PROBLEM TO BE SOLVED: To obtain a refrigerating cycle capable of being formed by one throttle device in which the increase of pressure loss by an accumulator is prevented and one of the throttle devices can be formed by one capillary tube, since the inlet and outlet of a receiver are not reversed in a cooling operation and a heating operation. SOLUTION: A refrigerant circuit of an air conditioner comprises a compressor, a four-way valve connected to the compressor through a pipe, an outdoor heat exchanger connected to the four-way valve through a pipe, an indoor heat exchanger connected to the four-way valve through a pipe, a bridge circuit composed of four check valves and having one side connected to the outdoor heat exchanger and the other side connected to the indoor heat exchanger respectively through pipes, and a receiver connected to the bridge circuit through two pipes to store excess refrigerant generated during circulation. The first throttle device is provided in piping for connecting the inlet side of the receiver to the bridge circuit, and the second throttle device is provided in piping for connecting the outlet side of the receiver to the bridge circuit.
