EXPERIMENTAL STUDY OF SOLAR WATER HEATING SYSTEM

Renewable energy sources are the sources which can recreate by itself, there are many renewable energy sources are available on the earth like solar energy, tidal energy, win energy…etc but out of them solar energy is most widely used energy for different purpose. It is also a most emerging energy source not only for India but for all over world. Solar energy is used in different fields also for heating water so now a days, plenty of hot water is used for domestic, commercial and industrial purposes. Various resources i.e. coal, diesel, gas etc., are used to heat water and sometimes for steam production. Solar energy is the main alternative to replace the conventional energy sources. The solar thermal water heating system is the technology to harness the plenty amount of free available solar thermal energy. The solar thermal system is designed to meet the energy demands. The size of the systems depends on availability of solar radiation, temperature requirement of customer, geographical condition and arrangement of the solar system, etc. Therefore, it is necessary to design the solar water heating system as per above parameters. The presented work focuses on the construction, arrangement, testing and evaluation of the performance of a solar water heater system. To do so an experimental investigation is done with the help of rising tubes firstly it is done with 3 riser tubes and same procedure is repeated with 6, 7 and 10 riser tubes. The performance of solar water heater is analogized from some parameters like outlet temperature, collector efficiency, solar radiation and daily temperature.
