PROBLEM TO BE SOLVED: To regulate the composition of the low boiling point components circulating in a refrigerant circuit, according to the length of a pipe, and suppress the drop of performance in the case where the pipe is long. SOLUTION: An air conditioner, where an outdoor unit 1 having at least a compressor 10 and an outdoor heat exchanger 12 and an indoor unit 2 having at least a throttle device 21 and an indoor heat exchanger 20 are connected with each other by pipe and a refrigerant circuit using a zeotropic refrigerant as a refrigerant is made, is equipped with an accumulator 15 which separates low boiling point components and high boiling point components out of the the zeotropic refrigerant circulating in that refrigerant circuit and regulates the composition of that tow boiling point components, being provided on the low pressure side of the refrigerant circuit.
