通过对福州某舞厅的CO2、CO、照度、噪声、细菌总数、微小气候及通风等指标的监测探讨其相互间的关系和临场者的主观感觉反应。在未充分通风的舞厅中CO2浓度平均为0.158%;最高达0.195%,临场者感觉空气不良占70%。有充分通风的厅内CO2浓度平均为0.109%,最高为0.135%,感到空气不良的占54%。由于风机运转使厅内噪声超过85dB(A)的标准。CO2浓度、温度与场内累计活动人时数呈直线相关,可认为舞厅空气污染主要来源是场内活动的人;CO和细菌总数则无相关,CO主要来源于场内吸烟。
Through the monitoring of some dance halls in Fuzhou, CO2, CO, illumination, noise, total bacteria, micro-climate and ventilation indicators to explore their mutual relations and the presence of subjective sensory responses. The CO2 concentration in the under-ventilated ballroom averaged 0.158%, up to 0.195%, and the presence of air was felt to be 70%. The adequately ventilated hall had an average CO2 concentration of 0.109%, a maximum of 0.135%, and a 54% feeling of poor air quality. Due to fan operation hall noise exceeds 85dB (A) standard. CO2 concentration and temperature were linearly related to the accumulated activity hours in the field. The main source of air pollution in the ballroom could be considered as the active person in the field. There was no correlation between the CO and the total number of bacteria. The CO mainly came from the indoor smoking.
