本文把可用能分析的方法引入到蓄热式热交换器热工特性的研究中 ,提出的可用能效率综合了传热和流动两方面的因素。研究表明可用能效率比温度效率和热效率能更真实反映蓄热式热交换器的热工行为 ,并可用于指导蓄热式热交换器的优化设计。
In this paper, the method of available energy analysis is introduced into the research of thermal characteristics of regenerative heat exchanger. The available energy efficiency proposed combines the factors of heat transfer and flow. The research shows that the available energy efficiency can reflect the thermal behavior of the regenerative heat exchanger more faithfully than the temperature efficiency and thermal efficiency and can be used to guide the optimization design of the regenerative heat exchanger.
