Abstract

In this communication, an analysis of an inverted absorber solar still, with water flowing over the condensing surface, has been presented. Analytical expressions for the hourly variation of various temperatures namely, water, condensing cover, and flowing water, the yield and the instantaneous thermal efficiency have been derived in terms of design and climatic parameters. Numerical computation has been carried out for a particular day of Delhi weather for an inverted absorber solar still with water flowing over the condensing cover. The results have been compared with those of an inverted absorber solar still without the water flow over the condensing cover. It is found that for an optimum 10cm depth of water in the basin the yield is increased by about 11 % when there is flow of water at the rate of 0.5kg/s.
提高收率的倒置吸收式太阳能蒸馏器的热分析
在本通讯中,分析了一个倒置吸收太阳能蒸馏器,与水流动在冷凝表面,已经提出。根据设计和气候参数,推导出了各种温度,即水、冷凝盖和流水、产量和瞬时热效率的小时变化的解析表达式。数值计算已经进行了一个特定的一天的德里天气的倒立吸收太阳能仍然与水流过冷凝盖。并与没有水流过冷凝盖的倒置吸收器太阳能蒸馏器的结果进行了比较。结果表明,当水流量为0.5kg/s时,池内最佳水深为10cm,产量可提高11%左右。
