Multi-parameter dynamic fresh air control system and method

Abstract

The invention discloses a multi-parameter dynamic fresh air control system and method. The control system comprises a temperature and humidity monitoring unit, a formaldehyde monitoring unit, a carbon dioxide monitoring unit, a data storage and display system, a computing control unit and a fan adjusting unit. The temperature and humidity monitoring unit, the formaldehyde monitoring unit and the carbon dioxide monitoring unit are arranged in a building, and the building is provided with a fan. The temperature and humidity monitoring unit, the formaldehyde monitoring unit and the carbon dioxide monitoring unit send monitoring data to the data storage and display system, building information and target parameters are input into the data storage and display system, the data storage and display system transmits the data to the computing control unit for computing and analysis, the computing control unit sends an instruction to the fan adjusting unit according to a computing result, and the fan adjusting unit adjusts working parameters of the fan. According to the system and method, the indoor pollutant concentration can be predicted, the fresh air volume can be adjusted in real time, and the purposes of energy-saving buildings and healthy buildings are achieved through the more reasonable ventilation quantity.

Description

technical field [0001] The invention relates to the field of indoor environment control, in particular to a multi-parameter dynamic fresh air control system and method. Background technique [0002] The actual measurement results show that the distribution characteristics of typical indoor air pollution parameters of shopping malls will change with time, space, human flow, background value of outdoor pollutants, heat and humidity and other factors. It is necessary to adopt a reasonable fresh air control strategy through Control the changes of the above multiple influencing factors to effectively improve the indoor air quality of public buildings. [0003] At present, most of the building fan control methods are relatively rough, and most of them only use the hot and humid environment as the parameter for fresh air control. However, indoor environment regulation depends largely on fresh air, and it is not enough to use fresh air only to regulate indoor heat and humidity. Th...

Problems solved by technology

[0004] At the same time, the current control method is single, and there are few control methods that comprehensively consider multiple parameters such as temperature, humidity and pollutants, making it difficult to comprehensively improve the indoor environment.

At the same time, although increasing the amount of fresh air can reduce indoor pollutants, excessive fresh air will increase the energy consumption of the system, which does not meet the national requirements for energy conservation, emission reduction, and carbon emission reduction.
