Measurement of the color absorption coefficient of the composition of glass - Colorful water- glass experimentally

Abstract

     Air conditioning systems are the largest energy consumer in buildings, so it is necessary to research the possibility of reducing this load and the construction of low-energy buildings due to the lack of fossil fuels and to obtain a clean environment free of gas emissions . One of the ways to reduce this load is to reduce the solar radiation entering the building through the windows . The thing that prompted energy efficient windows. One type of these windows is the flowing water window, which is a space between two transparent glass panels filled with water. The water is tinted in the composition of this window to increase the absorption of radiation, and increase the amount of heat that we can provide with air conditioning and also provide it for home use of hot water through a heat exchange system. In this research, the amount of heat learned and passing through water windows was transparent and colored, by designing and implementing a device for measuring the color absorption coefficients of a colored water composition in several colors: red, green, blue and transparent. As a result of the measurement, it was found that the red colored water absorbs approximately 60% of the value of the solar radiation passing through it, while green water absorbs approximately 48%, followed by blue with a limit of 40%, then transparent that absorbs approximately 34% of the same value of the solar radiation passing through lesson. This means saving 60% of the air conditioning load coming from the windows when using a red flowing window combination.
