PROBLEM TO BE SOLVED: To provide a refrigeration cycle device, in particular an air-conditioner for reducing thermal loss that a four-way valve has by using the four-way valve and at the same time reducing a pressure loss in a refrigeration cycle. SOLUTION: An air-conditioner is provided with a refrigeration cycle where a compressor 10, an indoor heat exchanger 50, a throttling device 40, and an outdoor heat exchanger 30 are connected with piping via a four-way valve 20. In the air-conditioner, a bypass pipe 91A is provided in parallel with a refrigerant path for connecting the discharge port of the compressor 10 that is one of the refrigerant paths of the four-way valve 20 to the outdoor heat exchanger 30, a switching valve 91B is provided at the bypass pipe, the switching valve 91B is opened in cooling operation, and a refrigerant is allowed to flow to the bypass pipe 91A.
