NEW METHOD FOR INWARD LEAKAGE DETECTION

Ales Hribernik, Gorazd Bombek

Abstract

A new non-destructive method was developed for the detection of refrigerant leakage at an evaporator’s inflow. Nitrogen and oxygen gas were blown through the evaporator in successive time intervals. A gas analyser was applied at the outflow of the evaporator and the oxygen concentration measured. It was possible to detect any leakage by investigating the oxygen concentration-time history diagram.
