利用空心砌块构筑通风墙体的效果分析与模拟

Effect Analysis and Simulation of the Ventilating Wall Consisted of Hollow Blocks

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, the hollow hole is of transfixion. According to the characteristic, a technical method of indoor ventilation is proposed, which uses a hollow hole as channel and takes exhaust blower of the kitchen and bathroom of frequent using as the power, then the simulation of ventilated effect for a typical room by CFD method is carried on. The analysis result of the simulation shows that the effect of ventilation is fine, the question of city and countryside indoor air quality deterioration can be solved effectively by the method, and the goal of energy conservation will be achieved.
