Troubleshooting for blockage in the refrigeration system of Dongguan water chiller:
Replace the desiccant or drying filter, which is suitable for mild ice blockage.
For large devices, remove the original dryer in the system and temporarily install a large dryer to absorb moisture.
3. The system can be vacuumed, water vaporized at low pressure, and then discharged by a northern vacuum pump. However, the effect of this method is not obvious, especially when there is too much water. Practice has proven that once water is stored in the system, it is very difficult to use a vacuum pump to empty the system and completely vaporize it out of the system. The entire system or individual components should be heated and dried while vacuuming to completely remove moisture, but the operation is cumbersome. Generally, the method of cleaning or replacing the filter screen is used to eliminate the dirt blockage fault. If it cannot be eliminated at one time, it can be carried out multiple times until the dirty blockage is eliminated.
