摘　　要：建立了带有太阳能强迫通风双层窗房间的传热模型,对带有强迫型通风窗的房间进行了稳态模拟,得出双层玻璃中间空气层的温度分布与速度分布。由温度分布可知空气层中温度最高点位于空气层的底部,横向温度梯度由内向外,最高温度出现在外侧的吸热玻璃,最低温度为内侧的透明玻璃,温差约为5℃;由速度分布可知,速度最大值出现在进风口的上部,可以达到9.02 m/s,出风口与空气层的中间部位速度大小与方向基本均匀,出风口的气流平均速度为0.89 m/s。该模型可为通风窗的优化提供一定的理论依据。The heat transfer model of room with solar forced ventilation double-layer window is established in this paper,and the steady-state simulation of the room with forced ventilation window is carried out,especially the temperature distribution and velocity distribution of the middle air layer of double-layer glass.The results show that the highest temperature point in the air layer is located at the bottom of the air layer,the transverse temperature gradient is from the inside to the outside,the highest temperature appears in the outside of the absorbing glass,the lowest temperature is the inside of the transparent glass,and the temperature difference is about 5℃;according to the velocity distribution,the maximum velocity appears in the small range of the air inlet,which can reach 9.02 m/s,and the velocity between the air outlet and the air layer is uniform.The average velocity of air flow at the air outlet is 0.89 m/s.The model can provide a theoretical basis for the optimization of ventilation window.
