A Study of the Effectiveness of Fans in School Buildings Using CFD Simulations
With the rapid development of Chinese education, more and more school buildings were established in recent years. Unlike commercial buildings, most school buildings in China are designed for natural ventilation to fulfill thermal comfort. In hot weather, due to too many students having classes at same time, the thermal conditions in classrooms were so poor to affect students learning, especially for large lecture rooms. Therefore, it is important to study the natural ventilation of school buildings and to explore effective means to improve the thermal comfort conditions of school buildings. This study was conducted using Fluent CFD software to improve the ventilation performance in one classroom. The field study was carried to to collect the actual data of boundary conditions for CFD simulation. The CFD approach provided simulation results with different numbers of fans installed in the classroom. In the CFD simulations, the models with fans or without fans were created. By comparing the different cases simulated by Fluent software, it was found that installing fans could improve the ventilation performance in the classroom effectively. It also can be seen from the CFD simulation results that the numbers of the fans and installing positions of the fans can affect the ventilation performance.
