AI Technical Summary
Existing refrigerant leak detection methods suffer from high detection costs, complex operation, long processing times, and high safety risks, especially in large-scale equipment or batch testing scenarios.
An automatic mixing, charging, and pressure-holding detection device was designed, including a first charging main pipe, a second charging main pipe, a manifold, and multiple charging branch pipes. The device achieves independent charging and automatic mixing of refrigerant and nitrogen through solenoid valves and pressure transmitters, and uses a PID algorithm for progressive charging and pressure control.
It enables low-cost and efficient refrigerant leak detection, simplifies the operation process, reduces safety risks, and improves detection efficiency and safety.
