COMBINED SYSTEM OF AIR CONDITIONING DEVICE AND HOT-WATER SUPPLY DEVICE

摘要

A configuration provided with a heat source unit A, an indoor unit B, a circuit D for a hot-water supply heat source provided with a refrigerant - refrigerant heat exchanger 41 and throttle means 119 for the hot-water supply heat source, and a branch unit C that distributes a refrigerant flowing through the indoor unit and the circuit for hot-water supply heat source and also provided with a refrigerating cycle for air conditioning in which the indoor unit and the circuit for hot-water supply heat source are connected in parallel and connected to the heat source unit by at least two connection pipelines 106 and 107 via the branch unit and a refrigerating cycle for hot-water supply in which a compressor for hot-water supply, a heat-medium - refrigerant heat exchanger, throttle means for hot-water supply, and the refrigerant - refrigerant heat exchanger are connected in series, in which the refrigerating cycle for air conditioning and the refrigerating cycle for hot-water supply are connected so as to exchange heat between the refrigerant for air conditioning and the refrigerant for hot-water supply in the refrigerant - refrigerant heat exchanger.
