Abstract

[0002] Currently, in modern refrigeration systems, the storage and transportation of refrigerants are crucial links. Refrigerants are usually stored in high-pressure cylinders. These cylinders must meet extremely high safety standards to ensure that the refrigerant does not leak into the environment. Due to various reasons, including fatigue, corrosion, physical damage or improper operation of the cylinder material, refrigerant cylinders may leak. Once a leak occurs, it will not only cause economic losses, but more importantly, it may cause serious damage to the environment.

This detection method is simple and efficient, but it still has shortcomings in actual use. The entire charging pipeline is long. If only the position of the charging joint is monitored, other positions of the charging pipeline will be missed, resulting in missed detection. Refrigerant leaks cannot be discovered in time, posing a major safety hazard to the refrigerant cylinder inflation. Utility Model Content

[0028] Specifically, during the inflation process, the handle on the front surface of the front panel 7 is manually pulled, and the front panel 7 is pulled to the right, so that the front panel 7 moves horizontally between the first slide rail 15 and the second slide rail 17.
