Title:
COOLING SYSTEM FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/138732
Kind Code:
A1
Abstract:
This cooling system (1) for a vehicle is provided with: a common flow passage (10), through which a refrigerant flows; an air conditioning flow passage (20) which has an air conditioning opening/closing valve (21) and an air conditioning heat exchanger (23); and a cooling flow passage (30) which has a cooling opening/closing valve and a cooling heat exchanger (33). The cooling system for a vehicle is provided with a control unit (50) which controls the air conditioning opening/closing valve to be in a closed state and controls the cooling opening/closing valve to be in an open state when there is a request for cooling, by which cooling is to be performed by using the cooling heat exchanger and an ambient temperature, which is a temperature at an upstream side of an air flow with respect to the air conditioning heat exchanger, is lower than a lower limit temperature. That is, the refrigerant does not flow to the air conditioning flow passage but flows to the cooling flow passage, when heat enough to vaporize the refrigerant cannot be obtained in the air conditioning heat exchanger. Accordingly, the refrigeration operation by using the cooling flow passage can be stably maintained by reducing an operation failure, such as a liquid back to the compressor (11) or the like.
