Abstract: A refrigeration cycle includes a compressor, a refrigerant radiator, first and second expansion valves configured to decompress refrigerant flowing out of the refrigerant radiator, a first evaporator configured to evaporate the refrigerant flowing out of the first expansion valve, and a second evaporator configured to evaporate the refrigerant flowing out of the second expansion valve. A heat medium circuit includes a heat exchange portion and circulates a heat medium while flowing through the heat exchange portion and the second evaporator. The first evaporator exchanges heat between the refrigerant and ventilation air blown to a space to be air conditioned, and the second evaporator exchanges heat between the heat medium and the refrigerant to evaporate the refrigerant and cool the heat medium. The heat exchange portion is made to cool the temperature regulation target.

Abstract: A first refrigeration cycle includes a first compressor, a first radiator, an air-conditioning expansion valve, an air-conditioning evaporator, a first expansion valve, and a first evaporator. In the first refrigeration cycle, a first refrigerant evaporates in at least one of the air-conditioning evaporator or the first evaporator. A second refrigeration cycle includes a second compressor, a second radiator, a second expansion valve, and a second evaporator. A heat transfer portion switches a heat radiation destination from the first radiator to a second refrigerant in the second evaporator or outside air. In the air-conditioning evaporator, the first refrigerant absorbs heat from ventilation air blown into a space to be air conditioned as the first refrigerant evaporates. In the first evaporator, the first refrigerant absorbs heat from the outside air as the first refrigerant evaporates. In the second radiator, the second radiator radiates heat from the second refrigerant to the ventilation air.
