To adjust the air velocity etc. for flowing through the position of air outlet 10.It should be appreciated that the data of first spray orifice 42 not office
It is limited to the present embodiment, can be rationally set according to the length of actual turbulence plate 4；First flap 43 is also not necessarily required to and institute
The quantity for stating the first spray orifice 42 corresponds, and can rationally set quantity according to the actual requirements.Wherein, the irregular hole 45 has
There is the aperture that multiple diameters differ, specifically can be according to being actually needed reasonable setting.
In another embodiment, reference picture 3, the turbulence plate 4 also include electric with the stepping on the plate body 41
Machine 3 is fixedly connected and can be with described first with the second flap 46 of the position correspondence of the first spray orifice 42, second flap 46
The relatively described plate body 41 of flap 43 is located at the same side, also can relatively described plate body 41 set.The bottom of second flap 46 with
The plate body 41 is rotatablely connected, and second flap 46 is provided with the 3rd spray orifice 47.When the flap of the first flap 43 and second
When 46 relatively described plate bodys 41 are set, when control panel receives fast cooling instruction, then the turbulence plate 4 is controlled with the first spray
Hole 42 flows through the air velocity of the position of air outlet 10 to adjust；When the control panel receives slow cooling instruction, then
Control stepper motor 3 drives first flap 43 to turn to the position being bonded with the plate body 41, preferably covers the air-out
Mouthfuls 10, to flow through the air velocity of the position of air outlet 10 by the second spray orifice 44 on first flap 43 to adjust；
When the control panel receives temperature instruction up to standard, then control stepper motor 3 to drive first flap 43 to reset, drive simultaneously
Move second flap 46 and turn to the position being bonded with the plate body 41, the air outlet 10 is preferably covered, with by described
The 3rd spray orifice 47 on second flap 46 flows through the air velocity of the position of air outlet 10 to adjust.When first flap 43
When being located at described 41 the same side of plate body with second flap 46, specific control process is roughly the same with said process, wherein, when
When the control panel receives temperature instruction up to standard, then control stepper motor 3 and first flap 43 need not be driven to reset
Only second flap 46 need to be driven to turn to the position being bonded with first flap 43, preferably cover the air outlet
10, to flow through the air velocity of the position of air outlet 10 by the 3rd spray orifice 47 on second flap 46 to adjust.
Further, the diameter of the 3rd spray orifice 47 is less than the diameter of the spray orifice 44 of the first spray orifice 42 and second.Institute
Multiple apertures 471 of the 3rd spray orifice 47 with a hole center 470 and from the 470 outside homogeneous radiation of hole center distribution are stated,
The aperture of the aperture 471 is outwards gradually increased by the hole center 470.
Further, the turbulence plate 4 has a predetermined thickness, and the pore size of the spray orifice is along the pre- of the turbulence plate 4
Determining thickness direction has first paragraph, second segment and the 3rd section, and the pore size of the second segment is less than the first paragraph and the
Three sections of pore size.It is understood that the pore size relation of the first paragraph and second segment can be according to being actually needed
Rationally set, specifically can refer to and be introduced below.
In the present embodiment, air velocity is progressively controlled and reduced to control Air Temperature by the combination in the hole of different-diameter
The method of degree, the speed of spray orifice is related with the diameter of spray orifice to the distance of jet-stream wind, by controlling injection diameter and spray orifice
Effluxvelocity come control human comfort area allow air velocity scope.
As shown in figure 4, the air velocity of spray orifice can be adjusted by adjusting W2 and W1 ratio, by adjusting H2 and H1
Ratio and W2 size adjust the range of the jet of turbulence plate 4.
Because the import direction cross section overdraught speed of turbulence plate 4 is heterogeneous, broad in the middle, both sides are small, according to formula:
In formula：VxRepresent axis speed of the jet at away from hole center x, m/s；V0The axis speed at jet exit is represented,
m/s；X represents the distance away from hole center, m；A0Represent the area in hole, m2；K1Jet axis velocity attenuation coefficient；KnProportionality coefficient,
Determined by experiment.
It is uniform to the air-out of turbulence plate 4 because the speed of orifice center and the area of spray orifice are related, then to determine spray orifice
Relevant parameter, and obtain section VELOCITY DISTRIBUTION.Approximate substitution can be theoretically distributed with jet, or is approached by simulation,
Or direct experimentally VELOCITY DISTRIBUTION on testing section.
Specifically can first on turbulence plate 4 uniform spray orifice central point, then using central point as basic point, tested with test method
The speed of each central point, and the relevant parameters such as the area of spray orifice are calculated according to above-mentioned formula.It so can accurately draw turbulent flow
The size relevant parameter of each spray orifice on plate 4.
Or reference picture 5, the diffuser top that air-conditioner air outlet 10 can be crossed to vortex tongue regard a nozzle, rear diffuser as
Go out stream and be considered as jet, as the absolute velocity on each section of increase of range is distributed gradual flattening, the speed on each section of jet
Degree, which is distributed, has similitude, and the VELOCITY DISTRIBUTION on its section can use following formula approximate：
Wherein, y is that any point is to the distance of nozzle center on section, and b is jet half width on the section, and u0 represents jet
Maximal rate, u represent the speed of y points on section.When turbulence plate selectes a certain section, the half-breadth can in this section is determined as
, it is known that due to being known Q by the flow of outflow port, the length of outflow port is L, so the mean flow rate in section can be asked simply
Take：
Then：
Wherein k is a constant.
So, the size relevant parameter of each spray orifice on turbulence plate 4 can also be drawn.
The present invention is controlling the same of indoor temperature by the turbulence plate 4 combined in the setting individual layer different pore size of air outlet 10
When can control air velocity.It is understood that air velocity, air quantity and wind direction can be by spray orifice shape and hole
Footpath controls.
The preferred embodiments of the present invention are these are only, are not intended to limit the scope of the invention, it is every to utilize this hair
The equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
