What causes slow cooling of air-cooled cold storage?

　　Air-cooled cold storage, as a common cold storage equipment, is used for storing and preserving all kinds of products. However, sometimes we may encounter the situation of slow cooling of air-cooled cold storage, i.e. the temperature inside the cold storage drops slowly. In this article, we will discuss the causes of slow cooling air-cooled cold storage, and provide some solutions.

　　1.the cause of the analysis

　　Refrigeration equipment problems: air-cooled cold storage cooling speed and refrigeration equipment refrigeration capacity is closely related. If the refrigeration capacity of the refrigeration equipment is insufficient or faulty, it will lead to slow cooling. It may be due to insufficient refrigerant, refrigeration system pressure problem or aging of refrigeration system components.

　　Cold storage adiabatic performance: poor adiabatic performance of cold storage will also affect the cooling speed. If the wall, roof or floor of the cold storage is not well insulated, it will lead to cold air leakage, thus slowing down the cooling rate.

　　Cold air circulation: air-cooled cold storage rely on cold air circulation to achieve cooling, if the cold air circulation is not good or poor fan operation, will affect the uniform distribution of cold air and rapid cooling.

　　Excessive load: If the load of goods in the cold storage is too large, the cold air can not be fully circulated, the cooling speed will be slow.

　　2.the solution

　　Inspection and maintenance of refrigeration equipment: Regularly inspect and maintain the refrigeration equipment to ensure that the refrigeration system operates normally and that the faults are repaired in time. If the refrigeration capacity is insufficient, consider increasing the number of refrigeration equipment or upgrading the equipment.

　　Enhance the adiabatic performance of the cold storage: Enhance the adiabatic performance of the cold storage, such as replacing the adiabatic material, repairing the wall leakage, etc., in order to reduce the cold air leakage and improve the cooling speed.

　　Check the cold air circulation system: Ensure that the cold air circulation system operates normally, clean the fans and air ducts to ensure that the cold air can circulate evenly and improve the cooling effect.

　　Reasonable arrangement of cargo load: Reasonable arrangement of the placement of goods to ensure that the cold air can circulate smoothly, to avoid excessive load leading to slow cooling.

　　Slow cooling of air-cooled cold storage may be caused by refrigeration equipment problems, poor insulation performance of cold storage, cold air circulation problems or too large a load. In order to solve this problem, it is necessary to maintain and overhaul the refrigeration equipment, improve the adiabatic performance of the cold storage, ensure smooth cold air circulation, and reasonably arrange the cargo load. By adopting these solutions, the cooling speed of air-cooled cold storage can be improved to ensure the quality and freshness of stored products.
