摘要
根据国外最新实验资料，经过理论分析和计算机绘图，给出了R134a的制冷及热泵理想朗肯循环性能计算的公式及结果，以及压力比、单位制冷量及热力性能系数对蒸发温度和冷凝温度的关系曲线图，并对其进行了分析。可供设计和研究采用这种工质的制冷设备和热泵时参考。
By means of theoretical analysis and computer plotting,after the latest testing results from abroad,the paper offers formulas and the results of property calculations from the R134a refrigeration and the heat pump ideal Rankine cycle. Further it enumerates the relative diagram of curves between the pressure ratio,the refrigeration capacity and thermodynamic properties coefficient to evaporation temperature and condensation temperature, at the same time, these curves would be useful and helpful for designing and researching these refrigeration equipments and heat pumps adopting the working fluid.
