运用计算机处理制冷工质热力性质数据是制冷技术中应用计算机的一项基础性工作。为此,许多学者做了大量的工作。本文参照J.T.Mcmullan,D.W.Hughes和R.Morgan的文章“Asuit of computer programs for calculation refrigerant properties”进行了改进和完善,给出了适用于13种常用制冷工质(R-11,12,13,13B1,14,21,22, 23,113,114,500,502, C318)的通用计算程序。该程序能够计算、为主程序方便地调用并打印出任一工质、任选相区、任选单位制、任选焓熵参考态、任意数据间隙的热力性质数据。稍作改动,可绘制出13种工质的压焓图。
The use of computers to deal with the thermodynamic properties of refrigerant is a basic work of computer application in refrigeration technology. To this end, many scholars have done a great deal of work. This paper improves and perfects the article “Asuit of computer programs for calculating refrigerant properties” by JTMcmullan, DW Hughes, and R. Morgan, and gives a description of a refrigerant suitable for use in 13 commonly used refrigerant refrigerants (R-11,12,13,13B1 , 14, 21, 22, 23, 113, 114, 500, 502, C318). The program can calculate and print the thermodynamic properties of any working medium, optional phase area, optional unit system, optional enthalpy entropy reference state and any data gap for the main program. A slight change, you can draw the 13 enthalpy chart of the working fluid.
