| 摘 要： | 为了改善贫困地区夏季的通风降温问题,设计了一套简易的节能通风系统。通过实验测试和仿真的方法对不同风速以及不同出口孔径大小条件下的系统降温效果进行研究分析。给出了实验过程中不同进口条件下的系统模型,得到了通风装置的仿真云图以及通风系统的制冷效率。结果表明:在与实验条件基本相同的情况下,模拟数据结果与实验结果接近;在一定风速范围内,风速越大,系统制冷效果越好;节流出口孔径越小,系统降温越明显。

| Abstract: | In order to improve the ventilation cooling problem in the poor areas in summer,a set of simple energy-saving ventilation system was designed.Through the experimental test and simulation method,the cooling effect of the system with different wind speed and outlet aperture size is studied and analyzed.The system model under different inlet conditions is given,and the simulation cloud picture of the ventilation device and the cooling efficiency of the ventilation system are obtained.The results show that:under the same experimental conditions,the trend of simulation data is consistent with the experimental results;in a certain range of wind speed,the greater the wind speed,the better the cooling effect of the system;the smaller the orifice diameter of throttle outlet,the more obvious the cooling effect of the system. |
