某隔离病房通风工程中的角联风路分析
Analysis to diagonal branches in a ventilating and air conditioning project for negative pressure isolation wards
摘要：
以某隔离病房通风空调工程为实例，建立了建筑通风网络模型，针对该工程涉及的所有角联风路进行了判定分析，并仿真模拟了该工程可调节风路阻抗值变化对角联风路风量的影响。结果表明，在隔离病房的通风网络模型中，门窗作为一个风路，通常满足角联风路的条件。通过对角联风路的分析，发现隔离病房空调风系统中风量的一些特点：门窗分支的阻抗变化与空调系统本身风量值无相关性，门窗两侧的压差主要受与之相连的空调风系统的风量的影响。
Abstract：
Takes a ventilating and air conditioning project as an example, establishes the building ventilating network model, judges all the diagonal branches and simulates the effect of the changes of branch resistance to the air volume. The results show that door and window branches are usually the diagonal branches in ventilating network model for isolation wards. Through analysis on diagonal branches, indicates that the air volume of an air conditioning system is irrelevant with the door and window branches resistance, while the main factor influencing pressure difference across the door and window is the air volume of connected air conditioning systems.
