Solar Water Heater from plastic Bottles and Beverage carton

Abstract

A solar water heater design made from plastic bottles of Pepsi or Miranda. And plastic pipes run up the center of each row of bottles. These bottles act as glazing and also hold reflectors made from beverage cartons. The research aims to take advantage of things that exist around us and are dedicated to using them for once, instead of throwing them think that the benefit from them in the manufacture of solar-powered equipment suitable for domestic hot water. In summer (April), the solar heater heats the water to 52ºC, But in winter, the temperature of cold water in the tank of the house, is around 16ºC to 18ºC, against 22 to 25ºC in summer, and that is due to the difference between the seasons, in addition to the reduction of solar radiation in winter, the thermal efficiency drops from 52ºC in summer to a maximum of 38ºC in winter, This points to obtain a difference in temperature between the inlet and out let of water.
