Refrigerating apparatus

A refrigerating apparatus comprising:

• a first refrigeration cycle circuit including a first compressor, a first radiator, a supercooler, a first pressure-reducing device and an evaporator that are successively connected to one another through a refrigerant pipe;
• a second refrigeration cycle circuit including a second compressor, a second radiator, a second pressure-reducing device and the supercooler that are successively connected to one another through a refrigerant pipe, refrigerant of the first refrigeration cycle circuit being supercooled by vaporization action of the second refrigeration cycle circuit in the supercooler, and hot-water supply water being warmed by heat radiation action of refrigerant of the second refrigeration cycle circuit in the second radiator;
• a refrigeration unit in which the first compressor and the first radiator are mounted;
• a showcase in which the first pressure-reducing device and the evaporator are mounted;
• a supercooling hot water supply device in which the second compressor, the second radiator, the second pressure-reducing device and the supercooler are mounted;
• and
• a hot-water stock device having a hot water supply tank that is connected to the second radiator of the supercooling hot water supply device through a second radiator.
