摘要
本文阐述了换热器表面热强度减小,对数平均温差减小,换热面积增大,净收益增加的关系。并得出换热器表面热强度完全可以取到5700kJ/m^2·h 以下的结论。
This article describes the relations that the logarithm everage difference in temperature decreases,heat-exchange areas and net profit incr- ease when the surface heat strength of heat-exchanger decreases,meantime, we come to the conclusion that the surface heat strength data of heat-excha- nger can be under 5700kJ/m^2·h.
