Indoor air environment quality coordination control system and method based on multi-parameter evaluation

Abstract

The invention discloses an indoor air environment quality coordination control system and method based on multi-parameter evaluation. The system comprises an environment data monitoring system, a computer system and an indoor air environment regulation and control system; the environmental data monitoring system comprises an infrared array sensor, a temperature and humidity sensor, an indoor pollutant sensor and an outdoor pollutant sensor; the indoor air environment regulation and control system comprises an air conditioning system for regulating indoor temperature and humidity, and a purification system and a fresh air system for regulating and controlling indoor pollutant concentration; and the computer system controls the indoor air environment regulation and control system according to the data transmitted by the environment data monitoring system. On the premise that requirements of indoor personnel for indoor environment quality are met, energy waste is reduced to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of air quality detection, in particular to a system and method for coordinated control of indoor air environment quality based on multi-parameter evaluation. Background technique [0002] Traditional air quality detection methods have high labor costs and complex operations. The wide application of indoor environment sensor technology and information processing technology makes real-time monitoring of air quality possible. However, the current indoor air quality monitoring and control system only controls a single pollutant. For example, the maximum limit of formaldehyde's 30-min average value is 0.1mg / m 3 Or TVOC (volatile organic compounds) 8h average maximum concentration limit is 0.6mg / m 3 Or the daily average maximum limit of PM2.5 concentration in the air is 75 μg / m 3 or CO 2 The daily average concentration limit is 1000ppm, etc.; in actual buildings, there is not only one pollutant, but many kinds ...

[0002] Traditional air quality detection methods have high labor costs and complex operations. The wide application of sensor technology and information processing technology in indoor environments makes real-time monitoring of air quality possible.

However, the current indoor air quality monitoring and control system only controls a single pollutant. For example, the maximum limit of formaldehyde's 30-min average value is 0.1mg / m 3 Or TVOC (volatile organic compounds) 8h average maximum concentration limit is 0.6mg / m 3 Or the daily average maximum limit of PM2.5 concentration in the air is 75 μg / m 3 or CO 2 The daily average concentration limit is 1000ppm, etc.; in actual buildings, there is not only one pollutant but many kinds of pollutants coexisting indoors, and the indoor temperature and humidity are also varied; at the same time, the system does not take into account Whether there are people in the room, so there is also a certain amount of energy waste
