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 کاملNew Chemical Alternative Refrigerants
Due to the increased public concern over the role that chlorofluorocarbons CCFCs) play in depleting stratospheric ozone, a landmark international agreement , the Montreal Protocol, was signed in 1987 which regulated the production and consum ption of CFCs. More recently, several nations, most notably Canada, the Federal Rep ublic of Germany, Norway, Sweden, and the United States, have planned o...
متن کاملNew, Natural and Alternative Refrigerants
It is good to be able to pass on the best wishes of the International Institute of Refrigeration (IIR) and to remind you that the IIR will be holding its Gustav Lorentzen Memorial Conference in Glasgow next year. I hope that the IIR conference will be as well supported and as valuable as this CIBSE/ASHRAE conference. You are warmly invited to attend the Gustav Lorentzen conference in Glasgow, w...
متن کاملThermophysical Properties of Some Selected Alternative Refrigerants
A summary of a thermophysical properties program for six candidate alternative. refrigerants is given. This work has been performed recently at the National Institute of Standards and Technology (U.S.A.), Thermophysics Division, in Gaithersburg, Maryland. Properties measured include gas and liquid·phase PVT, vapo~ pressures, surface tension, index of ~efraction, dielect~ie eons~ant, gas phase s...
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...
