Abstract

The present invention provides a refrigerating apparatus that can supply hot water by effectively using waste heat when foods, etc. are cooled, enhance cooling capacity (performance) and cooling efficiency and also perform high-efficient operation in accordance with a load variation of cooling and hot water supply. The refrigerating apparatus including a first refrigeration cycle circuit having a first compressor, a first radiator, a supercooler, a first pressure-reducing device and an evaporator that are connected through a refrigerant pipe, a second refrigeration cycle circuit having a second compressor, a second radiator, a second pressure-reducing device and the supercooler that are connected through a refrigerant pipe, 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.

Description

technical field [0001] The present invention relates to a refrigeration device used for freezing or refrigerating food and the like. More specifically, it relates to a refrigeration device capable of supplying hot water while cooling. Background technique [0002] Currently, as such a refrigeration device, a refrigeration device using a vapor compression refrigeration cycle, which is composed of a compressor, a radiator, a pressure reducer, and an evaporator, and uses Freon gas or the like as a refrigerant, is widely used. That is, freezing and refrigeration are performed by cooling food and the like by evaporating the refrigerant in the evaporator of the vapor compression refrigeration cycle device. However, in generally widely utilized refrigeration devices, cooling waste heat from a refrigeration cycle is discarded from a radiator to the atmosphere or the like. On the other hand, the hot water used in the same facility is supplied by a boiler or the like using another h...
