Description
Technical field
It the utility model is related to a kind of Local Members of air conditioner, and in particular to a kind of air outlet, particularly one kind are just
In the square Winter-summer dual purpose air outlet of processing.
Background technology
It is indoor that the effect of air outlet is that the air for treating air-conditioning system is sent into, with the hall of certain building from ceiling
Air-supply downwards（Top air-supply）Exemplified by, the requirement to air outlet has two aspects.
First, air supplying distance, is called air circulation jet range.If range is too short（Such as the high 10m of hall, air outlet range is
7m）, then jet（Cold wind or hot blast）Not up to human body region, does not have air-conditioning effect.If range is long（Such as hall's height
10m, air outlet range are 15m）, then jet（Cold wind or hot blast）Wind speed is excessive when being blown to human body region, causes blowing feeling,
Cause human body uncomfortable.
Second, air-supply range of scatter, corresponding with air supplying distance.Range of scatter of blowing is excessive, then air-supply, which can be diffused into, is not required to
The place to be blown, causes energy dissipation.Range of scatter of blowing is too small, then air-supply can not cover whole air-supply region, not have
Air-conditioning effect.
The two concepts are to run counter to concept to air supplying distance with air-supply range of scatter.Air supplying distance is then blown greatly range of scatter
Small, the small range of scatter of then blowing of air supplying distance is big.That is, being directed to air-conditioning system, suitable air supplying distance and air-supply diffusion model are selected
The air port enclosed is particularly important.
In addition, air-conditioning system now is usually Winter-summer dual purpose system, winter send warm wind, and summer send cold wind.Winter blows
It is to send warm wind from top to bottom, surrounding air is cold.So, air circulation jet can have that moves upwards to become in the presence of buoyancy
Gesture.So jet is more difficult to deliver to ground, single diffusivity is preferable, namely needs bigger air supplying distance and smaller air-supply diffusion model
Enclose.In contrast, cold wind is equally sent from top to bottom in summer, air-supply, surrounding air is hot.So, air circulation jet can be floating
There is the trend moved downward in the presence of power.So jet is easier to deliver to ground, single diffusivity is poor.Namely need smaller
Air supplying distance and bigger air-supply range of scatter.This requires that the air-supply range that air outlet has in season in summer in winter two is different.
In summary, most important two parameters in air port are air supplying distance and air-supply range of scatter, and require a wind

Mentality of designing of the present utility model is as follows：
（1）Interior square air outlet, foreign side's round wind outlet
Why from interior square air outlet, foreign side's round wind outlet, it is because square air port is easy to manufacture to process, more can
Meet economical requirement.
（2）Range is adjusted：
The utility model devises a sandwich air port, namely by square round wind outlet and its embedded square air-out degree of lip-rounding
Into combination air port, see Fig. 5.The air port area of square round wind outlet is more than its embedded square air outlet.Under same amount air quantity,
Air supply velocity=air quantity ÷ air ports area.Namely under same air quantity, the air-supply more big then air supply velocity of open area is smaller.And blow
Range is then relevant with air supply velocity, and air supply velocity is bigger, then range of blowing is longer.Namely under same air output, from small area
The wind range that square air outlet projects is longer, and the wind range projected from large area side's round wind outlet is shorter.
So the utility model by adjusting volume damper to build different air output combining forms（Such as 30% wind
Amount enters large area side's round wind outlet, and 70% air quantity enters the square air outlet of small area）.
Combined by different air quantity, cause large area side's round wind outlet, the air supply velocity in the square air outlet of small area
Change.So as to ultimately result in the range length for arranging combined type air circulation jet.
Namely air circulation jet of the present utility model is made up of two aspects, first, the square air outlet submitting of small area is penetrated
Stream, second, the air circulation jet that large area side's round wind outlet is sent out.Two strands of jets are merged, and are sent into space.Such as
The air quantity ratio that fruit is sent into the square air outlet of small area is big（Limiting case 100% projects out of small area square air outlet entirely）,
Wind speed of then being blown under equal air quantity is big, air circulation jet length；If it is big to be sent into the intraoral air quantity ratio of large area side's annular air
（Limiting case 100% is entirely from the intraoral injection of large area side's annular air）, then wind speed of being blown under equal air quantity is small, air circulation jet
It is short.
Also wind speed, namely range regulation can be carried out by this method.
（3）Deng resistance, air quantity is waited to adjust：
The utility model devises two essentially equal air-supply passages of resistance, including upper air-supply passage and lower air-supply are led to
Road, and air-supply range is adjusted only by the air output ratio in different air-supply passages is sent into, see Fig. 4.In two passages
Maximum resistance component be respectively the first S type square opening elbows and first can the side's of embedding collar extension flaring and the 2nd S type square opening elbows and
Second can the side's of embedding collar extension flaring.Seemingly, resistance coefficient is identical for first S type square opening elbows and the 2nd S type square opening elbow-shapeds body phase, the
One can the side's of embedding collar extension flaring and second can the side's of embedding collar extension gradually expanded form body phase seemingly, resistance coefficient is identical.So the first S type square openings
Resistance+the first caused by elbow can be caused by the side's of embedding collar extension flaring the S type square opening elbows of resistance=the 2nd caused by resistance+
Second can resistance caused by the side's of embedding collar extension flaring.Namely in two passages it is that air drag is identical.Whether upper air duct
Electric control valve turn down, cause upper air duct intake to diminish, or lower air duct electric control valve is turned down, causes lower air duct air intake
Amount diminishes.Its resistance is no in conditioning process to occur any change, only air quantity ratio, with upper lower air duct motorized adjustment
The aperture of valve generates change.
Shell in the utility model directly connects with airduct, and air-supply deflector shunts to the air in air channel.Separately
Outside, because the resistance in upper and lower two air channels is essentially identical, so anyway being adjusted, caused by upper and lower two air channels
Resistance does not change substantially.Namely anyway adjust, the resistance in whole air port does not change, namely the pressure loss does not become
Change.
Also it can realize that resistance is constant by said process, the air-supply range regulation under air quantity permanence condition.
（4）The globality and necessity that volume adjusting apparatus, air channel part flow arrangement, combination air port are connected with each other
Volume adjusting apparatus includes electric control valve, and it is curved that air channel part flow arrangement includes air-supply deflector, the first S type square openings
Head, first can the side's of embedding collar extension flaring, the 2nd S type square openings elbow, second can the side's of embedding collar extension flaring.Combination air port includes Fang Huan
Shape air outlet, square air outlet.Because the purpose of this utility model is not change air quantity, regulating tuyere is penetrated under conditions of resistance
Journey.The utility model is by two independent and resistance identical runners, and the combination air port different to area is blown, and passes through face
Inversely prroportional relationship between product and wind speed, realize that wind speed changes, changed so as to ultimately result in the range in combination air port.Cause
This, the most important condition is that the air for being first sent into airduct is split, and is divided into two independent air parts, this adjusts with regard to air requirement and filled
Put；Secondly, it is that two independent air portions after segmentation are distributed into two pipe-line systems of resistance identical, is done for air port air-supply
Prepare, this just needs air channel part flow arrangement.Finally, the air after shunting is sent into interior, this just needs to combine air port.
To realize said process, the utility model is innovative to be devised the first S type square openings elbow, first can embed Fang Huan
Mouthful flaring, the 2nd S type square openings elbow, second can be mutually combined between the side's of embedding collar extension flaring this four parts, form resistance
Power is essentially equal, and effectively two air ducts of segmentation air.Eventually through two independent air ducts, combined type is sent into
Air port, changed by combining rectangle in air port and the intraoral air supply velocity of square annular air, realize air-supply and do not changing resistance
The change of range under the premise of power and air quantity.
Compared with existing air outlet, the utility model has following two features：During regulation air-supply range, air-supply air quantity is not
Change.Ensure the stability of indoor air environment.
During regulation air-supply range, blast pressure does not change.Ensure the steady energy-saving run of breeze fan.
Operation principle of the present utility model is as follows：
During utility model works, air is sent into shell 10 by airduct first, by baffle upper plate 11, chin spoiler
12 drainage and the barrier effect of middle deflector, the air that will be fed into are divided into two parts up and down, and upper air is flowed into and blown
Road, upper air delivery duct can embed Fang Huan by the space between the middle deflector 13 of baffle upper plate 11, the first S type square openings elbow 3, first
Mouth flaring 4 and square round wind outlet 6 form；Lower air flows into lower air delivery duct, and lower air delivery duct is led by chin spoiler 12 and centre
Space, square air outlet 5 between flowing plate 13, the 2nd S type square openings elbow 7 and second can the side's of embedding collar extension flaring 8 form；On give
Resistance in air channel, lower air delivery duct is identical, namely the first S type square openings elbow 3 and first can the side's of embedding collar extension flaring 4 resistance
Power and equal to the 2nd S type square openings elbow 7 and second can the side's of embedding collar extension flaring 8 resistance and.With flowing into air delivery duct in inflow
Air capacity in lower air delivery duct is adjusted by volume damper I2 and II9.After air flows into upper air delivery duct, by the first S
Type square opening elbow 3, first can enter square round wind outlet 6 after the side's of embedding collar extension flaring 4 and be sent out by square round wind outlet 6.It is empty
After gas flows into lower air delivery duct, square air outlet 5 can be sent into after the side's of embedding collar extension flaring 8 by the 2nd S type square openings elbow 7, second
And sent out by square air outlet 5.Because square air outlet 5 and the area of square round wind outlet 6 are different, so under same air quantity
Go out wind velocity difference.Blown if necessary to long plasma jet range, then make electric control valve II9 aperture more than electric control valve I2's
Aperture, the air capacity proportion into lower air duct are bigger.And blown if necessary to shorter plasma jet range, then make electric control valve
II9 aperture is less than electric control valve I2 aperture so that the air capacity proportion into upper air duct is bigger.
The maximum and minimum range that are decided by air port range of the area ratio of square round wind outlet 6 and square air outlet 5.Such as
All air quantity of fruit are sent out from upper air delivery duct, then range is most short, now meets the summer condition of short range requirement.If all wind
Amount is sent out from lower air delivery duct, then range is most long, now meets the winter condition of long shot range request.
Resistance and equal mechanism characteristicses ensure：
According to known in field of heating ventilation air conditioning, pipeline local resistance can be calculated by following formula.
The local resistance formula of pipe fitting is：
Local Members in upper air duct include the first S type square opening elbows（3）, first can the side's of embedding collar extension flaring（4）
Its local resistance and it is
Local Members in lower air duct include the 2nd S type square opening elbows（7）, second can the side's of embedding collar extension flaring（8）

Due to the 2nd S type square opening elbows（7）With the first S type square opening elbows（3）Structure is identical, and first can the side's of embedding collar extension
Flaring（4）Can the side's of embedding collar extension flaring with second（8）Structure is identical.So under the conditions of distinguishing operating mode in the winter time and summer condition.So, namely the resistance under winter condition, summer condition is complete
It is identical.
The area of square round wind outlet and square air outlet ratio determines：
The most long and most short range of jet can determine according to formula is calculated as below.
When the utility model begins to use, by regulation, the different air circulation jet length of formation are shown in Fig. 7.It can be seen that fixed
Air quantity, under the conditions of determining resistance, the utility model can effectively realize jet length change.
