Abstract

An air conditioner (1) having a refrigerant circuit including a compressor (16), a four-way valve (18), outdoor heat exchangers (19, 19A, 19B) and indoor heat exchangers (21A, 21B, 21C) which are successively connected to one another through a refrigerant pipe (14) including a receiver tank (71) connected to the outdoor heat exchangers in parallel, and a refrigerant bypass circuit (101) for making a part of refrigerant to the suction side of the compressor through the receiver tank while bypassing the outdoor heat exchangers under heating operation.
