Positive-pressure fan ventilation device based on CO2 concentration control and use method thereof

Abstract

The invention discloses an intelligent positive-pressure fan ventilation device based on CO2 concentration control. The device comprises a shell, a turbulence system, a fan system, a filtering systemand a protection system, wherein the protection system, the turbulence system, the fan system and the filtering system are all arranged in the shell, the turbulence system comprises an air turbulenceplate and a spoiler, the fan system is a positive-pressure fan, the positive-pressure fan is arranged between the air turbulence plate and the spoiler, and the protection system is arranged behind thespoiler. The positive-pressure fan ventilation device is a positive-pressure ventilation system and supplies air to the indoor through the outdoor, the turbulence system is arranged on the positive-pressure fan ventilation device and particularly comprises the front step spoiler and a preposed air deflector, and front steps have a high rectifying effect; the front step spoiler is arranged at thefront end of a filtering layer, rectifying is conducted on the incoming flow, and the energy utilization efficiency of a fan is improved; and meanwhile, the air deflector is arranged at the front endof the fan, and the design can effectively adjust the wind direction of the fan.

Description

technical field [0001] The invention relates to the field of ventilation equipment, in particular to a CO-based 2 An intelligent positive pressure fan ventilation device for concentration control and its application method. Background technique [0002] Whether it is study, work or rest, people spend most of their time indoors, and problems such as sick building syndrome (sBS) have become increasingly prominent. With the improvement of living standards, people pay more and more attention to the indoor air quality. At present, manual opening of windows for natural ventilation is the main way to improve indoor air quality. However, in haze weather, outdoor fine particulate matter (PM 2.5 ) into the room through the window, aggravating the pollution of indoor air. Air purifiers are generally used to remove PM 2.5 and formaldehyde and other indoor pollutants, but most household air purifiers do not have a ventilation function, and still cannot effectively improve indoor air...

AI Technical Summary

Problems solved by technology

However, in haze weather, outdoor fine particulate matter (PM 2.5 ) into the room through windows, aggravating indoor air pollution

Air purifiers are generally used to remove PM 2.5 and formaldehyde and other indoor pollutants, but most household air purifiers do not have the function of ventilation, and still cannot effectively improve indoor air quality

In addition, when the indoor air conditioner is running, if the windows are not opened for natural ventilation, the indoor air quality will still deteriorate. If the windows are opened for natural ventilation, energy consumption will increase

Ventilators can be used to achieve the function of ventilation, and some fans have filters to remove indoor PM 2.5 , can improve indoor air quality, but this type of mechanical ventilation system is mainly used in large commercial buildings and some villas, and the cost is high, the installation is complicated, and it is not suitable for ordinary civil buildings, etc.
