1. A vehicle heat management system comprising:
a refrigerant circuit configured to circulate a refrigerant to regulate a temperature inside a passenger compartment therethrough;
a battery temperature regulation circuit configured to regulate a temperature of a battery by introducing a liquid that exchanges heat with the refrigerant to the battery, the battery temperature regulation circuit comprising a first control valve on a downstream side of the battery and a heat exchanger on a downstream side of the first control valve and configured to exchange heat with the refrigerant;
an electric part cooling circuit configured to circulate a liquid cooled by a radiator therethrough, the electric part cooling circuit being capable of cooling a first piece of equipment and a second piece of equipment for driving a vehicle; and
a first bypass channel configured to introduce the liquid of the battery temperature regulation circuit to the second piece of equipment, wherein
in a first mode, the liquid cooled by the radiator cools the first piece of equipment, the liquid which has exchanged heat with the refrigerant is introduced in parallel to the battery and the second piece of equipment, and the first control valve is open such that the liquid which has flowed out from the battery and the second piece of equipment flows through the first control valve, and
in a second mode, the first control valve is closed such that the liquid does not flow through the first control valve, and the liquid which has exchanged heat with the refrigerant is introduced in series to the battery and the second piece of equipment such that the liquid flowing out from the battery passes through the first bypass channel and is introduced to the second piece of equipment.
