Abstract (en)
[origin: EP2884205A1] An air conditioning apparatus (1) is provided with a refrigerant circuit (10) further provided with a compressor (21), an outdoor heat exchanger (23), an indoor heat exchanger (42a, 42b), and a stored-heat heat exchanger (28) that exchanges heat between a refrigerant and a heat storage material, and is capable of performing a heat storage operation during a heating operation and a stored-heat usage operation during a defrosting operation. The refrigerant circuit (10) is further provided with a heat storage valve (29) for varying the quantity of refrigerant flowing into the stored-heat heat exchanger (28). With this air conditioning apparatus (1), in the heat storage operation, the opening degree of the heat storage expansion valve (29) is controlled so as to be the setting heat storage operation opening degree determined according to a function based on the condensation pressure of the refrigerant, the liquid pipe pressure in the outlet and inlet of the heat storage expansion valve (29), and the enthalpy of refrigerant at the outlet and inlet of the stored-heat heat exchanger (28).
