Reasons for the frosting of the compressor of the high and low tempera

Reasons for the frosting of the compressor of the high and low temperature alternating damp heat test chamber

   Occasionally, some customers report that the compressor of the high and low temperature alternating damp and heat test chamber will be frosted and frozen. In fact, this is not an equipment problem, as long as we pay attention to maintenance work, it can be avoided!

   1. After the technical tube of the high and low temperature alternating damp heat test chamber was opened, it was not sealed or repaired in time. There is also a type of compressor that has been left for a long time and is prone to frost when it is used without drying.

   2. The refrigeration evaporator may be damaged. In addition, after a long time start, the water molecules in the freezer compartment will be carried into the compressor together with the water vapor in the air.

   3. When the evaporator is poorly ventilated, if the cold is not taken away, it will also cause frosting and freezing, and the compressor pressure will be too low, resulting in frosting of the compressor shell.

   4. When the test chamber is in normal working condition, the compressor sucks back refrigerant vapor instead of liquid. If there is too much refrigerant and refrigerating oil in the refrigeration system, or the flow rate adjusted by the expansion valve is too large, frosting will also occur.

   5. In the case of aging failure, the filter drier loses its drying and water absorption capacity. The inability to absorb water vapor inside the compressor can also cause frost.

   The above points may cause frosting in the compressor of the high and low temperature alternating damp heat test chamber, so users should pay more attention to these problems when using them, and do a good job of maintenance and repair.
