本文介绍了作者近些年来在用计算机进行制冷工程热力计算方面所做的一些工作。作者以马丁-候公式作为气体状态方程,编制了造用于R11、R12、R13、R14、R21、R22、R23、R113、R114、R500、R502、RC318等12种氟利昂的热力性质通用计算程序,氟利昂制冷循环热力计算程序,两级压缩制冷循环及最佳中间温度计算程序,以及用微型计算机进行上述12种氟利昂的热力性质计算程序。文中介绍了程序编制过程中遇到的一些主要问题。程序执行结果表明,氟利昂热力性质数据与IIR及ASHRAE近期发表的数据非常吻合。
This article describes some of the author’s work in recent years in computer thermal engineering calculation of refrigeration engineering. Based on the Martin-Hou formula as the gas equation of state, a generalized calculation program for the thermodynamic properties of 12 freons, including R11, R12, R13, R14, R21, R22, R23, R113, R114, R500, R502 and RC318, Freon refrigeration cycle thermodynamic calculation program, two-stage compression refrigeration cycle and the best intermediate temperature calculation program, and the use of microcomputers for the above-mentioned 12 kinds of Freon thermal properties calculation program. This article describes some of the major problems encountered in programming. The program execution results show that the thermodynamic properties of Freon are in good agreement with the data recently published by IIR and ASHRAE.
