摘要
以马鞍山市天润发超市为研究对象,分三个时间段对温度、相对湿度、风速、CO2、甲醛、菌落数等参数进行了现场测试,并对顾客和工作人员分别进行了问卷调查。测试结果表明:热舒适性指标PMV-PPD值超出了ISO7730的推荐值;CO2和菌落数的超标率和超标强度为晚上最大、下午次之、早上最小;问卷结果表明,超市空气品质的不满意率较高,但光环境和声环境的满意率较高。
Supermarket Tianrunfa was chosen as studying objective and indoor air environmental parameters such as temperature, relative humidity, velocity, carbon dioxide, formaldehyde, and microorganism were tested by three times. A subjective survey was given to customers and employees about indoor environment by questionnaires. The result shows that the index of thermal comfort PMV-PPD exceeds the suggesting value of standard ISO7730; Over-standard rate and over-standard intensity of carbon dioxide and colony forming units of microorganism is evening maximum, afternoon next and morning minimum. The questionnaires indicate that the indoor air quality has a high dissatisfaction, but illumination and sound have a high satisfaction.
