1. Defrosting electric heater. The defrosting electric heater is inserted into the tube installed in the evaporator, is energized by the action of the defrosting thermostat, and heats the evaporator from the inside to quickly melt the frost.
2. Drain electric heater. The electric drain heater is installed in the sink next to the wall. Through the action of the defrosting thermostat, it will be energized during defrosting, so as to dissolve frost and prevent freezing.
3. Thermal compensation electric heater. The thermal compensation electric heater is installed in the main body of the temperature-sensing thermostat in the box. Due to the installation position of the thermostat and other reasons, if the temperature of the main body is lower than the temperature of the heat-sensitive part At this time, the thermostat will malfunction. Therefore, slightly heat the main body to keep the thermostat in normal operation. Recently, the thermostat has been improved and the thermal compensation electric heater is no longer used.
4. The outer box electric heater, the next wall electric heater, the outer box electric heater, and the next wall electric heater are respectively installed on the outer periphery of the outer box body and the middle partition wall. If the ambient temperature is quite high, the temperature in front of the outer box will be cooled to below the dew point temperature, the moisture in the air may sometimes condense and condense. Therefore, this electric heater is used to prevent this phenomenon. Some refrigerators are equipped with a hot gas pipe heated by the exhaust of the compressor to prevent condensation, so the outer box electric heater and the next wall electric heater are no longer used in some refrigerators.
