Abstract
The present invention relates to a centralized cleaning air conditioner system for effectively purifying indoor air. The system comprises a primary efficiency filter (1), a blower fan (2), an air conditioner unit (3), a middle efficiency filter (4) and an air conditioner room (7). The present invention is characterized in that an adsorption type purifier (5) and a humidifying device (6) are added into the air conditioner system. For the centralized air conditioner system, a part of indoor regenerated air is exhausted outdoors, and the other part of the indoor regenerated air is mixed with fresh air. Then, the indoor regenerated air and the fresh air are introduced into the primary efficiency filter (1) to be purified. Process mixed air enters the combined air conditioner unit (3) through the blower fan (2) to be processed to a proper temperature, and enters the middle efficiency filter (4). Finally, the air processed by the middle efficiency filter (4) passes through the adsorption type purifier (5) and the humidifying device (6) to be conveyed into the air conditioner room (7). The indoor air purifying technology and the air conditioner system of the present invention are utilized to effectively reduce the concentration of indoor air pollutants in the centralized air conditioner system, effectively avoid relevant diseases generated by various pollutants, and provide a comfort and healthy indoor environment for people.
Description
Technical field
The invention belongs to the environmental protection field, particularly a kind ofly can effectively remove indoor air pollutants, improve the centralized clean air-conditioning system of IAQ.
Background technology
The seriousness of room air pollution is more and more recognized by people.Indoor pollutant mainly is divided into suspended particulate substance and gaseous contaminant two big classes.Suspended particulate substance comprises inorganic and organic particulate matter, microorganism and biological colloidal sol, as asbestos, glass fibre, fungi, bacterium, protozoan, virus, pollen etc.; Gaseous contaminant is divided into organic compound, organic compound, radioactive substance such as CO, CO
2, NO
2, SO
2, VVOC, VOC
s, SVOC
s, radon etc.Along with continuing to bring out and the generally use of air-conditioning system of various very different construction materials, ornament materials, the more and more higher and long-term co-existence of the concentration of indoor pollutant is in indoor, caused various and room air pollution diseases associated.Allow indoor various air pollutant concentrations reduce, the indoor air quality that secures good health has two kinds of methods usually.A kind of is to dilute or replace room air, reduction pollutant levels with a large amount of fresh outdoor airs.But owing to being on the rise of city environmental pollution, particularly near the street of prosperity, because a large amount of dischargings of vehicle exhaust, outdoor air itself pollutes very serious, if these and stale " new wind " do not add any processing and directly send into indoorly, aggravated the deterioration of indoor air quality on the contrary.In addition, handle a large amount of new wind and need expend a large amount of cold (heat) and air conveying capacity.Another kind is the thick effect of dress, middle effect or a high efficiency particulate air filter on the assembled air-conditioner unit, and new wind and return air are carried out filtration treatment.But the filter that generally adopts only has filtration to a certain size suspended particulate contaminants at present, and can only adsorb gaseous contaminant a certain amount of, particular types, and the airborne most gaseous contaminants of indoor or outdoors are not had scavenging action.Traditional clean air-conditioning system just effectively is reduced to certain standard with particulate pollutants such as dust, does not really remove indoor gaseous contaminant, and these gaseous contaminants healthy arch-criminal that is harm humans.Therefore, developing a kind of centralized clean air-conditioning system that can effectively remove indoor air pollutants, especially gaseous contaminant has very important significance.
Summary of the invention
The objective of the invention is to effectively remove indoor air pollutants, especially gaseous contaminant solves the room air pollution problem in the central air-conditioning system, improves IAQ.
A kind of centralized clean air-conditioning system, this system comprises roughing efficiency air filter 1, air blast 2, air-conditioning unit 3, medium effeciency filter 4, air-conditioned room 7, it is characterized in that having added in the air-conditioning system adsorption cleaning device 5, damping device 6.For central air conditioning system, an indoor return air part is discharged to outdoor, another part mixes with new wind, introducing roughing efficiency air filter 1 then together purifies, treated mixing air enters assembled air-conditioner unit 3 through air blast 2 and handles suitable temperature, enters medium effeciency filter 4 then.After the air after medium effeciency filter 4 processing is at last through adsorption cleaning device 5 and damping device 6, send into air-conditioned room 7.
Increase adsorption cleaning device 5 in air-conditioning system, purpose is to remove airborne gaseous contaminant, comprises CO, CO
2, formaldehyde, NH
3, NO
x, SO
xAnd the volatile organic matter of some low concentrations (VOCs) etc.Air after adsorption cleaning device 5 is handled adds air-conditioned room 7 after through damping device 6 air being adjusted to suitable humidity again.So just obtained the suitable air of cleaning and temperature and humidity.Indoor air purification technology and air-conditioning system that utilization the present invention relates to, can effectively reduce the concentration of indoor air pollutants in the central air-conditioning system, effectively avoid because the relevant disease that causes of all contaminations, the indoor environment of a comfortable health is provided for people.

The specific embodiment
In air-conditioning system shown in Figure 1, adsorption cleaning device 5 is installed on the cross section of vertical ventilation pipeline, concrete form such as Fig. 2.Under the air-supply situation, heat insulation seal device 8 and 14 is in open mode, and valve 9 and 13 is in closed condition, and heater 12 and air blast 10 are not worked.When passing through adsorption tower 11 through the air after medium effeciency filter 4 processing, airborne pernicious gas is by the adsorbents adsorb in the tower, and clean air infeeds air-conditioned room after handling by damping device 6 again.When air-conditioning system stops air feed, begin adsorption tower 11 is carried out desorb.At this moment, close heat insulation seal device 8 and 14, heater 12 and air blast 10, valve 9 and 13 is opened, and air enters adsorption tower by air blast from valve 9 adsorption tower is purged, and adsorption tower is heated by heater simultaneously, by adsorbent pernicious gas desorption in the tower, from valve 13 emptyings, the various viruses in the adsorption tower, bacterium etc. at high temperature are killed simultaneously, and adsorbent obtains regeneration.
Adsorbent in the adsorption tower 11 that the present invention relates to can be active carbon particle, activated carbon fiber and other adsorbents, as molecular sieve, silica gel etc.What the heat insulation seal device 8 that the present invention relates to and 14 adopted is disc valve, plays the sealing insulation effect, can also be other heat insulation seal devices.Heater 12 in the clarifier adopts electrical heating or heating using microwave, can also be other heat forms.During adsorption tower 11 desorbs, air blast 10 and valve 9 are arranged on the bottom or the top of adsorption tower, and corresponding drain tap 13 is arranged on the top or the bottom of adsorption tower.
