Hidden refrigerant leakage gradually reduces cooling performance of piston refrigeration compressor. Mastering reliable leak detection methods helps engineers find tiny leaks before system capacity drops significantly. Soap bubble test is widely used for on-site inspection. Apply soap liquid on welding seams, flange joints and valve stems. Continuous bubble generation indicates refrigerant escaping from the point. It is simple and low cost for routine check. Electronic refrigerant leak detector is more sensitive for small leakage. The portable instrument can trace trace refrigerant vapor and locate micro leaks, suitable for inspection after long time running. Ultrasonic leak detector picks up high-frequency sound from leaking high-pressure gas. It works well in noisy compressor room where electronic detector is disturbed by background gas. Leak points commonly appear at pipeline welding positions, compressor shaft seal, gasket flanges and service valve packing. These areas bear vibration and temperature cycle stress. After leak repair, perform nitrogen pressure holding test again. Do not refill refrigerant until leakage is fully eliminated. Adding refrigerant repeatedly without fixing leak will cause repeated failure. xtldcool provides leak detection training guidance for customers’ refrigeration technicians. We also supply pressure test procedure for post-repair verification. Refrigerant leak is not only capacity loss issue, many refrigerants also carry environmental restriction, uncontrolled release violates local environmental rules. FAQ Q: What is the simplest on-site refrigerant leak detection method? A: Soap bubble test applied on joints and welds. Q: What tool detects tiny trace refrigerant vapor leakage? A: Portable electronic refrigerant leak detector. Q: Where are the most frequent refrigerant leak positions? A: Weld seams, flanges, shaft seal and service valve packing. Q: What test must be done after leak point repair? A: Nitrogen pressure holding test to confirm no leakage. Q: Is it acceptable to add refrigerant without repairing leak? A: No, leakage point must be fixed first before recharging refrigerant. Q: What is the advantage of ultrasonic leak detector? A: Can work normally in gas-contaminated noisy compressor room. Q: What other problem besides cooling loss comes with refrigerant leakage? A: Uncontrolled refrigerant emission violates environmental regulations.
