Refrigeration cycle device

摘要

In a refrigeration cycle device (2) in which heat generated by heat absorption of an evaporator (16) is used for heating in a condenser (11), a disadvantage that a cooling capacity of the evaporator (16) deteriorates owing to shortage or drop of an amount of the heat to be rejected from the condenser (11) is securely avoided and a cooling function is maintained. In the refrigeration cycle device which is provided with a refrigerant circuit including a compressor (10), a condenser (11), an expansion valve (14) and an evaporator (16) and which exhibits a heating function by the heat rejected from the condenser (11) and which exhibits the cooling function by the heat absorption of the evaporator (16), an operation to secure a predetermined amount of the heat to be rejected from the condenser (11) is executed in order to maintain the cooling function of the evaporator (16) based on an index capable of grasping the amount of the heat to be rejected from the condenser (11).
