地下KTV包间空气品质调查分析

Investigation and Analysis of Air Quality in Underground KTV Rooms

研究了地下KTV包间这类公共娱乐场所的室内空气品质。在不同季节,对某市3家地下KTV包间的温度、相对湿度、风速、CO2体积分数、氡、可吸入颗粒物和菌落总数进行测试并开展了相关问卷调查。测试及问卷调查结果显示:3家KTV包间室内空气品质均不乐观,1#,2#KTV包间的相对湿度、CO2体积分数、可吸入颗粒物、菌落总数和3#KTV包间的温度、相对湿度、风速均超出相关标准。分析可知,新风量是影响地下KTV包间空气品质的最重要因素。可从合理安排新风量、优化室内气流组织、有效调节室内相对湿度、提高空调系统的过滤性能、减少室内污染源等方面,积极改善地下KTV包间的空气品质。

The air quality in public entertainment places such as underground KTV rooms was studied. Three KTV rooms in a citY were tested about the indoor temperature, relative humidity, wind speed, CO2 concentration, radon, inhalable particles and the total number of colonies in different seasons, and the relevant questionnaire survey was conducted. The results show that air quality of the three KTV rooms is not optimistic, the relative humidity, CO2 concentration, inhalable particles and the total number of colonies of KTV room 1# and 2# as well as the temperature, relative humidity and wind speed of KTV room 3# are beyond the relevant standards. The analysis shows that the fresh air volume is the most important factor to affect the air quality in underground KTV rooms. The air quality can be improved by reasonably arranging fresh air volume, optimizing indoor airflow, regulating effectively indoor relative humidity, improving the filtration performance of air-conditioning system and reducing indoor air pollution sources, etc.
