Carbon, can significantly improve removal efficiency of the high energy particle to VOC, peculiar smell of the free radical excitation layer generation, and deep purifying is empty
Gas.Further, the ozone of electric discharge device generation can also be catalytically decomposed in the platinum palladium chtalyst layer, prevent the ozone of high concentration from causing people
Body injury, can effectively prevent the formation of secondary pollution, improve the safety of central air handling system.
In the fresh air purifying unit 5 of the utility model, adsorbing medium can use active carbon or activated carbon fiber.
Active carbon is a kind of very tiny carbon granule, there is very big surface area, and there are also more tiny hole-hairs in carbon granule
Tubule, this capillary has very strong adsorption capacity, since the surface area of carbon granule is very big, so can sufficiently connect with gaseous impurity
Touching；When gas pollutant encounters capillary, the powerful absorption field of force can be immediately by gas molecule inlet hole around active carbon hole
It is interior, have the function that purify air.Preferably, it is preferable that the adsorption layer is activated carbon adsorption layer, the fresh air purifying unit
5 further include being arranged at the heating wire of activated carbon adsorption layer two sides, or heating wire is arranged inside activated carbon adsorption layer,
Desorption processing is carried out to active carbon with the heat generated using electric calorifie installation, so that active carbon is able to in-situ regeneration, is repeated
It utilizes.
Activated carbon fiber is the carbon fiber-containing through overactivation, certain carbon fiber-containing is passed through high-temperature activation, produces its surface
Raw nanoscale aperture, increases specific surface area, to change its physicochemical characteristic；After carbon fiber-containing high-temperature activation, fiber surface cloth
Full micropore, these micropores play the role of adsorbing smell.Compared with active carbon, activated carbon fiber micropore size is smaller and equal
Even, structure is simpler, and for adsorbing organic gas absorption rate faster, adsorption rate is higher, and is easier to be desorbed.
Preferably, the adsorption layer includes the active carbon fiber felt or activated carbon fiber establishment material of at least two layers tiling, and
And it is provided with heating wire between the active carbon fiber felt or the activated carbon fiber establishment bed of material, enable when being laid with heating wire more
Add uniformly, so that activated carbon fiber adsorption layer desorption is more complete.The utility model takes full advantage of air flow channel to air
It filters the activated carbon fiber in adsorption/desorption clean unit and carries out desorption and regeneration in situ, so that the service life of filter material is substantially prolonged
It is long, significantly reduce use cost.
The full touch screen control of the central integrated form that whole system uses, power dust removing units and fresh air purifying unit are in same control
On device processed, the air quantity of power dust removing units is fixed, user open after be fresh air purifying mode, touch screen real-time display temperature,
Humidity, PM2.5 and VOCs content, user select different mode to adapt to indoor environment as needed, can also open automatic mode,
System is regulated and controled according to indoor air environment by system, automatically switches different mode or obstructed air quantity to keep Interior Space
The cleaning in compression ring border is comfortable, and under sleep pattern, blower low power run while energy-saving noise reduction, guarantees user An Xiangjian
Health breathing and sleep.
After opening bidirectional flow central air handling system, under the action of power dust removing units, outdoor fresh air is from outdoor
Fresh wind port 1 enters system, carries out high efficiency filter, fresh air that treated warp to particulate matter aerosol etc. by power dust removing units 2
It is delivered directly to interior after removing the pernicious gases such as particulate matter aerosol and VOCs by fresh air purifying unit 5, realizes the new of system
Wind conveying and the purification function to particulate matter, reduce indoor carbon dioxide content, promote oxygen content.Meanwhile foul indoor
Air can also enter power dust removing units 2 via indoor exhaust wind mouth 3, directly arrange via power dust removing units 2 and outdoor exhaust outlet 7
Out, the air circulation for forming an indoor and outdoor conveys outdoor ozone after high-efficient purification into interior, will be indoor dirty
Turbid air is expelled directly out interior, guarantees the fresh cleaning of room air.
In the process, fresh air and air draft are by being arranged in progress energy friendship on the heat exchanger in power dust removing units 2
It changes, fresh air is heated or freezed using air draft, to carry out heat or cold recovery, save the energy.The heat exchanger is
Total-heat exchanger or sensible heat exchanger, to be suitable for different operating conditions.
The air of foul indoor passes through clean air after purified into fresh air purifying unit 5 via indoor return air mouth 6
The decontamination cycle for forming a room air into interior is conveyed by indoor air outlet 4, has purified the air of foul indoor.With
The flowing of air, the air for inputting indoor fresh air and foul indoor also can enter system by indoor return air mouth 6, remove
Interior is transported to by indoor air outlet 4 after the pernicious gases such as particulate matter aerosol and VOCs, guarantees the excellent of indoor air environment
It is good.
Power dust removing units are internally provided with blower, primary efficient filter screen and high efficiency particulate air, can pass through in its operation
Pipeline is directly inputted to interior after purifying outdoor air sucking via filter screen.
Inside fresh air purifying unit setting blower, middle high efficiency particulate air, activated carbon fibre strainer and energetic free radical and
The air processors such as multicomponent catalyst, can be by high-efficient purification when ensure that indoor and outdoor air via fresh air purifying unit.
The central air handling system fresh air purifying unit of the utility model uses electrostatic electret, high efficiency filter, active carbon
The technologies such as fibers adsorption and energetic free radical triggering multicomponent catalyst, can not only remove particulate matter aerosol of indoor and outdoor etc.
Pollutant, and the VOCs in room air can be effectively removed, it realizes the high-efficient purification to room air pollution, guarantees room
The air cleaning of interior circulation is comfortable；Power dust removing units in the utility model can be arranged directly after removing outdoor air particulate matter
It is put into indoor dilution indoor carbon dioxide, improves oxygen content, and ensure that a little higher than exhaust air rate of indoor intake, formation
Micro-pressure-difference ensure that the cleaning of room air, and indoor air circulation can also be participated directly in by being input to indoor air, and then dilute
The VOCs in air is released, guarantees that room air cleaning is pure and fresh.
The bidirectional flow central air handling system of the utility model has both room ventilation and indoor and outdoor air purification function, and one
The air of foul indoor can be handled and be carried out indoor circulation utilization by aspect, fresh air purifying unit, can also will be indoor dirty
Turbid air is directly discharged to outdoor；On the other hand, power dust removing units are for the air of outdoor input via fresh air purifying list
After the pernicious gases such as first purifying VOCs in input chamber, guarantees the cleanliness and comfort level that are input to indoor air, dilute dioxy
Change carbon, simultaneously effective solve it is indoor close for a long time brought by air quality be deteriorated, realize the simultaneous of fresh air and purification function
Hold.
