PROBLEM TO BE SOLVED: To eliminate shortage of circulating amount of refrigerant and assure a capacity of refrigerant even if a pressure of refrigerant at a discharging side of a compressor is decreased by correcting operation capacity of the compressor on the basis of suction side pressure thereof under a condition in which a refrigerant condensing temperature is not higher than a predetermined value. SOLUTION: Means 102 for correcting and operation capacity of a compressor constituting an outdoor control section 50 uniformizes a content of each of satisfaction level commands receive from each of indoor devices Y and in correspondence with this operation, operation capacity of the compressor is corrected. A correction signal is added to an invertor 52 through an adding means 104, and if a mean value of contents of the satisfaction level commands, for example, is excessive, the operation capacity of the compressor 1 is decreased only by a predetermined value and in turn, if the mean value of the contents of the satisfaction level commands is deficient, the operation capacity of the compressor 1 is increased only by a predetermined value. Accordingly, even in the case that a refrigerant pressure at the discharging side of the compressor is decreased, it is possible to eliminate shortage of circulating amount of refrigerant and assure a capacity of the refrigerant.
