Regular maintenance is the "critical safeguard" for extending the lifespan and ensuring the stable operation of cold storage units. Maintenance tasks such as cleaning condensers and evaporators, replacing lubricants, and replenishing refrigerants directly impact equipment performance and operational safety. Many cold storage facilities suffer from issues related to component aging and neglect, such as overlooking regular maintenance or failing to address potential faults in a timely manner. While this may seem to save on short-term maintenance costs, it can lead to declining equipment performance, frequent malfunctions, and, in severe cases, complete unit failure. The resulting repair costs often far exceed the initial savings.

        Delayed cleaning of heat exchange components can cause a sharp drop in efficiency. When condensers and evaporators are not cleaned over extended periods, dust accumulates on their surfaces, forming an insulating layer that significantly reduces heat exchange efficiency. This forces the refrigeration unit to operate under high loads for prolonged periods, not only drastically increasing power consumption but also accelerating the aging of core components like the compressor. Additionally, slower cooling speeds and increased temperature fluctuations inside the storage can compromise the quality of stored goods.

         Failure to replace lubricants in a timely manner and refrigerant leaks are critical risks. Unchanged lubricants degrade over time, losing their ability to effectively lubricate the compressor. This can lead to severe issues such as component wear or cylinder seizure, directly causing unit shutdown. Unaddressed refrigerant leaks result in the unit operating with insufficient refrigerant, significaantly reducing cooling capacity and exacerbating compressor wear due to inadequate lubrication, ultimately shortening the equipment's lifespan.

         Standardized maintenance requires adherence to three core principles: Regularly clean condensers and evaporators to remove dust and debris, ensuring optimal heat exchange efficiency. Replace lubricants as specified in the equipment manual to guarantee sufficient lubrication for the compressor. Periodically check refrigerant levels and pipeline sealing, promptly repairing leaks and replenishing refrigerants as needed. Additionally, maintain a maintenance log to record the timing, details, and outcomes of all maintenance activities, establishing a comprehensive maintenance cycle.

         In cold storage operation, "thirty percent is about repairs, seventy percent is about upkeep." Regular maintenance is not an additional expense but a key strategy to prevent major failures. Investing in component maintenance upfront may seem to add operational steps, but it effectively delays component aging, enhances equipment efficiency, and reduces downtime losses and repair costs. Prioritizing maintenance ensures the long-term stable operation of cold storage units, enabling them to consistently deliver their storage value.
