Abstract

The functioning of a habitable lunar base requires not only electricity but also heat energy that can be produced from electricity exclusively according to the existing projects. The use of clean solar heat energy faces a number of difficulties in the practical implementation of solar power plants due to the need for its accumulation and storage during lunar night that lasts 14.75 Earth days. The article considers the scheme of a habitable lunar base solar hot water system which is operable during the lunar day and night and includes flat-plate solar collector with hydrogen heat transfer agent and seasonal heat accumulator in the lunar soil filled with crushed regolith to maintain hot water temperature during lunar night. There are presented the results of the estimation of the solar system design parameters and performance analysis based on the developed mathematical model and computer simulations of dynamic modes of operation of the solar system, located on the equator and the middle latitudes of the Moon.
