采用热脱附/气相色谱-质谱联用方法对两套新装修房(完工2个月和4个月)进行通风、封闭1h、连续使用家用空调5 h 3种状态下总挥发性有机物TVOC进行检测。结果显示完工2个月的新装修房间封闭1 h TVOC含量比通风状态增加5倍,而连续开启家用空调5 h后室内TVOC含量比通风状态增加7.9倍;完工4个月的新装修房封闭房间1 h TVOC含量比通风状态增加0.5倍,而连续开启家用空调5 h后室内TVOC含量比通风状态增加2.5倍;污染程度不同的房间在使用空调后TVOC含量也有不同的变化。
採用熱脫附/氣相色譜-質譜聯用方法對兩套新裝脩房(完工2箇月和4箇月)進行通風、封閉1h、連續使用傢用空調5 h 3種狀態下總揮髮性有機物TVOC進行檢測。結果顯示完工2箇月的新裝脩房間封閉1 h TVOC含量比通風狀態增加5倍,而連續開啟傢用空調5 h後室內TVOC含量比通風狀態增加7.9倍;完工4箇月的新裝脩房封閉房間1 h TVOC含量比通風狀態增加0.5倍,而連續開啟傢用空調5 h後室內TVOC含量比通風狀態增加2.5倍;汙染程度不同的房間在使用空調後TVOC含量也有不同的變化。
채용열탈부/기상색보-질보련용방법대량투신장수방(완공2개월화4개월)진행통풍、봉폐1h、련속사용가용공조5 h 3충상태하총휘발성유궤물TVOC진행검측。결과현시완공2개월적신장수방간봉폐1 h TVOC함량비통풍상태증가5배,이련속개계가용공조5 h후실내TVOC함량비통풍상태증가7.9배;완공4개월적신장수방봉폐방간1 h TVOC함량비통풍상태증가0.5배,이련속개계가용공조5 h후실내TVOC함량비통풍상태증가2.5배;오염정도불동적방간재사용공조후TVOC함량야유불동적변화。
Two sets of newly renovated houses completed 2 months and 4 months were selected to detect the total volatile organic compounds (TVOC) in it by TD-GC-MS method in three states such as ventilation, closing 1h and using continuously household air conditioner for 5 h. The result showed that TVOC content in the one-hour-closed room increased five times than that in the ventilation condition, while TVOC content in continuous use of household air conditioner 5 h increased 7.9 times than it. In the newly renovated house completed 4 months, TVOC content in the one-hour-closed room increased 0.5 times than that in ventilation, while TVOC content in the continuous use of household air conditioner 5 h increased 2.5 times than it in ventilation. TVOC contents in different pollution degree rooms had different changes after using air conditioner.
