Study on Self-circulation Thermal Management and Power Generation System Applied in Lunar Base
According to the demand of the lunar base for thermal management,a new type of self-circulation thermal management and power generation system is designed according to the character-istics of the lunar surface thermal environment.The system combines the Organic Rankine Cycle(ORC)and the Ejector Refrigeration Cycle(ERC).The equipment heat and solar or nuclear waste heat is taken as the heat source,while the external cold background is taken as the cold source.Part of the system working medium absorbs the heat source and realize ORC electric power genera-tion,while the other part of the system working medium absorbs heat from astronauts through the e-vaporator in the daily working environment,thus provide cooling for spacesuits and scientific resear-ches.The system can operate independently to achieve power generation and cooling without any needs of external power.According to the analysis,on the basis of meeting the needs of heat collec-tion,transmission and distribution of the lunar base,the maximum waste heat cooling rate can reach over 40%,and the total waste heat utilization efficiency can reach over 50%.
