Title    Numerical simulation of air conditioning  ventilation in a fan classroom
Abstract
In order to study the quality of the fan room air environment，the numerical simulation of the air distribution is carried out by CFD method. Based on Reynolds averaged navier-stokes equation and standard k-epslion process fluid calculation principle of turbulence model ,both of them are used in the fan classroom indoor air flow field numerical simulation ,numerical algorithm using Simple algorithm. Through the calculation and post-processing of indoor airflow velocity field、temperature field and density field contours, the deep comparison is used in each field cloud image,A deeper understanding of the characteristics of turbulence in the fan room classroom can be done.The feasibility and accuracy of the flow field in the fan room by numerical simulation are verified. The results show that the indoor temperature of the air conditioning varies significantly, the air conditioning is suitable for the wind speed of about 1m/s, the temperature is about 200C.The parameters of air velocity field in air conditioning room can be calculated by numerical simulation.Fluid numerical simulation technology has important significance for energy saving、environmental protection and improving indoor comfort. 源自!六%维^论*文`网www.lwfree.cn

1.1 课题背景
改革开放以后，我国的经济水平快速提高，人们生活水平也逐步提高。人们在房间室内活动的时间也越来越长，比如办公室办公、室内作业。据有效统计，生活在现代社会人们有70%-90%的时间是房间内度过的。所以，室内生活的舒适、健康综合环境非常重要，其中包括声环境、光环境和室内空气环境。因此，室内空气环境质量对人们身体健康具有非常重要意义。还有，舒适的室内空气环境也有提高室内工作人们的工作效率的作用。 某扇形教室空调通风的数值模拟:http://www.lwfree.cn/gongcheng/20181010/23958.html
