Wherein, air inlet 3 and air outlet 2 can all or part ofly be positioned at body of wall 1 outside of machine room.
Optionally, filter 4 can be the filter of electrostatic filter or other type.
The fresh air introducing apparatus of band self-cleaning function of the present invention and self cleaning method thereof can be used for air-conditioning equipment, can be used as the gravity-flow ventilation cooling-part of air-conditioning equipment, be installed in the air-conditioning equipment, controller wherein, blower fan etc. can be subjected to the relevant device in air-conditioning system main controller controls or the multiplexing air-conditioning system, can be powered by air-conditioning system; During practical application, do not get rid of this fresh air introducing apparatus yet and can independently use, power supply separately, control voluntarily.
The self cleaning method of the fresh air introducing apparatus of band self-cleaning function of the present invention is: first air-valve 8 and second air-valve 10 are closed, the 3rd air-valve 9 is opened; The air-out of the second blower fan 5B is discharged fresh air introducing apparatus by described filter 4, thus the dust on can cleaning and filtering 4 etc.
One embodiment of the present invention when the air-conditioning system operate as normal, are controlled first air- valve 8 and 10 unlatchings of second air-valve respectively by first controller 11 and second controller 13 as shown in Figure 1; Close by the 3rd controller 12 controls the 3rd air-valve 9, air inlet 3 and air outlet 2 are separated.At this moment, under blower fan 5 effects in air inlet duct 7, outdoor air enters air inlet duct 7 from air inlet 3, is transported to the indoor circulation system through air inlet duct 7 then, with the cooling calculator room equipment; Under blower fan 5 effects of indoor air in exhaust passage 6,6 are discharged to outdoor from air outlet 2 through the exhaust passage.When outdoor air entered air inlet 3, dust in air was removed by filter 4 by 3 places at air inlet.
After air-conditioning system operation a period of time, piled up a large amount of dusts on the filter 4, when reaching default degree, need remove laying dust.As shown in Figure 2, control first air-valve 8 respectively and second air-valve 10 cuts out by first controller 11 and second controller 13, at this moment, first air-valve 8 cuts out air outlet 2, and second air-valve 10 cuts off the path between air inlet 3 and the air inlet duct 7; Open by the 3rd controller 12 controls the 3rd air-valve 9, at this moment, form path between exhaust passage 6 and the air inlet 3, under the blower fan 5B effect of room air in exhaust passage 6,6 are discharged to outdoor from air inlet 3 through the exhaust passage, when air is flowed through air inlet 3, the dust on the filter 4 at air inlet 3 places is purged clean.After cleaning finishes, open first air-valve 8 and second air-valve 10 again, close the 3rd air-valve 9, air-conditioning system enters normal operating condition; Can close blower fan 5A for energy-conservation this moment.
In the present embodiment, described first, second, third controller opens and closes the air-valve of being controlled according to the state of air-conditioning system; Can be that master controller in the air-conditioning system initiatively indicates first, second, third controller to carry out corresponding operating, also can be the state that first, second, third controller is inquired after air-conditioning system, carries out corresponding operating then.
In another embodiment, fresh air introducing apparatus is independent the use, or not controlled by air-conditioning system, and fresh air introducing apparatus also comprises a timer, when each timing arrived, described first, second, third controller just changed the keying state of the air-valve of once being controlled; When just powering on, first air-valve 8 controlled respectively by first controller 11 and second controller 13 and second air-valve 10 is opened, and the 3rd controller 12 controls the 3rd air-valve 9 cuts out, and timer begins regularly; When timing arrived, first air-valve 8 controlled respectively by first controller 11 and second controller 13 and second air-valve 10 cuts out, and the 3rd controller 12 controls the 3rd air-valve 9 is opened; When timing arrived once more, first air-valve 8 controlled respectively by first controller 11 and second controller 13 and second air-valve 10 is opened, and the 3rd controller 12 controls the 3rd air-valve 9 cuts out ... by that analogy, thereby can realize automatically cleaning regularly; Timer can be notified first, second, third controller when each timing arrives, also can be intercepted the state of timer by first, second, third controller always.Timer restarts regularly after each timing arrives.
In another embodiment, fresh air introducing apparatus is independent the use, or not controlled by air-conditioning system, and fresh air introducing apparatus also comprises an air quantity inductor and a comparator; Described air quantity inductor is arranged in the air inlet 3 or in the air inlet duct 7, produces one according to air quantity and be used to indicate the signal of telecommunication of air quantity size to send to described comparator; The more described signal of telecommunication of described comparator and a preset threshold send to first, second, third controller with comparative result; When comparative result be less than the time, illustrate that the filter dust is more, need the beginning automatically cleaning, this moment first controller 11 and second controller 13 is controlled first air-valve 8 respectively and second air-valve 10 cuts out, the 3rd controller 12 controls the 3rd air-valve 9 is opened.When comparative result when being equal to or greater than, finish automatically cleaning; First air-valve 8 controlled respectively by first controller 11 and second controller 13 and second air-valve 10 is opened, and the 3rd controller 12 controls the 3rd air-valve 9 cuts out.
Also above-mentioned air quantity inductor can be replaced with a differential pressure sensor; Described differential pressure sensor is used to measure the pressure reduction on described filter 4 both sides, and is used to indicate the signal of telecommunication of magnitude of pressure differential to send to described comparator according to pressure reduction generation one.
Comparator also can directly compare air quantity and air quantity threshold value, or directly compares pressure reduction and threshold pressure differential; Described threshold value, threshold pressure differential or air quantity threshold value can rule of thumb be worth or experiment value obtains.When if the air quantity inductor is arranged in the air inlet 3, be arranged within the filter 4, promptly to make the air that enters air inlet 3 from the outside pass through this air quantity inductor again through filter 4 earlier.
Latter two embodiment is applied in any combination arbitrarily also; Such as being that the air quantity inductor is only responded to intake, promptly only respond to the air quantity that blows to air inlet duct 6 from air inlet 3; When the beginning automatically cleaning, start timer, timing arrives the back and finishes automatically cleaning.
During the dust of the fresh air introducing apparatus of band self-cleaning function of the present invention on scavenge filter, can finish cleaning process automatically, not need shutdown system, also not need filter is pulled down, simple to operation, the cleaning time is short, and cost is low.
The above embodiment is the preferred embodiment that proves absolutely that the present invention lifts, and protection scope of the present invention is not limited thereto.Being equal to that those skilled in the art are done on basis of the present invention substitutes or conversion, all within protection scope of the present invention.Protection scope of the present invention is as the criterion with claims.
