Description
Technical field
The present invention relates to a kind of Local Members of air conditioner, and in particular to a kind of air outlet, particularly one kind are applied to
The Winter-summer dual purpose air outlet of large area Smaller load air-supply.
Background technology
The effect of air outlet is that the air for processing air conditioning system sends into interior, with the hall of certain building from ceiling
Air-supply downwards（Top air-supply）As a example by, the requirement to air outlet has two aspects.
One is air supplying distance, is called air circulation jet range.If range is too short（Such as the high 9m of hall, air outlet range is
5m）, 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
9m, air outlet range is 15m）, then jet（Cold wind or hot blast）It is blown to during human body region that wind speed is excessive, causes blowing feeling,
Cause human body uncomfortable.
Two is air-supply range of scatter, corresponding with air supplying distance.Air-supply range of scatter is excessive, then air-supply can be diffused into and be not required to
Where blowing, energy dissipation is caused.Air-supply range of scatter 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
Little, the little range of scatter of then blowing of air supplying distance is big.That is, being directed to air conditioning system, suitable air supplying distance is selected with air-supply diffusion model
The air port enclosed is particularly important.
In addition, air conditioning system now is usually Winter-summer dual purpose system, winter send warm braw, summer to send cold wind.Winter blows
It is to send warm braw from top to bottom, surrounding air is cold.So, air circulation jet can have that what is moved upwards to become in the presence of buoyancy
Gesture.So jet is more difficult to deliver to ground, single diffusibility preferably, namely needs bigger air supplying distance and less air-supply diffusion model
Enclose.In contrast, in summer, warm braw is equally sent from top to bottom in air-supply, and surrounding air is hot.So, air circulation jet can be floating
There is the trend for moving downward in the presence of power.So jet is easier to deliver to ground, single diffusibility is poor.Namely need less
Air supplying distance and bigger air-supply range of scatter.This requires that air outlet is different in the air-supply range having in season in summer in winter two.
In sum, most important two parameters in air port are air supplying distance and air-supply range of scatter, and require a wind

2）The Chinese patent application of the entitled adjustable style of utility model（Application number：02248976.2）, see Fig. 2.Should
In scheme, air port adjusts air circulation jet length by changing the form of air port area.Air port area is turned down, then air output is little, is sent
Wind range diminishes, and resistance is maximum, can be used for summer condition.Air port area is tuned up, then air output is big, and air-supply range becomes big, resistance
Minimum, can be used for winter condition.
3）A kind of Chinese patent application in entitled multistage pressing type quantity-adjustable air port（Application No.
201410315250.4）, see Fig. 3.In this scenario, by the coefficient of partial resistance of regulation air outlet, when resistance coefficient is big, then
Air output is little, and air-supply range diminishes, and resistance is maximum, can be used for summer condition.Resistance coefficient hour, then air output is big, and air-supply is penetrated

The mentality of designing of the present invention is as follows：
（1）First slit air outlet, outer bar slit air outlet in interior first slit air outlet, outer bar slit air outlet
Design, its air circulation jet is scrak type jet, namely jet flow pattern is flat, and angle of flare is big.So such combination air port is special becoming
Suitable for large area Smaller load air-supply operating mode, meet the air-supply of summer in winter and require.
（1）Range is adjusted：
The present invention devises a sandwich air port, namely by bar slit air outlet and its first embedded slit air outlet
The combination air port of formation, sees Fig. 4.The air port area of bar slit air outlet is more than its first embedded slit air outlet.Same
Under amount air quantity, air supply velocity=air quantity ÷ air ports area.Namely under same sample prescription amount, the more big then air supply velocity of air-supply open area is more
It is little.And air-supply range is then relevant with air supply velocity, air supply velocity is bigger, then range of blowing is longer.Namely under same air output, from
The wind range that first slit air outlet of small area is projected is longer, and the wind range projected from large area bar slit air outlet is more
It is short.
So, the present invention is by saving spanner, chute, flexible baffle to build different air output combining forms（Such as 40%
Air quantity enters large area bar slit air outlet, and 60% air quantity enters first slit air outlet of small area）.
Combined by different air quantity, cause large area bar slit air outlet, sending in first slit air outlet of small area
Wind velocity changes.So as to ultimately result in the range length for arranging combination type air circulation jet.
Namely the air circulation jet of the present invention is made up of two aspects, one is that first slit air outlet of small area is sent
Jet, but the air circulation jet that large area bar slit air outlet is sent.Two strands of jets are merged, and send in space.
If the air quantity ratio sent in first slit air outlet of small area is big（Limiting case 100% is complete from first slit of small area
Project in air outlet）.Then blowing under equal air quantity, wind speed is big, and air circulation jet is long.If sending into large area bar slit air outlet
Interior air quantity ratio is big（Limiting case 100% is complete to be projected from large area bar slit air outlet）.Then blow under equal air quantity wind
Speed is little, and air circulation jet is short.
Also wind speed can be by this method carried out, namely range is adjusted.
（2）Deng resistance, air quantity is waited to adjust：
The present invention devises two essentially equal air-supply passages of resistance, and only by the different air-supply passages of feeding
Air output ratio is shown in Fig. 5 adjusting air-supply range.Maximum resistance component in two passages is respectively that a S type article sealings are curved
Head and first can in filler rod sealing flaring and the 2nd S type article sealing elbows and second can in filler rod sealing flaring.First S types article
Seemingly, resistance coefficient is identical for sealing elbow and the 2nd S type article sealing elbow-shapeds body phase, first can in filler rod sealing flaring and second can
Seemingly, resistance coefficient is identical for interior filler rod sealing gradually expanded form body phase.So the resistance+the first caused by a S type article sealing elbows can
The resistance+the second that resistance caused by interior filler rod sealing flaring=the 2nd S type article sealing elbows cause can in filler rod sealing flaring draw
The resistance for rising.Namely in two passages be that air drag is identical.Whether to raise air quantity adjust spanner drive it is flexible every
Plate is moved upwards, causes upper space to diminish, and intake diminishes, or drives flexible baffle downward to air quantity regulation spanner is lowered
Motion, causes lower space to diminish, and intake diminishes.There is no any change in its resistance, only wind in conditioning process
Amount ratio, as air quantity adjusts spanner upwards, moves downward, and generates change.
Shell in the present invention directly connects with airduct, and air quantity adjusts the change in location of spanner and directly results in flexible baffle pair
Air in wind pipeline carries out cutting shunting.Air quantity adjusts the position of spanner on the lower, then air capacity in the air-supply passage of top is big,
Conversely, air capacity then in the air-supply passage of bottom is big, Fig. 6 is seen.
Further, since the resistance in upper and lower two passages is identical, so anyway being adjusted.Upper and lower two passages institute
The resistance for causing is not changed in.Namely anyway adjust, the resistance in whole air port is not changed in, namely the pressure loss does not become
Change.
Also can realize that resistance is constant by said process, the air-supply range under air quantity permanence condition is adjusted.
（3）Globality and necessity that volume adjusting apparatus, air channel part flow arrangement, combination air port are connected with each other
Volume adjusting apparatus include adjusting spanner, chute, flexible baffle, and air channel part flow arrangement includes a S type article sealings
Elbow, first can in filler rod sealing flaring, the 2nd S type article sealing elbows, second can in filler rod sealing flaring.Combination air port includes
Bar slit air outlet, first slit air outlet.Because the purpose of the present invention is not change air quantity, adjust under conditions of resistance
Air port range.The present invention is, by two independent and resistance identical runners, to the different combination air port air-supply of area, to pass through
Inversely prroportional relationship between area and wind speed, realizes that wind speed changes, so as to ultimately result in the range for combining air port change.Cause
This, the most important condition is the air segmentation for first sending into airduct, is not two independent air parts, and this is accomplished by air quantity and adjusts dress
Put；Secondly, it is to say that two independent air portions after segmentation are distributed into two tubings of resistance identical, is that air port air-supply is done
Prepare, this is accomplished by air channel part flow arrangement.Finally, the air after shunting is sent into into interior, this is accomplished by combining air port.
To realize said process, novelty of the present invention devise a S type article sealing elbows, first can in filler rod sealing
Flaring, the 2nd S type article sealing elbows, second can in being mutually combined between filler rod sealing flaring this four parts, define resistance
Power is essentially equal, and effectively two air ducts of segmentation air.Eventually through two independent air ducts, combination type is sent into
Air port, the air supply velocity change by the bar slit in combination air port and in bar slit air outlet, result in penetrating for combination air-supply
Journey is not changing resistance, the change under the premise of air quantity.
The operation principle of the present invention is as follows：
During present invention work, first air is sent in shell 10 by airduct, the air that will be fed into by flexible baffle 9 is divided into
Upper and lower two parts, upper air flows into upper air delivery duct, upper air delivery duct by the top of shell 10, a S type article sealings elbow 3, the
One can in filler rod sealing flaring 4 and first slit air outlet 5 constitute；Lower air flows into lower air delivery duct, and lower air delivery duct is by outer
The bottom of shell 10, Article 2 slit air outlet 6, the 2nd S type article sealings elbow 7 and second can in filler rod sealing flaring 8 constitute；On
Resistance in air delivery duct, lower air delivery duct is identical, namely a S type article sealings elbow 3 and first can interior filler rod sealing flaring 4
Resistance and equal to the 2nd S type article sealings elbow 7 and second can in filler rod sealing flaring 8 resistance and.In inflow in air delivery duct
Spanner 1 is adjusted with air quantity of the air capacity flowed in lower air delivery duct by being connected with flexible baffle 9 and chute 2 is adjusted.
Air is flowed into behind upper air delivery duct, and Article 2 seam can be sent into after interior filler rod sealing flaring 4 through a S type article sealings elbow 3, first
Shape air outlet 6 is simultaneously sent by Article 2 slit air outlet 6.Air is flowed into behind lower air delivery duct, through the 2nd S type article sealings elbow 7,
Second can in send into first slit air outlet 5 after filler rod sealing flaring 8 and sent by first slit air outlet 5.Due to
The area of one slit air outlet 5 and Article 2 slit air outlet 6 is different, so going out wind velocity difference under same air quantity.Such as
Fruit needs long plasma jet range to blow, then be adjusted up air quantity and adjust spanner 1 so that into lower channel air capacity proportion more
Greatly.And if necessary to the air-supply of shorter plasma jet range, then adjust air quantity downwards and adjust spanner 1 so that into the air capacity of upper channel
Proportion is bigger.
The area of Article 2 slit air outlet 6 and first slit air outlet 5 is than determining the maximum of air port range and most
Small distance.If all air quantity are sent from upper air delivery duct, range is most short, now meets the summer condition of short range requirement.
If all air quantity are sent from lower air delivery duct, 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.

Due to the 2nd S type article sealing elbows（7）With a S type article sealing elbows（3）Structure is identical, and first can interior filler rod
Sealing flaring（4）Can interior filler rod sealing flaring with second（8）Structure is identical.So distinguishing operating mode and summer condition condition in the winter time
Under,,.So, namely the resistance under winter condition, summer condition is identical.
The area ratio of bar slit air outlet and first slit air outlet determines：
The most long and most short range of jet can determine according to formula is calculated as below.
In formula, a is turbulivity, determines that value is 0.1 to 0.2, is according to X-shaped or first slit air outlet wind speed
Article 2 slit or first slit air outlet wind speed, jet end wind speed, typically take 0.5m/s, are Article 2 slit or first
Bar slit air outlet wind speed water conservancy diameter, is range.
Have again, according to the computing formula of air quantity：
, that is, bring calculation of range formula into being
Due to, it is known that being 0.5m/s, a is, it is known that be 0.1 to 0.2., it is known that there is the known calculating side in field of heating ventilation air conditioning
Method, so air-supply range x is actually the function of air port water conservancy diameter, namely.So, can be according to bar slit spout in the winter time
Maximum range under operating mode（Determined by space, known in field of heating ventilation air conditioning）, solve shaping slit spout.Likewise, root
According to maximum range of the Article 2 slit air outlet under summer condition（Determined by space, known in field of heating ventilation air conditioning）, solution
