Description
This chapter presents data for thermodynamic and transport 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 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. 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. Hydrogen and parahydrogen (R-702 and R-702p) may be found in the 2009 ASHRAE Handbook–Fundamentals. A new table and diagram for R-1233zd(E) have been added, and the data for R-245fa and R-1234ze(E) have been revised. Viscosity data for R-1234yf have been revised. The formulations 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 Standard 17584, Refrigerant Properties.
