| Abstract | 本文从循环方式、喷淋方式和吸收器、蒸发器、发生器的结构形式方面对澳化铿吸收式制冷机进行了小型化研究。针对这些研究结果研制了2kW、10kW小型制冷机并进行了测试和分析。喷淋方式试验研究：对几种不同喷淋方式进行了试验性研究，并给出了各种喷淋方式的适用范围，对于单级单泵系统竖管换热结构，下开孔喷淋外绕导流线的喷淋方式效果最好。竖管换热研究：对竖管换热方式进行了实验研究，并与传统的横管排列换热方式进行了比较，证实在小流量的工况下，竖管换热方式优于横管排列。2kW制冷机试验研究：采用竖管结构研制了一台Zkw单级单泵太阳能澳化铿吸收式制冷空调系统并进行了测试，得到了运行曲线，证明了竖管结构的可行性。10kW制冷机试验研究：对吸收器、蒸发器、发生器采用盘管结构研制了一台10kW单级单泵太阳能浪化铿吸收式制冷系统并进行了测试，证明盘管结构的可行性和优越性。系统在设计环境下可得到制冷量大于10kW，并绘制了运行曲线。 |
| Other Abstract | In this paper, the circulation style, spray style, absorber, structure style of evaporator and generator of LiBr chilling system are studied for the sake of miniaturization. And we designed and studied 2kW and 10kW chillers with above productions.Spray styles study, several spray styles was studied, the suitable application conditions was laid out. For the single stage, single pump and upright heat transfer tube system, bottom holes and outer circled leading thread spray style was the best.Upright tube heat transfer study, horizontal tube and upright tube heat transfer styles were studied and compared in same outer conditions. Experimental results -confirmed that upright tube heat transfer style better than horizontal tube heat transfer style under the condition of little flux.2kW chiller study, this chiller system adopts upright tube heat transfer style, single stage, and single pump circulation style. This system was tested and analysed, we got run curves and approximate formula.10kW chiller study, in this chiller, absorber, evaporator and generator adopt twist tube structure style, and the system was single stage, and single pump circulation style. This system was test and analysed, experiment results testified that the twist tube structure was doable. Under the design conditions, the chiller could get chilling capacity over lOkW, and run curves were drawn |
