Abstract
A machine includes at least two compressors that is controlled by a compressor controlling apparatus. By using an inverter for the at least two compressors, the use of elements is minimized and the compressor capacity may be increased, and the operation efficiency of the system may be enhanced. As an example, a plurality of operation modes may be used according to a load or cooling capacity of the two compressors. The two compressors are separately or simultaneously operated by using the inverter, thus simplifying the configuration of the system, and reducing cost.
