具有空调、净化设施的地下工程,虽然满足了温度、湿度、清洁度和气流速度的要求,但人员在这一环境中生活和工作,不仅感到不舒服,还出现一些不适反应。为此我们进行了地下空间空气负离子化的人体效应观察。一、人员未进驻前,坑道内空气负离子浓度仅为地表空气中的63％;人员进驻后,在清洁式、滤毒式、隔绝式通风条件下,坑道内空气负离子浓度分别为0～330个/厘米~3,0～140个/厘米~3,0个/厘米~3。造成地下空间空气负离子贫乏的主要原因是:(一)外界新鲜空气通过空调风道进入地下空间,会消耗一部分空气离子;(二)空气过滤器也能除掉一部分空
Underground work with air conditioning and decontamination facilities, while meeting the requirements of temperature, humidity, cleanliness and airflow speed, are not only uncomfortable but also uncomfortable for people to live and work in this environment. To this end, we conducted the observation of the human effect of air ionization in underground space. First, the personnel before entering the tunnel negative ion concentration of air only 63% of the surface air; personnel stationed in the clean, filter-type, isolated ventilation conditions, the tunnel air negative ion concentrations were 0 to 330 / Cm ~ 3,0 ~ 140 / cm ~ 3,0 / cm ~ 3. The main reasons causing the negative ions in the air in the underground space are: (1) fresh air from the outside enters the underground space through the air-conditioned air duct and consumes a part of air ions; (2) the air filter can also remove part of the air
