Description
Technical field
This utility model is related to room air and fresh air purifying technical field, and in particular to a kind of to have circularly purifying function
Classroom VMC (Ventilation Mechanical Control System).
Background technology
The economy of China is greatly improved, and the quality of life of people is also greatly improved.With people
The continuous improvement of quality of life and the more convenience of living environment quality detection meanss, also increasingly concern breathing is strong for people
Health, also it is more and more efficient and convenient grasp itself local environment Air Quality.Particularly with classroom because crowd is special
Very, people to the attention rate of Classroom air quality also compared to higher.Crowd density inside classroom is very high, and student group
80% time is spent inside classroom, as air dirt, dust granules, antibacterial, formaldehyde often occurs in crowd massing
And other toxic gas, it is especially in winter and summer, intensive due to crowd, serious stink also occurs in classroom.Institute
Think and solved these problems, indoor air cleaner has obtained very big utilization and popularization inside classroom.
Air purifier uses interior circulation pattern, needs to close the doors and windows when use, so, although indoor
PM2.5Concentration can decline, and indoor abnormal flavour can also be removed.But gas concentration lwevel rapidly can rise, it is understood that classroom environment
Under, densely populated, the yield of carbon dioxide is very high.For this problem, unique solution is exactly to be passed through into the room of classroom
Fresh air required for breathing, discharges indoor air so as to dilute.
This special occasion of classroom is directed in the market, and the depurator for being adopted is indoor air cleaner mostly,
This kind of depurator uses the mode of interior circulation and is circulated purification to indoor air, although to indoor particulate matter, it is different
The problems such as taste, is well solved, but not the problems such as not can solve oxygen deficiency.Or it is complete on market employing
It is VMC (Ventilation Mechanical Control System), low-quality room air is diluted using the fresh air of purified treatment, then the air after dilution is discharged
It is outdoor.Practical situation is, new blower fan currently on the market all for classroom design, classroom the characteristics of be that number is intensive,
And the most of the time of student is all spent inside classroom, human body release pollutant and produce abnormal flavour concentration velocity very,
So according to brand-new blower fan, will expect that preferable air can only increase air output, and the increasing of air quantity can undoubtedly increase machine
The running burden of device.Especially for the with serious pollution cold district such as Jing-jin-ji region, in the form of brand-new blower fan, confession is increased
Warm operation burden, causes different degrees of thermal ataxia.Secondly it is exactly that the wholly fresh air up-front investment showed on market is big, it is right
It is a no small financial burden for school.
