Problems solved by technology

However, for air quality monitoring in practical applications, it is unrealistic not to consider human factors. If the amount of carbon dioxide exhaled by the human body is ignored value, it will bring larger errors to the calculation results, thus affecting the final indoor air quality assessment and analysis

Abstract

The invention discloses a method for evaluating indoor air quality and a system for monitoring and analyzing indoor air quality. The method comprises the following steps of: monitoring environmental data in an enclosed room; computing mean square deviations between carbon dioxide concentration values measured in real time within a preset period of time and carbon dioxide concentration values at the same moments computed with a formula 1 under the condition of the value of a ventilation rate Q selected within a preset range; determining the value of a ventilation rate Q' which corresponds to a minimum mean square deviation in the computed mean square deviations as a ventilation rate Q in the enclosed room; computing the intensities F of polluting sources which produce polluting components based on the determined ventilation rate Q and the concentrations of the polluting components contained in monitored pollutants; and analyzing the indoor environment based on the monitored environmental data and the computed intensities of the polluting sources. By adopting the method and the system, the concentrations of a plurality of polluting sources in the indoor environment can be monitored in real time, and the air quality can be evaluated and analyzed according to monitoring data.

Description

technical field [0001] The invention belongs to the technical field of environmental quality monitoring, and in particular relates to an indoor air quality evaluation method and an indoor air quality monitoring and analysis system. Background technique [0002] Air pollution often occurs in modern buildings, which endangers human health and causes various diseases such as: Sick Building Syndrome (SBS), Building-Related Illness (BRI), Multiple Chemical Contaminant Allergies (MCS), etc. In recent years, the cases of indoor air pollution in our country have been increasing, and serious indoor environmental pollution has caused huge economic losses to the society. In view of the fact that indoor air pollution is becoming increasingly serious and the types of pollution are complex, a real-time monitoring system that can monitor multiple indicators of the current indoor pollution situation at the same time is urgently needed, and can accurately process and analyze the monitored da...
