Ventilation Research: A Review of Recent Indoor Air Quality Literature

摘要

Building ventilation and air conditioning systems have traditionally beendesigned and controlled to maintain occupant thermal comfort at acceptable capital and operating costs, an indoor air quality (IAQ) has not been a primary concern. A literature review was conducted to survey and summarize recent and on-going engineering research into building ventilation, air exchange rate, pollutant distribution and dispersion, and other effects of heating, ventilation, and air conditioning (HVAC) systems on IAQ. The ventilation-related engineering literature was divided into seven major categories: (1) pollutant transport to and into the building envelope; (2) air cleaning systems; (3) flow and pollutant dispersion, (4) room and building flow/dispersion research; (5) HVAC/building design, operation, and control strategies; (6) applied microbial research; and (7) building performance. The significance and status of ventilation-related IAQ research was summarized by research category, and research opportunities were identified within each category.
