ASHRAE is conducting a research gathering process on information about a new refrigerant with zero-ozone depletion potential and low global warming potential. R-245fa is suitable for low-pressure water chillers typically used in large building air conditioning. Equipment also is being developed using R-245fa in other heat transfer and working fluid applications. Among them is 1256-TRP, Thermophysical Properties of R-245fa. The principal investigator is Alexandre Grebenkov, Ph.D., Institute of Power Engineering Problems, Sosny, Minsk, Republic of Belarus. The project is expected to take 10 months to complete at a cost of $55,500. It is sponsored by ASHRAE Technical Committee 3.1, Refrigerants and Secondary Coolants.
