Experimental Study of the Performance of Solar Evaporative Watercooler with Clay Tank.

The main goal of this research is to use integrated solar photovoltaic systems to cool drinking water evaporative cooling. For this purpose, a traditional system including a clay tank for cooling drinking water, which is equipped with a solar photovoltaic auxiliary system, was investigated experimentally. This device made by the author, which includes an old terracotta tank with holding equipment and a photovoltaic panel, along with six cooling fans was tested. The tests include investigating the effect of environmental factors and solar energy on the performance of this cooling water system. The testing process consists of the investigation of the traditional mode and the evaluation of the amount of cooled water and its comparison with the method of using the photovoltaic system and auxiliary fans. The research results showed that this type of water cooler has a maximum efficiency of about 16% in a normal state, and with the use of photovoltaic fans, the efficiency increases by about 9.5%. Also, in traditional mode, the device has the ability to cool water up to 15 °C lower than the ambient temperature, and if the photovoltaic system is used, this amount of cooling will be more than 21 °C that indicates suitable cooling for drinking water in summer and compared to some previous studies.
