  • Refrigeration apparatus and temperature control apparatus
    Patent number: 11391497
    Abstract: A refrigeration apparatus includes first and second refrigeration circuits, and a supercooling circuit. The supercooling circuit includes a supercooling bypass flow path which communicates a part of the first refrigeration circuit positioned on the downstream side of the condenser and on the upstream side of the first expansion valve, to a compressor on the first refrigeration circuit; a supercooling control valve; and a supercooling heat exchanger disposed on the downstream side of the supercooling control valve in the supercooling bypass flow path. The supercooling heat exchanger is configured to cool the refrigerant flowing through a part of the first refrigeration circuit, on the downstream side of a connection position to the supercooling bypass flow path. The second refrigeration circuit includes: a branch flow path which branches from a part of the first refrigeration circuit, on the upstream side of the connection position to the supercooling bypass flow path.
