Abstract

The invention discloses an indoor air quality control system based on personnel positioning. The control system comprises a light scattering type PM2.5 sensor, a CO2 sensor, a wind speed sensor, a wireless transmission module, a terminal, a microprocessor, a human-computer interaction panel and a mechanical ventilation air volume control module, wherein a building model database and a mechanical ventilation air volume calculation platform are installed on the terminal. The invention further discloses a ventilation calculation method. According to the method, based on personnel positioning, calculation is carried out on the functional zones with different pollution levels by using models, so that the optimal ventilation capacity of each functional area is achieved, unnecessary energy consumption and more pollution caused by blind opening of a whole-area mechanical ventilation system are avoided, good energy-saving and environment-friendly benefits are achieved, and when the outdoor pollution is large, more intelligent ventilation selection is provided for residential users or public building energy managers.

Description

technical field [0001] The invention relates to the field of indoor air quality evaluation and dynamic feedback control, in particular to an indoor air quality control system based on personnel positioning and a ventilation calculation method. Background technique [0002] Due to the advancement of building energy conservation work, the airtightness of buildings is getting higher and higher; at the same time, due to the improvement of people's living standards, more and more building materials and furniture are used indoors, and effective indoor ventilation is particularly important. However, in recent years, the smog in northern winter, outdoor pollution, especially particle pollution have seriously affected the air quality in modern buildings. In order to control the concentration of indoor pollutants, source control and ventilation and purification methods can be adopted to improve. At present, the main ventilation methods include natural ventilation, mechanical ventilati...
