In air channel 20, distribute for making about the air of indoor fan 10 discharges carries out, be provided with the overshooting shape flange 22,23 shown in Fig. 4 positive sectional view.
Turn among Fig. 2, with the sort of structure shown in Figure 1 air intake baffle plate 2 is installed in the periphery of annular mouth 1.
In the outside, be provided with compressor 105, heat exchanger 106 and be taken into mouthfuls 107 and suck extraneous airs and promote the centrifugal outdoor fan 30 of heat exchanger 106 heat exchange from the outdoor air that is located at casing left and right side and end face.The indoor and outdoors fan all is connected with fan motor 108, drives two fan rotations by fan motor 108 rotations.
When carrying out refrigerating operaton, integral air conditioner 100 constitutes the dew passage, so that the dew that occurs flows to the outside bottom half on indoor heat converter 103.
In the periphery of outdoor fan 30, as shown in figure 11, be provided with splash board 35, the dew that it will be stored in the outside bottom half lifts up the vaporific water droplet of formation, blows on the outdoor heat converter 106, has improved the ability of outdoor heat converter 106.
Below, explanation will be used in the example on the indoor fan 10 as the air intake baffle plate 2 of one embodiment of the invention according to Fig. 1.Annular mouth 1 is arranged on the air channel 20 of taking in centrifugal indoor fan 10 and sucks on the suction housing 21 of oral-lateral.One end of annular mouth 1 is arranged on the suction side housing 21, and the other end is inserted in the suction inlet of guard shield 11 of indoor fan 10.In the periphery of annular mouth 1, be equipped with plate is made the circular-arc air intake baffle plate 2 that forms.Air intake baffle plate 2 does not need to cover the full week of annular mouth 1, can not be the C shape (the tabular gusset of semi arch) in the present embodiment yet, can not have the plate-shaped member (gusset) of bend in the periphery setting of annular mouth 1 yet.Present embodiment is the example that the half-round office above annular mouth 1 is provided with circular-arc air intake baffle plate 2.In addition, air intake baffle plate 2 both can be used as the parts different with annular mouth 1 and had been installed on the suction side housing 21 in air channel 20, also can with annular mouth 1 one-body molded the use.
Air intake baffle plate 2 the MD2 above (outside of outline MD2) that the position is preferably in annular mouth 1 outline is set.At least at the flange 22 that is formed at air channel 20 top convexs be formed in the scope of flange 23 of air channel 20 bottom convexs, the direction of rotation that air intake baffle plate 2 is erect be arranged on indoor fan 10 is from flange 22 to flange in 21 the scope.
In addition, the height SH of air intake baffle plate 2 is preferably in from annular mouth 1 suction side housing 21 surfaces to more than the height MH of annular mouth 1.Need not make its integral body all than the projection height of annular mouth 1, as long as can reach the height of effective reduction noise.
The effect of indoor fan 10 is described at the integral air conditioner of said structure.
Suction oral-lateral at the indoor fan of prior art is not provided with air intake baffle plate 2.Therefore, agnogenic noise has appearred.At present, the mechanism that noise is taken place does not have detailed final conclusion, but can obtain a favourable explanation by the visualized experiment of air stream.Below be described.
As shown in Figure 2, the axle center of indoor fan 10 is not on the center line of integral air conditioner transverse width.This is because the cause of taking in compressor 105, and the axle center from the space of taking in compressor 15 to indoor fan needs certain distance.For the air quantity that the blow-off outlet 104 that is located at about the body front is blown out equates, need to determine the shape and the height of flange 22,23 as shown in Figure 4.Because about air channel 20, the height difference of flange, therefore also different about the sectional area that air circulated that blows out from indoor fan 10, under the situation that the equivalent air flows out from about the housing, the side speed that flow area is little is fast, and static pressure is low.For this reason, difference appears in the air velocity of discharging from indoor fan 10 about housing.In the air channel 20 left and right sides air velocity not simultaneously, the air that flows through annular mouth 1 attracted to speed height, air channel 20 sides that pressure is low, at the central part of indoor fan 10 suction inlets, and sucks the relative mobile air turbulence that makes the fan suction inlet of air-flow.Because air turbulence produces the fluid sound, in the front of equipment, noise is higher.Further be elaborated below with Fig. 1, Fig. 4 and Fig. 5.
As shown in Figure 1, because the rotation of centrifugal indoor fan 10 drives, room air is inhaled in the annular mouth 1 by indoor heat converter 103.At this moment with axial main flow, from the peripheral direction inhaled air of annular mouth 1 bore MD1 along the air channel 20 wall 21 surfaces, and, be inhaled in the indoor fan 10 along on the surface of fan shaft to the annular mouth 1 that becomes projecting shape.
Shown in the front view of the integral air conditioner of Fig. 4, because of the rotation of indoor fan 10, the air of discharging towards centrifugal direction be assigned to air channel 20 about.In air channel 20, be provided with and make the overshooting shape flange 21,23 that effectively distributes to the left and right from indoor fan 10 circumferential air of discharging.Illustrate that with example the sectional area A2 of the sectional area A1 of flange 23 sides in air channel 20 and flange 22 sides is the situation of A1＜A2.The flow velocity that makes flange 23 sides is v1, and the flow velocity of flange 22 sides is v2, and the 20 air quantity Q that discharge are identical from air channel, the left and right sides for indoor fan 10.At this moment, the relation of flow velocity v, air quantity Q and sectional area A is v=Q/A, so v1＞v2.About air channel 20, the velocity flow profile of air not simultaneously, flange 23 sides that flow velocity is high are lower than the static pressure of flange 22 sides.Because air flows towards the low direction of pressure easily, so just be directed into flange 23 sides along annular mouth wall flow air.
With Fig. 5 above-mentioned situation is described.Fig. 5 looks from the indoor heat converter side, surrounds the stereogram of suction inlet with annular mouth 1.Shown flowing of annular mouth 1 surperficial air.Left figure on the paper is the figure that air intake baffle plate 2 is not set, and right figure is the figure that is provided with the air intake baffle plate 2 of present embodiment.Shown in left figure,,, when the air 200 of flange 23 sides is drawn onto in the low air channel of pressure 20, formed and opposite the flowing of indoor fan 10 rotations with respect to the rotation of indoor fan 10 in the occasion that does not have air intake baffle plate 2.Like this, just occur and the opposite air-flow of air-flow that is drawn onto indoor fan 10 central parts, make air turbulence at fan suction inlet place, the reason that Here it is causes the fluid sound to occur, and be considered to cause the noise increase.
Mobile corresponding with the air that shows above, the effect that exposed installation is put air intake baffle plate 2 with the right figure of Fig. 5 below.
When the periphery at annular mouth 1 is installed into windshield plate 2, when the wall from indoor inhaled air along suction side housing 21 is inhaled into annular mouth 1, strike on the air intake baffle plate 2, at one end under the state that air velocity reduces, import the suction inlet of indoor fan 10 through annular mouth 1.As described in present embodiment,, utilize the suction inlet of indoor fan 10 that the flow velocity of the air by air intake baffle plate 2 is reduced by the air intake baffle plate 2 of semicircle shape (from circular-arc up to flange 23 of the flange 22 in the high air channel 20 of flow velocity) is set above annular mouth 1.Because indoor fan 10 is to be rotated counterclockwise, indoor fan 10 at present embodiment is rotated counterclockwise as shown in Figure 4, concern as can be known by the flange 22 in air channel 20 and 23 position, at the upper side of the centrifugal fan 10 that covers with air intake baffle plate 2, suck the more than half of air and all flow in the air channel 20 of flange 23 sides.Therefore,, form the relation of v1 v2, the left and right sides static pressure in housing is equated basically by suppress to have suppressed the air quantity of flange 23 sides with air intake baffle plate 2 from the speed of the circumferential air-flow that sucks along the surface.Shown in the right figure of Fig. 5, flow to the central part of indoor fan 10 along annular mouth wall flow air, wind direction is unified into a direction, and air-flow does not get muddled.
Owing to reduced the fluid sound that air turbulence produces, the noise of indoor reduced.Said above that the reason that reduces owing to noise in fact was not very definite, and therefore came the data of comparison indoor side noise to be shown among Fig. 6 by the situation that in fact has or not air intake baffle plate 2.When using identical air quantity to compare, when air intake baffle plate 2 was arranged, noise had reduced 1dB approximately.Learn thus, by on the annular mouth 1 of integral air conditioner 100 indoor fans 10, being installed into the effect that windshield plate 2 just can obtain to make indoor side noise to reduce.
The structure of above-mentioned air intake baffle plate, if the words of the structure of air channel shown in Figure 4 20 and indoor fan 10, if be arranged to penthouse shape (be arranged on the back side in the air channel that be provided with flange) towards counter clockwise direction to flange 23 from flange 22 at least, has the effect that is suppressed at air turbulence in the indoor fan suction inlet, owing to reduced the sound of air-flow, obtained the effect that indoor side noise reduces.
In addition, in the present embodiment, though be the explanation of carrying out at the integral air conditioner that is provided with two indoor blow-off outlets, but, even in the occasion that the flow velocity that a blow-off outlet, air are set increases, same as described above, circumferentially be drawn onto the air stream of fan from fan along annular nozzle surface in the middle of, flow opposite with the fan direction of rotation arranged, have the situation that noise occurs.In addition, when 3 above blow-off outlets are set, (situation of blow-off outlet is set) with positive basifacial about the front, the higher air channel of flow velocity may occur, become the reason that noise takes place in this case.In these cases, the air intake baffle plate of present embodiment also is effective.
Use Fig. 7 that the modified example of air intake baffle plate 2 is described below.
By the effect of air intake baffle plate 2 reduction room noises, even the shape of annular mouth 3 as shown in Figure 7 also has same effect.The annular mouth 3 of Fig. 7 is by blocking the form of air current flow, makes circular-arc gusset 4 one ejection formations on annular mouth wall.When using the indoor fan 10 of counter clockwise direction rotation shown in Figure 4, gusset 4 preferably counterclockwise is being arranged to the penthouse shape from flange 22 at least in the scope of flange 23.The gusset 4 of present embodiment is the C shape with the same covering fan suction inlet of air intake baffle plate 2.Such gusset 4 can suppress to flow to the speed of the air of fan suction inlet, can regulate the speed of left and right sides air-flows in the air channel 20, and is therefore the same with the effect of air intake baffle plate 2, can suppress the disorder of suction inlet air-flow, obtains to reduce the effect of room noise.
In addition, in the above-described embodiments, be not limited to be with circular-arc gusset as air intake baffle plate 2, lower for making the flow velocity in surperficial flow air 200 shown in Figure 5, even straight tabular gusset is set in this upstream of flowing, also can be than the right figure reduction of Fig. 5 noise.
An embodiment of outdoor fan 30 is described with Fig. 8 below.
When the periphery of annular mouth 5 is installed air intake baffle plate 2 shown in Figure 1, air velocity by air intake baffle plate 2 reduces, the speed difference that has suppressed the air-flow of outdoor fan about 30 discharges, controlled from outdoor fan 30 to outdoor heat converter the static pressure distribution in 106 the space, make central part stream along annular mouth 5 wall flow air towards outdoor fan 30, make wind direction unified, air turbulence does not take place.Eliminated the fluid sound that is produced by air turbulence thus, outdoor noise can not lump together with the fluid sound of fan suction inlet, has reduced outdoor noise thus.
In addition, when on outdoor fan 30, not using air intake baffle plate 2, preferably use the annular mouth that gusset 4 is set as shown in Figure 7 on annular mouth 3.
The using method of air intake baffle plate 2 shown in Figure 1 or annular mouth 3 shown in Figure 7 has following 3 kinds of situations.(1) only is used in the fan of indoor.(2) be used in each fan of indoor and outside.(3) only be used in the fan of outside.
The shape of indoor and outdoor fan is described with Fig. 9-11 below.
In Fig. 9, indoor fan 10 comprises having the guard shield 11 that the revolving force of fan motor 108 is sent to the wheel hub 13 of the projection 12 of pivot, is configured in a plurality of blades 14 on the wheel hub 13, each blade 14 is coupled together in a side opposite with wheel hub 13 along certain intervals.The outer diameter D 2 of blade 14 is D2SL 〉=D2 with the relation of the maximum outside diameter D2SL of guard shield 11, rationalizes for making the air-flow velocity distribution of discharging from diagram guard shield 11 sides to wheel hub 13 sides, and the way is provided with pole-changing point 14a therein.In addition, if pole-changing point 14a is not set, also can adopt the shape that 13 side external diameters diminish gradually from guard shield 11 sides to wheel hub.But the relation of the suction inlet inside diameter D 1S of the blade outer diameter D 2H of wheel hub 13 sides and guard shield 11 is D2H＞D1S, with the relation of wheel hub outer diameter D H be D2H＞DH.
In Figure 10, outdoor fan 30 comprise have with the revolving force from fan motor be sent to the projection 32 of rotating center section wheel hub 33, separate the guard shield 31 that certain intervals is configured in a plurality of blades 34 on the wheel hub 33, each blade 34 is coupled together in a side opposite with wheel hub 33.The outer diameter D 2 of blade 34 is D2SL 〉=D2 with the relation of the maximum outside diameter D2SL of guard shield 31, rationalizes for making the air-flow velocity distribution of discharging from diagram guard shield 31 sides to wheel hub 33 sides, and the way is provided with pole-changing point 34a therein.In addition, if pole-changing point 34a is not set, also can adopt the shape that 33 side external diameters diminish gradually from guard shield 31 sides to wheel hub.But the relation of the suction inlet inside diameter D 1S of the blade outer diameter D 2H of wheel hub 33 sides and guard shield 31 is D2H＞D1S, with the relation of wheel hub outer diameter D H be D2H=DH.
Though outdoor fan 30 has been installed the dew that the outside bottom half is stored and has been lifted up, make it blow to splash board 35 on the outdoor heat converter 10, in the present embodiment, displaying but be the example that splash board 35 is installed in guard shield 31 peripheries.Splash board 35 is arranged to ring-type in the periphery of guard shield 31 outer diameter D 2SL.
The structure of general centrifugal fan is as indoor fan 10.What in the present embodiment, the centrifugal fan of indoor and outdoors used is the fan of different blade shapes.
In the suction side heat exchanger to be set opposite with indoor fan 10, and outdoor fan 30 is to discharge side at air heat exchanger is set.That is to say, suck space and emission quotas and separate that this emission quotas surrounds (not shown, as to be separated inside and outside with equipment on the above-below direction by top board and base plate) by fan guard 110 and outdoor heat converter 106 by fan dividing plate 110.And no matter where centrifugal outdoor fan 30 is arranged in, outdoor heat converter 106 all is positioned at the axial of this fan.Therefore, the air of radially discharging from fan is forced to axial flow.In addition, annular mouth is arranged on the fan guard 110 as demarcation strip.Come disposed chamber's internal fan 30 with this annular mouth 5 as suction inlet.Describe this point below in detail.
Here, the occasion of centrifugal fan as shown in Figure 9 is because the blade outer diameter D 2H of hub side is bigger than wheel hub external diameter, when it is used as outdoor fan 30, make air that outdoor fan 30 blows out when axial flow, owing on the hub side blade face, produce the situation that makes axial movement disorder, therefore, follow the disorderly fluid sound that flows and produce, outdoor noise increases, and follows the workload of blade to increase, and the input of fan motor 108 increases.
Therefore, select for use the sort of outdoor fan 30 shown in Figure 10 as outdoor fan 30.That is to say, this outdoor fan 30, because the blade outer diameter D 2H of hub side equates with wheel hub outer diameter D H, the blade area that axial flow counteracts is dwindled, so can reduce the inducement of axial flow disorder, simultaneously, owing to reduced the workload of hub side blade face, thereby the fluid sound is reduced, and the input of motor reduces.
The structure of outdoor fan is become the structure of outdoor fan 30 from the type of indoor fan 10, and when making b3/b2=0.29, under situation about using with identical air quantity, noise reduces about 3dB, motor input minimizing about 30%.
Because indoor fan 10 is that air is discharged towards centrifugal direction, and be discharged into indoorly in this state, therefore when as outdoor fan 30 area of blade 14 being reduced, the discharge capacity of air has just reduced.With the structure of indoor fan 10 become the structure of outdoor fan 30, the result that fan performance is compared is: the words that seek out same air quantity, use the fan of outdoor fan structure to make its revolution rise 7.3%, noise increases 2.5dB, because the revolution n of centrifugal fan and the relation of noise SL are SL=60log (n1/n2), therefore, the revolution increase increases along with also can making noise.Therefore, indoor fan 10 preferably the pass between guard shield suction inlet inside diameter D 1S and the hub side blade outer diameter D 2H be D1S＜D2H.
As mentioned above, adopt present embodiment, the integral air conditioner that can provide indoor side noise to reduce.And, the integral air conditioner that the outside noise reduces and motor input is reduced can be provided.
