Ambient concentrations of eight predominantly anthropogenic halocarbons were measured via in situ gas chromatography in California's South Coast air basin for both summer and fall during the 2005 Study of Organic Aerosols at Riverside (SOAR). Ongoing emissions of the banned halocarbons methylchloroform and CFC-11 were observed in the South Coast air basin, whereas CFC-113 emissions have effecti...

A ternary blend of refrigerants composed of HCFC-22, HCFC-142b (chlorodifluoroethane), and a small amount of isobutane, has been used as a drop in substitute for CFC-12 and R-500 refrigerants. It's use as a refrigerant was presented at the Purdue 1992 International Refrigeration Conference--Energy Efficiency and New Refrigerants[ I] . This paper will cover safety related issues and testing perf...

This paper presents the experimental performance analysis of a window air conditioner using two refrigerants R22 and R410A.The effect of the different parameters of performance analysis (refrigeration capacity, COP, compressor power ,pressure ratio ) were investigated for various evaporating temperature and ambient temperature. .The result shows that refrigerant R22 is better than R410A in case...

We report a cluster of acute hepatitis in five air-conditioning maintenance workers following accidental exposure to 2,2-dichloro-1,1,1-trifluoroethane (HCFC-123). They presented to us with complaints of feverishness, generalised malaise, and epigastric discomfort. Their blood biochemistry tests were compatible with acute hepatitis. Viral hepatitis serology, tests for autoimmune hepatitis, and ...
