霜装置。 A defrosting control means includes an electric heater that is energized during heating operation and defrosting operation, and has a defrosting timer and an evaporator outlet refrigerant temperature detector that control energization to the electric heater, and an abnormality caused by the electric heater. In a refrigeration system equipped with an overheat prevention temperature detector for preventing overheating, and further comprising a return air temperature detector, a supply air temperature detector, and a residual frost/ice detector, the overheat prevention temperature detector,
A return air temperature sensor, a supply air temperature sensor, and a residual frost/ice detector are connected to the defrosting control means, and defrosting is started when the temperature detected by either the evaporator outlet refrigerant temperature sensor or the overheating prevention temperature sensor is detected. In addition to the normal defrosting system that signals the end of defrosting, when the residual frost/ice detector detects residual frost/ice at the end of defrosting of this normal defrosting system, the defrosting end temperature is detected. A defrosting device for a refrigeration system, characterized in that it is equipped with a backup defrosting system that performs backup defrosting with correction.
