Natural ventilator and real-time indoor air quality monitoring method

Abstract

Disclosed are a natural ventilator and a real-time indoor air quality monitoring method. The natural ventilator comprises a shell, an outdoor rain retaining plate, indoor air supplying outlets, an insect blocking net, regulating handles, an elastic curtain, an indoor air quality monitoring sensor module, a data transmitting module, a data receiving module, a data analyzing and processing module, a data storage module and a display panel. Electrical signals monitored through air quality monitoring sensors arranged indoor are transmitted to the data receiving module through the data transmitting module and then are subjected to digital-to-analogue conversion an analytical processing through the data analyzing and processing module to obtain various of indoor environment parameters and overall indoor fresh air volumes; the data are displayed in real time through the display panel and stored in the data storage module. The natural ventilator has the effect of ventilating while a window is closed, and various indoor environmental indicators and the overall indoor fresh air volumes can be monitored in real time, so that a user is enabled to know indoor environment and ventilation status more visually.

Description

technical field [0001] The invention relates to a natural ventilation facility in a building, in particular to a natural ventilator capable of real-time monitoring of indoor environmental parameters and fresh air volume, and displaying the monitored data, belonging to the technical field of natural ventilation and indoor air quality detection. Background technique [0002] The airtightness of modern buildings is getting stronger and stronger, and many buildings have a serious problem of insufficient fresh air when the windows are closed. 〖Journal of Environment and Health〗,2005,22(1):47-49. Coupled with the extensive use of decoration materials, the phenomenon of various indoor pollutants exceeding the standard is very serious: Liu Ruqing, Du Derong, Cai Chengkeng, etc. published "Indoor Air Pollution Status of Decorated Living Room in Guangzhou and Its Impact on the Health of the Population", 〖 Environmental and Health Journal〗, 2010,27(4):361-361", has a very adverse effe...

AI Technical Summary

Problems solved by technology

However, some patented sensors are directly installed in the middle ventilation channel of the ventilator, and the monitored data is likely to be the situation of the introduced outdoor fresh air, which cannot reflect the actual indoor air quality (application (patent) number: 201210112076.4, a building Door, window and curtain wall sensor control intelligent power ventilation device)

Some still have monitoring and display functions (invention patent application: 201110430253.9, curtain wall forced ventilator), but only stay in the direct display of monitoring data, without further processing of data

Moreover, all current ventilators are basically blank for real-time monitoring and display of fresh air volume, the most important parameter reflecting its ventilation performance, and the display of indoor air quality parameters is not intuitive enough.
