居住建筑门窗开启对自然通风特性影响的数值研究
Numerical research on natural ventilation properties affected by opening doors and windows of residential buildings
摘要:
利用Airpak软件,在非供暖空调环境下,研究了最常见的平开门和推拉窗不同开启组合方式下的流量系数,定量分析了风压通风中多开口模型的流量系数。搭建了模拟实验平台,利用多区域网络模型对实际房间通风量进行了模拟计算,发现通过改变门窗的开度能够改变有效通风面积,影响房间的自然通风量。利用DeST-h软件模拟分析了门窗不同开启模式对空调能耗的影响。
Abstract:
In an environment without heating and cooling, studies the flow coefficients under the different opening combinations of the common side hung doors and sliding windows using Airpak software. Analyses the flow coefficients of multiple opening models in the wind pressed ventilation quantitatively. Builds a simulation platform, simulates and calculates the ventilation rate of a real room using multi-zone network model, and finds that changing the opening degree of doors and windows can change the effective ventilation area and affect the natural ventilation rate. Simulates and analyses the impact of the different opening combinations of doors and windows on air conditioning energy consumption by DeST-h software.
