Intelligent positive pressure fresh air system and air purification method therefor

Abstract

The invention discloses an intelligent positive pressure fresh air system and an air purification method therefor. The system comprises a suction fan, an exhaust fan, an inlet pipeline connected with the suction fan, an exhaust pipeline connected with the exhaust fan, an air filter positioned on the inlet pipeline, and a system controller, wherein the system controller comprises an indoor and outdoor pressure difference sensor and a wireless communication control module; the wireless communication control module is wirelessly connected with the suction fan and the exhaust fan; the rotational speeds of the suction fan and the exhaust fan as well as other indoor exhaust devices are intelligently regulated and controlled by detecting an indoor and outdoor pressure difference to ensure that indoor air is in a stable positive pressure state. According to the system and the air purification method, the indoor space can be guaranteed to be in the stable positive pressure state, and the exchange of indoor and outdoor air is performed through intelligent control while outdoor polluted air is prevented from penetrating the indoor space.

Description

technical field [0001] The invention relates to a fresh air system, which belongs to the technical field of ventilation and air purification, in particular to an intelligent positive pressure fresh air system and a method for purifying the air. Background technique [0002] At present, many homes, factories, workshops, etc. have used indoor fresh air purification systems to provide clean air environment for indoor spaces. The indoor fresh air purification system generally includes an air filter and a fresh air unit. The fresh air unit includes a suction fan and an exhaust fan. The suction fan is used to draw the air filtered by the air filter into the room, and the exhaust fan is used to draw The air in the room is pumped out to the outside to form an air circulation to achieve the purpose of reducing the indoor PM2.5 concentration and purifying the air. [0003] However, from the point of view of the purification effect of this commonly used fresh air purification system, ...

AI Technical Summary

Problems solved by technology

[0003] However, from the point of view of the purification effect of this commonly used fresh air purification system, the purification effect is not uniform and not ideal. Generally, the air quality in the space near the air filter is better than other spaces, and the energy consumption is relatively high.
