Abstract

Abstract: The depletion of natural energy resources are the major concern in the world therefore the researcher's focus is to utilize the renewable energy resources such as solar, wind, tidal etc. The importance of the effective usage and utilization of the natural resources are the current focus among scientific community. One of the abundantly available energy resource among all the natural resource is solar energy. Nowadays, Phase Change Materials (PCM) are used for storing the heat energy in the heaters to get efficient system. The function of solar water heater is to heat the water and supply the hot water during day time from the storage tank. But, the PCM installed solar water heater stores the heat energy during day time and supply the hot water even at night time for domestic purposes. Several experiments were conducted to optimize the developed system to get better output. Aluminium Oxide nano fillers are used to find the energy storing capacity and compared the results with and without nanofiller. From the obtained results, PCM absorbs more the heat energy and release the heat for longer duration. The nanofiller also improved the water temperature of 33% more than other commercial water heaters.
