VEHICULAR HEAT MANAGEMENT SYSTEM AND CONTROL METHOD THEREFOR

WIPO Patent Application WO/2018/164032

A1

[Problem] The purpose of the present disclosure is to provide a vehicular heat management system and a control method therefor such that even when a refrigerant is not condensed due to insufficient heat dissipation by a WCDS, a condensed refrigerant can be obtained. [Solution] The vehicular heat management system 1 pertaining to the present invention is provided with: a first loop 10 for circulating a liquid heat medium to heat-generating bodies 12, 13, 14 to cool the heat-generating bodies; a second loop 20 for circulating a refrigerant to a cooling heat exchanger 23; and a refrigerant condenser 30 for exchanging heat between liquid heat medium flowing in the first loop and the refrigerant flowing in the second loop. The second loop comprises: a compressor 21, a refrigerant condenser, an expansion device 22, and the cooling heat exchanger 23 which are disposed in sequence in a refrigerant flow direction; and an internal heat exchanger 40 for exchanging heat between a first heat exchanger 41 through which the refrigerant led from the refrigerant condenser to the expansion device flows and a second heat exchanger 42 through which the refrigerant led from the cooling heat exchanger to the compressor flows.
