Title:
AIR CONDITIONING AND HOT WATER SUPPLYING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/185689
Kind Code:
A1
Abstract:
This air conditioning and hot water supplying system comprises a first refrigeration cycle comprising a compressor for hot water supply, a heat exchanger for hot water supply, and a cascade heat exchanger, and a second refrigeration cycle comprising a compressor for air conditioning, an outdoor heat exchanger, an indoor heat exchanger, and the cascade heat exchanger. The amount of refrigerant for hot water supply enclosed in the first refrigeration cycle is an amount such that the saturated liquid pressure of a mixed refrigerant, when the refrigerant for hot water supply is mixed into the refrigerant for air conditioning, is no greater than the maximum working pressure of the compressor for air conditioning. Thus, the reliability of the second refrigeration cycle can be improved without compromising compressor durability.
