THERMOPHYSICAL PROPERTIES OF REFRIGERANTS

T

HIS chapter presents data for thermodynamic and transport  properties of refrigerants, arranged for the occasional user. 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, includin g R-729 (air), tables are incremented in pressure, with properties given for liquid on the  bubble line and vapor on the dew lin e. T his arrangement is used   because pressure is more commonly measured in the field while servicing equipment; it also highlights the difference between bub ble and dew-point temperatures (the “temperature glide” experienced with blends).

Most CFC refrigerants have been d eleted. Tables 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 1997 ASHRAE Handbook—Fundamentals. tals. 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 ISO/DIS Draft Standard  17584,  17584, Refrigerant Properties. Reference states used for most refrigerants corre spond 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.

CHAPTER 30

THERMOPHYSICAL PROPERTIES OF REFRIGERANTS

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 atmosph ere; 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 d ew line. This arr angement is used  because pressur e is more commonly measured in the field while servicing equipment; it also highlights the d ifference between bub ble 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 American convention of 0 Btu/lb for enthalpy and 0 Btu/lb·°F for  entropy for saturated liquid at –40°F. 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.
