Centrifugal blower is provided with fresh air channel, fresh air channel sets gradually primarily efficient filter filter screen, anion lotus from section is started
Electric installation, exchange coalescence device, high efficiency filter filter screen.Exchange coalescence device uses four blocks of 30cm × 15cm aluminium sheets as coalescence
Plate.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model.
Fig. 2 is coalescence principle schematic.
Embodiment
As shown in Figure 1-2, aluminium sheet connects 12V50Hz low-voltage ACs respectively, and coalescence is carried out using alternating current.I.e. with electrochondria
When son is by coalescence area, mainly changed motion state by electric field force effect, so as to occur dipole effect with other particle encounters
(when uncharged particle is contacted with charged particle, induce opposite charges, attract each other, so that coalescence), becomes diameter bigger
Particle.Coalescence particle neutralizes the probability increase that other particles collide in vibration processes, so that coalescence effect is more preferably, purification effect
Rate is higher.
Centrifugal blower is provided with return air channel, primarily efficient filter filter screen is provided with air return section entrance.
Primary filter net uses 30cm × 30cm non-woven fabrics primary filter screens, can effectively stop the large-size particles such as hair
Thing, extends high efficiency net service life.
Charge device uses anion generator.Operation principle is：The device is high for exchange by the exchange electric boost of input
Pure negative direct current high voltage is obtained after piezoelectricity, rectifying and wave-filtering, negative direct current high voltage is connected to the release tip of carbon making, profit
High corona is produced with sophisticated high direct voltage, substantial amounts of electronics (e-) is released at high speed, electronics at once can be by the oxygen molecule in air
Catch, so as to generate negative aeroion.
First filter screen 3 and the second filter screen 5 are efficient filter, and using 30cm × 30cm HEPA filter screens, air can pass through,
But tiny particulate can not pass through.For crossing the particulate matter in air filtering；
Such as Fig. 1, by-pass is by total-heat exchanger, for allowing the air by purification not sent directly by total-heat exchanger
Enter interior, work as to tackle under some particular cases, total-heat exchanger is unsatisfactory for use requirement, and (summer outdoor temperature is less than interior
When) or Analyze Efficiency of Total Heat Exchanger it is low, when not using meaning, open by-passing valve to save and extend hardware service life.
Bypass logic such as following table
| Indoor air temperature is higher than outdoor | Indoor air temperature is less than outdoor | Indoor/outdoor temperature-difference is less than 2 DEG C | |
| Summer | Open | Close | Open |
| Winter | Close | Open | Open |
It is controlled in by-pass provided with by-passing valve temperature in use sensor.
With reference to Fig. 1 explanations purification process when by-pass is closed：Fresh air enters clarifier from first efficiency net and fresh air inlet,
And the large-size particles things such as hair dust are filtered by primary filter screen, particulate matter lotus in fresh air is then made at negative ion generating device
Electricity, at coalescence plate, due to alternating electric field influence, charged particle thing is shaken in the electric field, particle diameter is become big, by efficient filter
When remove particulate matter and form clean fresh air, clean fresh air reclaims heat in return air by the board-like air-to-air total heat exchanger of cross-counterflow, then
It is indoor via centrifugal fan and fresh air outlet feeding.Return air enters clarifier by first efficiency net and return air inlet, and by
The large-size particles things such as primary filter screen filtering hair dust, then give heat exchange by the board-like air-to-air total heat exchanger of cross-counterflow
Clean fresh air, is finally sent out outdoor by centrifugal fan and return air outlet.
With reference to Fig. 1 explanations purification process when by-pass is opened：Fresh air enters clarifier from first efficiency net and fresh air inlet,
And the large-size particles things such as hair dust are filtered by primary filter screen, particulate matter lotus in fresh air is then made at negative ion generating device
Electricity, at coalescence plate, due to alternating electric field influence, charged particle thing is shaken in the electric field, particle diameter is become big, by efficient filter
When remove particulate matter and form clean fresh air, clean fresh air directly by by-pass without the board-like air-to-air total heat exchanger of cross-counterflow,
It is indoor via centrifugal fan and fresh air outlet feeding again.Return air enters clarifier by first efficiency net and return air inlet, and
By the primary filter screen filtering large-size particles thing such as hair dust, only then through the board-like air-to-air total heat exchanger of cross-counterflow not exchanged heat
Amount, is finally sent out outdoor by centrifugal fan and return air outlet.
Half straight-through inlet tube 13 is arranged on just between efficiency net and return air inlet 1, the first filter screen 3, half straight-through inlet tube 13
Arrival end be arranged on outside housing 2, the port of export of half straight-through inlet tube 13 is arranged on the centre of the first filter screen 3, straight via half
The distinguished and admirable of logical inlet tube 13 is that half filter formula is distinguished and admirable.
Half straight-through outlet 12 is arranged between the first filter screen 3 and the second filter screen 5, the arrival end of half straight-through outlet 12
The sidepiece of the second filter screen 5 is arranged on, the port of export of half straight-through outlet 12 is arranged on the centre of the second filter screen 5, straight-through via half
The distinguished and admirable of outlet 12 is that half filter formula is distinguished and admirable.
By setting half straight-through inlet tube 13 and half straight-through outlet 12, the two and half filter distinguished and admirable energy of formula in upper strata return air channel
The blast in outside in the first filter screen 3 of enough effective balances and the second filter screen 5, it is ensured that distinguished and admirable stabilization.
The beneficial effects of the utility model are：By-pass can be opened when outside air temperature is more comfortable than indoor air temperature makes
Clean fresh air is directly entered interior, effectively reduces indoor cooling and heating load, energy-efficient.When outer temperature is more or less the same indoors, change
Hot device heat exchange efficiency is low when being not enough to make up the energy lost by total-heat exchanger, opens by-passing valve, makes clean fresh air straight
Connect and get in, effectively extension total-heat exchanger service life, power of fan in such cases is reduced, while can effectively put down
The blast weighed between the first filter screen and the second filter screen, reduces the maintenance cost of filter screen.
