请问approach temperatures翻译成什么比较好？ approach tempreture 翻译为温差。 见下面老外的评论： the temperature approach used in a shell and tube heat exchanger is simply the difference between the outlet temperature of one stream and the inlet temperature of the other stream. you can see that there are two temperature approaches. for example if you use cooling water to cool a process stream from 95 to 40°c, where the cooling water warms up from 25 to 35°c. here the greater temperature difference (hot in cold out) is 95-35=60 °c, where the least temperature difference (cold in hot out) is 40-25=15 °c. the temperature approach is significant in that the closer the approach is, the more surface you require to progress up the heating curve/down the cooling curve. it is possible to find that the overall lmtd looks reasonable, but a very close approach (or pinch) part way up the heat curves causes problems, in that a lot of surface is required to progress past it.查看更多
