THERMOPHYSICAL PROPERTIES OF REFRIGERANTS

HIS chapter presents data for the thermodynamic and transport T

properties of refrigerants, arranged for the occasional user. The refrigerants have a thermodynamic property chart on pressure-enthalpy coordinates with an abbreviated set of tabular data for the 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 the 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 the 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 the bubble and dew-point temperatures (the “temperature glide” experi-enced with blends).Most of the 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 compar-isons. Revised formulations have been used for many of the refrig-erants; 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 diox-ide) and refrigerant blends R-404A, R-407C, R-410A, and R-507conform to ISO/DIS Draft Standard 17584, Refrigerant Properties.Reference states used for most of the refrigerants correspond to the international convention of 200 kJ/kg for enthalpy and 1kJ/(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.
