Fresh air purification system

Abstract

The invention relates to a fresh air purification system. The fresh air purification system comprises an air feeding device, an air exhausting device, an air duct, an air filtering device and a fresh air device. The air feeding device is provided with an air inlet and an axial flow fan and used for introducing air into the fresh air purification system. The air exhausting device is provided with an air outlet and a centrifugal fan and used for exhausting the air from the fresh air purification system. The air duct connects the air feeding device with the air exhausting device and is used for guiding the air between the air feeding device and the air exhausting device. The air filtering device is arranged in the air duct and used for filtering the air. The fresh air device is arranged opposite to the air inlet and comprises a multipurpose air opening communicating with the outdoor and an air volume regulation plate rotationally arranged in the multipurpose air opening. The fresh air purification system can lower noise, dissipate heat and flexibly adjust the fresh air volume between absence of fresh air and pure fresh air.

Description

technical field [0001] The present invention generally relates to the field of air purification, in particular to a fresh air air purification system. Background technique [0002] Today's air purification systems often use multiple filter devices, such as multi-layer filter paper, to filter out various harmful components in the air, such as particulate matter, odor molecules, and the like. However, due to the increase of air resistance caused by setting too many filter devices, such air systems often use high-power fans to achieve the desired air filtration speed. However, this creates a problem that a high-power fan inevitably produces noise of eg up to 55-60 decibels and may cause problems in heat dissipation. [0003] In addition, the existing air purification systems are generally placed indoors and not communicated with the outdoors, so fresh air cannot be introduced. However, the existing air circulation system with fresh air function cannot flexibly adjust the fres...

Problems solved by technology

However, due to the increase of wind resistance caused by setting too many filter devices, such air systems often use high-power fans to achieve the desired air filtration speed

However, this creates the problem that high powered fans inevitably generate noise of eg up to 55-60 decibels and may cause problems in terms of heat dissipation

[0003] In addition, the existing air purification system is generally placed indoors and not connected to the outdoors, so fresh air cannot be introduced.

However, the existing air circulation system with fresh air function cannot flexibly adjust the fresh air volume between no fresh air and 100% fresh air
