To conduct a systematic study of Natural Fluids as working fluids for heat pumping applications, it was necessary for NIST to simultaneously expand its analytical tools and evaluate what design changes American industry would most readily accept. The problem was approached by categorizing all potential working fluids into one of three vapor pressure groups - high, intermediate, and low - and evaluating disadvantages presented by each category. The intermediate group spans the range covered by the CFCs that have been traditionally used (i.e., R-502 to R-11). An example of the high and low-pressure refrigerants are CO2 and H2O, respectively.
