REFRIGERATION CIRCUIT DEVICE

WIPO Patent Application WO/2023/176380

A1

A first refrigeration cycle (10) provided to this refrigeration circuit device has a first compressor (101), a first radiator (102), an air-conditioning expansion valve (106), an air-conditioning evaporator (107), a first expansion valve (108), and a first evaporator (109). In the first refrigeration cycle, a first refrigerant evaporates in the air-conditioning evaporator and/or in the first evaporator. The second refrigeration cycle (20) has a second compressor (201), a second radiator (202), a second expansion valve (203), and a second evaporator (204). A heat transfer part (30) switches the destination of heat radiation from the first radiator to a second refrigerant in the second evaporator or to the outside air. In the air-conditioning evaporator, in association with the evaporation of the first refrigerant, the first refrigerant absorbs heat from air to be blown to a space (68) to be air-conditioned, whereas in the first evaporator, in association with the evaporation of the first refrigerant, the first refrigerant absorbs heat from the outside air, and the second radiator radiates heat from the second refrigerant in the second radiator to the blown air.
