PROBLEM TO BE SOLVED: To provide an air conditioner which performs operation of a high performance coefficient (a high energy saving property) throughout the year by improving efficiency in response to an actual condition of a use environment. SOLUTION: This air conditioner includes a refrigeration cycle structured by sequentially connecting a compressor 1, a heat source side heat exchanger 3, a first pressure reducing device 4, a receiver 5, a second pressure reducing device 7a, and a use side heat exchanger 8 by a pipe, and is provided with injection circuits 111, 112 connected to a compression chamber of the compressor 1 from the receiver 5, and a bypass circuit 110 connected to an inlet side pipe 109 of the compressor 1 from the injection circuits.
