Experimental Investigation of an Inclined Combined Solar Hot Water and Desalination System

The main aim of this research is to design a new solar collector for heating the water and use it in water desalination. This study gives information about the inclined solar water desalination and heating system design, construction and the results of the system. The performance of the inclined solar water desalination and heating system was studied with different mass flow rates and systems. Different systems and mass flow rates were compared. In this study 6 different mass flow rates and 2 different systems were tested. In the first system, two different storage tanks were used. In the first system one storage tank sends the water to the solar collector and then hot water goes to second storage tank. There is no circulation in this system. This system was tested with 3 different mass flow rates and the average efficiency of the system is 65% and average daily water production is 2134,1 ⁄. In the second system one storage tank was used. The second system has circulation and because of this the inlet temperature of the water increases. The same water circulates in this system and this reduces the water quality. This system was tested with 3 different mass flow rates. The average efficiency of the system is 72% and daily average water production is 2833.17 ⁄. The cost of the collection and payback analysis of the system are shown in the economic analysis section.
