影响使用非共沸制冷剂混合物吸引力的一个因素是，与单一制冷剂相比，混合物的传热系数的大小。理想情况下，传热系数应保持与单一制冷剂的传热系数一样高，以便充分利用非共沸混合物的其他潜在优势。本文和其他地方报告的冷凝系数研究表明，使用混合物时，冷凝系数会降低。主要的减少发生在冷凝器的中段。在玻璃管冷凝器上拍摄的照片和观察结果表明，该区域的流动是分层的。这一发现表明，通过安装湍流促进剂或使冷凝器循环以在冷凝器的该区域获得更高的速度，可以防止系数降低。 单位:双引文:研讨会，ASHRAE交易，1985年，第91卷，pt。你好，檀香山2B

One factor affecting the attractiveness of using nonazeotropic refrigerant mixtures is the magnitude of the heat-transfer coefficient of the mixture in comparison to a single refrigerant. The heat-transfer coefficient should ideally be maintained as high as that of the single refrigernant in order to fully exploit other potential benefits of non-azeotropic mixtures.Research on condensing coefficients reported in this paper and elsewhere indicate a reduction in the coefficient when using a mixture. The principal reduction occurs in the midrange of the condenser. Photos and observations made on a glass-tube condenser indicate that the flow is stratified in this region. This finding suggests that it may be possible to prevent the reduction in the coefficient by installing turbulence promoters or circuiting the condenser to achieve higher velocities in this region of the condenser.Units: Dual
