摘要

基于月球特有的极端环境设计了一种面向月球基地的冷电联供系统

同时筛选出合适的混合工质进一步对系统进行了改良。为冷电联供系统筛选了3种合适的混合有机工质

并针对应用混合工质的系统和应用纯工质的系统进行对比

分析了混合工质系统的优点

最后针对基于混合工质的冷电联供系统的特性参数进行计算分析。结果表明:混合工质系统的最大净输出功率比纯工质系统高出12%~21%

最大效率比纯工质系统高约3%;经计算分析后得出4种典型工况下冷电联供系统均满足月球基地对散热、制冷和节能的需求

月夜期间最大发电量为1 128.29 W

最大制冷量为13.32 kW;月昼期间最大发电量为1 471.66 W

最大制冷量为13.36 kW。

Abstract

Based on the unique extreme environment of the moon

a combined cooling and power (CCP) system for lunar base was designed and subsequently improved by selecting appropriate mixed working fluids. Three suitable mixed organic working fluids were screened for the CCP system

and a comparative analysis was conducted between the systems utilizing mixed and pure working fluids to highlight the advantages of the mixed-fluid system. Finally

the characteristic parameters of the CCP system based on mixed working fluids were calculated and analyzed. The results show that the maximum net output power of the mixed-fluid system is 12%-21% higher than that of the pure-fluid system

and the maximum exergy efficiency is about 3% higher. Furthermore

the analysis demonstrates that the CCP system satisfies the lunar base's requirements for heat dissipation

cooling and energy saving under four typical operating conditions. During the lunar night

the maximum power generation is 1 128.29 W

and the maximum cooling capacity is 13.32 kW. While during the lunar day

the maximum power generation is 1 471.66 W

and the maximum cooling capacity is 13.36 kW.
