为了提高居室空气质量,选择合理的采暖方式,我们于1991年冬,在哈尔滨、长春、锦西和天津四市对不同采暖方式居室CO浓度进行了观察。 在四个城市中选择有代表性的平房7间,楼房9间。采暖方式有蜂窝煤炉(有烟筒和无烟筒)、烧火墙(地龙)和集中暖气供热三种。每种采暖方式连续观察3天,每天早、中、晚各采样一次,烧蜂窝煤炉者每天观察8小时,每2小时采一次样,3天共获有效
In order to improve the indoor air quality and select a reasonable heating method, we observed the indoor CO concentrations of different heating methods in the winter of 1991 in Harbin, Changchun, Jinxi and Tianjin. Among the four cities, there are 7 representative bungalows and 9 buildings. Heating methods are briquettes furnace (with chimney and smoke-free tube), burning fire wall (Dragon) and central heating heating three. Each heating mode for 3 consecutive days of observation, early, middle and late each sampling, burned briquette stove observed 8 hours a day, once every 2 hours sampling, 3 days effective
