新风净化设施检测研究

Study of Test Method for Make-up Air Facilities

新风净化设施在传统机械通风的基础上,增加了空气净化功能,可以通过内循环重复净化以及把外部空气净化送入室内并排出室内污浊空气以达到空气净化效果。针对新风净化设施不同工作方式提出了统一的数学模型,通过数学分析得出评价新风净化设施的关键参数,提出了名义洁净空气量和总通风量概念及相关检测方法。

On the basis of traditional mechanical ventilation,the Make-up Air Facilities can not only supply air purification function,but also reinforce effect of room ventilation.The air purification effect by repeatedly purifying the internal circulation and purifying the external air into the room and discharging the indoor polluted air.This paper presents a common mathematical model for different working pattern of Make-up Air Facilities.Through mathematical analysis,the key parameters for Make-up Air Facilities are obtained.This paper offers the concept of claimed clean air delivery rate and total ventilation airflow volume,which is used in evaluating capability of Make-up Air Facilities.
