る冷凍機の制御装置。 A refrigeration cycle in which a compressor, a condenser, an expansion valve, and an evaporator are connected via refrigerant piping so that cooling operation by the evaporator and defrosting operation of the evaporator can be performed; A control device for a refrigerator that has a flow control valve that changes the flow rate of refrigerant, which operates based on a temperature detector that detects the temperature of a space in which an evaporator is installed, and a detected value and a set value of this temperature detector. a valve drive unit that sets the opening degree of the flow rate control valve based on the output of the proportional-integral operation unit, and a blower for the evaporator after a predetermined time delay from the start of cooling operation when defrosting operation is canceled. A defrosting operation control section that starts the operation of the fan, and a control section that masks the integral operation of the proportional integral operation section when the defrosting operation starts, and starts this integral operation when the blower starts operating. A control device for a refrigerator.
