Abstract
A method for controlling operations of an air-conditioner includes: a step in which when an operation load of an air-conditioner increases, if an outputted compressing capacity of the air-conditioner is smaller than a compressing capacity corresponding to the operation load and an operation frequency of the first compressor is a maximum frequency of the first compressor, a second compressor is operated; and a step in which when the operation load is reduced, if the outputted compressing capacity of the air-conditioner is greater than the compressing capacity corresponding to the operation load and the operation frequency of the first compressor is a minimum frequency of the first compressor, the second compressor is stopped.
