Embodiment Construction

[0021] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] Figure 1-3 It is a schematic diagram of the structure and principle of the natural ventilator provided by the present invention. The natural ventilator includes a housing 1, an outdoor rain shield 2, an insect-blocking net 3, an internal air flow channel 21, and an indoor air supply port 10, etc. Described natural ventilator is fixed between window frame and glass by upper fixture 5, lower fixture 12, sealing strip 14, gasket 15 and screw. The outdoor side of the housing is connected with an outdoor rain shield 2 to prevent rainwater from entering the natural ventilator in rainy days. An insect-blocking net 3 is arranged between the bottom of the outdoor rain shield 2 and the natural ventilator housing 1 to prevent insects and birds from entering the room. An elastic curtain 8 and a curtain slot 11 are arranged between the indoor air outlet...

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...
