摘要
Abstract
Using natural ventilation technology and utilizing new energy resources are the main energy saving techniques used in modern buildings to improve the indoor thermal environment and to reduce air conditioning energy consumption. The solar chimney is the combination of above two methods, based on the natural ventilation the building. It uses solar radiation as the driving force to help the air flow, and to convert the thermal energy to the kinetic energy of the air. In this paper, the numerical simulation of a solar chimney application in a project is performed. Realizableκ-εturbulence model, discrete-ordinates radiation model and SIMPLEC algorithm are used to calculate and analyse the temperature and air velocity distribution inside the building. By comparing the effect of different building design parameters such as air flow velocity, air intake and outlet areas to elucidate how "chimneys effect" affects the environment inside the building.关键词
