Evaporator maintenance precautions

The internal leakage of the freezer refrigerator evaporator is a common fault, and the method of replacing the evaporator is generally adopted in the maintenance. Since there are no ready-made evaporators for sale on the market, most of them are repaired by hand-made evaporators. However, after the replacement of the hand-made evaporator, the cooling capacity is prone to decrease. Originally, the cooling capacity of the empty machine (loaded) could reach -18°C for half an hour, but it could only reach about -10°C after maintenance, and the cooling capacity was greatly reduced.

After replacing the evaporator, the amount of refrigerant used may be different from the original one. The judgment method at this time is that the return pipe outside the box is not condensed. The main reason for replacing the evaporator in the refrigerator is that there are many failures in the evaporator in the refrigerator. When the failure occurs, it will affect the refrigeration effect of the refrigerator. The refrigerator replacement evaporator needs to be installed and replaced according to the specific failure.
