Abstract: An embodiment integrated-type air-conditioning system includes a refrigerant circuit including first and second refrigerant lines, a first coolant circuit including a battery, and a second coolant circuit including a PE part. The first refrigerant line includes a compressor, an indoor heat exchanger, a first expansion device, and an outdoor heat exchanger, and the second refrigerant line includes a second expansion device and an integrated heat exchanger. The second refrigerant line branches from a branch point between the indoor heat exchanger and the first expansion device in the first refrigerant line and branches from a point between the compressor and the indoor heat exchanger through a switching valve to be connected to the compressor. The first coolant circuit and the second coolant circuit are each connected to the integrated heat exchanger so as to allow a coolant to exchange heat with a refrigerant.

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.

Abstract: A thermal management system includes a circulation channel that connects a motor cooler, outside air heat exchanger, and a heater, a switching valve, and a controller. In a heating mode of operating the heater, the controller sets the switching valve in the first valve position when the motor temperature is lower than a motor temperature threshold value, and sets the switching valve in the second valve position when the motor temperature is higher than the motor temperature threshold value. When a load or a load predicted value of the motor exceeds a load threshold value, the controller holds the switching valve in the second valve position during a predetermined holding time.
