Simple analysis of common phenomena in cold storage:
1. The cold storage has a large loss of cold capacity due to poor heat insulation or sealing performance
2. The surface of the evaporator has too thick frost or too much dust, and the heat transfer effect is reduced
3. There is more air or refrigerated oil in the evaporator, and the heat transfer effect is reduced
4. The throttle valve is improperly adjusted or blocked, and the refrigerant flow is too large or too small
5. Insufficient amount of refrigerant in the system and insufficient refrigeration capacity
6. The compressor has low efficiency and the cooling capacity cannot meet the load requirements of the warehouse
