Evaluation of HCFC Alternative Refrigerants
It is well-known that HCFC refrigerants widely used in today’s air conditioning and refrigeration (AC&R) industry will soon be phased out, mainly due to their ozone depletion potentials (ODPs) and global warming potentials (GWPs). The timetable established through international agreement and national legislation calls for a 65% reduction of HCFC consumption based on 1989 level by January 1, 201...
متن کاملGlobal emissions of refrigerants HCFC-22 and HFC-134a: unforeseen seasonal contributions.
HCFC-22 (CHClF2) and HFC-134a (CH2FCF3) are two major gases currently used worldwide in domestic and commercial refrigeration and air conditioning. HCFC-22 contributes to stratospheric ozone depletion, and both species are potent greenhouse gases. In this work, we study in situ observations of HCFC-22 and HFC-134a taken from research aircraft over the Pacific Ocean in a 3-y span [HIaper-Pole-to...
متن کاملGrowth rates of stratospheric HCFC-22
The Michelson Interferometer for Passive Atmospheric Sounding onboard ENVISAT (MIPAS-E) offers the opportunity to detect and spectrally resolve many atmospheric minor constituents affecting atmospheric chemistry. In this paper, we describe an algorithm produced to retrieve HCFC–22 profiles from MIPAS-E measurements made in 2003 and present results from this scheme between 300 and 50 mb. By comp...
متن کاملHfc - 23 Emissions from Hcfc - 22 Production
The compound HFC-23 (Trifluoromethane or CHF3), a potent greenhouse gas with a 100-year global warming potential of 11,700, is generated as a by-product during the manufacture of HCFC-22 (chlorodifluoromethane or CHClF2). This paper outlines options and issues for good practice guidance in the national inventory management of HFC-23 emissions from HCFC-22 production. The issues presented are or...
