Air tightness is the key to ensuring the stable operation of cold storage units, as it directly relates to the tightness of the refrigeration system and the normal operation of refrigerant. Poor unit air tightness, caused by insufficient factory leak detection, is a major hidden danger that easily leads to system failures.

         Poor air tightness of the unit will lead to refrigerant leakage, which not only reduces the refrigeration efficiency and increases energy consumption but also causes unstable cooling temperature, failing to meet the storage needs of cold storage and shortening the service life of components.

         Insufficient factory leak detection is the main cause of poor air tightness. Negligent leak detection procedures or unqualified detection standards will fail to identify potential leakage points, allowing unqualified units to leave the factory and lay hidden dangers for subsequent operation.

         The hidden danger of poor air tightness is not easy to be found in the early stage, but it will cause serious losses in long-term operation, including increased maintenance costs, abnormal shutdowns and reduced storage quality.

         Strict factory leak detection is the fundamental guarantee for good air tightness of cold storage units. Standardizing the leak detection process and improving detection standards can effectively avoid poor air tightness and ensure the stable and efficient operation of the unit.

         Paying attention to unit air tightness and strengthening factory leak detection can eliminate potential leakage hazards, reduce operational costs, and lay a solid foundation for the long-term stable operation of cold storage.
