Passive Solar Energy for Heating Buildings

Abstract

This research includes the construction of a mathematical model for thermal equilibrium equations in different sections of wall collect and stores heat (Tromp Wall) that which consider one of the most important passive solar heating system.Differential equilibrium equations of this model were solved by using numerical solution based on control volume method with the help of computer program which has been developed for this purpose .In order to study the effect of some design parameters, such as thickness of wall and type of constructed   materials, the solution has been applied for five types of this wall. Three of them which are made of concrete   with different   thicknesses 10 cm, 20 cm and 30 cm, and the two other are made of brick and stone with 20 cm thickness .The results of the solution that has been reached showed clearly that the wall made of concrete with 20 cm thickness is the best among these walls in term of collection, storage and transfer of heat to the space to be warmed.
