How to deal with the blockage failure of the cold storage refrigeration system

In the process of using cold storage refrigeration equipment, it is difficult to buy faults in the refrigeration system, such as ice gambling and blockage. How to solve the blockage of the refrigeration system?

Replace the desiccant or dry filter, this applies to a light ice block.

For large installations, remove the original dryer from the system and temporarily install a large dryer to absorb moisture.

The system can be evacuated, the water vaporized at a low pressure, and then the North Vacuum Pump removes the system. However, the effect of this method is not obvious, especially when there is too much water. Practice has proved that once the system stores water, it is very difficult to evacuate the system with a vacuum pump to vaporize it completely out of the system. The whole system or various components should be heated and dried, and vacuumed while drying, the water can be completely removed, but the operation is troublesome.

For cold storage dirty plugging, it is generally excluded by cleaning or replacing the filter. If it cannot be excluded at one time, it can be performed multiple times until the dirty block is removed.
