Description
[technical field]
The present invention relates to a kind of method keeping air quality within doors, particularly keep the air of object space fresh and the method for cleaning with air device for deep cleaning, described object space refers to the space close to closing, such as within doors.
[background technology]
Social air pollution harm health of people now, harmful substance too much in air is also degrading indoor environment, is developed various air cleaner and air purifier, described air purifier, One's name is legion, and only patent application just exceedes several thousand.Air purifier as described in Authorization Notice No. CN2300030Y and the air-purifying humidification device etc. as described in Authorization Notice No. CN2290801Y.Though these purifiers can purify air, also there are some shortcomings.
The air purifier of background technology.The overwhelming majority relates to structure and structure and the material etc. of the purification of air, seldom relates to using method, and thinks deeply for the entirety of the result of use of object space.
At present, the method that the maintenance air for independently object space is fresh and clean, mainly uses various air purifier.And air purifier is placed in space, circularly purifying is carried out to air.Concrete scheme is numerous, described air cleaning unit, and the overwhelming majority is all filter, and the air filtration cleaning principles such as static electric field process carry out the thinking of repeated multiple times circularly purifying to air.We are referred to as circularly purifying method.Described air purifier is also referred to as circulated air air purifier.Such as, the Household Air Purifier of numerous brand.And the purification techniques to develop for above-mentioned Household Air Purifier.Of a great variety in view of Household Air Purifier, substantial amounts, does not just state one by one.
Generally, in a separate space closed of specifying, air is purified five times repeatedly, the clean level of air can be made to double.Because be circularly purifying, need for a long time and very large purification of air amount, the cleaning keeping object space air quality can be reached.
Circularly purifying method shortcoming is: can not adapt to the house of larger area or the purification of air in space, generally circulated air purification, and no matter the size of air purifier and air quantity have much, and the space be merely able to below for 100 square meters purifies.More than 100 square meters, because the local infinite loop phenomenon of air can be produced, and is similar to short circuit.And the whole air of an air purifier to larger object space can not be realized purify.Especially the space more than hundreds of square meter, be namely that multiple stage air purifier works simultaneously, clean-up effect is also bad.Conclusion is current air purifier, can not ensure the quality of the air of the entirety of large space.
Another shortcoming of circularly purifying method is: current air purifier, and purgeable pollutant kind is few.Such as, be generally with aerosol PM2.5 for purification object pollutant, and for being less than the pollutant of PM2.5, the pollutant of such as PM0.2, clean-up effect is then very poor.Because most of air cleaning unit uses the filtering material based on HEPA.In addition, if there is a large amount of thio-alcohol foul smell in air, containing the air of the gaseous type pollutant of the non-pm2.5 type such as organic exhaust gas of dioxin, then can not effectively process.
Another kind, the method that the air quality of conventional maintenance object space is pure and fresh is exactly ventilation.The problem of the method is, the air quality for the fresh air of ventilation cannot ensure, especially in the house of the heavier ambient area of air pollution, for the air changed, quality own is exactly underproof.Therefore common ventilation, almost cannot accomplish the air cleaning keeping object space.
In addition, also have a lot of building to adopt the central air-conditioning concentrated at present, and set up concentrated air refreshing tube device, it is provided with simple filtration and purifier in ventilation pipeline opening.Its shortcoming is, is difficult to carry out purification of air for nearly all pollutant.This main cause is the air blast for the central air-conditioning of taking a breath and ventilate, and cannot provide necessary and enough large blast.Because the air blast of all types and model under lower noise, can provide the blast of more than several kPas hardly in the world at present.There is no the purification result that blast just can not be realized ideal.
Namely can not in low noise and two indexs producing larger blast seeking balance.There is no larger blast, just cannot realize carrying out desirable physical cleaning to air at all.Described desirable physical cleaning, refers to close to desirable purification result, and such as, by the solid particle in air, the particle of sizes as all in PM10, PM2.5, PM1 etc. all drops to 0 this limit.
[summary of the invention]
