Abstract
Disclosed are an air conditioning system with two compressors so as to shorten standby time for re-operating a stopped compressor and variably change the compression capacity of a refrigerant according to cooling load, and a method for operating the air conditioning system. The method for operating the air conditioning system with two compressors, comprises the first step of simultaneously operating the compressors regardless of cooling load at an early stage of the operation, the second step of selectively operating one of the compressors according to the cooling load, and the third step of additionally re-operating the stopped compressor when the operated compressor selected from the compressor in the second step is continuously operated for longer than a designated time, thereby shortening the standby time for re-operating the stopped compressor, rapidly changing the compression capacity of the refrigerant according to the cooling load, and improving users' comfort within a room.
