倾斜式太阳能烟囱强化自然通风理论研究
Theoretical Study on the Enhancement of Natural Ventilation using Inclined Solar Chimney
摘要
Abstract
Solar energy increases the air temperature inside solar chimney.As a result of the difference in air density between the inside and outside of the chimney,natural ventilation can be induced.A mathematical model of inclined solar chimney was proposed based on conservation of mass and energy in order to predict the air flow rate inside the chimney.The relative error be-tween the calculation results and the datareported in literature is compared.The influence of length,width,depth and tilt angle on the airflow rate was discussed.The air flow rate of inclined solar chimney with an inclination angle of 50°used in Urumqi was cal-culated and is 11.52% higher than that of vertical solar chimney at otherwise identical conditions and is a potential natural venti-lation method.关键词
