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
