Abstract
A heat exchange system for a vehicle includes a refrigerant circulation loop for circulating a refrigerant, a compressor, a condenser, a first expansion valve, a second expansion valve, a first chiller and a second chiller. The first expansion valve and the first chiller form a group and the second expansion valve and the second chiller form another group. The two groups are arranged in parallel; a first coolant circulation loop comprising a first cooler, and circulating coolant which exchanges heat with the refrigerant via the first chiller; a second coolant circulation loop includes a second cooler, and circulating coolant which exchanges heat with the refrigerant via the second chiller. The first expansion valve and the second expansion valve are controlled so that the refrigerant passing through the first chiller during a cooling mode has a higher pressure, temperature, and rate of discharge than the refrigerant passing through the second chiller.
