Detailed description of the invention
Below, the detailed description of the invention of air conditioner of the present invention (specifically the indoor set of air conditioner) is described.In following each embodiment, for wall indoor unit, the present invention is described.In the figure shown in each embodiment, the shape, size etc. of each unit (or component parts of each unit), also some not identical situation.
Embodiment 1
< essential structure >
Fig. 1 is the profilograph of the indoor set (being called indoor set 100) of the air conditioner representing embodiment of the present invention 1.Fig. 2 is the stereoscopic figure representing this indoor set.In present embodiment 1 and embodiment described later, the front face side of the left side of Fig. 1 as indoor set 100 is described.The structure of indoor set 100 is described based on Fig. 1 and Fig. 2 below.
(unitary construction)
This indoor set 100, by utilizing the freeze cycle making refrigerant circulation, being supplied to indoor Air Conditioning and waiting air-conditioning subject area.Indoor set 100 mainly has housing 1, fan 20 and heat exchanger 50.Housing 1 is formed with the suction inlet 2 for room air is absorbed and the blow-off outlet 3 for Air Conditioning being supplied to 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 disposed in from fan 20 to the wind path of blow-off outlet 3, produces Air Conditioning by carrying out heat exchange between cold-producing medium and room air.By these inscapes, in housing 1, be communicated with wind path (arrow Z).Suction inlet 2 is formed at the upper opening of housing 1.Blow-off outlet 3 is formed at bottom (being specifically, on the downside of the front face of the housing 1) opening of housing 1.Fan 20 is disposed in the downstream of suction inlet 2 and the upstream side of heat exchanger 50, such as, be made up of axial-flow type or mixed flow fan etc.
In addition, indoor set 100 also has control device 281, this control device 281 control the rotating speed of fan 20 and aftermentioned upper and lower blade 70 and left and right blade 80 (when being provided with auxiliary upper and lower blade 71 described later, also comprising auxiliary upper and lower blade 71) towards (angle) etc.In the drawing shown in present embodiment 1 and aftermentioned each embodiment, sometimes also omit the diagram of control device 281.
In the indoor set 100 formed like this, because fan 20 is located at the upstream side of heat exchanger 50, so, with fan 20 is located at blow-off outlet 3 place air conditioner before indoor set compared with, can suppress from blow-off outlet 3 blow out air produce eddy flow, wind speed profile inequality.Therefore, comfortable air-supply can be carried out to air-conditioning subject area.In addition, due to the structure not having fan etc. complicated at blow-off outlet 3 place, so, for the condensation that the intersection at hot gas and cold air during cooling operation produces, also can easily tackle.In addition, because fan motor 30 is not exposed to Air Conditioning and cold air, hot gas, so, long running life can be provided.
(fan)
Usually, there is restriction in the indoor set of air conditioner in installation space, so fan mostly can not be very large.Therefore, in order to obtain required air quantity, and the fan of the multiple modest size of row arrangement.The indoor set 100 of present 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 present common air conditioner, in order to obtain required heat-exchange capacity, fan 20 is preferably roughly 3 ~ 4.In the indoor set of present embodiment 1, fan 20 is all identical shape, and all with the running of identical working speed, thus all fans 20 can obtain roughly the same air output.
By such structure, according to the flowing resistance of Air Quantity Required, indoor set 100 inside, the number of fan 20, shape and size etc. are combined, the best fan design corresponding with the indoor set 100 of plurality of specifications can be obtained.
(horn mouth)
The indoor set 100 of present embodiment 1, configures the horn mouth 5 on pipeline around fan 20.Horn mouth 5 is for guiding air-breathing and the exhaust of fan swimmingly.As shown in Figure 1, the horn mouth 5 of present embodiment 1 is circular from plane.In vertical section, the horn mouth 5 of present embodiment 1 has following shape.Top 5a forms the roughly circular arc that its end expands upward.Central portion 5b is bell-mouthed diameter is certain upstanding portion.Bottom 5c is the roughly circular arc that its end expands downward.Suction inlet 2 is defined by the end (circular arc portion of suction side) of the top 5a of horn mouth 5.
In order to reduce component number and improve intensity, horn mouth 5 such as also can form as one with housing 1.In addition, such as also by modularizations such as horn mouth 5, fan 20 and fan motors 30, it can be made can to load and unload relative to housing 1, like this, can maintainability be improved.
In present embodiment 1, the end (circular arc portion of suction side) of the top 5a of horn mouth 5, relative to the circumference of the opening surface of horn mouth 5, is identical shape.That is, in the direction of rotation centered by the rotating shaft 20a of fan 20, horn mouth 5 does not have the structure of breach, rib etc., is the uniform shape with axial symmetry.
By forming horn mouth 5 like this, because the end (circular arc portion of suction side) of the top 5a of horn mouth 5 is uniform shapes relative to the rotation of fan 20, so, as the inlet flow of fan 20, also realize uniform air-flow.Therefore, the noise produced because of the bias current of the inlet flow of fan 20 can be reduced.
(demarcation strip)
As shown in Figure 2, the indoor set 100 of present embodiment 1, is provided with demarcation strip 90 between adjacent fan 20.These demarcation strips 90 are arranged between heat exchanger 50 and fan 20.That is, the wind path between heat exchanger 50 and fan 20 is divided into multiple wind path (in present embodiment 1 being 3).Because demarcation strip 90 is arranged between heat exchanger 50 and fan 20, so the end of the side connected with heat exchanger 50 is the shape along heat exchanger 50.Specifically, as shown in Figure 1, indoor the front face side of machine 100 to the vertical section of rear side (that is, from the vertical section of indoor set 100 viewed from right side.Hereinafter referred to vertical section, right side) in, heat exchanger 50 is configured to roughly A shape.Therefore, demarcation strip 90 is also roughly A shape by the end of heat exchanger 50 side.
The position of the end by fan 20 side of demarcation strip 90, such as, can determine as follows.When adjacent fan 20 is enough far away apart, under suction side does not produce interactional situation, the end by fan 20 side of demarcation strip 90 extends to the exit face of fan 20.But, adjacent fan 20 at a distance of closer and suction side produce influence each other time, and, when the shape of the end (circular arc portion of suction side) of the top 5a of horn mouth 5 can be formed enough large, the end by fan 20 side of demarcation strip 90 also can with do not affect adjacent wind path mode (with adjacent fan 20 in suction side not interactional mode) extend to the upstream side (suction side) of fan 20.
Demarcation strip 90 can be formed by various material.Such as, demarcation strip 90 can be formed with the metal of steel, aluminium etc.In addition, such as also demarcation strip 90 can be formed with resin etc.But, because heat exchanger 50 is high temperature when supplying heat run, so, when demarcation strip 90 is the material formation with low melting points such as resins, very little space can be formed between demarcation strip 90 and heat exchanger 50.When demarcation strip 90 is the high materials of the melting point such as aluminium, steel, also demarcation strip 90 and heat exchanger 50 phase ground connection can be configured.When heat exchanger 50 is such as fin tube type heat exchangers, also demarcation strip 90 can be inserted between the fin of heat exchanger 50.
As mentioned above, the wind path between heat exchanger 50 and fan 20 is divided into multiple wind path (in present embodiment 1 being 3).In this wind path, namely, sound-absorbing material is set on demarcation strip 90, housing 1 etc., the noise produced in pipeline can be reduced.
In addition, these divided wind paths, from plane, form the roughly quadrangle that the length of side is L1 and L2.That is, the width of divided wind path is L1 and L2.Therefore, such as, the air quantity that the fan 20 being arranged on the roughly quadrangle inside formed by L1, L2 produces effectively by be positioned at fan 20 downstream, the heat exchanger 50 in region that surrounded by L1, L2.
Like this, by the wind path in housing 1 is divided into multiple wind path, even if there is cycle composition in the flow field that fan 20 is formed in downstream, the air blown out from each fan 20 freely can not move in the length direction of indoor set 100 (direction orthogonal with Fig. 1 paper).Therefore, the air that blows out of fan 20 by this fan 20 downstream, the heat exchanger 50 in region that surrounded by L1, L2.As a result, the inequality of the air volume adjustment of indoor set 100 length direction (direction orthogonal with Fig. 1 paper) flowing into whole heat exchanger 50 can be suppressed, thus there is high heat exchange performance.In addition, by separating in housing 1 with demarcation strip 90, between mutually adjacent fan 20, the interference of the eddy flow that can prevent adjacent fans 20 from producing.Therefore, the fluid energy losses produced because of the mutual interference of eddy flow can be suppressed, the pressure loss of indoor set 100 can be reduced while improving wind speed profile.In addition, each demarcation strip 90 is not necessarily formed with one block of plate, also can be formed with plurality of plates.Such as, also in front face side heat exchanger 51 side and rear side heat exchanger 55 side, demarcation strip 90 can be divided into two.Certainly, the position that is bonded with each other forming each plate of demarcation strip 90 is preferably very close to each other.By demarcation strip 90 is divided into multiple assembleability improving demarcation strip 90.
(fan motor)
Fan 20 drives rotation by fan motor 30.The fan motor 30 adopted can be inner-rotor-type, also can be external-rotor-type.When fan motor 30 of external-rotor-type, also adopt hub 21 all-in-one-piece structure (hub 21 has rotor) of rotor and fan 20.In addition, by the size making the size of fan motor 30 be less than the hub 21 of fan 20, can prevent the air-flow to fan 20 generates from causing damage.In addition, the inside of motor configurations at hub 21, direction of principal axis size can be reduced.By fan motor 30 and fan 20 being made the structure of easily handling, cleaning property also improves.
By adopting the high DC brushless motor of cost compare as fan motor 30, can raise the efficiency, improve controlling and realize long lifetime.But even if adopt the motor of other form, also can meet the elementary function as air conditioner, this is self-evident.
In addition, the circuit of the driving of fan motor 30, can be integrated with fan motor 30 one-tenth, also can form in outside and implement dust-proof, fireproof countermeasure.
Fan motor 30 is arranged on housing 1 by motor support 16.In addition, if fan motor 30 is become the boxlike (fan 20, framework, fan motor 30 etc. integral and be componentized) for CPU cooling, become the structure that can load and unload relative 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 at the Inner Constitution of fan motor 30, also can in outside.
(motor support)
Motor support 16 has fixed part 17 and support unit 18.Fixed part 17 is provided with fan motor 30.Support unit 18 is the parts for fixed part 17 being fixed on housing 1.Support unit 18 is such as shaft-like, such as radially extended from the peripheral part of fixed part 17.As shown in Figure 1, the support unit 18 of present embodiment 1 is extended in general horizontal direction.
(heat exchanger)
The heat exchanger 50 of the indoor set 100 of present embodiment 1 is configured in the downwind side of fan 20.This heat exchanger 50 such as can adopt fin tube type heat exchanger etc.As shown in Figure 1, in vertical section, right side, heat exchanger 50 is split by line of symmetry 50a.Line of symmetry 50a is divided into left and right directions the scope that arranges of the heat exchanger 50 in this section in substantially central portion.That is, front face side heat exchanger 51 is configured in front face side (in Fig. 1 on the left of paper) relative to line of symmetry 50a, and rear side heat exchanger 55 is configured in rear side (in Fig. 1 on the right side of paper) relative to line of symmetry 50a.Front face side heat exchanger 51 and rear side heat exchanger 55 are configured in housing 1 in this wise: the interval between front face side heat exchanger 51 and rear side heat exchanger 55 expands relative to the flow direction of air, namely, in vertical section, right side, the section shape of heat exchanger 55 is in roughly A shape.That is, front face side heat exchanger 51 and rear side heat exchanger 55 configure in the mode with inclination relative to the flow direction of the air supplied from fan 20.
In addition, the feature of heat exchanger 50 is, 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 present embodiment 1, in 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 length etc. of depth direction (in the Fig. 1) 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.
By forming heat exchanger 50 like this, with fan is located at blow-off outlet air conditioner before indoor set compared with, the air blown out from blow-off outlet 3 can be suppressed to produce eddy flow, suppress the inequality of wind speed profile.In addition, by forming heat exchanger 50 like this, 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, respectively by the air of front face side heat exchanger 51 and rear side heat exchanger 55 when collaborating, the air behind this interflow bends towards front face side (blow-off outlet 3 side).Therefore, air-flow need not be made to bend sharp near blow-off outlet 3, the pressure loss near blow-off outlet 3 can be reduced.
In addition, in the indoor set 100 of present embodiment 1, be from rear side towards effluent is dynamic above from the flow direction of the air of rear side heat exchanger 55 outflow.Therefore, the indoor set 100 of present embodiment 1, with in vertical section, right side heat exchanger 50 be configured to roughly v shape time compared with, the flowing that have passed the air after heat exchanger 50 more easily bends.
Indoor set 100, owing to having multiple fan 20, so weight easily increases.When indoor set 100 increases the weight of, just require that there is some strength for the wall installing indoor set 100, become the restriction of installing.Therefore, the lightweight of heat exchanger 50 is preferably realized.In addition, indoor set 100 owing to fan 20 being configured in the upstream side of heat exchanger 50, so the height dimension of indoor set 100 increases, and easily becomes the restriction of installing.Therefore, preferably make heat exchanger 50 miniaturized.
For this reason, in present 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 present embodiment 1 has the multiple heat-transfer pipes 57 separating the stacked multiple fins 56 of predetermined gap and these fins 56 through.In present embodiment 1, the left and right directions (direction orthogonal with paper in Fig. 1) of housing 1 stacked fin 56.That is, heat-transfer pipe 57 runs through fin 56 along the left and right directions (direction orthogonal with the paper of Fig. 1) of housing 1.In addition, in present embodiment 1, in order to improve the heat exchanger effectiveness of heat exchanger 50, be configured with 2 biographies heat pipes 57 in the direction of ventilation (width of fin 56) of heat exchanger 50.These heat-transfer pipes 57 are roughly staggered configuration in vertical section, right side.
Heat-transfer pipe 57 is made up of the pipe of diameter thin (diameter about 3mm ~ 7mm), the cold-producing medium (at indoor set 100 and have the cold-producing medium used in the air conditioner of this indoor set 100) flowing through heat-transfer pipe 57 is R32, like this, the miniaturization of heat exchanger 50 can be realized.That is, in heat exchanger 50, the cold-producing medium and the room air that flow through heat-transfer pipe 57 inside carry out heat exchange via fin 56.Therefore, when adopting thin heat-transfer pipe 57, compared with the heat exchanger that heat-transfer pipe diameter is thick, under identical circulating mass of refrigerant, the pressure loss of cold-producing medium increases.But R32 and R410A compares, evaporation latent heat is at the same temperature large, can play identical ability with less circulating mass of refrigerant.Therefore, by using R32, refrigerant amount used can be cut down, in heat exchanger 50, can the pressure loss be reduced.Therefore, by forming heat-transfer pipe 57 with thin pipe and adopting R32 as cold-producing medium, heat exchanger 50 can be made miniaturized.
In the heat exchanger 50 of present embodiment 1, by forming fin 56 and heat-transfer pipe 57 with aluminum or aluminum alloy, the lightweight of heat exchanger 50 can be realized.When the weight of heat exchanger 50 does not become the restriction of installing, heat-transfer pipe 57 also can be formed with copper.
