REFRIGERATION AND FREEZING DEVICE AND EVAPORATOR DEFROSTING CONTROL DEVICE THEREOF

WIPO Patent Application WO/2021/218369

A1

A refrigeration and freezing device and an evaporator defrosting control device thereof. The defrosting control device comprises a ceramic sensor, a heating device and a controller, wherein the ceramic sensor is arranged on an evaporator and is used for measuring the amount of frosting of the evaporator; the heating device is arranged on the evaporator; and the controller is electrically connected to the ceramic sensor and the heating device, and is configured to start the heating device when the ceramic sensor detects that the amount of frosting of the evaporator is greater than a first preset amount of frosting. According to the refrigeration and freezing device and the evaporator defrosting control device thereof, by means of arranging the ceramic sensor on the evaporator, the amount of frosting of the evaporator can be directly measured, and whether the evaporator meets a defrosting condition is directly determined according to the amount of frosting of the evaporator, thereby accurately determining the starting and stopping of defrosting of the evaporator, and reducing the energy consumption.
