摘要： An excessive increase in high pressure during a high-temperature-water supply is suppressed and a predetermined hot-water-supply capacity within a usage range of a compressor is ensured in a refrigeration cycle apparatus that can perform the hot-water-supply operation of an integrated air-conditioning and hot-water-supply system. An integrated air-conditioning and hot-water-supply system 100 includes a compressor 1, a plate-type water heat exchanger 16, a hot-water-supply pressure-reducing mechanism 19, and an outdoor heat exchanger 3. Moreover, the integrated air-conditioning and hot-water-supply system 100 includes a high-pressure sensor 201 that detects a high pressure in the compressor 1, and a controller 110 that calculates a condensing temperature of the plate-type water heat exchanger 16 based on the high pressure detected by the high-pressure sensor 201. When the calculated condensing temperature is higher than or equal to a preset target condensing-temperature value, the controller 110 performs condensing-temperature control for controlling the operating frequency of the compressor 1 based on a difference between the calculated condensing temperature and the target condensing-temperature value, and performs opening-degree control for controlling the opening degree of the hot-water-supply pressure-reducing mechanism 19 concurrently with the condensing-temperature control based on a difference between a current opening degree of the hot-water-supply pressure-reducing mechanism 19 and a preset target opening-degree value.

As control modes of the simultaneous cooling and hot water supply operation mode, a cooling-prioritized mode in which the operation frequency of the compressor 1 is controlled according to the cooling load, and a hot-water-supply-prioritized mode in which the operation frequency of the compressor 1 is controlled according to the hot water supply demand, are provided. An operation control part 103 switches the control mode of the simultaneous cooling and heating and hot water supply operation mode between the cooling-prioritized mode and the hot-water-supply-prioritized mode according to the relationship between the cooling load and the hot water supply load.

摘要： A combined air-conditioning and hot water supply system for simultaneously executing a cooling operation and a hot water supply operation is provided, in which the operation of a compressor is controlled to complete hot water supply with high efficiency and in a short time to thereby prevent running out of hot water. In a case where a combined air-conditioning and hot water supply system 100 simultaneously executes the cooling operation of a use unit 303 and the hot water supply operation of a hot water supply unit 304, the combined air-conditioning and hot water supply system 100 operates in a cooling priority mode when the temperature differential ”T wm between a set hot water supply temperature T wset and the inlet water temperature T wi of a plate water-heat exchanger 16 is smaller than a priority operation determination threshold M that is set in advance, and operates in a hot water supply priority mode when the temperature differential ”T wm becomes equal to or higher than the priority operation determination threshold M. In the cooling priority mode, the operating frequency of a compressor 1 is controlled in accordance with the temperature differential between the suction air temperature of the use unit 303 and the indoor set temperature of the use unit 303. In the hot water supply priority mode, the operating frequency of the compressor 1 is controlled in accordance with the temperature differential between the set hot water supply temperature T wset and the water temperature in a hot water supply tank 305.
