Ice blocking of the temp - humi chamber

　　

1. After the refrigeration evaporator is broken, the water molecules in the freezing (hiding) chamber and the water vapor in the air will be brought into the compressor when the refrigeration evaporator is broken. Water molecules in the air are brought into the machine).

　　

2. When the low-temperature equipment compressor is pressurized and leaks, the water vapor in the air is compressed into water and injected into the pipeline to cause ice blockage.

　　

3. If the refrigerant has too much moisture, charging will cause ice blockage.

　　

　　4. The process tube of the high and low temperature machine was not sealed after being opened and was not repaired in time. This long-term shelving of frost, coupled with occasional turning on, will bring moisture in the air into the machine from outside the nozzle. There are also unsealed compressors that have been stored for a long period of time. If they are replaced with frost and used without drying, they will also cause ice blockage.

5. The filter drier is aging and invalid, losing its proper function of drying and water absorption. Among the above 5 items, 1 and 2 are the most prominent.
