A refrigeration cycle device includes a heat pump cycle, a high-temperature heat medium circuit, and a low-temperature heat medium circuit. The low-temperature heat medium circuit includes a plurality of heat absorption devices configured to have a heat absorption amount to be absorbed by the low-temperature heat medium flowing out of a low-temperature heat medium-refrigerant heat exchanger, and a heat absorption adjusting unit configured to change the heat absorption amount of the low-temperature heat medium in the respective heat absorption devices. In the refrigeration cycle device, a flow amount of the refrigerant flowing into the low-temperature heat medium-refrigerant heat exchanger is reduced when the heat absorption adjusting unit changes the heat absorption amount of the low-temperature heat medium in the respective heat absorption devices, and the flow amount of the refrigerant flowing into the low-temperature heat medium-refrigerant heat exchanger is increased when a recovery condition is satisfied.
