民用建筑室内设计新风量研究

Research on design fresh air requirement for civil buildings

基于建筑室内设计新风量理论,比较和分析了国内外新风量标准及其体系的差异,指出近年来国际新风量标准在考虑建材污染及其污染程度、人员适应性、吸烟空间、人员主观满意度、CO2指标等方面有所发展。随着当前室内人员污染、建材污染问题的凸显,需要在污染源特征的反映、标准的针对性、低密人群建筑新风量标准、高密人群建筑新风量标准和其他建筑新风量标准的有条件适用性等5个方面对现行标准进行修订。介绍了GB 50736—2012《民用建筑供暖通风与空气调节设计规范》中对公共建筑、设置新风系统的居住建筑、医院建筑和高密人群建筑等四类建筑的最小新风量的修订。

Compares and analyses the standards of fresh air requirement at home and abroad and their system discrepancy based on design theories of fresh air requirement. The results indicate that some international standards have been developed in consideration of the building material pollution and its intensity, adaptability of occupants, smoking space, subjective satisfaction of occupant,; and CO2 index. Considering increasingly obvious pollution issues caused by occupants and building materials, deems it essential to revise the present standards at home from the five aspects of the reflection of the pollutant source characteristics, pertinence of the standards, fresh air requirement of buildings with low and high occupation density and the conditional applicability of the standards for civil buildings. Presents the revisions of minimum fresh air requirement for public buildings, residential buildings with fresh air systems, hospital buildings and high occupation density buildings in the new standard GB 50736--2012 Code for design of heating ventilation and air conditioning of civil buildings.
