由于教室人员密集,通风非常重要,自然通风与机械通风相结合的混合通风是一种适合于教室的通风方式,而太阳能烟囱可以提高自然通风的热压作用。本文对太阳能烟囱辅助教室混合通风进行了研究,采用模型实验和数值模拟的方法对室内热源强度、机械送风口位置、机械送风速度和太阳能烟囱辐射强度对教室内空气温度的影响进行了讨论,分析了太阳能辅助教室混合通风的室内空气温度分布特征。
Due to the concentration of classrooms, ventilation is very important. The combination of natural ventilation and mechanical ventilation is a suitable ventilation method in the classroom. The solar chimney can enhance the natural ventilation and hot pressing effect. In this paper, the study of mixed ventilation in the auxiliary classroom with solar chimney is carried out. The influence of the indoor heat source intensity, the position of the mechanical ventilation outlet, the mechanical blowing velocity and the radiant intensity of the solar chimney on the indoor air temperature are discussed by means of model experiment and numerical simulation. The temperature distribution characteristics of indoor air with mixed ventilation of solar assisted classroom are analyzed.
