Development of Refrigeration Oil for Use With R32
, 2012 R410A, which has a high GWP (global warming potential) of roughly 2000, is widely used in refrigeration systems today. Various low GWP alternative refrigerants have been investigated as part of the effort to stop global warming. One such refrigerant, R32, offers an alternative that improves system performance without the need for significant changes to
