After the hotel cold storage is installed , the cooling effect of the cold storage is not particularly satisfactory. There are problems such as slow cooling of the cold storage and excessive consumption of cold storage. Therefore, these problems need to be resolved in a timely manner. Come down to our hotel cold storage installation, let's analyze with you what are the factors that cause the cold storage refrigeration effect to become worse.
1. Too much frost on the surface of the evaporator leads to poor heat transfer efficiency and slower temperature drop in the cold storage. In most cold storage evaporators, the surface temperature is below 0 degrees Celsius, and the humidity in the warehouse is relatively high. The moisture in the air is likely to frost and even freeze on the surface of the evaporator, which affects the heat transfer effect of the evaporator. . To prevent the thick frost layer on the surface of the evaporator, it should be defrosted regularly.
2. There is more air or refrigeration oil in the evaporator, which will also reduce the heat transfer effect of the cold storage. If there is too much refrigeration oil on the inner surface of the heat transfer tube of the evaporator, its heat transfer coefficient will decrease. Similarly, if there is more air in the heat transfer tube, the heat transfer area of the evaporator will be reduced and its heat transfer efficiency will be reduced. It will also drop significantly, and the temperature drop in the warehouse will slow down. Therefore, the air and refrigeration oil in the cold room need to be cleaned regularly.
3. The lack of refrigerant in the cold storage leads to insufficient cooling capacity. There are two main reasons for the lack of refrigerant: First, the refrigerant charge is insufficient. At this time, you only need to add a sufficient amount of refrigerant. Another reason is that the system has a lot of refrigerant leakage. In this case, you should first find the leak point, focus on the inspection of the pipeline and valve connections, repair the leaked parts, and replenish the refrigerant in a timely manner.
