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 summer in winter temperature difference large area.
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 diffusivity 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 diffusivity 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
Mouth has two kinds of different air supplying distances and air-supply range of scatter, and winter requires that air supplying distance length is little with range of scatter of blowing, the summer
Ji Yaoqiu air supplying distances are short big with air-supply range of scatter.

Power is minimum, can be used for winter condition, and air-valve is turned down, and air output is minimum, and air-supply range diminishes, and resistance is maximum, can be used for summer work
Condition.
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 push 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
Cheng Bian great, resistance is minimum, can be used for winter condition.

Above-mentioned design causes air-supply to be respectively fed to a S type rhombus mouths elbow 3 and second according to a certain percentage and can embed X-type
In mouthful flaring 8, and then send from X-shaped air outlet 5 and rhombus air outlet 6 respectively.
The mentality of designing of the present invention is as follows：
（1）Interior rhombus air outlet, outer X-shaped air outlet
Interior rhombus air outlet, outer X-shaped air outlet why are selected, X-type air outlet is that range is most short, rhombus air outlet is penetrated
Journey is relatively long.So this combination air port is applied to, summer in the winter temperature difference is larger, and required range changes greatly operating mode.
（1）Range is adjusted：
The present invention devises a sandwich air port, namely the group formed by X-shaped air outlet and its embedded rhombus air outlet
Air port is closed, Fig. 4 is seen.The air port area of X-shaped air outlet is more than its embedded rhombus air outlet.Under same 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 less.And blow range then with give
Wind velocity is relevant, and air supply velocity is bigger, then range of blowing is shorter.Namely under same air output, from the rhombus air outlet of small area
The wind range of injection is longer, and shorter from the wind range of large area X-shaped air outlet injection.
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 X-shaped air outlet, and 60% air quantity enters small area rhombus air outlet）.
Combined by different air quantity, cause large area X-shaped air outlet, the air supply velocity in small area rhombus air outlet becomes
Change.So as to ultimately result in the range length of integral combined air circulation jet.
Namely the air circulation jet of the present invention is made up of two aspects, one is the jet that small area rhombus air outlet is sent,
Two is the air circulation jet that large area X-shaped air outlet is sent.Two strands of jets are merged, and send in space.If sent into
Air quantity ratio in small area rhombus air outlet is big（Limiting case 100% is complete to be projected from small area rhombus air outlet）.Then same
Deng blowing under air quantity, wind speed is big, and air circulation jet is long.If the air quantity ratio sent in large area X-shaped air outlet is big（Limiting case
The 100% full injection from large area X-shaped air outlet）.Then blowing 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 rhombus mouths are curved
Head can embed X-type mouth flaring and the 2nd S types rhombus mouth elbow and second and can embed X-type mouth flaring with first.First S type rhombuses
Seemingly, resistance coefficient is identical for mouth elbow and the 2nd S type rhombus mouth elbow-shapeds body phase, and first can embed X-type mouth flaring and second can be interior
Seemingly, resistance coefficient is identical for embedding X-type mouth gradually expanded form body phase.So the resistance+the first caused by a S type rhombus mouth elbows can be embedded
The resistance+the second that resistance caused by X-type mouth flaring=the 2nd S type rhombus mouth elbows cause can embed the resistance that X-type mouth flaring causes
Power.Namely in two passages be that air drag is identical.Whether adjust spanner to rise air quantity and drive flexible baffle upwards
Motion, causes upper space to diminish, and intake diminishes, or drives flexible baffle to move downward to air quantity regulation spanner is lowered,
Lower space is caused to diminish, intake diminishes.There is no any change in its resistance, only air quantity ratio in conditioning process
Example, 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.The position that air quantity adjusts spanner is top, 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 that air quantity adjusts spanner, chute, flexible baffle, and air channel part flow arrangement includes a S type water chestnuts
Shape mouth elbow, first can embed X-type mouth flaring, and the 2nd S type rhombus mouth elbows, second can embed X-type mouth flaring.Combination air port bag
Include X-shaped air outlet, rhombus air outlet.Because the purpose of the present invention is not change air quantity, regulating tuyere is penetrated under conditions of resistance
Journey.The present invention be by two independent and resistance identical runners, to area it is different combination air port air-supply, by area with
Inversely prroportional relationship between wind speed, realizes that wind speed changes, so as to ultimately result in the range for combining air port change.Therefore, primarily
Condition is the air segmentation for first sending into airduct, is not two independent air parts, and this is accomplished by volume adjusting apparatus；Its
It is secondary, it is to say that two independent air portions after segmentation are distributed into two pipe-line systems of resistance identical, it is that air port air-supply is prepared,
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 devises a S type rhombus mouth elbows, first can embed X-type mouth
Flaring, the 2nd S type rhombus mouth elbows, second can embed being mutually combined between X-type mouth flaring this four parts, define resistance
It is essentially equal, and effectively two air ducts of segmentation air.Eventually through two independent air ducts, combined type wind is sent into
Mouthful, the air supply velocity change by the rhombus in combination air port and in X-shaped air outlet, the range that result in combination air-supply is not changing
Become 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 rhombus mouths elbow 3, the
One can embed X-type mouth flaring 4 and rhombus air outlet 5 is constituted；Lower air flows into lower air delivery duct, and lower air delivery duct is by under shell 10
Portion, X-shaped air outlet 6, the 2nd S type rhombus mouths elbow 7 and second can embed X-type mouth flaring 8 and constitute；Upper air delivery duct, lower air delivery duct
Interior resistance is identical, namely a S type rhombus mouths elbow 3 and first can embed the resistance of X-type mouth flaring 4 and equal to second
S type rhombus mouths elbow 7 and second can embed the resistance of X-type mouth flaring 8 and.In inflow in air delivery duct and in the lower air delivery duct of inflow
Air capacity adjusts spanner 1 by the air quantity being connected with flexible baffle 9 and chute 2 is adjusted.Air is flowed into behind upper air delivery duct,
X-shaped air outlet 6 is sent into after a S type rhombus mouths elbow 3, first can embed X-type mouth flaring 4 and is sent by X-shaped air outlet 6
Go out.Air is flowed into behind lower air delivery duct, is sent into rhombus after the 2nd S type rhombus mouths elbow 7, second can embed X-type mouth flaring 8 and is gone out
Simultaneously sent by rhombus air outlet 5 in air port 5.Due to the area difference of rhombus air outlet 5 and X-shaped air outlet 6, so under same air quantity
To go out wind velocity different.If necessary to the air-supply of long plasma jet range, then it is adjusted up air quantity and adjusts spanner 1 so that enter lower channel
Air capacity proportion it is bigger.And if necessary to the air-supply of shorter plasma jet range, then adjust air quantity downwards and adjust spanner 1 so that
Air capacity proportion into upper channel is bigger.
The area of X-shaped air outlet 6 and rhombus air outlet 5 is than determining the maximum and minimum range of air port range.If institute
There is air quantity to send from upper air delivery duct, then range is most short, now meet the summer condition of short range requirement.If all air quantity are equal
Send from lower air delivery duct, then range is most long, now meet 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 a S type rhombus mouth elbows（3）, first can embed X-type mouth flaring（4）
Its local resistance and it is
Local Members in lower air duct include the 2nd S type rhombus mouth elbows（7）, second can embed X-type mouth flaring（8）
Its local resistance and it is
Due to the 2nd S type rhombus mouth elbows（7）With a S type rhombus mouth elbows（3）Structure is identical, and first can embed X-type
Mouth flaring（4）X-type mouth flaring can be embedded 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 X-shaped air outlet and rhombus 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 X-shaped or water chestnut according to X-shaped or rhombus air outlet wind speed
Shape air outlet wind speed, jet end wind speed, typically takes 0.5m/s, is X-shaped or rhombus 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 rhombus spout work in the winter time
Maximum range under condition（Determined by space, known in field of heating ventilation air conditioning）, solve rhombus spout.Likewise, according to X-shaped
Maximum range of the spout under summer condition（Determined by space, known in field of heating ventilation air conditioning）, solve X-shaped spout.From
And draw the area ratio between X-shaped and rhombus air outlet.
