Abstract
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 and throttle 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 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 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.
