Abstract

The leakage of air-conditioning refrigerating system will reduce the operation efficiency and bring about serious atmosphere environment pollution. This article puts forward that the leak detection of air-conditioning refrigerating pipeline system by means of stress wave detecting, we set up the NDT system and use the LabVIEW graphical programming software which was popular currently to determine the location of leak source by using of correlation analysis. Experiments is proved that the method is practicable, and its sensing speed is quick in action and the fixed position error is smaller than 4%.
