换热器工作状态如何,可用几项工作指标加以衡量。常用的工作指标有漏损率、换热效率和温度效率等五项,它们比较全面的说明了换热器的特点和工作状态。在生产和科学试验中了解这些指标,对于换热器的管理和改进,都是必不可少的。本文对换热器工作指标的计算,将给予新的叙述和推导。 Heat exchanger work status, available several indicators to be measured. Commonly used indicators of work have leakage rate, heat exchange efficiency and temperature efficiency of five, they give a more comprehensive description of the characteristics and working conditions of the heat exchanger. Understanding these specifications in production and scientific experiments is essential for the management and improvement of heat exchangers. This article on the calculation of heat exchanger work indicators, will give a new description and derivation.
