。[Scope of Claim for Utility Model Registration] A refrigerant flow rate control device for a refrigeration system for controlling the internal temperature of the refrigeration system, including a refrigeration cycle that controls the refrigerant flow rate using an electric valve, and a sensor that detects the temperature of each part of the refrigeration cycle. a device that performs superheat degree control and temperature control according to the detection output of this sensor; and a timer that sets a time when the refrigeration cycle should operate and a time when it should stop operating, and repeatedly outputs an output for each of these times. According to the output of this timer, both of the control operations are performed during the time when the operation should be performed, and the electric valve is fully closed during the time when the operation should not be performed, so that the temperature inside the refrigerator is above a predetermined temperature. A refrigerant flow control device for a refrigeration system equipped with a control device that does not close an electric valve.
