| Abstract: | 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. |
