A refrigeration cycle apparatus 100 includes a volume control compressor 101, a volume control path 111, a four-way valve 112 (flow path switching unit), a high-pressure introduction path 114, a low-pressure introduction path 116, and a check valve 120. When the load is small, the four-way valve 112 is controlled so as to connect the volume control path 111 to the low-pressure introduction path 116. When the load is large, the four-way valve 112 is controlled so as to connect the volume control path 111 to the high-pressure introduction path 114. The high-pressure introduction path 114 is provided with the check valve 120 that permits a flow of a refrigerant in a direction from the flow path 10a to the four-way valve 112 and that precludes a flow in the opposite direction. |
