Abstract: A refrigeration cycle device including a first pressure reducing valve, a first evaporator that exchanges heat between the refrigerant decompressed in the first pressure reducing valve and air, a second pressure reducing valve that is disposed in parallel with the first pressure reducing valve; a second evaporator in which the refrigerant decompressed in the second pressure reducing valve to absorbs heat from a battery; a third pressure reducing valve that reduces the pressure of the refrigerant evaporated in the second evaporator; and a controller configured to control opening degrees of the second pressure reducing valve and the third pressure reducing valve. The controller performs a limit control for controlling the opening degree of the second pressure reducing valve to an opening degree of smaller one of a battery cooling opening degree and an air cooling opening degree.

Abstract: In a thermal management system, a low-temperature side heat medium circuit includes a first circuit, a second circuit, a coupling part, and a flow rate adjustment part. The first circuit includes a first heat exchange unit, and is configured such that a heat medium can circulate via a chiller and the first heat exchange unit. The second circuit includes a second heat exchange unit, and is configured such that the heat medium can circulate via the second heat exchange unit and a heat medium pump. A controller controls an operation of the flow rate adjustment part and adjusts the flow rate of the heat medium in the coupling part, so as to make a temperature zone of the heat medium flowing through the first circuit and a temperature zone of the heat medium flowing through the second circuit have respective determined values.

Abstract: An air conditioner is configured to be switchable between a heating mode and a cooling mode. In the cooling mode, a high-temperature heat medium circulates between a high-pressure side refrigerant-heat medium heat exchanger and a high-temperature heat medium-outside air heat exchanger in a state where a refrigerant circulates in an air-cooling heat exchanger. In the heating mode, the high-temperature heat medium circulates between the high-pressure side refrigerant-heat medium heat exchanger and an air-heating heat exchanger, while a low-temperature heat medium circulates between a low-pressure side refrigerant-heat medium heat exchanger and a low-temperature heat medium-outside air heat exchanger, in a state where the refrigerant circulates in the low-pressure side refrigerant-heat medium heat exchanger.
