Logarithmic mean temperature difference 對(duì)數(shù)平均溫差
In the deducing process , no specific flow mode is presupposed , and the conclusion of temperature subtracting by the same side for logarithmic mean temperature difference can be easily drawn 推導(dǎo)過程無需假定冷熱流體的特定流向,并利于得到對(duì)數(shù)平均溫差“同側(cè)相減”的規(guī)律。
