摘要：
Based on analysis of uncertainty, this paper presents grey system theory to handle the "grey" characteristic of IAQ. Grey comprehensive analysis of indoor air quality reveals that we should pay more attention to the air purification and humidity control in the design and maintenance of HVAC. In order to represent grey characteristic of IAQ system, the educed grey IAQ models can identify the variation intervals of key IAQ model parameters that are lack of directly measurable messages in practical Situations. Furthermore, grey assessment is an effective multifactor comprehensive assessment method that can express the integrative influence of contamination indexes on indoor air quality. We Can determine the IAQ grade and make comparison according to the grey incidence matrix R. (c) 2006 Elsevier Ltd. All rights reserved.
