Performance Improvement in Thermal Efficiency of Solar Evacuated Glass Tube Collector Using Latent Heat Storage Materials

Abstract

In the present review paper, the existing evacuated tube solar water heating systems are studied. Solar energy is available in abandonment free, environmentally clean, and therefore it is one of the most promising alternative energy sources. The effective utilization of solar energy is hindered by the intermittent in nature and its availability, limiting use of solar energy effectiveness in domestic and industrial applications especially in water heating. Now a day, plenty of solar water heater is used for domestic, commercial and industrial purposes. These review focuses of the development of research confined the techniques and technologies for the improvement in evacuated solar water heating system. In the project the main aim is to conserve the energy by using renewable energy sources like solar energy, but to overcome the major drawback of water heating system is the continuous drop of temperature, that will be consider here with the help of using PCM. The efficiency of the collector increases by 5-6 % when considering PCM with thermal energy storage tank. The proposed work that has been done mainly on the basis of energy conservation using latent heat storage Material.
