The specific embodiment

Below, the specific embodiment of air conditioner of the present invention (indoor set of air conditioner specifically) is described.In each following embodiment, be example explanation the present invention with the wall indoor unit.In the figure shown in each embodiment, the shape of each unit (or component parts of each unit), size etc., also some situation inequality.

Embodiment 1

< essential structure >

Fig. 1 is the profilograph of indoor set (being called indoor set 100) of the air conditioner of expression embodiment of the present invention 1.Fig. 2 is the stereoscopic figure of this indoor set of expression.This embodiment 1 and after in the embodiment stated, describe the front face side of the left side of Fig. 1 as indoor set 100.The structure of indoor set 100 is described based on Fig. 1 and Fig. 2 below.

(unitary construction)

This indoor set 100, the freeze cycle through utilization circulates cold-producing medium supplies to the indoor air-conditioning subject area that waits to Air Conditioning.Indoor set 100 mainly has housing 1, fan 20 and heat exchanger 50.Housing 1 is formed with and is used for suction inlet 2 that absorbs room air and the blow-off outlet 3 that is used for supplying to Air Conditioning the air-conditioning subject area.Fan 20 is accommodated in this housing 1, sucks room air from suction inlet 2, blows out Air Conditioning from blow-off outlet 3.Heat exchanger 50 is provided in from fan 20 to blow-off outlet on 3 the wind path, produces Air Conditioning through between cold-producing medium and room air, carrying out heat exchange.By these inscapes, in housing 1, be communicated with wind path (arrow Z).Suction inlet 2 forms at the upper opening of housing 1.(specifically, be at housing 1 front face downside) opening forms blow-off outlet 3 in the bottom of housing 1.Fan 20 is provided in the downstream of suction inlet 2 and the upstream side of heat exchanger 50, for example is made up of axial-flow type or mixed flow fan etc.

In addition, indoor set 100 also has control device 281, the rotating speed of this control device 281 control fans 20 and after state blade 70 and left and right sides blade 80 up and down (during the auxiliary blade 71 up and down stated after being provided with, also comprising auxiliary blade 71 up and down) towards (angle) etc.This embodiment 1 and after state in the drawing shown in each embodiment, also omit the diagram of control device 281 sometimes.

In the indoor set 100 that constitutes like this; Because fan 20 is located at the upstream side of heat exchanger 50; So, compare with the indoor set that is located at fan 20 air conditioner before at blow-off outlet 3 places, can suppress to produce the inequality of eddy flow, wind speed profile from the air that blow-off outlet 3 blows out.Therefore, can carry out comfortable air-supply to the air-conditioning subject area.In addition, owing to there is not complicated structure such as fan at blow-off outlet 3 places, so, in the dewfall of the intersection generation of hot gas and cold air, also can easily tackle during for cooling operation.In addition, be cold air, hot gas because fan motor 30 is not exposed to Air Conditioning, so, can be provided long running life.

(fan)

Usually, there is restriction aspect the space in the indoor set of air conditioner being provided with, so fan mostly can not be very big.Therefore, in order to obtain required air quantity, the also fan of a plurality of modest size of row arrangement.The indoor set 100 of this embodiment 1, as shown in Figure 2, along the length direction (in other words, the length direction of blow-off outlet 3) of housing 1, and row arrangement 3 fans 20.According to the indoor set size of now common air conditioner, in order to obtain required heat-exchange capacity, fan 20 is preferably roughly 3～4.In the indoor set of this embodiment 1, fan 20 all is identical shape, and all with identical working speed running, thereby all fans 20 can obtain roughly the same air output.

By such structure, the flowing resistance inner according to institute's required airflow, indoor set 100 makes up number, shape and the size etc. of fan 20, can obtain the best fan design corresponding with the indoor set of plurality of specifications 100.

(horn mouth)

The indoor set 100 of this embodiment 1 is disposing the horn mouth 5 on the pipeline around fan 20.Horn mouth 5 is used for guiding swimmingly the air-breathing and exhaust of fan.As shown in Figure 1, the horn mouth 5 of this embodiment 1 sees it is circular from the plane.In the vertical section, the horn mouth 5 of this embodiment 1 has following shape.Top 5a forms its end and expands the roughly circular arc of opening towards the top.Central portion 5b is that bell-mouthed diameter is certain upstanding portion.Bottom 5c is that the roughly circular arc of opening is expanded in its end towards the below.End (circular arc portion of suction side) by the top 5a of horn mouth 5 has formed suction inlet 2.

In order to reduce component number and to improve intensity, horn mouth 5 for example also can form as one with housing 1.In addition, for example also can it can be loaded and unloaded modularizations such as horn mouth 5, fan 20 and fan motor 30 with respect to housing 1, like this, can improve maintainability.

In this embodiment 1, the end of the top 5a of horn mouth 5 (circular arc portion of suction side), with respect to the opening surface of horn mouth 5 circumferentially, be identical shape.That is, be the direction of rotation at center at rotating shaft 20a with fan 20, horn mouth 5 does not have the structure of breach, rib etc., is the uniform shape with axial symmetry.

Through such formation horn mouth 5, because the end (circular arc portion of suction side) of the top 5a of horn mouth 5 is uniform shape with respect to the rotation of fan 20, so, as the inlet flow of fan 20, also realize uniform airflow.Therefore, can reduce the noise that the bias current because of the inlet flow of fan 20 produces.

(demarcation strip)

As shown in Figure 2, the indoor set 100 of this embodiment 1 is provided with demarcation strip 90 between adjacent fan 20.These demarcation strips 90 are arranged between heat exchanger 50 and the fan 20.That is, the wind path between heat exchanger 50 and the fan 20 is divided into a plurality of wind paths (in this embodiment 1 being 3).Because demarcation strip 90 is arranged between heat exchanger 50 and the fan 20, so the end of a side of joining with heat exchanger 50 is the shape along heat exchanger 50.Specifically, as shown in Figure 1, (that is, see the vertical section of indoor set 100 from the front face side of indoor set 100 to the vertical section of rear side from the right side.Be called the vertical section, right side below) in, heat exchanger 50 is configured to roughly A shape.Therefore, the end of leaning on heat exchanger 50 1 sides of demarcation strip 90 also is an A shape roughly.

The position of the end of leaning on fan 20 sides of demarcation strip 90 for example can determine as follows.Far away and do not produce under the interactional situation in the suction side at a distance of enough when adjacent fan 20, the exit face that the end by fan 20 sides of demarcation strip 90 extends to fan 20 gets final product.But; At adjacent fan 20 at a distance of closer and produce in the suction side when influencing each other; And; When the shape in the end of the top of horn mouth 5 5a (circular arc portion of suction side) can form enough greatly, the end of leaning on fan 20 sides of demarcation strip 90 also can with the mode that do not influence adjacent wind path (with adjacent fan 20 in the suction side not interactional mode) extend to the upstream side (suction side) of fan 20 always.

Demarcation strip 90 can use various materials to form.For example, can use the metal of steel, aluminium etc. to form demarcation strip 90.In addition, for example also can be with formation demarcation strips 90 such as resins.But, because heat exchanger 50 is high temperature when heat supply turn round, so, when demarcation strip 90 is the material formation with low melting points such as resins, can between demarcation strip 90 and heat exchanger 50, form very little space.When demarcation strip 90 is the high material of melting points such as aluminium, steel, also can be demarcation strip 90 and heat exchanger 50 ground connection configuration mutually.At heat exchanger 50 is for example during fin tube type heat exchanger, also can insert demarcation strip 90 between the fin of heat exchangers 50.

As stated, the wind path between heat exchanger 50 and the fan 20 is divided into a plurality of wind paths (in this embodiment 1 being 3).In this wind path, promptly on demarcation strip 90, housing 1 etc., sound-absorbing material is set, can reduce the noise that produces in the pipeline.

In addition, these divided wind paths are seen from the plane, and forming the length of side is the roughly quadrangle of L1 and L2.That is, the width of divided wind path is L1 and L2.Therefore, for example, be arranged on air quantity that the inner fan 20 of the roughly quadrangle that formed by L1, L2 produced effectively through be positioned at fan 20 downstream, by the heat exchanger 50 of L1, L2 area surrounded.

Like this, through being divided into a plurality of wind paths to the wind path in the housing 1, even there is the cycle composition in the flow field that fan 20 forms in downstream, the air that blows out from each fan 20 can not freely move at the length direction (with the direction of Fig. 1 paper quadrature) of indoor set 100.Therefore, the air that blows out of fan 20 can through these fan 20 downstream, by the heat exchanger 50 of L1, L2 area surrounded.As a result, can suppress to flow into the inequality that the air quantity of indoor set 100 length directions (with the direction of Fig. 1 paper quadrature) of whole heat exchanger 50 distributes, thereby have high heat exchange performance.In addition, through with demarcation strip 90 with separating in the housing 1, in 20 in adjacent each other fan, can prevent the interference of the eddy flow that adjacent fans 20 produces.Therefore, the fluid energy loss that the phase mutual interference because of eddy flow produces can be suppressed, the pressure loss of indoor set 100 can be when improving wind speed profile, reduced.In addition, each demarcation strip 90 not necessarily will use a plate to form, and also can use the polylith plate to form.For example, also side heat exchanger 51 sides and rear side heat exchanger 55 sides in front are divided into two demarcation strip 90.Certainly, the position that is bonded with each other of each plate of formation demarcation strip 90 is preferably very close to each other.Through being divided into demarcation strip 90 a plurality of assembleabilities that improve demarcation strip 90.

(fan motor)

Fan 20 is by fan motor 30 driven in rotation.The fan motor 30 that is adopted can be an inner-rotor-type, also can be external-rotor-type.Under the situation of the fan motor 30 of external-rotor-type, also adopt the hub 21 all-in-one-pieces structures (having rotor on the hub 21) of rotor and fan 20.In addition, the size through making fan motor 30 can prevent the air-flow that fan 20 generates is caused damage less than the size of the hub 21 of fan 20.In addition, the inside of motor configurations, can reduce the direction of principal axis size at hub 21.Through making the structure of easy loading and unloading to fan motor 30 and fan 20, cleaning property also improves.

Through adopt cost than higher DC brushless motor as fan motor 30, can raise the efficiency, improve controlled and realize long lifetime.But, even adopt the motor of other form, also can satisfy elementary function as air conditioner, this is self-evident.

In addition, the circuit of the driving usefulness of fan motor 30 can become one with fan motor 30, also can externally constitute and implement dustproof, fireproof countermeasure.

Fan motor 30 is installed on the housing 1 by motor support 16.In addition; If become the boxlike that is used for CPU and cools off (fan 20, framework, fan motor 30 etc. are integral and by modularization) to fan motor 30; Become the structure that can load and unload with respect to motor support 16, then can improve maintainability, the precision of the bottom clearance of fan 20 also can improve.

In addition, the drive circuit of fan motor 30 can constitute in the inside of fan motor 30, also can be externally.

(motor support)

Motor support 16 has fixed part 17 and support unit 18.Fixed part 17 is equipped with fan motor 30.Support unit 18 is to be used for being fixed to the parts on the housing 1 to fixed part 17.Support unit 18 for example is shaft-like, for example is to extend radially from the peripheral part of fixed part 17 to be provided with.As shown in Figure 1, the support unit 18 of this embodiment 1 extends setting in general horizontal direction.

(heat exchanger)

The heat exchanger 50 of the indoor set 100 of this embodiment 1 is configured in the downwind side of fan 20.This heat exchanger 50 for example can adopt fin tube type heat exchanger etc.As shown in Figure 1, in the vertical section, right side, heat exchanger 50 is cut apart by line of symmetry 50a.Line of symmetry 50a is divided into left and right directions to the scope that is provided with of the heat exchanger in this section 50 in substantial middle portion.That is, front face side heat exchanger 51 is configured in front face side (paper left side among Fig. 1) with respect to line of symmetry 50a, and rear side heat exchanger 55 is configured in rear side (paper right side among Fig. 1) with respect to line of symmetry 50a.Front face side heat exchanger 51 is configured in the housing 1 with rear side heat exchanger 55 in this wise: open with respect to the flow direction expansion of air at the interval that front face side heat exchanger 51 and rear side heat exchanger are 55; Promptly; In the vertical section, right side, the section shape of heat exchanger 55 is roughly A shape.That is to say that front face side heat exchanger 51 disposes with the mode with inclination with the flow direction of rear side heat exchanger 55 with respect to the air of supplying with from fan 20.

In addition, heat exchanger 50 is characterised in that the wind path area of rear side heat exchanger 55 is greater than the wind path area of front face side heat exchanger 51.That is, for heat exchanger 50, the air quantity of rear side heat exchanger 55 is greater than the air quantity of front face side heat exchanger 51.In this embodiment 1, in the vertical section, right side, the length direction length of rear side heat exchanger 55 is longer than the length direction length of front face side heat exchanger 51.Like this, the wind path area of rear side heat exchanger 55 is greater than the wind path area of front face side heat exchanger 51.In addition, other structure (among Fig. 1 the length of depth direction etc.) of front face side heat exchanger 51 and rear side heat exchanger 55 is identical.That is, the heat transfer area of rear side heat exchanger 55 is greater than the heat transfer area of front face side heat exchanger 51.In addition, the rotating shaft 20a of fan 20 is arranged on the top of line of symmetry 50a.

Through such formation heat exchanger 50, compare with the indoor set of the air conditioner before that is located at fan blow-off outlet, can suppress to produce the inequality of eddy flow, inhibition wind speed profile from the air that blow-off outlet 3 blows out.In addition, through such formation heat exchanger 50, the air quantity of rear side heat exchanger 55 is greater than the air quantity of front face side heat exchanger 51.Poor by this air quantity, the air that has passed through front face side heat exchanger 51 and rear side heat exchanger 55 respectively is when the interflow, and the air behind this interflow is towards front face side (blow-off outlet 3 sides) bending.Therefore, needn't make air-flow crooked sharp near blow-off outlet 3, can reduce near the pressure loss the blow-off outlet 3.

In addition, in the indoor set 100 of this embodiment 1, the flow direction of the air that flows out from rear side heat exchanger 55 be from rear side towards the front side flow.Therefore, the indoor set 100 of this embodiment 1 is compared when in the vertical section, right side, being configured to roughly v shape to heat exchanger 50, passed through behind the heat exchanger 50 air flow crooked more easily.

Indoor set 100, owing to have a plurality of fans 20, so weight increases easily.When indoor set 100 increased the weight of, the wall that is used to install indoor set 100 just required to have certain intensity, becomes the restriction of installing.Therefore, preferably realize the lightweight of heat exchanger 50.In addition, indoor set 100 is owing to the upstream side that is configured in fan 20 heat exchanger 50, so the height dimension of indoor set 100 increases, and becomes the restriction of installing easily.Therefore, preferably make heat exchanger 50 miniaturizations.

For this reason, in this embodiment 1, adopt fin tube type heat exchanger as heat exchanger 50 (front face side heat exchanger 51 and rear side heat exchanger 55), to realize the miniaturization of heat exchanger 50.Specifically, the heat exchanger 50 of this embodiment 1 has a plurality of heat-transfer pipes 57 that separate the stacked a plurality of fins of predetermined gap 56 and these fins 56 of perforation.In this embodiment 1, the left and right directions of housing 1 direction of paper quadrature (among the Fig. 1 with) stacked fin 56.That is, heat-transfer pipe 57 runs through fin 56 along the left and right directions of housing 1 (with the direction of the paper quadrature of Fig. 1).In addition, in this embodiment 1, in order to improve the heat exchanger effectiveness of heat exchanger 50,2 biographies heat pipes 57 have been disposed in the direction of ventilation (width of fin 56) of heat exchanger 50.These heat-transfer pipes 57 are roughly staggered configuration in the vertical section, right side.

Heat-transfer pipe 57 is made up of the pipe of diameter thin (about diameter 3mm～7mm), the cold-producing medium of the heat-transfer pipe 57 of flowing through (indoor set 100 with have the cold-producing medium that uses in the air conditioner of this indoor set 100) be R32, like this, can realize the miniaturization of heat exchanger 50.That is, in heat exchanger 50, heat-transfer pipe 57 inner cold-producing medium and the room airs of flowing through carry out heat exchange via fin 56.Therefore, when adopting thin heat-transfer pipe 57, compare with the heat exchanger that the heat-transfer pipe diameter is thick, under identical circulating mass of refrigerant, the pressure loss of cold-producing medium increases.But R32 compares with R410A, and the evaporation latent heat under uniform temp is big, and available circulating mass of refrigerant is still less brought into play identical ability.Therefore,, used refrigerant amount can be cut down, in heat exchanger 50, the pressure loss can be reduced through using R32.Therefore, through constituting heat-transfer pipe 57 and adopt R32, can make heat exchanger 50 miniaturizations as cold-producing medium with thin pipe.

In the heat exchanger 50 of this embodiment 1,, can realize the lightweight of heat exchanger 50 through forming fin 56 and heat-transfer pipe 57 with aluminum or aluminum alloy.When the weight of heat exchanger 50 did not become the restriction of installing, heat-transfer pipe 57 also can constitute with copper.

(handguard parts and filter)

The indoor set 100 of this embodiment 1 is provided with handguard parts 15, filter 10 at suction inlet 2 places.Handguard parts 15 are from preventing that the purpose that hand touches the fan 20 that is rotating is provided with.Therefore, the shape of handguard parts 15 is arbitrarily, gets final product so long as hand can not touch the shape of fan 20.For example, the shape of handguard parts 15 can be a clathrate, also can be the circle that is made up of a plurality of rings that vary in size.In addition, handguard parts 15 can constitute with materials such as resins, also can constitute with metal material, but when needing intensity, hope to constitute with metal.In addition, consider material and shape that handguard parts 15 are preferably thin as far as possible, intensity is big with the viewpoint that keeps intensity from reducing flowing resistance.Filter 10 is provided with for the inside that prevents dust inflow indoor set 100.Filter 10 releasably is located on the housing 1.In addition, the indoor set 100 of this embodiment 1 has the automatic sweeping machine structure of scavenge filter 10 automatically.

Fig. 6 is the stereogram of framework that the infrared ray sensor of embodiment of the present invention 1 is taken in expression.This Fig. 6 sees near the stereogram the infrared ray sensor 410 from inboard (from the inside of housing 1).

As shown in Figure 6, infrared ray sensor 410 is accommodated in the framework 413.The motor 414 that drives infrared ray sensor 410 (being that infrared ray sensor 410 is rotated to left and right direction specifically) is set above framework 413.Motor 414 for example is a stepper motor.The installation portion 415 that forms as one with framework 413 is fixed on the front lower of housing 1, and like this, infrared ray sensor 410 is installed in housing 1.Be installed under the state of housing 1 motor 414 and framework 413 approximate vertical at infrared ray sensor 410.In the inside of framework 413, infrared ray sensor 410 is installed with the angle of depression of about 24.5 degree down.

Infrared ray sensor 410 is driven by motor 414, can rotation to left and right direction in predetermined angular range (calling this rotation driving movable here).Specifically, as shown in Figure 7.

Fig. 7 is the key diagram of the movable state of the infrared ray sensor in the expression embodiment of the present invention 1.At this, Fig. 7 (a) is the stereogram of expression infrared ray sensor towards the movable state of left end (seeing under the indoor state from indoor set 100, is right-hand end).Fig. 7 (b) is the stereogram of expression infrared ray sensor towards the movable state of central portion.Fig. 7 (c) is the stereogram of expression infrared ray sensor towards the movable state of right-hand end (seeing under the indoor state from indoor set 100, is left end).

Infrared ray sensor 410 is movable to right-hand end (c) through central portion (b) from left end (a), and is if arrived right-hand end (c), then movable in the opposite direction again.Carry out this action times without number, like this, the temperature of temperature detection object range one side detected temperatures detected object in the scanning room, ground about infrared ray sensor 410 one side.

At this, the method for thermographic image data that obtains the wall, floor etc. in room with infrared ray sensor 410 is described.In addition, the control of infrared ray sensor 410 grades be by with the predetermined action sequencing control device 281 (for example microcomputer) carry out.In following explanation, omitted the record of each control that control device 281 carries out.

When obtaining the thermographic image data of wall, floor etc. in room; Make infrared ray sensor 410 movable to left and right direction by motor 414; Per 1.6 degree in the movable angle of motor 414 (rotation of infrared ray sensor 410 drives angle) make infrared ray sensor 410 stop the scheduled time (0.1～0.2 second) in each position.When infrared ray sensor 410 having been stopped, waiting for the scheduled time (than the time of 0.1～0.2 second weak point), be taken into the testing result (thermographic image data) of 8 photo detectors of infrared ray sensor 410 in each position.After being taken into the testing result of infrared ray sensor 410, CD-ROM drive motor 414 (movable angle 1.6 degree) stops then again, is taken into the testing result (thermographic image data) of 8 photo detectors of infrared ray sensor 410 with same action.

Carry out above-mentioned action repeatedly,, calculate the thermographic image data in the surveyed area according to the testing result of the infrared ray sensor 410 at 94 positions of left and right directions.Owing to be in the movable angle of motor 414 per 1.6 degree, make infrared ray sensor 410 stop to be taken into thermographic image data at 94 positions; So the movable range of the left and right directions of infrared ray sensor 410 (angular range that rotation to left and right direction drives) is about 150.4 degree.

Fig. 8 is the key diagram of the vertical luminous intensity distribution angle of visual field of infrared ray sensor in the vertical section of expression embodiment of the present invention 1.This Fig. 8 representes to be installed in indoor set 100 under the ground 1800mm state highly in room 8 the vertical luminous intensity distribution angles of visual field of infrared ray sensor 410 in the vertical section that photo detector longitudinally is arranged in a row.Angle shown in Fig. 8 is the vertical luminous intensity distribution angle of visual field of 1 photo detector for 7 °.

37.5 ° of expressions of angle among Fig. 8 do not get into the zone (distance is installed with the angle of the wall of indoor set 100) of the vertical area of visual field of infrared ray sensor 410.If the angle of depression of infrared ray sensor 410 is 0 °, then this angle is 90 °-4 (photo detector number below horizontal) * 7 ° (the vertical luminous intensity distribution angle of visual field of 1 photo detector)=62 °.Infrared ray sensor 410 in this embodiment 1, because the angle of depression is 24.5 °, so, 62 °-24.5 °=37.5 °.

Through adopting such infrared ray sensor 410, can obtain for example following thermographic image data.

Fig. 9 is one of the thermographic image data that obtains of the infrared ray sensor with this embodiment 1 example.This Fig. 9 representes while making infrared ray sensor 410 movably detect the testing result that in the big or small room of 8 mattings housewife 416 has child 417 life scene in arms to left and right direction, and the result who calculates as thermographic image data thus.

Fig. 9 is in the winter time and the thermographic image data that obtains of date at cloudy day.Therefore, the temperature of window 418 is low, is 10～15 ℃.On the other hand, housewife 416 and child's 417 temperature is the highest.Especially the temperature of housewife 416 and child's 417 the upper part of the body is 26～30 ℃.Like this, movable to left and right direction through making infrared ray sensor 410, for example, can obtain the temperature information of indoor each one.

Therefore, the indoor set 100 of this embodiment 1, the temperature information of indoor each one that obtains according to infrared ray sensor 410, control separately air quantity of each fan 20, up and down blade 70 towards, and left and right sides blade 80 towards.Specifically, the control device 281 that is located in the indoor set 100 has input part, CPU, memory and efferent.Be built-in with indoor design condition judging part, target area determination section, regional wind direction control part in CPU inside.Control device 281 is divided into a plurality of region units to the zone, flooring, replaces each coordinate points of the thermographic image data that is obtained by infrared ray sensor 410 to these a plurality of region units.Like this, can grasp which indoor region unit accurately has the people to exist.

Figure 10 is the example of the indoor set of this embodiment 1 when the flooring area region is divided into a plurality of region unit.

For example, the control device 281 of indoor set 100 is divided into such 15 region units of A1～E3 to indoor ground region.Then, control device 281, according to the thermal source data that obtain from infrared ray sensor 410 control up and down blade 70 and left and right sides blade 80 towards.In addition, control device 281 is controlled the air quantity of each fan 20 according to the thermal source data that obtain from infrared ray sensor 410.

For example, when needs make the air-flow that blows out from blow-off outlet 3 arrive at a distance, the rotating speed of whole fans 20 is increased (air quantity of whole fans 20 is increased), thereby the air quantity that blows out from blow-off outlet 3 is increased.In addition, for example to make the air-flow that blows out from blow-off outlet 3 arrive the utmost point near indoor set 100 local time, the rotating speed of whole fans 20 is reduced (air quantity of whole fans 20 is reduced), thereby the air quantity that blows out from blow-off outlet 3 is reduced.

In addition, for example, even in indoor temperature near during design temperature, also hope sometimes air-conditioning is carried out in the region unit concentrated area that has the people to exist.In this case, to producing the fan 20 of the air-flow that arrives the place (region unit that the someone exists) of hoping central air conditioning, increase its air quantity (being rotating speed).At this moment,, it is turned round with the slow-speed of revolution, it is stopped remaining fan 20.Like this, through controlling the air quantity of each fan 20,, can make the region unit that the air-flow concentrated area arrives has the people to exist though the air-flow integral body that blows out from the blow-off outlet 3 of indoor set 100 is little air quantity.Therefore, can make the temperature environment of the region unit that the someone exists more stable, can realize the running of comfortable, energy-conservation indoor set 100.

In addition, for example, also be hopeful to avoid the situation that the people of the air-flow that blows out from the blow-off outlet 3 of indoor set 100 exists.At this moment, when the place of the air-flow that is hopeful to avoid to blow out from the blow-off outlet 3 of indoor set 100,, its air quantity (being rotating speed) is reduced to producing the fan 20 that arrives the place of hoping to avoid the air-flow that blows out from blow-off outlet 3.Like this, through controlling the air quantity of each fan 20, carry out indoor air conditioning while can suppress to arrive this place from the air-flow that blow-off outlet 3 blows out.Therefore, can be so that hope to avoid the ambient stable in the place of the air-flow that blows out from the blow-off outlet 3 of indoor set 100, and realize the running of comfortable, energy-conservation indoor set 100.

When controlling the air quantity of each fan 20 respectively as described above; As long as the fan 20 of the air-flow that produce to arrive " hoping to concentrate the place of carrying out air-conditioning ", " place of the air-flow that hope is avoided blowing out from blow-off outlet 3 ", as getting final product near the fan 20 in these places.For example, when region unit E3 shown in Figure 10 is equivalent to these places, need only the fan 20 that produces the air-flow that arrives region unit E3 as fan 20C (see figure 3).Through such selection fan 20, can be so that the air-flow integral body that blows out from the blow-off outlet 3 of indoor set 100 towards indoor substantial middle portion, can realize the running of more energy-conservation indoor set 100.

The indoor set 100 of this embodiment 1, as shown in Figure 1, be provided with active silencer mechanism.

Specifically, the silencer mechanism of the indoor set 100 of this embodiment 1 is made up of noise measuring loudspeaker 161, control loudspeaker 181, erasure effect detection loudspeaker 191 and signal processing apparatus 201.Noise measuring loudspeaker 161 is the noise detection devices of running sound (noise) that detect the indoor set 100 of the air-supply sound comprise fan 20.This noise measuring loudspeaker 161 is configured between fan 20 and the heat exchanger 50.In this embodiment 1, be provided in a side of the front face in the housing 1.Control loudspeaker 181 is output control sound output devices to the control sound of noise.This control loudspeaker 181 is configured in the downside of noise measuring loudspeaker 161, the upside of heat exchanger 50.In this embodiment 1, the front face in the wind path middle ground is located at housing 1.It is the erasure effect checkout gears that detect the erasure effect of control sound that erasure effect detects loudspeaker 191.This erasure effect detects loudspeaker 191, is located in order to detect the noise that comes out from blow-off outlet 3 near the blow-off outlet 3.In addition, erasure effect detects loudspeaker 191 and is installed in the mode of not colliding the blow out air that comes out from blow-off outlet 3 and avoids distinguished and admirable position.Signal processing apparatus 201 is the testing results that detect loudspeaker 191 according to noise measuring loudspeaker 161 and erasure effect, makes the control sound generating apparatus of control loudspeaker 181 output control sounds.Signal processing apparatus 201 for example is housed in the control device 281.

Figure 20 is the pie graph of the signal processing apparatus of expression embodiment of the present invention 1.Detecting the electric signal that loudspeaker 191 is imported from noise measuring loudspeaker 161 and erasure effect, after being amplified by microphone amplifier 151, is data signal by A/D converter 152 from analog signal conversion.Data signal after the conversion is imported into FIR wave filter 158 and LMS algorithm unit 159.At FIR wave filter 158; Noise when generation is provided with the place to detect loudspeaker 191 by noise measuring loudspeaker 161 detected noises and arrival erasure effect is with the control signal of mode through revising of amplitude antiphase; After converting analog signal by D/A converter 154 into from data signal; Be exaggerated device 155 and amplify, emit from control loudspeaker 181 as the control sound.

When air conditioner carries out cooling operation etc., shown in figure 19, the area B that heat exchanger 50 and blow-off outlet are 3, because of the cold air temperature descends, so, produce the dewfall that airborne water vapour becomes water droplet.Therefore, on indoor set 100, (figure do not show) such as drip trays that water droplet is not come out from blow-off outlet 3 has been installed near blow-off outlet 3.In addition, the upper reaches of heat exchanger 50 are promptly disposing the zone of noise measuring loudspeaker 161 and control loudspeaker 181, because at the upper reaches in the zone of being freezed by cold air, so do not produce dewfall.

The inhibition method of the running sound of indoor set 100 is described below.The running sound (noise) of the air-supply sound that comprises fan 20 in the indoor set 100 is detected by the noise measuring loudspeaker 161 that is installed between fan 20 and the heat exchanger 50; After becoming data signal via microphone amplifier 151, A/D converter 152, be imported into FIR wave filter 158 and LMS algorithm unit 159.

The tap coefficient of FIR wave filter 158 is upgraded by LMS algorithm unit 159 one by one.At LMS algorithm unit 159, tap coefficient is updated according to formula 1 (h (n+1)=h (n)+2 μ e (n) x (n)), is updated to optimal tap coefficient with error signal e near 0 mode.

In the formula, h: the tap coefficient of wave filter, e: error signal, x: filter input signal, μ: the step size parameter, step size parameter μ is the parameter of the filter coefficient update amount of each sample of control.

Like this; Passed through to be updated the data signal of the FIR wave filter 158 of tap coefficient at LMS algorithm unit 159; Convert analog signal into by D/A converter 154; Be exaggerated device 155 and amplify, be released to the wind path in the indoor set 100 from the control loudspeaker 181 that is installed between fan 20 and the heat exchanger 50 as the control sound.

On the other hand, erasure effect detects loudspeaker 191 in the lower end of indoor set 100, is installed in the lateral wall direction of blow-off outlet 3 with the mode of not colliding the wind of emitting from blow-off outlet 3.This erasure effect detects loudspeaker 191 and detects the sound of the control sound of emitting from control loudspeaker 181 of sening as an envoy to after to the noise jamming of propagating through wind path from fan 20 and coming out from blow-off outlet 3.Owing to import in the error signal of above-mentioned LMS algorithm unit 159 detect loudspeaker 191 detected sounds by erasure effect, so, the tap coefficient of FIR wave filter 158 upgraded near 0 mode with the sound after this interference.As a result, the control sound that has passed through FIR wave filter 158 capable of using is controlled near the noise the blow-off outlet 3.

Like this; In the indoor set that has adopted active noise reduction method 100; Be configured in noise measuring loudspeaker 161 and control loudspeaker 181 between fan 20 and the heat exchanger 50, detect loudspeaker 191 to erasure effect and be installed in the distinguished and admirable position of not colliding to come out from blow-off outlet 3.Therefore; The necessary parts that active noise reduction is not installed in the area B that produces dewfall get final product; Thereby can prevent that water droplet is attached to control loudspeaker 181, noise measuring loudspeaker 161 and erasure effect and detects on the loudspeaker 191, prevent performance muffler deterioration, loudspeaker, micropkonic fault.

In addition, the noise measuring loudspeaker 161 shown in this embodiment 1, control loudspeaker 181 and erasure effect detect the installation site of loudspeaker 191, only are as an example.For example, also can that kind shown in figure 21, detect loudspeaker 191 to erasure effect and be configured between fan 20 and the heat exchanger 50 with noise measuring loudspeaker 161, control loudspeaker 181.In addition, as utilize noise, control sound eliminated the erasure effect testing agency behind the noise, the loudspeaker of having given an example, still, the formations such as acceleration transducer of also available detection hull vibration.In addition, also can catch sound as the disorder of air stream, detect utilizing noise, control sound to eliminate the disorder that the erasure effect behind the noise flows as air.That is, as utilizing noise, control sound to eliminate the testing agency of the erasure effect behind the noise, also can adopt the flow sensor that detects air stream, hotline detector etc.Also can improve micropkonic gain, detect air stream.

In addition; In this embodiment 1; FIR wave filter 158 and LMS algorithm unit 159 have been adopted at signal processing apparatus 201; But, also can be employed in normally used filtering X (filtered-X) algorithm unit in the active noise reduction method, get final product near 0 adaptation signal treatment circuit so long as make erasure effect detect loudspeaker 191 detected sounds.In addition, signal processing apparatus 201 also can not be that adaptation signal is handled, but generates the structure of control sound by fixing tap coefficient.In addition, signal processing apparatus 201 is not a Digital Signal Processing yet, but analog signal processing circuit.

In addition; In this embodiment 1; Put down in writing the situation that configuration produces the heat exchanger 50 that air is cooled off of dewfall, still, be applicable to that also configuration does not produce the situation of heat exchanger 50 of the degree of dewfall; Do not consider whether heat exchanger 50 produces dewfall, all have the effect of the performance degradation that prevents noise measuring loudspeaker 161, control loudspeaker 181 and erasure effect detection loudspeaker 191 etc.
