Design of an all-weather water extraction system based on solar energy and diurnal temperature difference

Abstract

According to the survey, the water content in the air is as high as 14,000 km3. To make full use of the moisture retained in the air, we designed this all-weather water extraction system based on solar energy and the temperature difference between day and night. The system uses solar power panels to supply power to the micro-suction fan during the daytime, builds a condensation structure of “air-ground”, and uses the natural temperature difference between day and night to condense water at night and store it in the buried water reservoir. Semi-arid areas have water demand and have the advantages of all-weather use, fast water extraction, low cost, and ease of promotion.
