Fault analysis: the temperature of the cold storage room is high

The cold storage room is a place for refrigerating objects. The temperature is generally between 0 and 15 degrees, but it is also outside, but it will not exceed ten degrees, otherwise it will be broken. The general refrigerator is cooled by a heat pipe. It is transmitted, and the inside is cooled to reduce the heat. Sometimes, water is generated in the interior wall of the refrigerator, which is only caused by the large temperature difference between the inside and the outside.

This fault is reflected in the high temperature in the refrigerating compartment. Since the deli cabinet is a three-cycle deli cabinet, the three compartments can be separately controlled. The deli refrigerator compartment has a defrosting problem and will only stop when defrosting. Supply of cold air will cause the temperature to rise, and the normal defrosting stop condition is:

1. Stop the defrosting when the temperature of the temperature sensor head of the evaporator is raised to 6 degrees.

2, the longest defrosting time is 2 hours.

When there is ice around the temperature sensing head of the deli cabinet evaporator, the temperature of the temperature sensor head of the R evaporator is difficult to rise to 6 degrees, so there is no air supply within 2 hours. Causes the temperature of the refrigerator to rise.

The experience is summarized: the R evaporator temperature sensing head of the refrigerating room cannot be replaced by the refrigerating room temperature sensing head. Because the temperature of the deli cabinet evaporator is below -25 in actual working hours, the refrigerating room temperature sensing head cannot work at this low temperature. Do not change when changing the temperature sensor.

The process of repairing the cooked food cabinet should be in place, the water to be treated must be thoroughly cleaned, and the insulation should be sealed well, otherwise it will be repaired more and more bad.
