Description
Technical field
The invention belongs to air purification fields, are related to fresh air system, especially a kind of fresh air system for having both fire-fighting function
Control method.
Background technique
Fresh air system control technology is by outdoor air by primarily efficient filter, high efficiency filter, electrostatic precipitation and activity
Outdoor oxygen-enriched air filtration is fallen pm10, pm2.5 particle therein and other harmful substances by the filtering approach such as charcoal absorption
It is transported to interior.Simultaneously by foul indoor, high CO2Concentration, the air containing harmful substances such as formaldehyde be discharged to outdoor.It is logical
It crosses microcontroller to carry out the acquisition of sensing data and adjust air quantity, plays the work that indoor and outdoor air constantly exchanges
With.With the development of technology of Internet of things, this Xingfeng capsule system can easily be linked into the system platform of smart home.
This Xingfeng capsule system also has the structure system of oneself simultaneously, combines cloud platform and mobile terminal, realizes mobile whole
End real time monitoring and the function of cloud platform data statistics.
Current industry fresh air product is relatively more, but main working method is broadly divided into three kinds:
1) intelligent work mode
As long as work is working as user in the uncomprehending situation of current indoor air index, equipment can be arranged in the work
Under mode.Equipment is under the working method, by acquiring such as PM2.5, CO2, formaldehyde and VOC etc. sensing datas automatic
With air quantity gear.But equipment is endlessly to indoor input fresh air, only air volume is different.Also can simultaneously
Constantly to outdoor carry out air draft.Guarantee indoor micro-positive pressure.
2) manual work mode
If user thinks that oneself adjusts air quantity, it is necessary to will be under equipment setting to the working method.Realization is manually adjusted
Air quantity.Such case is suitable for user and the case where being turned up or turning down air quantity is known quite well or needed to indoor control environment
Under.
3) sleep operation mode
When user needs night's rest, directly equipment setting can be arrived under the working method.Equipment is in the working method
Under slowly run with low noise, low air quantity.Guarantee a home from home of oxygen-enriched low carbon dioxide during user rests.
Three of the above working method, in the case where the abnormal conditions such as fire occur, machinery equipment can be constantly new to indoor injection
Wind increases the sprawling of fire behavior.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art places, on the basis of traditional fresh air system, in conjunction with
The fire-fighting theory of fire prevention, Smoke prevention provides one kind in the case where there is fire behavior, inhibits the injection of oxygen, increases smoke evacuation dynamics
Method.
The technical proposal for solving the technical problem of the invention is:
A kind of fresh air system control method having both fire-fighting function, in the PM2.5 sensor and/or CO of fresh air system2It passes
Fire-fighting threshold values is set on sensor, when detecting PM2.5 and/or CO in air2When concentration reaches the fire-fighting threshold values, fresh air is closed
Inlet valve, while increasing exhaust power.
Moreover, the PM2.5 sensor and/or CO2The fire-fighting threshold values of sensor is set according to fire protection criteria.
Moreover, the fire-fighting threshold values of the PM2.5 sensor is 500 or more.
Moreover, when detecting PM2.5 and/or CO in air2It, will be on the abnormal data when concentration reaches the fire-fighting threshold values
Cloud server is passed to, cloud server transmits that data to user mobile phone, background terminal, and report can be shown on user mobile phone
Alert signal.
The advantages and positive effects of the present invention are:
1, when detecting that smokescope is more than threshold value set by fire engineering, the defeated of new wind devices cutting fresh air is controlled
Enter, increasing exhaust power.The injection for cutting off outdoor oxygen is played, the purpose of the discharge of indoor smog is increased.Oxygen is not indoors
In the case where foot, the sprawling of fire behavior restrained effectively, striven for valuable time for fire-fighting and rescue.
2, the present invention utilizes the PM2.5 sensor and/or CO in traditional Xingfeng capsule system2Sensor passes through setting
Threshold values assigns its fire-fighting function, and without adding other sensors, scrap build is at low cost, practical.
Detailed description of the invention
Fig. 1 is the flow chart of this method.
Specific embodiment
The invention will be further described with reference to the accompanying drawing and by specific embodiment, and following embodiment is descriptive
, it is not restrictive, this does not limit the scope of protection of the present invention.
Embodiment
By taking the operation of blower automatic mode as an example
Blower totally 2 (fresh-air fan and each one of exhaust fan), 3 grades of Boiler pressure controls, according to Air Quality
(PM2.5 and CO2And the concentration of TVOC) adjust automatically air quantity；
It is high-grade: as PM2.5 >=75ug/m3Or CO2When >=1150ppm, the operation of blower top grade；
Middle-grade: as 55≤PM2.5 < 75ug/m3Or 950≤CO2When < 1150ppm or TVOC=0.6, blower middle-grade fortune
Row；
It is low-grade: as 35≤PM2.5 < 55ug/m3Or 600≤CO2When < 950ppm or TVOC=0.4, blower underdrive operating；
It shuts down: as PM2.5 < 35ug/m3And CO2< 600ppm and when TVOC=0.1, fresh-air fan and exhaust fan stop
Operation；
Fire-fighting: as PM2.5 > 500ug/m3Cut off fresh air input, increasing exhaust power to maximum power.
1. as PM2.5, TVOC and CO2When real-time detector data any value reaches high tap position concentration range, blower is directly complete
At upshift operation；
2. as PM2.5, TVOC and CO2When real-time detector data any value reaches low-grade location concentration range, 5min is needed to wait for
It downshifts later, during timing 5min, any moment is in the gear that have to be dropped to, then timing clear operation waits lower a period of time
Triggering downshift is carved, is then counted again.If continuing 5min to downshift all in request, downshift operation is completed after 5min.If going out
Existing PM value is lower than 5 values of gear to be dropped to or CO2It is worth lower than 50, it is desirable that downshift operation immediately.
3. machine is automatically stopped work when the actually detected both less than low-grade minimum to three item datas.Work as real-time detection
When any one of data is higher than low-grade setting value, machine is again started up.ON/OFF switch is pressed in "Off" state, machine shutdown.
4. fresh-air fan stops working, and exhaust fan reaches in automatic mode, when PM2.5 is more than the threshold value 500 of setting
To peak power output.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, under the premise of not departing from inventive concept, various modifications and improvements can be made, these belong to protection of the invention
Range.
