| Popis: | Solar absorption air-conditioning system is a hot spot for solar energy application. The key to high system performance lies in the improvement of energy utilization efficiency. On this purpose, the solar steam regeneration method has been proposed: adopting material with special structure, it locates solar energy in the event of evaporation and minimizes heat loss. However, this method has only been applied on evaporation of pure water, no researches have yet been made on absorbent solutions. To reveal the actual performance of this method for absorption system, both theoretical and experimental work have been done in this paper. Models have been developed and some important parameters have been investigated. Preliminary test of the regeneration process has been carried out. Through analysis, the paper exposes the influences of the solution concentration and absorbent variety. With the solar steam method, the efficiency has been increased by 2 or 3 times, approached 40% in experiments. Beyond higher performance, this new method also has advantages on cost and stability, making it a competitive choice for future application. |
