Again, as shown in Figure 2,, form the air suction inlet 15 of square shape peristome in the substantial middle portion of described decorative panel 14, and at this air suction inlet 15 respectively along the outside on four limits, form elongated OBL 4 air blow-off outlets 16.At described air suction inlet 15 places, be provided with air cleaner 17 along whole suction inlet, be used for removing finely particulate dust that is contained in room air etc., support below this air cleaner 17 whole by cancellate filter hood, and, at described air blow-off outlet 16 places, set the horizontal blade 18 that can change the Air Conditioning blow-off direction up and down.
Particularly, as Fig. 3 after amplifying and shown in Figure 4, the sidewall of the decorative panel periphery (right side among the figure) of the air flue that is communicated with the air blow-off outlet 16 of decorative panel 14 is to be made of with the inclined plane 16b that tilts to the decorative panel outer circumferential side from this vertical plane 16a lower ends downward, be connected below decorative panel 14 the vertical plane 16a that extends to the approximate vertical below.In addition, the sidewall in week (left side among the figure) is that flexure plane 16c that is bloated by downwards decorative panel outer circumferential side and the vertical plane 16d that extends to the approximate vertical below from this flexure plane 16c lower end constitute in the decorative panel of the air flue that is communicated with described air blow-off outlet 16.2 walls of the mutual subtend of above-mentioned shape form along the whole length direction (with the direction of figure paper quadrature) of air blow-off outlet 16, are clipped in the middle air flue of 2 walls and have the function that Air Conditioning flows to blow-off outlet 16 rectified action of flowing and the promotion of changing this flow direction.In this path that promotes to flow, the distance that the promotion of Air Conditioning arrival blow-off outlet 16 is flowed is greatly more than 30mm.
Again, described horizontal blade 18 is extremely shown in Figure 8 as Fig. 5 respectively, sheet material by long chi shape constitutes, crooked a little on its width, crooked medial surface 18a is the front, and lateral surface 18b is the back side, and integraty is provided with conchoidal protuberance 18c, the 18c that protrudes to front face side respectively at the both ends of these horizontal blade 18 length directions, at the limit of each protuberance 18c end, form the connecting pin 18d, the 18d that extend to foreign side along horizontal blade 18 length directions respectively.And, horizontal blade 18 is under the state that is contained on the air blow-off outlet 16, by being positioned at 2 connecting pin 18d, 18d of these blow-off outlet 16 inboards (upstream side that Air Conditioning flows), decorative panel 14 turns and is subjected to connecting supporting freely relatively, by not shown motorized motions, be that center of rotation is rotated with bolster X.
In addition, as one of feature of the present invention, on the front 18a of described horizontal blade 18 inside bend, along these horizontal blade 18 whole length directions be spaced from each other fixed interval (ω p), fixed configurations is useful on a plurality of (being illustrated as 10) cowling panel (19) that the Air Conditioning rectification is used.Width along horizontal blade 18 disposes each cowling panel (19) on roughly orthogonal thereto shape ground, the front of horizontal blade 18 (18a).Shown in the arrow S of Fig. 5, carry out rectification along whole length direction between each cowling panel 19 along the Air Conditioning that flows in the front of horizontal blade 18.
As shown in Figure 6 and Figure 7, the cowling panel space on horizontal blade 18 length directions (ω p) is decided to be 50mm.The height (ω h) that described each cowling panel 19 protrudes from horizontal blade 18 is with more than the 5mm, be advisable below the 30mm, and in this example, best value is that protrusion height (ω h) is decided to be 22.5mm.
When Air Conditioning is blown out below from air blow-off outlet 16, as shown in Figure 4, horizontal blade 18 down, the vertical plane 16d of all sides is overlapping in its back side 8b and the described decorative panel.And when so-called level blows out state, as shown in Figure 3, horizontal blade 18 up, form its front 18b roughly with the parallel state of rake 16b of described decorative panel outer circumferential side wall.
Described fan 20 is arranged on the substantial middle position of body housing 11 inside, be a kind of between shroud 21 and wheel hub 22 the so-called turbofan of clamping blade 23.On the wheel hub 22 of this fan 20, insertion is fixed with the driving shaft 26 of the fan electromotor 25 on the lamina tecti 12 that is contained in body housing 11, utilize the driving force of this fan electromotor 25 to make fan 20 revolutions, will pass out to diametric(al) one side from these fan 20 below inhaled airs thus.Below fan 20, be provided with and flow into the horn mouth 27 that shell 10 interior air are guided fan 20 into from air suction inlet 15.
Have, described heat exchanger (30) is the so-called cross fan heat exchanger that a kind of heat-transfer pipe 32 that is provided with by a plurality of sheet fans 31 that are arranged in parallel and this fan 31 of perforation constitutes again.This heat exchanger 30 will surround around the described fan 20, the tubular structure into rectangle is looked squarely in formation, be connected with off-premises station by not shown refrigerant piping, when cooling operation, work as the aggegation device during as evaporimeter, the warm running of system, to regulate the state of temperature of the air of sending from fan 20.Below this heat exchanger 30, set the drain pan 33 that to accept draining.
That is, in the body housing 11 of aircondition 1, formed the air flue (cowling panel 19) that arrives air blow-off outlet 16 from the air suction inlet of decorative panel 14 through air cleaner 17, horn mouth 27, fan 20 and heat exchanger 30.When operation of air conditioner, in case drive fan 20, flow air flue (cowling panel 19) along horn mouth 27, fan 20 and heat exchanger 30 through the room air that air cleaner 17 flows in the shell 10 from air suction inlet 15, in this heat exchanger 30 and between the cold-producing medium, carry out heat exchange.After adjustment (heating when cooling during cooling operation, the warm running of system), be blown out to the interior space as Air Conditioning from air blow-off outlet 16, the air that carries out this interior space is in harmonious proportion.
More particularly, at first, in Air Conditioning relativity when requiring to make warm running etc. blows out downwards, as preceding shown in Figure 4, make horizontal blade 18 approximate vertical shapes downward, just can make Air Conditioning along the vertical plane 16a of this horizontal blade 18, shown in the arrow S of Fig. 4, blow out to the below of approximate vertical with the decorative panel outer circumferential side of air blow-off outlet 16.
On the other hand, the so-called level when cooling operation etc. blows out in the state, and is shown in Figure 3 as described above, and horizontal blade 18 is upwards rotated, and the front 18a that makes this horizontal blade 18 is roughly parallel with the inclined plane 16b of the decorative panel outer peripheral sidewall of air blow-off outlet 16.Like this, Air Conditioning is along the sidewall of the guide path that is communicated with air blow-off outlet 16, and 18 front 18a bending flows from flexure plane 6c along horizontal blade, and the direction of this streamline produces very big and mild variation.Shown in the arrow S of Fig. 3, the inclined plane 16b of the decorative panel outer circumferential side of process air blow-off outlet 16 and the centre of horizontal blade 18, below ceiling 70,, blow out from air blow-off outlet 16 to approach parallel angle (is about 25 °～35 ° as the angle that constitutes) below ceiling 70.
At this moment, the Air Conditioning that is blown out to the interior space from air blow-off outlet 16 forms jet flow, blows out angle at it and approaches when parallel, to utilize wall attachment effect to make jet flow axially go up bending below ceiling 70.But in this example, as mentioned above, owing on the 18a of the front of horizontal blade 18, be provided with cowling panel 19, lead air communication over commutation plate 19 rectifications of this horizontal blade 18, therefore, this air-flow also is restricted in the part of the left and right sides of air blow-off outlet 16, can not or form eddy current to the side expansion, can only become two-dimensional flow along approximate vertical face (face that comprises section among the figure) and blow out to the interior space.Its result even the two side portions of air blow-off outlet 16 is also the same very fast with the initial velocity that the Air Conditioning of middle body blows out, makes flowing of this air can not arrive ceiling surface 70, and the temperature difference because of room air descends soon.
Therefore, in the ceiling setting-in worker aircondition in the past, air blows out slow part because of wall attachment effect, can make air-flow easily near below the ceiling 70.When cooling operation, utilize horizontal blade 18 up with the blow-off direction relativity of Air Conditioning, if during with respect to about 40～45 ° of the following formation of ceiling 70, air-flow is flowed below ceiling 70, the zone shown in the dotted line of Fig. 2 (D) in, produce the ceiling pollution.But adopt the aircondition 1 of this example, owing on horizontal blade 18, be provided with cowling panel 19, with the mobile rectification of Air Conditioning is two-dimensional flow along vertical plane, therefore, particularly when the cooling operation that requires the Air Conditioning level to blow out, utilize horizontal blade 18 below the relative ceiling 70 of blow-off direction of Air Conditioning, to be close to for example about 25～35 °, just can guarantee air-conditioner efficiency, but and the interior occupant's of decontamination chamber discomfort (sense of ventilating), simultaneously, the Air Conditioning that can suppress this moment again flows below ceiling 70, prevents the generation ceiling pollution problems that in the past existed.
In addition, the present invention is not limited to above-mentioned example, also comprises other various examples.That is, in above-mentioned example, be that cowling panel 19 is arranged on the front 18a of horizontal blade 18 with rectification element, but be not limited to this, for example also cowling panel 19 can be arranged on the inclined plane 16b with the air blow-off outlet 16 of the front 18a subtend of horizontal blade 18.In addition, cowling panel 19 also may not also can set corresponding to the roughly both ends of this air blow-off outlet 16 along the whole length direction configuration of air blow-off outlet 16.
In above-mentioned example, be that horizontal blade 18 is provided on the air blow-off outlet 16, change flowing of Air Conditioning up and down, but also this horizontal blade 18 can be set, only need to utilize the curved shape of the air flue that arrives air blow-off outlet 16 to guide flowing of Air Conditioning.At this moment, air flue itself is exactly a guiding device.
In addition, in above-mentioned example, the present invention uses is 4 direction blowing type airconditions 1 that 4 directions with turbofan blow out the so-called ceiling setting-in of tempered air, but be not limited thereto, for example also blow out the two-way blowing type aircondition of the so-called ceiling setting-in of tempered air applicable to 2 directions with western loo fan.
In sum, ceiling built-in air-conditioning system of the present invention not only can obtain suitable blow-off direction according to operating condition, and can prevent the ceiling of making dirty, therefore, is specially adapted to the place that contamination preventing such as hospital is for example had relatively high expectations.
