摘要
溶液换热器是高温吸收式热泵的重要部件之一。它的传热效率及其传热强化对提高系统性能,降低热泵系统的设备费和操作费是非常重要的。本文分析计算了不同传热效率对系统性能的影响,并分析了换热器传热温差与(火用)损及传热效率的关系,提出采用强化传热元件和评价热泵系统性能的关联式。
The solution heat exchanger is one of the main components of high temperature absorption heat pumps. Its heat transfer effectiveness and enhancement are very important for the improvemnt of heat pump system performance and the decrease of its equipment and operating expense. Therefore, this paper analyzes and calculates the effect of different heat transfer effectiveness on performance of heat pump system, analyzes the relationship of heat transfer temperature difference with exergetic loss and heat transfer effectiveness, and proposes the ways to employ enhanced heat transfer elements and the correlation to evaluate heat pump performance.
