A project has been carried out on the containment, and more specifically the leak tightness, of installations using CO2. The objectives are to define a test procedure for the qualification, regarding containment, of components used on installations working with CO2. The three stages of the project are : a) to define a test procedure in collaboration with a group of refrigeration companies, b) to test the sealing ability of components following the newly built procedure, and c) to detect and measure leaks on installations in service in order to observe the feasibility of the detection method and to measure the real leaks. This article describes the test procedure for CO2 components, the results of the lab tests and the results and observations of the on-site detections.
