研究目的
To analyze the economics of water production using different solid desiccant materials and composite materials through Scheffler reflector.
研究成果
Silica gel is the most economical and efficient desiccant material for water production compared to molecular sieve, activated alumina, and composite materials. The payback period for activated alumina is slightly less than that for silica gel, but silica gel offers the lowest annual cost per liter of water produced.
研究不足
The study is limited by the specific desiccant materials used and the geographical location of the experiments. The economic analysis is based on assumptions such as the useful life of the system, maintenance cost, and interest rate.
1：Experimental Design and Method Selection:
The study involved the use of a Scheffler reflector and a receiver box to produce water from atmospheric air using different desiccant materials.
2：Sample Selection and Data Sources:
Experiments were performed at National Institute of Technology, Kurukshetra, Haryana, India.
3：List of Experimental Equipment and Materials:
Scheffler reflector, receiver box, solid desiccant materials (activated alumina, molecular sieve 13X, silica gel), composite desiccant materials (LiCl/River Sand, CaCl2/River Sand, LiBr/River Sand).
4：Experimental Procedures and Operational Workflow:
The process involved adsorption/absorption at night and regeneration followed by condensation and water production during the day.
5：Data Analysis Methods:
The economic analysis included calculating the annual cost per liter of water produced using different materials.
