The freezing or deterioration of items in the cold storage may be caused by the following reasons:

Possible reasons:
- Improper temperature setting: too high or too low, not meeting storage requirements.
- Poor air circulation: uneven distribution of cold air and abnormal local temperature.
- Unreasonable placement of items: The goods are stacked too densely, hindering the circulation of air conditioning.
Solution:
- Accurate temperature setting: Set the appropriate temperature based on the characteristics of the item.
- Optimize air circulation: Check the fan and ventilation openings to ensure air circulation.
- Scientific classification and placement: Reasonably place goods and reserve ventilation gaps.
