Refrigeration System Leak Testing to Reduce Freon Loss
Refrigeration System Leak Testing to Reduce Freon Loss The leak testing of pipe joints, fittings and tubes in refrigeration and heating components, such as compressors and coils, is vital throughout assembly manufacturing. Conventional sniffer testing is not a reliable technique to detect small leaks, with the permissible leak rate as small as 0.5 grams of refrigerant loss per year. In order to detect helium escaping from a leak, sniffer tests sample leaks compared to background. Yet, background helium concentration fluctuations can make it challenging to distinguish good from...
