Abstract: An air conditioning, heat pump and water heating system includes a compressor, a switching valve, an outdoor heat exchanger, a refrigerant storage tank, an indoor heat exchanger and a water heater. The air conditioning, heat pump and water heating system is configured to selectively operate between an air conditioning mode, a heat pump mode, a first water heating mode and a second water heating mode. In the first water heating mode, heat absorbed from an indoor space is utilized to heat up water circulating in the water heater so that when the air conditioning, heat pump and water heating system is operated in the first water heating mode, no heat is discharged to ambient environment. In the second water heating mode, heat absorbed from an ambient environment is utilized to heat up water circulating in the water heater.

Abstract: A refrigeration cycle apparatus simultaneously performs a cooling operation mode in which a refrigerant from a compressor is caused to flow to an indoor heat exchanger of an indoor unit having a cooling load, and a hot water supply operation mode in which a refrigerant from the compressor is caused to flow to a water heat exchanger of a hot water supply unit having a hot water supply demand. An operation control part switches the control mode of the simultaneous cooling and heating and hot water supply operation mode between a cooling-prioritized mode and a hot-water-supply-prioritized mode according to the relationship between the cooling load and the hot water supply load.

Abstract: A refrigeration cycle system is capable of reducing an amount of information required to be specified in advance, reducing a computational processing load, reflecting differences in actual installation conditions, and speeding up stabilization of an operational state in which the total amount of required input energy is reduced. A refrigeration cycle system is provided with a plurality of actuators, including outdoor fan motors, compressors, indoor fan motors, and the like for causing a refrigerant circuit to carry out a refrigeration cycle. A control unit obtains the slope at the current evaporation temperature and/or the current condensing temperature on a graph of the function between the actuators and the evaporation temperature or the condensing temperature, and updates the value of the target evaporation temperature and/or the target condensing temperature so that the sum of the input energy to the actuators is less that the current level.
