The fin 51 of shape is transmitted and is used as heat exchanger plate, efficiently carries out the cooling of air.Fin 51 is not to interfere air stream dynamic
The direction flowed with air of mode be set in parallel, heat-transfer pipe 52 is arranged on the direction orthogonal with the direction of air circulation.
In the blow-off outlet 3 of framework 1, equipped with wind direction alteration board 7 and the rear being located behind above and below the front side for being located at front
Wind direction alteration board 8 above and below side, is able to change the wind direction of air along the vertical direction.
The lower section of wind direction alteration board 7 above and below front side is equipped with downside left and right wind direction and changes plate 9.Downside left and right wind direction becomes
More plate 9 can change in left-right direction has carried out heat by back sweep portion 50b, front rake 50c and back sweep portion 50d

Indoor unit 100 executes operation start using remote controller etc., operating stops, and can carry out temperature, air quantity, wind direction
Setting etc., and its control system is same as the prior art.In addition, the outdoor unit 102 of heat exchange is also same as the prior art.
As shown in Figure 3A like that, each upside left and right wind direction change plate 20 heat-transfer pipe 52 airflow downstream, Air Temperature
The degree region relatively low compared to surrounding, two openings 21a, 21b being gradually reduced with width from air-flow upstream to downstream.With
Under, opening 21a, 21b are known as slit 21a, 21b corresponding to its shape.In addition, in figure 3 a, upper right is air-flow upstream, left
It is down airflow downstream.
So-called " airflow downstream of heat-transfer pipe 52 ", refers to the area for flowing through the downstream side that the air around heat-transfer pipe 52 is passed through
Domain.Since heat-transfer pipe 52 is there are multiple, so there is also multiple for airflow downstream.So-called " slit ", refers to the opening of elongated shape.
So-called opening portion refers to that a face from upside left and right wind direction change plate 20 penetrates through hole, the notch etc. to another face.It is so-called to make
The width of opening is gradually reduced, and is opening 21a, the 21b per certain unit area for instigating upside left and right wind direction change plate 20
The ratio of opening area is gradually reduced.
For example, as shown in fig. 3b, considering 4 hypothetical rectangles as shown in dotted line with the superposition of end gap of slit 21b
28a,28b,28c,28d.They are the squares of the same area that configuration is successively abutted from the air-flow upstream side of slit 21b towards downstream side
Shape.For the mode of configuration, firstly, matching in such a way that the ratio of the opening of the hypothetical rectangle 28a slit 21b for being included is maximum
Set hypothetical rectangle 28a.Then, adjacently with hypothetical rectangle 28a, with the ratio of the opening of the hypothetical rectangle 28b slit 21b for being included
Example maximum mode configures hypothetical rectangle 28b.Equally configure in order hypothetical rectangle 28c, hypothetical rectangle 28d.In this way, occupying vacation
Think that the area ratio first of the opening of the slit 21b of the area of rectangle 28a is big, then, occupies the slit 21b of hypothetical rectangle 28b
Opening ratios it is second largest, then, the opening ratios for occupying the slit 21b of hypothetical rectangle 28c are the third-largest, and opening ratios are the smallest
It is the opening for occupying the slit 21b of the hypothetical rectangle 28d positioned at most downstream side.The relationship is also the same for slit 21a.
In order to illustrate the effect of such slit 21a, 21b, using Fig. 4, Fig. 5, there is no the existing skill of slit 21a, 21b
For the left and right wind direction change plate 40 of art, illustrate the mechanism for generating moisture condensation.
In Fig. 4, the intermediate temperature region 41 for marking oblique line is the low of the air flowing cooled down by heat-transfer pipe 52
The region of the air flowing of the temperature of the centre in the high-temperature region 42 that temperature region 43 is flowed with the air close to room temperature.Discontinuously
The boundary thermoisopleth in line expression low temperature region 43 and intermediate temperature region 41.Dotted line indicates high-temperature region 42 and medium temperature
The boundary thermoisopleth in region 41.Therefore, dashed line is the temperature thermoisopleth lower than dotted line.The reason of flowing of air is so bent
It is, drain pan 6 is configured in the lower section of heat-transfer pipe 52, in the constricted flow of this air.
As shown in Figure 4, the air themperature of the intermediate temperature region 41 of the airflow downstream in multiple heat-transfer pipes 52, with
The air themperature in the high-temperature region 42 flowed by the air of the mutual centre of heat-transfer pipe 52 is compared, relatively lower.Pass through
The air of the intermediate temperature region 41 is contacted with the surface of left and right wind direction change plate 40, and the surface that left and right wind direction changes plate 40 is cold
But.In left and right wind direction change plate 40, heat transfer occurs, low temperature portion reaches the left and right wind direction that the air in high-temperature region 42 passes through
The region of plate 40 is changed, the surface temperature in the region reduces.When the surface temperature in the region that the air in high-temperature region 42 passes through
When for below the dew-point temperature of the air in high-temperature region 42, moisture condensation is generated.
In Fig. 5, oblique line portion is the moisture condensation region 47 that speed is zero or more, i.e. generation moisture condensation that condenses.As shown in Figure 5 that
Sample, the surface of the left and right wind direction change plate 40 near passing through using the air-flow rear portion of heat-transfer pipe 52 by the streamline 45 put
Moisture condensation is not generated, generates moisture condensation in surrounding region.
By Fig. 4 and Fig. 5 it is found that left and right wind direction change plate 40 on moisture condensation the main reason for be: by heat-transfer pipe 52 into
Air cooling, compared to surrounding relative low temperature of having gone is contacted with left and right wind direction change plate 40, and left and right wind direction changes 40 part of plate
It is cooled；And expanded by the cooling region of the heat transfer in left and right wind direction change plate 40, what generation was contacted with surface becomes empty
The dew point of gas part below.According to above Dew Producing Mechanism it is found that in order to inhibit the moisture condensation on left and right wind direction change plate 40, only
Left and right wind direction change plate 40 is wanted not to be locally cooled, as long as that is, left and right wind direction changes plate 40 as far as possible not and by heat-transfer pipe 52
Cooling air contact.
Thus, in the present invention, as shown in Figure 3A like that, it is being located at the airflow downstream of heat-transfer pipe 52, upside left and right wind
The region flowed to the air of the relative low temperature of change plate 20 is provided with slit 21a, 21b.The sky of relative low temperature can be reduced as a result,
The area that gas is contacted with upside left and right wind direction change plate 20.In turn, the region for transmitting heat tails off, also it can be expected that inhibiting heat transfer
Effect.
In addition, as shown in Figure 5, the air cooled down by heat exchanger 50 from air-flow upstream to downstream gradually with
The relatively warm air mixing of surrounding, air themperature distribution become balanced, and the region that condenses is more toward downstream with regard to smaller.Thus, lead to
Crossing is gradually reduced slit width from air-flow upstream to downstream as slit 21a, 21b, and available moisture condensation prevents effect, simultaneously
Can the reduction that wind direction changes ability be inhibited small.
According to such composition, it can reduce and generate the risk of moisture condensation in upside left and right wind direction change plate 20, in addition producing
The occasion for having given birth to moisture condensation can also reduce moisture condensation amount.
As described above, according to embodiment 1, upside left and right wind direction changes plate 20 at the rear portion of heat-transfer pipe 52
, compared with the air contact of surrounding relative low temperature region, having from air-flow upstream towards downstream is gradually reduced slit width
Slit 21a, 21b.Thus, it is possible to provide even if in the case where left and right wind direction change plate 20 in upside is located at the heat exchanger 50 of finned tube type
Occasion near trip is also difficult to generate the indoor unit 100 of moisture condensation.
In addition, as described above, the shape of slit 21a, 21b are confirmed as being suitble to the distribution of air themperature, but in basis
The position of upside left and right wind direction change plate 20 and the occasion that makes the distribution shape of air themperature different, in multiple upside left and right wind
Into change plate 20, the shape of slit 21a, 21b be can also be different.In addition, in the embodiment 1 tool there are two slit 21a,
21b, but can correspond to the distribution of air themperature arbitrarily to determine the quantity of slit.
In addition, the downside left and right wind direction change plate 9 in embodiment 1 is configured in back sweep portion 50b, front rake
The downstream side of the heat-transfer pipe 52 of 50c and back sweep portion 50d, but due to the distance away from heat-transfer pipe 52, the sky of relative low temperature
Gas is mixed with warm air, it is therefore difficult to generate local moisture condensation.Thus, although being not provided in downside left and right wind direction change plate 9
Slit still generates the distribution of air themperature in the configuration relation due to heat-transfer pipe 52 and downside left and right wind direction change plate 9 and holds
It is also easy to produce the occasion of moisture condensation, plate 9 can also be changed in downside left and right wind direction and slit is set.

The figure of upside left and right wind direction change plate 20a involved in embodiment 2 is watched in face.
As shown in Figure 6, upside left and right wind direction change plate 20a heat-transfer pipe 52 airflow downstream, compared with around
The region of the air contact of relative low temperature, has two notch for being gradually reduced the width of notch from air-flow upstream to downstream
22a,22b.So-called " notch " refers to the opening portion opened wide until the end face of upside left and right wind direction change plate 20a.Implementing
In the upside left and right wind direction change plate 20 of mode 1, slit 21a, 21b are the through holes for not being open to end face, and notch 22a, 22b
Then open wide the end face until the air-flow upstream side of upside left and right wind direction change plate 20a.The so-called width for making notch is gradually reduced, and is
The ratio of the opening area of notch 22a, 22b of every imaginary unit's area is instigated to be gradually reduced towards downstream side.In addition, such as embodiment party
As illustrating in formula 1, at this point, the quantity of notch is also any, however it is not limited to 2, be also possible to 1 or 3 or more.
According to such composition, upside left and right wind direction when can reduce refrigeration operation changes the cooling of plate 20a, and inhibits
Upside left and right wind direction changes the heat transfer in plate 20a.It can reduce moisture condensation risk compared with prior art as a result, in addition generating
The occasion of moisture condensation can also reduce moisture condensation amount.
In turn, same as embodiment 1, by making the width of notch 22a, 22b gradually from air-flow upstream side towards downstream side
Reduce, to have the effect of reducing moisture condensation risk and wind direction change ability is inhibited to reduce.
In addition, the upstream end of upside left and right wind direction change plate 20a is that air themperature is distributed least balanced and is easy to produce knot
The position of dew, but by carrying out cutting process to upstream end, to have the effect of further decreasing moisture condensation risk.
(embodiment 3)

As shown in Figure 7, upside left and right wind direction change plate 20b heat-transfer pipe 52 airflow downstream, compare around phase
To the region of the air flowing of low temperature, there are the multiple circular through holes for being gradually reduced diameter towards downstream from air-flow upstream
23.The so-called diameter for making circular through hole 23 is gradually reduced, and is the aperture efficiency for instigating the through hole 23 of every imaginary unit's area
Example is gradually reduced towards downstream side.In addition, circular through hole 23 is configured to 2 column, but the columns of through hole configuration at this time is any
, 2 column are not limited to, also can be configured to the columns of 1 column or 3 column or more.
According to such composition, upside left and right wind direction when can reduce refrigeration operation changes the cooling of plate 20b, and inhibits
Upside left and right wind direction changes the heat transfer in plate 20b.Moisture condensation risk can be reduced compared with prior art as a result, even if in addition existing
The occasion of moisture condensation also can reduce moisture condensation amount.
In turn, same as embodiment 1, by subtracting the opening ratios of through hole 23 gradually

(embodiment 4)
Embodiment 4 is slit 21a, 21b in alternate embodiments 1 and distinguishes in the airflow downstream region of heat-transfer pipe 52
Being arranged has the example of the circular through hole 24 of multiple same diameters.Fig. 8 is watched from side viewing involved in embodiment 4
The figure of upside left and right wind direction change plate 20c.
As shown in Figure 8, upside left and right wind direction change plate 20c heat-transfer pipe 52 airflow downstream, compare around phase
To the region of the air flowing of low temperature, there are the multiple circular perforations for gradually decreasing distributed quantity towards downstream from air-flow upstream
Hole 24.Diameter configured with multiple through holes 24 is identical, but its quantity (distribution proportion) more toward downstream and it is fewer.It is,
The opening ratios of the through hole 24 of every imaginary unit's area are gradually reduced towards downstream side.In addition, circular through hole 24 is configured to 2
Column, but the columns of the configuration of through hole is also arbitrary at this time, is not limited to 2 column, also can be configured to 1 column or 3 column are above
Columns.
According to such composition, upside left and right wind direction when can reduce refrigeration operation changes the cooling of plate 20c, and inhibits
