National Institute for Standards and Technology and Low-Global Warming Potential Refrigerants Research Project
The U.S. Department of Energy (DOE) is currently conducting research into low global warming potential (GWP) refrigerants.
This project seeks to identify and evaluate potential low-GWP alternative refrigerants. The National Institute for Standards and Technology (NIST) will estimate their thermodynamic properties based solely on their molecular structure, allowing researchers to evaluate fluids that may have never been physically synthesized. In total, about 1,000 fluids will be considered.
In parallel, researchers will evaluate the effect of a refrigerant's fundamental thermodynamic parameters on performance in a variety of refrigeration cycles, which will define the boundaries of what is thermodynamically possible for a refrigerant and identify the optimum parameters.
Research is being undertaken between DOE and the National Institute for Standards and Technology.
The goal of this project is to identify and characterize one or more new refrigerants that would have a low-GWP along with thermophysical properties that would yield high energy efficiency in refrigeration equipment.
Benefits and Impacts
The market impact of this research should be considered in terms of viability of selecting most suitable and efficient next generation refrigerants and the avoided cost of future transitions to subsequent fluids.
