HEAT-GENERATING UNIT

摘要

A heat-generating unit includes a hot-water-supply compressor that compresses a hot-water-supply refrigerant; a hot-water-supply heat exchanger that exchanges heat between the hot-water-supply refrigerant and a hot-water-supply heat medium; a cascade heat exchanger that exchanges heat between the hot-water-supply refrigerant and an air-conditioning refrigerant; and a casing that houses the hot-water-supply compressor, the hot-water-supply heat exchanger, and the cascade heat exchanger. The hot-water-supply heat exchanger is disposed on a bottom plate member of the casing, and the hot-water-supply compressor and the cascade heat exchanger are disposed above the bottom plate member of the casing.
