Abstract

A refrigeration cycle apparatus includes low-pressure side pressure detecting means for detecting the pressure of a refrigerant being sucked by a compressor, suction refrigerant temperature detecting means for detecting the temperature of the refrigerant being sucked by the compressor, frequency detecting means for detecting the operation frequency of the compressor, cooling target fluid inflow temperature detecting means for detecting the temperature of a cooling target fluid flowing in an evaporator, cooling target fluid outflow temperature detecting means for detecting the temperature of the cooling target fluid flowing out of the evaporator, and flow rate calculating means (measuring unit, computing unit, and storage unit) for calculating the absolute quantity of the flow rate of the cooling target fluid flowing in the evaporator using a value detected by each detecting means.
