针对采用新风对流方案解决室内空气环境质量时存在的难题,介绍了一种风阻小,采用自动清洗工程空气筛设备,解决了因使用传统滤芯存在的风阻大,须频繁更换滤网的问题。 Aiming at the problems of using fresh air convection scheme to solve the indoor air environmental quality, a kind of small air resistance is introduced. The automatic air cleaning equipment is adopted to solve the problem that the air filter must be replaced frequently due to the large air resistance caused by using the traditional filter.
