Abstract: In a heat pump system, when a heat-shock determination portion determines that a difference between a coolant temperature in a coolant flow path and a coolant temperature in a heat source flow path is equal to or higher than a predetermined temperature, a flow-path switching portion mixes the respective coolants flowing through at least a bypass flow path and the heat source flow path together to flow into the coolant flow path.

Abstract: A battery warming-up system includes a controller that controls an air-conditioning blower and a battery blower. A battery warming-up mode is executed to control at least one of the air-conditioning blower and the battery blower such that an air-side temperature efficiency in an air-conditioning heat exchanger is higher than an air-side temperature efficiency in a battery heat exchanger.

Abstract: A vehicular temperature regulation device includes a refrigeration cycle, a high-temperature cycle, and a low-temperature cycle. The refrigeration cycle includes a heating heat exchanger configured to heat the heat medium in the high-temperature cycle by exchanging heat between the refrigerant and the heat medium, and a cooling heat exchanger configured to cool the heat medium in the low-temperature cycle by exchanging heat between the refrigerant and the heat medium. The vehicular temperature regulation device includes a connection portion that connects the high-temperature cycle and the low-temperature cycle, a regulation portion configured to regulate a flow of the heat medium, and a controller. After the controller stops the compressor, or after the controller receives a stop command of stopping the compressor, the controller controls the regulation portion, a first pump, and a second pump to exchange the heat medium between the high-temperature cycle and the low-temperature cycle.

Abstract: A refrigeration cycle device includes a compressor, an air-refrigerant heat exchanger that exchanges heat between air and refrigerant, an expansion valve decompressing the refrigerant, a heat medium-refrigerant heat exchanger that exchanges heat between a heat medium and the refrigerant, a cold-heat utilization device that utilizes cold heat of the heat medium, and a hot-heat utilization device that utilizes hot heat of the heat medium. A refrigerant flow switching valve is provided to switch between a heat-medium cooling mode of cooling the heat medium in the heat medium-refrigerant heat exchanger, and a heat-medium heating mode of heating the heat medium in the heat medium-refrigerant heat exchanger. In addition, a heat medium flow switching device is provided such that, in the heat-medium cooling mode, the heat medium circulates between the heat medium-refrigerant heat exchanger and the cold-heat utilization device, and that in the heat-medium heating mode, the heat medium circulates between the heat medium-refrigerant heat exchanger and the hot-heat utilization device.
