- Abstract
- The need for, and uses of thermodynamic and transport properties in the selection of working fluids for the vapor compression cycle and in equipment design are reviewed. Lists of hydrogen-containing halocarbons, as well as their mixtures, are presented as alternatives to the environmentally-harmful, fully-halogenated chlorofluorocarbons. These fluids range from well-characterized, widely-available refrigerants to materials available only by custom synthesis about which very little is known. Data priorities for these fluids are presented; most essential are critical point, vapor pressure, liquid density, ideal gas heat capacity, and vapor p-V-T data. A critical need exists for these data on a number of candidate working fluids in order not to lose the opportunity to select the best set of future refrigerants.
