作者在“氟利昂热力性质通用计算程序”的基础上,进一步解决了适用于12种氟利昂的单级压缩式制冷循环的热力计算程序问题。对于理论循环、输入计算机的数据仅为冷凝温度、蒸发温度、吸汽过热度及节流阀前过冷度。对于实际循环,尚需输入少量必需的数据。计算机输出为理论制冷循环各关节点的热力性质,以及循环的各种特性数据。运用计算机不仅大大提高了计算速度,而且能获得精确的数值解答。本文还介绍了采用全封闭压缩机制冷循环热力计算的新途径。
The author further solves the problem of thermodynamic calculation procedure of single-stage compression refrigeration cycle applicable to 12 Freon based on “Freon thermodynamic general calculation program”. For the theoretical cycle, the data entered into the computer is only the condensing temperature, evaporating temperature, suction superheat and throttle precooling. For the actual loop, a small amount of required data needs to be entered. The computer output is the thermodynamic properties of the various points of the theoretical refrigeration cycle, as well as various characteristics of the cycle data. Using a computer not only greatly increases the speed of calculation, but also get accurate numerical solution. This article also introduces a new approach to the thermodynamic calculation of a refrigeration cycle using totally enclosed compressors.
