A method for monitoring indoor air pollution and ventilation control

Abstract

The invention provides a method for monitoring indoor air pollution and controlling air exchange. The method is applicable to a ventilation system comprising at least two sensors, a signal processing module and an air exchange control module, and takes a time T as a detection period to circularly detect the ventilation system. The method comprises the following steps: acquiring sensing data in the first detection period, transmitting the acquired sensing data to the signal processing module to process the sensing data, obtaining a first air pollution scale value, judging the indoor air condition, obtaining a first air exchange amount to exchange air at the first air exchange volume; acquiring sensing data in the Nth detection period, transmitting the acquired sensing data to the signal processing module to process sensing data, obtaining the Nth air pollution scale value, judging whether the air pollutant concentration is reduced or not, obtaining Nth air exchange volume to exchange air at the Nth air exchange volume, and circularly executing the Nth+1 detection period. The method can monitor the indoor air pollution condition comprehensively, automatically adjust the air exchange volume in time, and reduce the air pollutant diffusion.

Description

technical field [0001] The invention belongs to the field of indoor environment monitoring, and relates to a method for monitoring air and controlling ventilation, in particular to a method for monitoring indoor air pollution and controlling ventilation. Background technique [0002] A large number of research investigations have shown that indoor air pollution is usually 2 to 5 times that of outdoor air, and considering that most urban population spends more than 70% of their time indoors every day, the harm caused by indoor air pollution is more significant. The World Health Organization has listed indoor air pollution as one of the top ten threats to human health. [0003] Ventilation is the most effective and economical means to reduce indoor air pollution. For ordinary families, the use of natural air flow ventilation can meet the requirements, but in some special indoor places, such as: smoking rooms, painting workshops, chemical laboratories, etc., ventilation device...
