1、30.1CHAPTER 30THERMOPHYSICAL PROPERTIES OF REFRIGERANTSHIS chapter presents data for thermodynamic and transportTproperties 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

2、for sat-urated liquid and vapor on the facing page. In addition, tabular datain the superheated vapor region are given for R-134a to assist stu-dents working on compression cycle examples.For each cryogenic fluid, a second table of properties is pro-vided for vapor at a pressure of one standard atmo

3、sphere; these dataare needed when such gases are used in heat transfer or purge gasapplications. For zeotropic blends, including R-729 (air), tables areincremented in pressure, with properties given for liquid on thebubble line and vapor on the dew line. This arrangement is usedbecause pressure is m

4、ore commonly measured in the field whileservicing equipment; it also highlights the difference between bub-ble and dew-point temperatures (the “temperature glide” experi-enced 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-50

5、3, and R-720(neon) may be found in the 1997 ASHRAE HandbookFundamen-tals. R-12 has been retained to assist in making comparisons. Hy-drogen and parahydrogen (R0702 and R-702p) have been deletedfrom this edition; these may be found in the 2009 ASHRAE Hand-bookFundamentals. New tables and diagrams for

6、 R-1234yf andR-1234ze(E) have been added. The formulations conform to inter-national standards, where applicable: thermodynamic properties ofR-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 blendsR-404A, R-407C, R-410A, and R-507 conf

Exceptions are waterand fluids with very low critical temperatures (e.g., ethyl
