It is very common that the temperature inside the freezer glass door cannot be lowered or the temperature is lowered slowly. Then why can't the temperature of the glass door of the refrigerator drop? Let me analyze your reasons. I hope it helps you!
1. There is more air or refrigerant oil in the evaporator of the glass door of the refrigerator to reduce the heat transfer efficiency
Once more refrigerant oil is attached to the inside and outside of the heat transfer tube of the refrigerator glass door evaporator, the heat transfer coefficient will drop significantly.
Similarly, if there is more air in the heat transfer tube, the heat transfer area of the evaporator of the glass door of the supermarket refrigerator will be reduced, the heat transfer power will be significantly reduced, and the cooling rate of the cooling chamber will be reduced accordingly. Therefore, in daily operation and maintenance, attention should be paid to clearing the grease on the inside and outside of the heat exchange tube of the supermarket freezer evaporator in time, and to discharge the air in the supermarket freezer evaporator to improve the heat exchange efficiency. Evaporators for supermarket freezers.
2. The throttle valve is improperly adjusted or blocked, and the snow accumulation is too large or too small
If the throttle valve is improperly adjusted or blocked, it will directly affect the flow of snow into the transpirator of the supermarket freezer. If the throttle valve opening is too large, the refrigerant flow rate is too large, the transpiration pressure and transpiration temperature also increase, and the cooling chamber cooling speed slows down; at the same time, when the throttle valve opening is too small or blocked, the snow seed flow rate will also be reduced. The cooling capacity of the system will also be reduced, and the cooling chamber will cool down more slowly. Generally, we can judge whether the snow flow rate of the throttle valve is appropriate by observing the evaporation pressure, evaporation temperature and straw frosting.
