlet of the compressor to cause the refrigerant prior to being fed into the evaporator to flow serially through the heat exchanger and the radiator while detouring the evaporator and the compressor, wherein the heat control system includes means for operating in a heating mode for heating the medium with the high-temperature refrigerant discharged from the compressor, and a heat dissipation mode for cooling the medium with the refrigerant discharged from the compressor and dissipating heat absorbed from the medium via the radiator, and during the heat dissipation mode, at least a part of the refrigerant flowing out from the radiator is made to pass through the bypass.
