日本冷冻协会于1988年5月15日颁布了学术论文赏和技术装置赏。获学术论文赏的有三篇:1.金钟秀等撰写的《冷冻机油对蒸发器性能的影响》第一报局部传热系数,第二报局部压力损失,其中论述了混有油的制冷剂的特性,预测了油对传热系数和压力损失的影响,从流动状态的观察可知,流动状态的变化比纯制冷剂快,且存在起泡沫的部位,提出了涉及平均传热系数和油浓度关系的实用相关式。油的混入影响局部压力损失的增加,提出了压力损失推算法。上述论文对实际蒸发器的
Japan Frozen Society on May 15, 1988 promulgated a dissertation award and technology installation tours. Received three academic papers: 1. Jinzhong Xiu et al., “Refrigeration oil on the performance of the evaporator,” the first part of the local heat transfer coefficient, the second part of the local pressure loss, which discusses the mixed refrigerant characteristics of oil , The influence of oil on heat transfer coefficient and pressure loss was predicted. From the observation of flow state, it can be seen that the change of flow state is faster than that of pure refrigerant, and there is a foaming site. The relationship between average heat transfer coefficient and oil concentration Practical relevance. The mixing of oil affects the increase of local pressure loss, and puts forward the pressure loss estimation method. The above papers on the actual evaporator
