室内空气品质的新定义与新风直接入室方法的实验测试

不能把室内空气品质仅仅认同于一系列污染控制指标，应以人们对空气品质的满意程度来徇空气品质的高低。因此主观评价是判定室内空气品质的主要依据。新风对改善室内空气品质起着比其他因素更为重要的作用。本文着重研究将新风直接送入空调室，并采用独特的方法减少新风对室内温度场的速度场的干扰，室内人员普遍反映室内空气品质极大改善，而未感受到新风的干扰。

Redefinition of IAQ and direct fresh air supply

Indoor air quality(IAQ) is not merely a list of air components.It is the extent to which the people breathing the air are satisfied.Therefore the subjective evaluation should be taken as the yardstick of IAQ. Fresh air plays a very important role for improving IAQ.This paper demonstrates the authors'practices of supplying fresh air directly into air conditioned rooms,and it is turned out that the IAQ is improved greatly without thermal disturbance felt by the occupants.
