Claim 0:
1. A vehicular heat exchange system comprising:
a first heat exchanger for causing heat to be exchanged between a refrigerant and air in an interior of a vehicle;
a heating circuit for causing the refrigerant with a temperature higher than a temperature of the air in the interior of the vehicle to circulate through the first heat exchanger;
a rechargeable battery where charging and discharging of power are performed;
a cooling water circuit for causing cooling water that exchanges heat with the rechargeable battery to circulate;
a second heat exchanger for causing heat to be exchanged between the refrigerant and the cooling water, the second heat exchanger being provided in a manner including a portion of the heating circuit downstream of the first heat exchanger and a portion of the cooling water circuit;
a case for covering the rechargeable battery, the cooling water circuit, and the second heat exchanger;
a third heat exchanger for causing heat to be exchanged between the refrigerant and air outside the vehicle; and
a compressor for compressing the refrigerant flowing from the third heat exchanger, and causing the refrigerant to flow through the first heat exchanger, wherein
the heating circuit is a heat exchange circuit where the third heat exchanger causes heat to be exchanged between the refrigerant flowing from the first heat exchanger and the air outside the vehicle, and then, the compressor compresses the refrigerant flowing from the third heat exchanger and causes the refrigerant to flow through the first heat exchanger, and
the third heat exchanger is connected in parallel with the second heat exchanger.
