<P>PROBLEM TO BE SOLVED: To provide a vehicle temperature control system configured to improve heating performance with a simple configuration. <P>SOLUTION: The vehicle temperature control system 10 includes a main refrigerant circuit 13 and an electrical component cooling flow path 15. The main refrigerant circuit 13 includes a compressor 80, a four-way valve 81, an outside-air heat exchanger 82 for exchanging heat with the outside air, an air-conditioning heat exchanger 87 for conditioning the air in the vehicle, and an air-conditioning control valve 83. The electrical component cooling flow path 15 includes a cooling unit 42 for cooling an electrical component 41, a heater 46 for heating refrigerant, and a pump 43 for allowing the refrigerant flowing in the cooling unit to flow into an outlet-side refrigerant piping 13c. The electrical component cooling flow path 15 connects a first refrigerant piping 13a, a second refrigerant piping 13b, and the outlet-side refrigerant piping 13c, where liquid refrigerant flows, in the main refrigerant circuit 13. The heater 46 is arranged between a contact point A between the electrical component cooling flow path 15 and the outlet-side refrigerant piping 13c, and the cooling unit 42. <P>COPYRIGHT: (C)2013,JPO&INPIT |
