“…Kashiwa introduced a theoretical basis for the feasibility of the Solar Cyclone, suggesting that an experimental study of the separation device would be worthwhile. Akbarzadeh et al [21] suggested the utilization of a solar pond instead of collector in the solar chimney and built a small model of that. The thermal energy that stored at the bottom of the solar pond is used in a heat exchanger to heat up the air.…”

A B S T R A C TIn this article, a new combination of solar chimney and Humidification-Dehumidification desalination process is introduced. In this system, the air is humidified by injection of water drops into the air flow. Then, the partial of vapors contained in the air is condensed on the outer surface of the cold water tubes. Two mathematical models have been developed for a one-dimensional flow in the solo solar chimney and the integrated system. The performance of the integrated system including power and potable water production is estimated and the results are discussed. Furthermore, it has been demonstrated that increasing in the temperature and mass flow rate of humidifier inlet water would improve the performance of the integrated system. It is found that the increase in water production would cause the decrease in power output. Also, to produce more fresh water, the number of dehumidifier tubes should be increased.

The main objective of the work was to use solar energy for desalination of water. A solar chimney desalination system, which includes the solar chimney, solar collector, evaporation system, and passive condenser, was designed and built. The air enters into collector and gets heated and released at the bottom of chimney. Due to draught effect dry air goes upward. The air is humidified by spraying salt water into the hot air stream using a mistifier at the middle of chimney. Then, the partial vapours contained in the air are condensed to give desalinated water. The performance of the integrated system including power and potable water production was estimated and the results were discussed. With a 3.4 m height setup, experimental test rig was capable of evaporating 3.77 L water daily condensing 2.3 L water. It is compact in nature as it is easy to assemble and dissemble. It can be used for purifying rain water in summer under rain water harvesting. Because of using country wood, recycled Al cans, and GI sheet in fabrication, it is lower in cost.

Renewable energy resources are the pillars for energy sustainability. Topping those resources is solar energy. The problem with solar is the interruption during the night and the cloudy and rainy times. Many techniques have been proposed to enhance solar utilization and minimize the effect of solar interruption. This paper summarizes the author's experience on enhancing the solar thermal systems by means of integration with either other energy resources or integration with thermal energy storages. On solar drying applications, a solar dryer was integrated with a thermal backup unit. The experimental results on hybrid drying showed an enhancement of 64.1% for EFB, and 61.1% for chilli, compared with open solar mode drying. Solar water heating was found to be sufficient to supply hot water during the day and night time by integration with thermal energy storage. The system was able to discharge thermal energy and maintain the heating of water to the next morning. On large scale and industrial application, a modified inclined solar chimney was enhanced via integration with wasted flue gas. By this technique, the system was brought to operate 24 hours a day. At 800 W/m 2 solar intensity, the efficiency was enhanced to over 0.6% in the case of hybrid operation compared to less than 0.3% for solar mode only. Research results demonstrate that integrated solar thermal systems can contribute effectively in sustainability of clean energy resources. The results obtained, so far, from this research program are encouraging; and it is highly recommended to further investigate the solar hybrid and solar integration for energy sustainability from the sun.
