Experimental Analysis Of A Solar Still With And Without Phase Change Material Under Climatic Conditions Of Vijayawada, India

Water is the main need for any kind of living things. The main source of the water on earth is Sea water. We have fresh water lakes and rivers around the world for drinking purpose, but the scarcity of water came in to existence in 20th century. Therefore, we need to use sea water, which is very plenty around the world, but presently the sea water is not used for drinking purpose. So, we need to convert the salt water in to fresh water for drinking purpose. There are many ways to convert salt water in to fresh water. The converting of salt water in to fresh water, we need more amounts of any type of sources like fuels, solar etc. This paper represents a water purification technique using solar energy named as solar desalination. Even though a lot of work has been done in previous research by using solar desalination technique, the use of Phase Change Material (PCM) to increase the efficiency of the solar still and compare the performance of the solar still with PCM and without PCM. A simple single basin stage still with an inclined transparent surface for the collection of condensed vapors as they fall down. The main purpose to use PCM is to increase the productivity during evenings (when sun is absent).
