APPARATUS PROTECTION DEVICE AND APPARATUS PROTECTION METHOD

WIPO Patent Application WO/2019/021469

A1

Provided is an apparatus protection device comprising: a first sensor for detecting the temperature of a refrigerant used in the cooling of an apparatus that includes a heating element; a second sensor for detecting the temperature of the apparatus; and a controller 10 for applying a drive restriction to the apparatus on the basis of a first detected temperature detected by the first sensor, and a second detected temperature detected by the second sensor. The controller 10 calculates the temperature difference between the first detected temperature and the second detected temperature, and if the temperature difference is higher than a prescribed temperature difference threshold, the controller 10 applies a drive restriction to the apparatus, and if the second detected temperature is higher than a prescribed first temperature threshold, the controller 10 applies a drive restriction to the apparatus.
