Embodiment 1

[0058] In this embodiment, a method for regulating indoor air quality of a large public building, such as image 3 shown, including the following steps:

[0059] (1) After starting the system, the remote server reads the pre-stored information on the air volume of the fresh air system and the air volume of the exhaust system in each area of ​​a large public building, as well as the upper and lower limits of the concentration of carbon dioxide in the indoor air IN_CO set by the building management personnel. max , IN_CO min , PM2.5 concentration upper and lower limits IN_PM max , IN_PM min , VOC concentration upper and lower limits IN_VOC max , IN_VOC min , the upper and lower limits of PM2.5 concentration in outdoor air OUT_PM max , OUT_PM min , upper limit of sulfur dioxide concentration OUT_SO max , Nitrogen dioxide concentration upper limit OUT_NO max , and the percentage setting value ε that the fresh air volume is more than the exhaust air volume.

Abstract

The invention discloses an indoor air quality adjusting method and system of a large public building. The method comprises the following steps that a remote server reads primary air system air volume and exhaust system air volume information pre-stored in various areas in the large public building, the top and bottom limitation information, set by a building management worker, of the concentration of carbon dioxide, PM2.5 and VOC in indoor air, the top and bottom limitation information, set by the building management worker, of the concentration of PM2.5 in the outdoor air, and the top limitation information, set by the building management worker, of the concentration of sulfur dioxide and nitrogen dioxide in the outdoor air; and the remote server periodically collects data of an indoor air quality monitoring device and data of an outdoor air quality monitoring device, real-time data are compared with the limiting value, and a primary air system and an exhaust system are controlled. According to the indoor air quality adjusting system of the large public building, a primary air device and an exhaust device of the whole building are controlled by the remote server in a centralized manner. Compared with a current system controlled by a single device, the control scale is larger, and the quality of the indoor air of the building can be adjusted from the macroscopic level.

Description

technical field [0001] The invention relates to indoor air quality adjustment technology, in particular to a large public building indoor air quality adjustment method and system. Background technique [0002] Large public buildings are generally equipped with HVAC systems, which generally include functions such as heating, cooling, exhaust, and fresh air. The indoor air quality of buildings relies on exhaust fans and fresh air units to control the content of carbon dioxide, VOC (volatile organic compounds), PM2.5, nitrogen dioxide and other pollutants in the indoor air to keep the indoor air clean. [0003] However, with the increasing degree of outdoor air pollution, increasing fresh air may not necessarily improve the quality of indoor air; increasing exhaust air will also easily discharge indoor cold or warm air, increasing the energy consumption of the HVAC system. [0004] At present, among the existing patents aimed at indoor air quality, they are basically aimed at ...
