    • PROBLEM TO BE SOLVED: To accurately determine a refrigerant quantity filled with a refrigerant circuit, when filling a refrigerant in the refrigerant circuit, in an air conditioner having a plurality of heat source units. SOLUTION: This air conditioner 100 has a first outdoor unit 1a including a first outdoor heat exchanger 4a and a first outdoor expansion valve 3a adjusting a first supercooling degree on the outlet side of the first outdoor heat exchanger 4a, a second outdoor unit 1b including a second outdoor heat exchanger 4b and a second outdoor expansion valve 3b adjusting a second supercooling degree on the outlet side of the second outdoor heat exchanger 4b, a first outdoor side determining part 62a determining the first supercooling degree, a second outdoor side determining part 62b determining the second supercooling degree, a first outdoor side opening adjusting part 64a and a second outdoor side opening adjusting part 64b. The first outdoor side opening adjusting part 64a and the second outdoor side opening adjusting part 64b respectively control the first outdoor expansion valve 3a and the second outdoor expansion valve 3b so as to reduce a difference between the first supercooling degree and the second supercooling degree when the refrigerant is filled in the refrigerant circuit having the first outdoor heat exchanger 4a and the second outdoor heat exchanger 4b.

    • PROBLEM TO BE SOLVED: To prevent comfortability from being impaired by securing air-conditioning capacity to the maximum within the limit according to a user's demand, that is, the limit of power consumption. SOLUTION: In this air conditioner, an outdoor unit 13 having a plurality of compressors 1, 2, a four-way valve 3, heat source side heat exchangers 4, outdoor expanders 5 and outdoor blowers 8, and a plurality of indoor units 12 having motor expansion valves 9, use side heat exchangers 10 and indoor blowers 11, are connected with liquid connection piping 14 and gas connection piping 15. An upper limit of power consumption is set beforehand, and the operation frequency of at least one of the plurality of compressors is reduced by a predetermined control range when an operating current of the air conditioner is larger than a current value based on the upper limit. The operating number of the other compressors is reduced when an operating current of the air conditioner is larger than the current value based on the upper limit of power consumption even if the frequency becomes a lower limit of the operation frequency.
