Description

The objective of this project is to experimentally investigate the robustness and leak-tightness of various field-made mechanical joints used to connect refrigerant piping and system components for any kind ofHVAC&R application employing flammable refrigerants (ASHRAE Standard 34,classes A2L, A2, or A3). The focus of the study is on flame-free joining methods, such as flare, compression, or crimp/press type fittings used in field installation or field service. The motivation of the work is seen in the desired use of various low-GWP refrigerant candidates that are flammable. While any refrigerant joint should be leak-free, the added safety concerns due topotential flammability issues increase the need to identify and characterize suitable joining techniques for refrigerant piping and components. ASHRAE Standard 147 provides further information on current industry component and product design requirements to limit refrigerant leakage as well as acceptable leaks in stationary equipment. The outcome of this research is seen as important input to various ASHRAE standards and other relevant codes related to refrigerant safety as well as for the industry in general.
