Abstract:

本文在收集了制冷剂R11、R12、R13、R22、R23、R32、R13B1、R113、R114、R123、R124、R125、R134a、R141b、R142b、R143a、R152a、R227ea、R236ea、R236fa、R245ca、R245fa、R1234yf、R1234ze及其二元和三元混合物黏度数据的基础上,结合自由体积理论和混合法则建立了一种可以计算制冷剂及其混合物黏度的推算模型。对于纯质制冷剂的黏度,模型预测值与实验值之间的相对偏差绝对平均值小于1.5%,最大相对偏差绝对值小于3.1%。对于制冷剂二元和三元混合物的黏度,模型预测值与实验值之间的相对偏差绝对平均值小于3.6%,最大相对偏差绝对值小\linebreak于7.5%。
