Convex Lens With Transparent Glass Solar Water Heating System

Abstract

Conventional energy solutions are necessary in developing countries as current hot water production methods are becoming hazardous to the environment, economic development and the overall health and wealth of the population. The reason of this research paper is to create a convex lens with transparent glass solar water heater prototype, experimentally analyze the system and predict its characteristics when system exposed to the solar behavior of Bangalore, Karnataka, India. Present design from manufacturer and supplier is plane transparent glass solar water heating system. A user of solar energy minimum because cost of the product. With the merits of small structure, less weight, sharp focal length and minimum cost convex lenses are suitable for concentration of solar radiation and system improvement. The efficiency and optical property of transmitted solar radiation is improved and controlled compared to thick normal glass lenses and the solar radiation tracking accuracy need for convex lens group is less compared to other concentration methods.

Concentrated Solar Flux Assessment of Water Lens Collector

“…The relation is given as f = R/ (n-1). Naveen et al [4] stated that a converging lens type collector has more efficiency as compared to simple solar flat plate collector for heating of water also how higher collector efficiency depends on higher flow rate factor as it promotes higher rate in water chamber and reduction in the capacity of solar water heating system. A similar study by Maheswaran et al [5] reveals that the output performance of the spiral coiled heat transfer fluid receiver tube with a convex lens water heater depends on the intensity of solar radiation, mass flow rates of fluids, and thermos-physical properties of heat transfer fluid.…”
