IMPACT OF INDOOR TEMPERATURE AND FRESH AIR RATE ON EVALUATION OF PERCEPTION OF INDOOR AIR QUALITY STUDIES IN A WIDE TEMPERATURE RANGE

摘要

The experience was carried out in the conditions of fresh air rate with 14 m3/h·per and 48 m3/h·per and indoor temperature in the range 14-31.5°C and 50±3% relative humidity and Wind speed < 0.15 m/s. The aim is to study the impact of indoor temperature on evaluation of Perception of indoor air quality in an indoors common and wide temperature range. There are four subjective evaluation index of perceived air quality in the paper, including odour perception, air fresh perception, air depressing perception and the acceptability of air. Through analysis of the test data and the statistics, the results indicated that the evaluation of fresh air perception, acceptability of air and air depressing perception are all improved with the decreases of indoor temperature at above situation. However, there is no distinct regularity on the evaluation of odour perception. The three index including air freshness perception, air depressing perception and acceptability of air are influenced weakly by temperature for the large fresh air rate but influenced strongly for small fresh air rate.
