Description
Technical field
The utility model relates to a kind of room conditioning system, especially a kind of control indoor air stream to ventilation unit.
Background technology
Existing indoor new wind ventilation and air conditioning system, new wind replenish the back to be mixed with former room air, and its effect is the original air of dilution.Because the exhaust outlet of existing air-conditioning system arbitrarily is provided with, if when in the former air pollutant being arranged, it thoroughly can't be discharged outdoorly, make that indoor to change wind not thorough.With fever clinic of hospital is example, and prescription on individual diagnosis person may have bigger infectiousness, and this infection the most rambunctious be exactly by air borne, the main media of its propagation is the airborne suspended particulate substance that sucks.Though the ventilation sterilizing equipment decontaminating apparatus is arranged in clinic, because the mobile of air be irregular, and the fresh air supply mode is dilution, act on limited, so the generation that can not effectively keep off infection.Simultaneously traditional its comfortableness of aircondition is difficult to satisfactory.
The utility model content
The purpose of this utility model is to solve the problems referred to above that existing aircondition exists, provide a kind of control indoor air stream to ventilation unit, utilize being oppositely arranged of airduct, air outlet, return air inlet, control the main flow direction of room air, thereby realize the displacement of room air.
The utility model provides a kind of control indoor air stream to ventilation unit, form by blower fan, ajutage and backwind tube, described ajutage and backwind tube are installed on the intersection of room end face and facade, the outdoor new wind air inlet that is provided with on the blower fan is connected with ajutage, the exhaust outlet that is provided with on the blower fan is connected with backwind tube, ajutage is provided with an above air outlet, and backwind tube is provided with and the corresponding return air inlet of air outlet.
Because the utility model is provided with air outlet and return air inlet according to application target in the room, zone between air outlet and return air inlet forms the air-flow of directed flow, replenishes new wind with method of replacement, discharges original air simultaneously, therefore, can prevent the contaminated air reverse flow.
The beneficial effects of the utility model are:
1. being provided with rationally of air outlet and return air inlet replenished new wind and discharged indoor foul atmosphere in the mode of displacement, changes wind efficient height.
2. can control the flow direction of air-flow, pollution sources can not reversely be propagated, thereby prevented by airborne pollutant, virus etc.
3. can make the air spontaneous current of scavenging flow in complying with building to, comfortableness is good.
4. application places is extensive, as office, classroom, meeting room, market etc., is specially adapted to hospital's clinic, Waiting Area, entrance hall, ward etc.

Among the figure; 1. new wind air inlet, 2. blower fan, 3. exhaust outlet, 4. backwind tube, 5. return air inlet, 6. air outlet, 7. ajutage.
The specific embodiment
For the utility model there being further understanding, structure described in the utility model is described in detail below in conjunction with embodiment and accompanying drawing.
Fig. 1 be the utility model a kind of control indoor air stream to the structural representation of ventilation unit, ajutage 7 and backwind tube 4 are installed on the intersection of room end face and facade, blower fan 2 is installed on outdoor, new wind air inlet 1 is connected with ajutage 7 by blower fan 2, exhaust outlet 3 is connected with backwind tube 4 by blower fan 2, ajutage 7 is provided with an above air outlet 6, and backwind tube 4 is provided with and air outlet 6 corresponding return air inlets 5.
Among first embodiment of the utility model shown in Figure 2, the air outlet 6 and the return air inlet 5 that are provided with respectively on ajutage 7 and the backwind tube 4 are parallel to the room end face, air intake and air draft are carried out simultaneously, and arrow is represented the main flow direction that air flows, and realize fresh-air ventilation in the mode of replacing.
Among second embodiment of the utility model shown in Figure 3, ajutage 7 and backwind tube 4 are provided with two groups of above air outlets 6 and return air inlet 5, the room is divided into a plurality of ventilations space, arrow is represented the main flow direction that non-interfering air flows, by diagram as can be seen, and the leading airflow direction of this structure independently not disturb separately, form two zones, thereby avoided the cross flow one of foul atmosphere, reduced the possibility of cross pollution, be applicable to doctors and patients places such as hospital.
Among the 3rd embodiment of the utility model shown in Figure 4, the return air inlet 5 that is provided with on the backwind tube 4 is installed in the room end face, can concentrate the central authorities that are installed in the room end face, and ajutage 7 is provided with a plurality of air outlets 6, is installed in the below of metope all around, room respectively.Fresh air from around air outlet 6 slowly add to the room lower space, after room thermal source (people, thing heat radiation) heating, rise gradually, take away the pollution (spittle and other pellet) that the people breathes in a minute, smoking produces, the last uprush that is formed by top return air inlet 5 is fast taken away, and reduces air-polluting horizontal transmission.Be suitable for meeting room, the use of public place.
In the utility model, in the ajutage purification filtering assembly can be installed, as screen pack or disinfector, when outdoor air when new wind air inlet 1 enters ajutage 7 by blower fan 2, purification sterilization through the purification filtering assembly guarantees the air cleaning in the inlet chamber, no dirt.
The utility model by to ajutage, backwind tube and the air outlet of ventilation unit, return air inlet in indoor reasonable setting, the air flow in room can be controlled to be one-way flow, two-way flow.The air spontaneous current of considering whole building simultaneously to, make this controlled air main flow direction carry out room ventilation in the mode of new wind displacement, the novel wind energy that replenishes is " displacement " original air thoroughly, and can control the flow velocity of new wind, to guarantee indoor air comfort.
