碩士 === 景文科技大學 === 環境與物業管理系碩士班 === 103 === The main activities of daily indoor public places, mostly stores, department stores, hospitals and other places mainly in public places, to the more sensitive the medical field belongs in public places, this study of indoor air quality by announcement detection methods, sorting out medical the place features indoor and outdoor pollution. According to the results, the indoor air quality test results in the bulletin to carbon dioxide, bacteria, formaldehyde, PM10 as the main pollutants, carbon dioxide concentration peaks hospital three times fall from 10 am to 12:00 am, 4 pm to 6 pm for the main exceeding the time, because people mainly primary doctor periods; PM10 peak time off at 6 am to 8 am, mainly due to work (school) due to the impact, the front of the rest of the period was due to excessive hospital and out the door to the main lane and taxi row ban affected area, the restaurant industry is also part of the surrounding environment one of its sources of PM10; bacterial part is one of the major sources of pollution hospitals, two hospitals figures were 1705 CFU / m3 and 3760 CFU / m3, show the hospital bacteria are still excessive doubts, should be relevant ways to improve. According to the concentration of carbon dioxide, air conditioning outside air damper opening and closing of the correlation judgment, with the number of the amount of carbon dioxide into positive growth, and the other to the air conditioning outside air damper open and close a result, outside air damper enabled pen outside air damper is closed, reducing the rate of carbon dioxide can be reduced 2.75% ~ 21.3%, relative space to accommodate the number will increase by 26% to 63%, indicating that ventilation and carbon dioxide concentration relative relationship. This study suggests ventilation equipment should be regular maintenance, but in the indoor environment can be adjusted back outlet configuration, the door to increase air curtain, adjust clinic arranged between the dispersion flow, management units should work together to assist with the works and other related departments, in order to ensure the safety of people in the indoor environment.
