The 3rd, enter into composite filter net 5 through the air after 4 processing of static dust treatment box, effectively remove airborne ozone, TVOC, harmful volatile organic matters such as formaldehyde, toluene, dimethylbenzene have been degraded to carbon dioxide and water, thereby obtained clean nontoxic high-quality air.
The 4th, touch heat exchanger 6 through the pure air after the above-mentioned processing, and be discharged into outdoor air and carry out energy and humidity exchange from indoor by air exhaust passage.
The 5th, clean air enters into new geomantic omen steam blending bin 7, outputs to water vapour in the new geomantic omen steam blending bin 7 with the steam spray nozzle 10 of damping device and enters and mix, thereby realize the wet process that adds of air.
The 6th, the air that process adds after the wet process enters into indoor.
Wherein to be discharged to outdoor process as follows for room air:
The first, open air-out blower fan 2, indoor air is incorporated into air exhaust passage, by the second primary efficient filter screen 8 in the air exhaust passage it is tentatively filtered, with the floccule of airborne larger material dust particle and strip, filter out such as hair, fiber etc., prevent from stopping up air exhaust passage.
The second, the contact with air of processing through the second primary efficient filter screen 8 is to heat exchanger, and will enter the exchange that indoor air carries out energy and humidity by air-supply passage.
Three, arrive outdoor through the Bas Discharged after energy and the humidity exchange.
The static dust ion chamber 4 of this enforcement comprises high-tension electricity abscission zone and accumulation area, and accumulation area includes the collecting plate of aluminium material, and airborne particle and dust enter into is with electric charge after the high-tension electricity abscission zone is ionized; According to the principle of " positive negative is inhaled ", charged dust and particle are played a part efficient dispelling abnormal flavor gas and dust suction by the absorption of the aluminium sheet of reversed polarity, the particle PM2.5 more than 90% can be adsorbed.Simultaneously harmful microorganism such as bacterium, virus, mould etc. are depressed also and can enlarge deadly because of cell hole at high pressure ionization and high-pressure electrostatic, and the sterilizing rate of static dust ion chamber reaches more than 90%.The high-tension electricity of static dust ion chamber 4 is provided by the electric box in the new blower fan.
The air of 6 pairs of air-supply passages of the heat exchanger of present embodiment and air exhaust passage carries out the exchange of energy and humidity, reclaim from the indoor energy that is discharged to outdoor air by heat exchanger, can reclaim 60% energy, reclaim thermal energy in winter, reclaim cold energy summer; Because the heat exchange paper fibre gap in the heat exchanger 6 is very little, only have water vapour molecule to pass through, and larger pernicious gas or the gas with foreign flavor molecule of diameter can't pass through, so also can realize the exchange of the air humidity in air-supply passage and the air exhaust passage by heat exchanger 6, the humidity that effectively keeps room air, thereby further reduced the energy consumption of indoor temperature and humidity airhandling equipment, the consumption of having saved the energy.
Above-described embodiment is the better embodiment of the utility model; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
