Abstract:
1. An air conditioner comprising: a plurality of compressors; discharge pipes to discharge a fluid compressed in the plurality of compressor; oil separators connected to the discharge pipes to separate oil from the fluid; oil recycle pipes to introduce the oil to the plurality of compressors; an intake passageway configured to distribute the fluid to each of the compressors; a bypass unit to guide the fluid from the plurality of compressors to the intake passageway, the bypass unit including: an expansion valve disposed between the common bypass pipe and the intake passageway to control a flow rate of fluid from the common bypass pipe to the intake passageway; a memory to store information of a reference refrigerant temperature range R a control part configured to control the operation of the expansion valve, based upon result of comparison of the temperature sensed at the temperature sensors with at least one of the R
