Abstract
A combined air-conditioning and hot-water supply system that, if a temperature that is set in a hot-water supply unit is higher than a temperature of refrigerant discharged from a compressor when the combined air-conditioning and hot-water supply system is in a heating operation cycle state, increases a target condensing temperature of an outdoor unit above the target condensing temperature that has been set, and controls an opening degree of an indoor expansion device to be less than the opening degree that has been set, such that a heating load of an indoor unit is maintained constant.
