Title:
REFRIGERATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2012/002248
Kind Code:
A1
Abstract:
Provided is a refrigeration apparatus wherein hot water can be supplied by effectively using waste heat generated when a food or the like is cooled, and the cooling capacity and the cooling efficiency can be improved. A supercooling device (5) for supercooling refrigerant introduced from the intermediate receiver (14) to the second decompressor (13) is provided in a first refrigeration cycle circuit (91) provided with a first decompressor (3), an intermediate pressure receiver (14), and a second decompressor (13), wherein refrigerant within the intermediate pressure receiver (14) is introduced to a first compressor (1) during a compression process. The refrigerant in the first refrigeration cycle circuit (91) is supercooled by the evaporation of refrigerant in a second refrigeration cycle circuit (92) in the supercooling device (5), and water to be supplied is heated by a heat release action of the refrigerant in a second heat release device (32) of the second refrigeration cycle circuit (92). The refrigerant in the first refrigeration cycle circuit (91) is supercooled by the second refrigeration cycle circuit (92), and accordingly, the cooling capacity and the cooling efficiency of the first refrigeration cycle can be improved, and hot water can be supplied by effectively using waste heat generated when the refrigerant is supercooled.
