通风墙体的通风效果分析与数值模拟

Ventilation Effect Analysis and Numerical Simulation of Ventilating Wall

本文根据新型空心砌块构筑成居住建筑外墙后,空心孔洞上下贯通的特点,提出了利用其中的一个空心孔洞作为通道,利用经常开启的厨房和卫生间的排风机作为动力,对室内进行通风的技术途径,并用CFD手段对某一典型房间的通风效果进行模拟。从模拟结果分析,通风效果良好,可有效解决城乡室内空气环境恶化问题,达到节能的目的。

As the building＇s outer wall consists of hollow blocks, which hollow holes are transfixion, a technical method of indoor ventilation, which uses hollow holes as channel and takes exhaust blower as the power which fi＇equently use in the kitchen and bathroom, was proposed out and carried on the simulation of ventilated effect for a typical room by the CFD method. With the analysis of the simulation result, the effect of ventilation is fine, and the method can solve the question effectively of city and countryside indoor air quality deterioration, which achieves the goal of energy conservation.
