Abstract (en)
The present invention has an object to perform an operation with a high degree of freedom in each of an indoor unit (3A,3B,3C) and a water temperature regulation apparatus (40) and perform an efficient operation in accordance with operation states of the indoor unit and the water temperature regulation apparatus. In a mode in which indoor air conditioning by the indoor unit is prioritized, in the case where a target pressure of a refrigerant circuit of an outdoor unit (2) is set in accordance with a set temperature of each indoor unit, a water temperature regulation controller controls the degree of opening of an expansion valve (52) such that the capability of a water heat exchanger does not become equal to or more than 100%. Moreover, in the case where sufficient control cannot be performed by only adjusting the degree of opening of the expansion valve, the amount of water passing through a bypass (72) is adjusted by a water control valve (73), whereby the capability of the water heat exchanger of a water temperature regulation unit can be suppressed to be less than 100%.
