Résumé

Hydrofluoroolefins (HFOs) play an important role in industry, it is recognized that (HFOs) containing unsaturated bonds in their molecular structure have a shorter atmospheric lifetime than hydrofluorocarbons (HFCs) and thus have a lower global warming potential (GWP) and due to increasing concerns about global warming and ozone depletion, the development of Refrigerants is becoming increasingly important and highly attraction for air-conditioning applications in the international community. which offers high energy efficiency and low global warming potential (GWP), resulting in low overall environmental impact and improved energy efficiency. In this paper, the authors will summarize thermal stability test results, ASHRAE Standard 97 and ASHRAE Guideline 38 accelerated compatibility testing methodologies, for R1132a and materials compatibility of select Metals. We conducted an experimental study on the design parameters that are important for life temperature, contamination (moisture, and Air) with various polyolester (POE) and polyether (PAG) lubricants.
