Leak detection and operation records before the delivery of cold storage are key links to avoid later failures and ensure the long-term operation of equipment. Delivering without leak detection and operation records is a serious process omission, which will leave many potential safety and failure hazards.

         Failure to perform leak detection cannot timely find the hidden danger of refrigerant leakage in pipelines and interfaces. After delivery, it is easy to have insufficient refrigeration capacity, soaring energy consumption, and even cause corrosion of equipment components and system paralysis, greatly increasing operation and maintenance costs. Delivering without operation records will lead to the lack of data support for later operation and maintenance, making it impossible to accurately troubleshoot faults, calibrate operation parameters, and trace the initial operation state of the equipment.

         Such hidden dangers originate from the irregular delivery process. It is necessary to strictly complete system leak detection before delivery to confirm no leakage hazards, and record key information such as equipment operation parameters and commissioning results in detail, so as to ensure the compliance of the delivery process, lay a foundation for the later operation and maintenance and fault troubleshooting of the cold storage, and ensure the stable operation of the equipment.
