Description
Technical field
The present invention relates to IAQ regulation technology, more particularly to a kind of large public building IAQ is adjusted
Save method and system.
Background technology
Large public building is typically all configured with heating ventilation air-conditioning system, and heating ventilation air-conditioning system generally comprises heating, refrigeration, row
The functions such as wind, fresh air.The IAQ of building is exactly by the dioxy in exhaust blower and Fresh air handling units control room air
Change the content of the pollutants such as carbon, VOC (volatile organic matter), PM2.5, nitrogen dioxide, keep the cleaning of room air.
However as the aggravation of current outdoor air pollution degree, increase fresh air not necessarily can just improve room air
Quality；And strengthen air draft and also easily discharge indoor cold air or heating, increase the energy consumption of heating ventilation air-conditioning system.
In the current existing patent for IAQ, it is substantially for single new wind devices or air cleaning
The control of equipment, such as CN103673223A《A kind of VMC and intelligent control method based on wind pushing air quality early warning》Just
It is the control for each air-conditioner set fresh air valve；CN203687297U《IAQ intelligent controlling device》It is then a kind of
Novel fresh air machine set control device.Therefore, a kind of technology controlled for large public building integrated air mass concentration also has
It is to be developed.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of large public building IAQ tune
Section method, the adjusting method is by the real-time monitoring to Outdoor Air Quality and IAQ, by long-distance centralized control,
The VMC and exhaust system of large public building are effectively managed, architecture indoor air quality is improved, is reduced simultaneously
The waste of the energy.
The present invention provides a kind of large public building IAQ adjusting method, comprises the following steps：
