【摘要】 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。更多还原

【Abstract】 After the paper "A General Computer Program of the Thermodyna- mic Properties for Fluorinated Hydrocarbons" written by this paper’s authors, the authors have solved the problem of computer program for single stage compression refrigeration cycles for twelve freons. For theoretic refrigeration cycles, the input data supplied to the computer are only condensing temperature, evaporating temperature, superheated temperature at suction state and subcooling temperature before throuttling. For practical refrigeration cycles, some additional input data are neca- ssary. Output data of this program are thermodynamic properties at the characteristic points of the theoretic refrigeration cycle and the chara- cteristic values of the cycles. Using this program the calculating speed and accuracy can be increased. Inaddition, the paper has recommend a new thermodynamic calcul- ating method for using hermetically sealed compressor in the refrigera- tion cycles.更多还原
