Study on Regulating Technique of Material Flow for 2-person and 30-day Integrated CELSS

摘要

A man-plant compositive test was achieved using the CELSS Integration Experiment Platform in which 4 kinds of plant were grown(Lactuca sativa L var. Dasusheng,Lactuca sativa L var. Youmaicai, Gynura bicolor and Cichorium endivia L) to exchange material with 2 persons for 30 days in order to research the dynamic changing laws and balanced regulating of air and water between man and plant in an enclosed system. The material closure degree of air,water and food reached 100%,90% and 13.9% respectively with the whole system closure degree up to 80.0% .Meanwhile, it was proved that 13.5m2 of plants could satisfy the demand of one person for 02 in the system, the energy efficiency ratio of which reached 59.56 g/ (kWm2day) . The regulating technology for material flow dynamic balance was initially mastered between men and plants through the test.The interaction was recognized among the persons, plants and the surrounding environment in the enclosed system,which is of great significance to the advancement of long-term manned environment control and life support technology in the future.
