What is the reason for the poor cooling effect in the cold storage installation project?
In the process of using cold storage, there is often a bad cooling effect, so what is the reason for this situation?
Lack of refrigeration capacity
If the refrigerant dose in the system is insufficient, it will cause a certain influence on the refrigerant flow rate of the evaporator. When the expansion valve is opened relatively, or because the expansion valve is not adjusted properly, the refrigerant flow deviation will occur. Large phenomena will also affect the cooling effect of the cold storage project. At the same time, if the expansion valve is opened to a small extent or there is a blockage, the refrigerant flow will be reduced. These reasons often lead to the cold storage project. In the case of poor cooling performance, we must observe the evaporation pressure in time, and judge by evaporating pressure and evaporating temperature, so that the refrigerant flow suitable for the expansion valve can be determined, and the occurrence of plugging of the expansion valve often leads to The refrigerant flow rate of the cold storage project has a certain influence. The refrigerant itself contains a certain amount of water. When the refrigerant flows through the expansion valve, the temperature must be reduced to below zero, and the moisture of the refrigerant will also form at this time. Ice, then it may cause the expansion valve to block, it will also lead to cold storage engineering The cooling effect is not good phenomenon.
Refrigerant flow is too large
If there is a lot of frozen oil in the heat transfer tube of the evaporator, it will also cause more air in the infecting tube. At this time, the heat exchange area of ​​the evaporator will be reduced, resulting in poor cooling performance in the cold storage project. A phenomenon, at this time will also lead to an effective reduction in the speed of the cold storage temperature drop, in the daily use process, we must promptly remove the oil contamination phenomenon in the evaporator heat transfer tube in time, so that the cold storage project can be made Reduce the phenomenon of poor cooling.
Reduced heat transfer
The heat transfer effect is reduced, mainly because a lot of dust accumulates on the outside of the evaporator, which will lead to a phenomenon of poor cooling performance in the cold storage project. The main reason for the temperature drop in the cold storage is also because the heat transfer efficiency of the evaporator is The decline is caused by, at the same time, it may be caused by the relatively high humidity in the warehouse. Therefore, we must perform defrosting frequently in our daily life. We can often use it in the process of cold storage project. When the cold storage door is opened, the temperature of the cold storage will rise at this time. After the frosting phenomenon is dissolved, and then the compressor is started again, this method can reduce the poor cooling performance of the cold storage project.
