Description
Technical field
The utility model belongs to air purification field more particularly to a kind of fresh air system of console mode high-efficient purification.
Background technology
Fresh air system is made of a set of ventilating fan, pipeline and some attachmentes that can take a breath and purify air
Outdoor live gas by filtering, purification, is pipelined to interior, simultaneously by independent air processing system, ventilating fan
The air of foul indoor is discharged outdoor.
Haze weather is a kind of atmosphere pollution state, and haze is exceeded to various suspended particulate substance contents in air general
Statement, especially PM2.5 (equivalent aerodynamic diameter is less than or equal to 2.5 microns of particulate matter) is considered as causing haze sky
" arch-criminal " of gas.With the deterioration of air quality, thick weather phenomenon increases, and harm aggravates.Due to tiny powder in haze
The floating particle object diameter of shape by respiratory system generally at 0.01 micron hereinafter, directly can enter bronchus or even lung.Institute
With, haze influence it is maximum be exactly people respiratory system, caused by disease be concentrated mainly on breathing problem, cranial vascular disease, nose
In the diseases such as chamber inflammation.Meanwhile when haze weather, air pressure reduction, Inhalable Particulate abruptly increase, air flow property are poor,
Harmful bacteria and virus slow to what surrounding was spread, cause virus concentration in air to increase, the risk of transmission is very high.
Haze causes air quality to decline, and has very big harm to people.

Reach quite high concentration sometimes.It is one so designing and developing the system for eliminating the pollutant in indoor air
Urgent problem to be solved.But current fresh air system on the market only has outdoor air feeding interior, it will be indoor muddy
The outdoor function of air discharge, cannot effectively purify the air of a room, although a kind of indoor air cleaner occurred on the market
Indoor PM2.5 can be effectively removed, is purified the air of a room.But existing air purifier, which can only carry out room air, to follow
Ring, for a long time, oxygen content is reduced in closed room air, other toxic gases such as carbon dioxide increase, air
Become muddy, this, which is air purifier, to purify.Especially with the exacerbation of haze, indoor pollutant increasing but will be aggravated
More problems.
Indoors, equipment will produce certain noise to fresh air system on the market when running, and cause to give birth to for installation mostly simultaneously
Inconvenience in work.
