CHAPTER 30
THERMOPHYSICAL PROPERTIES OF REFRIGERANTS
Licensed for single user. © 2009 ASHRAE, Inc.
T
HIS chapter presents data for thermodynamic and transport
properties of refrigerants, arranged for the occasional user. The
refrigerants have a thermodynamic property chart on pressureenthalpy coordinates with an abbreviated set of tabular data for saturated liquid and vapor on the facing page. In addition, tabular data
in the superheated vapor region are given for R-134a to assist students working on compression cycle examples.
For each cryogenic fluid, a second table of properties is provided for vapor at a pressure of one standard atmosphere; these data
are needed when such gases are used in heat transfer or purge gas
applications. For zeotropic blends, including R-729 (air), tables are
incremented in pressure, with properties given for liquid on the
bubble line and vapor on the dew line. This arrangement is used
because pressure is more commonly measured in the field while
servicing equipment; it also highlights the difference between bubble and dew-point temperatures (the “temperature glide” experienced with blends).
Most CFC refrigerants have been deleted. Tables for R-11, R-13,
R-113, R-114, R-141b, R-142b, R-500, R-502, R-503, and R-720
(neon) may be found in the 1997 ASHRAE Handbook—Fundamentals. R-12 has been retained to assist in making comparisons. Revised formulations have been used for many refrigerants; these
conform to international standards, where applicable. Thermodynamic properties of R-12, R-22, R-32, R-123, R-125, R-134a,
R-143a, R-152a, R-717 (ammonia), and R-744 (carbon dioxide) and
refrigerant blends R-404A, R-407C, R-410A, and R-507 conform to
ISO/DIS Draft Standard 17584, Refrigerant Properties.
Reference states used for most refrigerants correspond to the international convention of 200 kJ/kg for enthalpy and 1 kJ/(kg·K) for
entropy, both for saturated liquid at 0°C. Exceptions are water and
fluids with very low critical temperatures (e.g., ethylene, cryogens).
These data are intended to help engineers make preliminary
comparisons among unfamiliar fluids. For greater detail and a
wider range of data, see the sources in the References.
