Water Heating System Using Solar Concentration and Temperature Feedback: A Aost Efficient Approach

Abstract

Hot water is a very essential component to be utilized for residential, business and mechanical purposes. Different assets i.e. coal, diesel, gas, power and so forth, are utilized to warm water, which is very costly process. Sunlight based water warming framework is one of them and more affordable than others. The extent of the frameworks relies upon accessibility of sun-oriented radiation, temperature necessity of client, topographical condition and game plan of the nearby planetary group and so forth. The primary target of this research was converting the solar energy into thermal energy and controlling the desired hot water temperature for water heating purposes. In this paper, closed loop solar water heating system was used. A solenoid valve was used to control the supply water which will be going to the user. To control the hot water, temperature feedback control system was used which can sense the water temperature using temperature sensor. The temperature of condenser was sensed by using LM35 temperature sensor also. To increase the efficiency of the collector an additional dual-axis concentrator was used. The research was successful to increase water temperature up to 19°C and stable it.
