| 摘 要： | 本文利用新改进的表面张力实验系统对R600a／矿物冷冻油混合物的表面张力进行了实验研究，其中R600a的质量分数分别为O．95、0．90和0．85，温度范围为253．15-333．15K。实验结果表明，随着含油量的增加，R600a／矿物冷冻油的表面张力逐渐减小，矿物油的存在对纯质制冷剂的表面张力有比较明显的影响。

| Abstract: | The surface tension of R600a(1) +mineral refrigerant oil(2) binary mixture was measured at three nominal mass fractions of w(1)= 0.95,0.90 and 0.85 over the temperature range from 253.15 to 333.15 K by using the surface tension experimental system of new improvement.The results shows that,with the increase of oil,the surface tension of R600a+mineral refrigerant oil binary mixture has been gradually decreased,and the existence of mineral refrigerant oil greatly influences the surface tension of pure refriger... |
