Abstract
A capacity-variable air conditioner is capable of controlling capacity and consumed electricity in response to operation mode. The refrigerant compression quantity of a compressor is variably adjusted by control of open/close operation modes via selective combination of open/close valves of bypass pipes and bypass valve of the compressor in response to the operation mode. The capacity-variable air conditioner discharges some of the refrigerant infused into the compressor while the bypass valve of the compressor is opened under energy saving operation mode, such that refrigerant circulation quantity can be adjustably reduced under the energy saving operation mode where load of the compressor is less than that of a normal operation mode, thereby enabling a reduction in the capacity and consumed electricity.
