開始制御装置。 A method for starting defrosting of the evaporator 5 in a refrigeration system that includes an evaporator 5 and an evaporator fan 10 installed on one side of the evaporator 5, and performs cooling operation with air passing through the evaporator 5. The control device is provided with a first command means for issuing a defrost start command at regular intervals based on the timing of a defrost timer TM, and has a winding of the fan motor MF1 that drives the fan 10. A temperature detector 11 for detecting temperature is provided,
A second command means for asynchronously issuing a defrost start command based on the temperature detected by the detector 11 is provided, and a reset means is provided for resetting the defrost timer TM with an output from the second command means. Defrost start control device for refrigeration equipment.
