ABSTRACT
Solar Trombe walls have the ability to passively store and subsequently radiate solar energy into a dwelling. The objective of this project was to investigate the feasibility of using a solar water wall constructed of discarded plastic water bottles to heat and insulate a house in an urban an munity. Initial testing was aimed at determining the heat absorption and radiation properties of different liquids and developing a thermal model of the system. Subsequently, a scale model of a house with a solar water wall was built and temperature variations in the bottles and the inside of the house were measured at various times of the day. This test was repeated using bottles with various types of liquids. The data were used to determine the effectiveness of the wall in the absorption, retention and radiation of heat. A wall of bottles filled with water and black dye proved to be the most effective at absorbing heat during the daytime and radiating it back into the house during the nighttime.
