AIR-CONDITIONING HOT-WATER SUPPLY COMBINED SYSTEM

摘要

Provided is an air-conditioning hot-water supply combined system configured such that, in the case where all of load side units perform a cooling operation and a hot water load (heating load) is low during a cooling and heating mixed operation in a cooling cycle, an input of an air conditioning refrigerant block is reduced to increase the COP of the system. An air-conditioning hot-water supply combined system A reduces a target condensing temperature in a heat source unit 10 in the case where a heating load in load side units 30 and a hot water load in a hot water unit 40 are less than a predetermined reference value in a cooling operation cycle state.
