To provide a refrigeration cycle for condenser capable of reusing waste heat, whereas the waste heat is disposed in conventional water-cooled and air-cooled methods for cooling a refrigerant for refrigeration cycle to liquid.

The waste heat is heat-exchanged with water in a container, whereby hot water of high temperature is obtained. A refrigerant which is condensed at a temperature lower than a refrigerant conventionally used by recovering the waste heat and heat-exchanging the residual heat from an evaporator in the container bottom can be used. Further, an outdoor unit and an indoor unit which were set in distant places can be integrated together by radiating the heat as hot water. If hot water is not needed, it may be released as steam by a fan motor provided at an upper portion of the container.
