The log mean temperature difference (LMTD) isused to determine the temperature driving force for heat transfer in flow systems, most notably in heat exchangers. The LMTD is a logarithmic average of the temperature difference between the hot and cold streams at each end of the exchanger. What is...
Sometimes direct knowledge of the LMTD is not available and the NTU method is used. 在多数简单系统这是“日志平均温差” (LMTD)。 有时LMTD的直接知识不是可利用的,并且使用NTU方法。 [translate] a设计了该发变组主断路器控制回路 Designed this round to change the group main circuit breaker control ...
