Elements contained in hfo refrigerants
WebThe “Monitor Top” refrigerator, introduced by General Electric (9) in 1927, was considered to be the first affordable refrigerator. (10) These early units used sulfur dioxide, methyl formate, ammonia, or methyl chloride as the refrigerant—all toxic and flammable fluids. WebAfter the test, the refrigerant was collected in a gas sampling bag and used for analysis. 2.2 Analytical Method . The recovered refrigerant was analysed by gas chromatography. In addition, the water-soluble components contained in the recovered refrigerant were absorbed by water and analysed by ion chromatography. This is useful
