Zusammenfassung:	PURPOSE:To prevent the sound of refrigerant during heating operation and stopped state in an indoor device in which the refrigerant flows into an indoor heat exchanger even in case of the stopped state of the heating operation in the same manner as that of the heating operation. CONSTITUTION:A plurality of indoor devices 3a to 3c having indoor heat exchangers 13a to 13c and electric expansion valves 14a to 14c stored therein are connected in parallel with one outdoor device 2 having compressors 4 and 5 and an outdoor heat exchanger 7 stored therein and at the same time capillary tubes 16a to 16c are arranged in parallel with the expansion valves 14a to 14c and further resistance values of these capillary tubes are set to be smaller than a resistance value of a degree of opening of each of the expansion valves during stopped state of the heating operation.
