Abstract

PROBLEM TO BE SOLVED: To sufficiently supply air-conditioning air to every floors even in a small amount of air by installing an air conditioner for four floors at the center of a ceiling in one room without using a damper unit or a duct as in the conventional way.SOLUTION: An air conditioner for four floors that is installed at the center of a ceiling in one room includes an adjustable direction adjusting blades that blow air-conditioned air to each direction of four floors in the room, an air volume adjusting vane that is provided in the upstream of each of the direction adjusting blades to adjust an air-conditioned air volume by adjustable opening, and a leading opening for leading an indoor air to a position out of an air route between the direction adjusting blade and air volume adjusting vane. Blow-out air velocity becomes high specially when the opening of the air volume adjusting vane is smaller, thereby increasing the volume of air blown out from the direction adjusting blade by sucking more leading air. Even when the opening of the air volume adjusting vane is small, an air-conditioning air flow is independently and individually controlled for each of four floors so that air-conditioned air necessary for each of the four floors may arrive at the floors.

Description

本発明は、一つの室内に４床が存在する空気調和機、更に詳しくは、４床に必要な空調空気を給気する４床用空気調和機に関するものである。   The present invention relates to an air conditioner having four beds in one room, and more particularly to a four-bed air conditioner for supplying conditioned air necessary for the four beds.

従来、病院等において、一つの室内を４等分したスペースに、それぞれ１台の床（ベッド)を配置する４床病室が多い。これらの４床病室のそれぞれの床での使用者には好む空調に個人差があり、このため４床病室では各床毎に個別空調制御を行うことがある。
４床病室の個別空調制御の例としては、本出願人らによって特許文献１が提案されているが、これは１台の４床用空気調和機の吹出部に内蔵した４分岐ダンパユニットを設け、４床用空気調和機からの空調空気を分岐して、各床近傍までダクトを延ばして、各床の天井に取り付けたダクトからの吹出口から送風し、前記ダンパユニットを制御して各床毎の個別空調制御を行っていた。 Conventionally, in hospitals and the like, there are many four-bed hospital rooms in which one floor (bed) is arranged in a space obtained by dividing one room into four equal parts. There are individual differences in the air conditioning preferred by users on the respective floors of these four-bed hospital rooms. For this reason, individual air-conditioning control may be performed for each floor in the four-bed hospital rooms.
As an example of individual air-conditioning control for a four-bed hospital room, Patent Document 1 has been proposed by the present applicants, and this is provided with a four-branch damper unit built in the blow-out part of a single four-bed air conditioner. Branches the conditioned air from the four-bed air conditioner, extends the ducts to the vicinity of each floor, blows air from the air outlets from the ducts attached to the ceiling of each floor, and controls the damper unit to control each floor Individual air conditioning control was performed.

しかし、特許文献１のようなダンパユニットとダクトの組み合わせの個別空調制御は、個別制御が可能であるが、天井内にダクト工事が必要であり、各床の天井に取り付けるダクトや吹出口が必要であり、また、空気調和機に４分岐ダンパユニットを内蔵するとなると、４分岐ダンパユニット自体のサイズが大きいので大きなスペースを必要とするといった問題点があった。   However, the individual air-conditioning control of the combination of the damper unit and the duct as in Patent Document 1 can be individually controlled, but the duct work is necessary in the ceiling, and the duct and the air outlet attached to the ceiling of each floor are necessary. In addition, when the 4-branch damper unit is built in the air conditioner, there is a problem that a large space is required because the size of the 4-branch damper unit itself is large.

特開２００４−３６０９７８号公報JP 2004-360978 A

本発明は、上記の問題点に鑑みてなされたもので、その課題は、４床用空気調和機において、従来のようにダンパユニットやダクトを用いること無しに、一つの室内の天井中央に４床用空気調和機を据え付け、この４床用空気調和機によって、各床へ十分な空調空気が到達するようにする４床用空気調和機を提供しようとするものである。また、別の課題は、各床への空調空気の風量が少なくなった場合でも、各床へ十分な空調空気が到達するようにする４床用空気調和機を提供しようとするものである。   The present invention has been made in view of the above-mentioned problems, and its problem is that, in a four-bed air conditioner, the center of the ceiling of one room can be used without using a damper unit or a duct as in the prior art. It is intended to provide a four-bed air conditioner in which a floor air conditioner is installed and sufficient conditioned air reaches each floor by the four-bed air conditioner. Another problem is to provide a four-bed air conditioner that allows sufficient conditioned air to reach each floor even when the volume of conditioned air to each floor decreases.

上記の課題を解決するために、請求項１の発明は、一つの室内の天井中央に据え付ける４床用空気調和機であって、一つの室内の４床の各方向に向けて、各方向毎に空気調和された空気を吹出す吹出口を設け、該吹出口毎の上流に開度が調整可能で空気調和された空気量を調整する風量調整ベーンを設け、該風量調整ベーンはそれぞれ独立して調整を可能にし、４床方向毎に個別に空調気流を制御することができることを特徴とする４床用空気調和機である。
請求項２の発明は、請求項１に記載の４床用空気調和機において、前記吹出口には方向調整ブレードを設け、該方向調整ブレードによって吹出方向を調整可能にし、４床方向毎に個別に空調気流を制御することができることを特徴とする。 In order to solve the above problems, the invention of claim 1 is a four-bed air conditioner installed at the center of a ceiling in one room, and is directed to each direction of the four floors in one room. Provided with an air outlet that blows out air-conditioned air, and provided with an air volume adjusting vane that adjusts the air volume that is adjustable in air opening upstream of each air outlet, and the air volume adjusting vanes are independent of each other. The four-bed air conditioner is characterized in that the air-conditioning airflow can be individually controlled for every four floor directions.
According to a second aspect of the present invention, in the four-bed air conditioner according to the first aspect, the air outlet is provided with a direction adjusting blade, the blowing direction can be adjusted by the direction adjusting blade, and the air flow is individually provided every four floor directions. The air-conditioning airflow can be controlled.

請求項３の発明は、請求項１又は請求項２に記載の４床用空気調和機において、前記吹出口と風量調整ベーンとの風道を外れた位置に室内空気を誘引する誘引開口を設け、前記風量調整ベーンの開度が小さい場合ほど誘引空気を多く吸い込むようにして吹出口からの吹出空気の量を多くし、前記風量調整ベーンの開度が小さくても各床に必要な空気調和された空気が届くようにして４床毎に個別に空調気流を制御することができることを特徴とする。   According to a third aspect of the present invention, in the four-bed air conditioner according to the first or second aspect, an induction opening for attracting room air is provided at a position outside the air passage between the air outlet and the air volume adjusting vane. The smaller the opening of the air volume adjustment vane, the greater the amount of air drawn from the outlet by sucking in more air, and the air conditioning required for each floor even if the opening of the air volume adjustment vane is small. The air-conditioning airflow can be individually controlled every four floors so that the delivered air can reach.

以上説明したように、請求項１の４床用空気調和機の発明によれば、従来のようにダンパユニットやダクトを用いることなしに、一つの室内の天井中央に４床用空気調和機を据え付けるだけでよく、簡単な工事で一つの室内の４床の各方向に向けて空気調和が可能になり、保守も容易でより的確に個別空調制御が可能な４床用空気調和機とすることができる。
請求項２の４床用空気調和機の発明によれば、請求項１の効果に加えて、４床の各方向の調整が可能であるので、適切に４床毎に向けての空気調和が可能になる。
請求項３の４床用空気調和機の発明によれば、請求項１又は請求項２の効果に加えて、各床への空調空気の風量が少なくなった場合でも、風量調整ベーン開度が小さいほど吹出風速は大きくなることと相俟って、誘引空気を多く吸い込むようになり吹出口からの吹出空気の量を多くし、これらの相乗効果により、十分な空調空気が各床まで到達し、各床への個別空調制御がより的確に行うことができる。
また、従来のファンコイルユニットは、冷房時に風量が少ないと吹出箇所が局部的に低温となりすぎ、その病室患者等に不快感を与えたり、結露を発生する可能性があるが、誘引気流との混合により吹出温度は高くなり、低温気流による不快感を防止でき、結露も生じない。 As described above, according to the invention of the four-bed air conditioner of claim 1, the four-bed air conditioner is installed in the center of the ceiling of one room without using a damper unit or a duct as in the prior art. It is only necessary to install it, and air conditioning can be performed in each direction of four floors in one room with simple construction, and maintenance is easy, and a four-bed air conditioner that can perform individual air conditioning control more accurately. Can do.
According to the four-bed air conditioner of the second aspect, in addition to the effect of the first aspect, the adjustment of each direction of the four floors is possible. It becomes possible.
According to the invention of the four-bed air conditioner of claim 3, in addition to the effect of claim 1 or 2, even if the air volume of the conditioned air to each floor is reduced, the air volume adjusting vane opening degree is Combined with the fact that the smaller the smaller, the higher the blown air speed, so that more air is drawn in and the amount of air blown out from the air outlet is increased. By these synergistic effects, sufficient conditioned air reaches each floor. Individual air conditioning control for each floor can be performed more accurately.
In addition, the conventional fan coil unit, when the air volume during cooling is low, the blowout part becomes too cold locally, which may cause discomfort to the patient in the hospital room or the like, and may cause condensation. Mixing increases the blowing temperature, prevents discomfort caused by low-temperature airflow, and does not cause condensation.

[吹出部５]
本発明の特徴部分である吹出部５について説明する。
前記吹出部５には、図２に示されるように、概略、ダクト２の給気ダクト２２(図５)の給気口２３(図２,図５)から吹出口１２２までのガイド通路５１が設けられ、ガイド通路５１の空気の流れの上流にはベーン５５が、下流にはブレード５２が設けられ、ガイド通路５１の空気流の経路上から外れた位置に誘引空気口５８が配置されている。 [Blowout part 5]
The blowing part 5 which is a characteristic part of the present invention will be described.
As shown in FIG. 2, a guide passage 51 from the air supply port 23 (FIG. 2, FIG. 5) of the air supply duct 22 (FIG. 5) of the duct 2 to the air outlet 122 is provided in the blowout portion 5. A vane 55 is provided upstream of the air flow in the guide passage 51 and a blade 52 is provided downstream, and an induction air port 58 is disposed at a position off the air flow path of the guide passage 51. .

[ブレード]
図４(図３)に示すように、吹出部５は、ガイド経路５１(図２)の下流の先端の室内天井位置には吹出口１２２を設け、吹出口１２２の直前でガイド経路５１の下流には吹出風向を調整するブレード５２を設けてある。
このブレード５２の空気流案内方向は、４つの吹出区画(Ｃ１，Ｃ２，Ｃ３，Ｃ４)で独立して調整可能なように、それぞれ調整ツマミ５３が側枠１３に設けられている。すなわち、図４では、図面の左上の吹出区画Ｃ１のブレード５２ａは、ベッドＢ１の方向に給気ＳＡが到達するように調整ツマミ５３ｂで調整し、同様に、右上の区画Ｃ２のブレード５２bはベッドＢ２の方向に給気ＳＡが到達するように調整ツマミ５３aで調整し、右下の区画Ｃ３のブレード５２cはベッドＢ３の方向に給気ＳＡが到達するように調整ツマミ５３ｃで調整し、右下の区画Ｃ４のブレード５２dはベッドＢ４の方向に給気ＳＡが到達するように調整ツマミ５３ｄで調整する。
したがって、４床(Ｂ１，Ｂ２，Ｂ３，Ｂ４)の内の各床分の吹出方向を調整ツマミ５３により任意に調整できる。勿論、手動の調整ツマミ５３に代え、ステップもモーター等を用いて、リモコンで患者自ら寝ながら操作するようにしても良い。 [blade]
As shown in FIG. 4 (FIG. 3), the blowout unit 5 is provided with a blower outlet 122 at the indoor ceiling position at the downstream end of the guide path 51 (FIG. 2), and immediately downstream of the guide path 51. Is provided with a blade 52 for adjusting the blowing air direction.
An adjustment knob 53 is provided on the side frame 13 so that the air flow guide direction of the blade 52 can be adjusted independently by the four blowing sections (C1, C2, C3, C4). That is, in FIG. 4, the blade 52a in the upper left blowing section C1 of the drawing is adjusted by the adjustment knob 53b so that the air supply SA reaches the direction of the bed B1, and similarly, the blade 52b in the upper right section C2 is adjusted to the bed B1. The adjustment knob 53a is used to adjust the supply air SA in the direction B2, and the blade 52c in the lower right section C3 is adjusted using the adjustment knob 53c so that the supply air SA reaches the bed B3. The blade 52d of the section C4 is adjusted by the adjustment knob 53d so that the supply air SA reaches the direction of the bed B4.
Therefore, the blowing direction of each floor of the four floors (B1, B2, B3, B4) can be arbitrarily adjusted by the adjusting knob 53. Of course, instead of the manual adjustment knob 53, the step may be operated using a motor or the like while the patient is sleeping on the remote controller.

[ベーン５５]
ガイド通路５１の上流には開口幅に対応して横に長いベーン５５が設けられているが、このベーン５５は空調空気の空気量および吹出風速を調整でき、図６に示すように、このベーン５５の空気流に沿う断面形状は多少湾曲した湾曲部５５１を有し、一端には回動軸５５２を設け、この回動軸５５２を中心にアクチュエータ５６によって回動し、この回動によりベーン先端部５５３とガイド経路５１のガイド内壁５１１との間隔をアクチュエータ５６によって調整できる構造になっている。
ベーン先端部５５３とガイド内壁５１１との間隔が空気通路となるが、この間隔の開度が、本実施例では、図６に示すように、全開位置Ａ１、半開位置Ａ２、１／４開位置Ａ３の３つの位置にアクチュエータ５６で３段階に制御されるようにしている。なお、別の実施例として、例えば、前記開度は風量の強弱の２段階だけ、全開位置Ａ１と半開位置Ａ２の２つの位置の２段階に制御するようにしてもよい。また、この開度が小さくなるにつれ吹出風速は早くなる。
重要なことは、どの位置でも給気ＳＡが大部分がブレード５２に送られる形状、位置に設定しておくことである。
したがって、図６ではベーン５５の全開位置Ａ１でも、ベーン先端部５５３はガイド通路５１のほぼ中間位置であるが、これ以上ベーン先端部５５３がガイド内壁５１１から離れると、誘引空気口５８から給気ＳＡが吹き出す危険性があるので、全開位置Ａ１が限界であり、ガイド内壁５１１から離れた空間は、室内空気滞留室５９(図６参照)にして室内空気を待機させる空間にしておけば良い。 [Vane 55]
An elongated vane 55 is provided upstream of the guide passage 51 in correspondence with the opening width. The vane 55 can adjust the air amount and the blown air speed of the conditioned air. As shown in FIG. The cross-sectional shape along the air flow of 55 has a curved portion 551 that is slightly curved, and is provided with a rotating shaft 552 at one end, and is rotated by an actuator 56 around the rotating shaft 552. The distance between the portion 553 and the guide inner wall 511 of the guide path 51 can be adjusted by the actuator 56.
The interval between the vane tip 553 and the guide inner wall 511 is an air passage. In this embodiment, the opening of this interval is, as shown in FIG. 6, fully open position A1, half open position A2, 1/4 open position. The actuator 56 controls the three positions A3 in three stages. As another example, for example, the opening degree may be controlled in two stages of two positions, the fully open position A1 and the half-open position A2, only in two stages of the air volume. Further, as the opening becomes smaller, the blown wind speed becomes faster.
What is important is that the air supply SA is set to a shape and position where most of the supply air SA is sent to the blade 52 at any position.
Therefore, in FIG. 6, even at the fully open position A1 of the vane 55, the vane tip 553 is almost in the middle of the guide passage 51, but when the vane tip 553 is further away from the guide inner wall 511, air is supplied from the induction air port 58. Since there is a risk that SA is blown out, the fully open position A1 is the limit, and the space away from the guide inner wall 511 may be a space in which the indoor air is waited as the indoor air retention chamber 59 (see FIG. 6).

[誘引空気口５８]
ところで、空気調和機から４方向に空気を給気し、各床への方向の風量を制御しても、単に風量が少ない場合は、図８に示すように、空気調和された吹出空気は途中の室内空気に阻害されて失速し、所定の床位置まで空調空気が十分到達しないことがある。
また、一般に天井型空気調和機であるファンコイルユニットは、冷房時に風量が少ないと吹出箇所が局部的に低温となりすぎ、その病室患者等に不快感を与えたり、結露を発生する可能性がある。
そこで、本発明の実施例では、ガイド通路５１の空気流の経路上から外れた位置に誘引空気口５８が設けられている。
この誘引空気口５８は室内の誘引空気raを誘引するために設けたもので、図６、図４に示されるように、誘引空気口５８は天井パネル１２に床に向かって開口し、かつ、この開口は誘引空気口５８はガイド通路５１の空気流の経路上から外れた位置に設け、誘引空気口５８とガイド通路５１との間には室内空気滞留室５９を設けたものである。そして、ベーン先端部５５３とガイド内壁５１１との間隔からの吹出口１２２に向かう風速のある空気ＳＡ（１次空気）が、誘引空気口５８及び室内空気滞留室５９の室内の誘引空気raを誘引して取り込み風量を増して吹出口１２２から吹き出される。 [Attraction air port 58]
By the way, even if air is supplied from the air conditioner in four directions and the air volume in the direction toward each floor is controlled, if the air volume is simply small, as shown in FIG. In some cases, the air is hampered by the room air and the air-conditioning air does not reach the predetermined floor position sufficiently.
In general, a fan coil unit that is a ceiling type air conditioner has a possibility that the blowout part becomes too cold locally when the air volume is low at the time of cooling, which may cause discomfort to the patient in the patient room or cause condensation. .
Therefore, in the embodiment of the present invention, the attraction air port 58 is provided at a position deviated from the air flow path of the guide passage 51.
This attraction air port 58 is provided for attracting indoor attraction air ra, and as shown in FIGS. 6 and 4, the attraction air port 58 opens to the ceiling panel 12 toward the floor, and In this opening, the induction air port 58 is provided at a position away from the air flow path of the guide passage 51, and an indoor air retention chamber 59 is provided between the induction air port 58 and the guide passage 51. Then, air SA (primary air) having a wind speed toward the air outlet 122 from the interval between the vane tip 553 and the guide inner wall 511 attracts the air attraction of the air at the air inlet 58 and the indoor air retention chamber 59. Then, the intake air volume is increased and the air is blown out from the air outlet 122.

[作用]
図６のような位置関係でのベーン５５の開度と誘引比を実測したのが次の表１である。
[表１]
誘引比(％)＝誘引空気量／１次空気×１００
ベーン開度：１／４開(Ａ３)・・・３２％
ベーン開度：半開(Ａ２) ・・・１０％
ベーン開度：全開(Ａ１) ・・・ ８％

すなわち、各吹出区画(Ｃ１，Ｃ２，Ｃ３，Ｃ４)で、個別に独立してベーン５５の開度を全開(強)(図６；Ａ１)、半開度(Ａ２)、１/４開(Ａ３)に操作でき、個別に風量調整可能であり、その際各ベーン開度でも[表１]のように室内空気を誘引するので、誘引空気が無い場合に比べて送風量が多くなり、特に、温調のためベーン開度を小さくして弱運転時でも、吹出風量が大きく減ることがなく、従来の４床用空気調和機に比べて、図１に示すように、各床に空調空気が到達する距離が延びる。 [Action]
Table 1 below shows the actual opening and attraction ratio of the vane 55 in the positional relationship as shown in FIG.
[Table 1]
Attraction ratio (%) = Attraction air volume / Primary air × 100
Vane opening: 1/4 open (A3) ... 32%
Vane opening: half open (A2) ... 10%
Vane opening: fully open (A1) 8%

That is, in each blowing section (C1, C2, C3, C4), the opening degree of the vane 55 is fully opened (strong) (FIG. 6; A1), half opening degree (A2), 1/4 opening (A3) independently. ), And the air volume can be adjusted individually. At that time, each vane opening also induces indoor air as shown in [Table 1]. As the temperature is controlled, the vane opening is reduced and the air flow is not greatly reduced even during weak operation. Compared to the conventional four-bed air conditioner, conditioned air is present on each floor as shown in FIG. The distance to reach is extended.

ここで、本実施例の吹出気流の状態を図７のグラフに沿って説明する。
病室Ｂを天井までの高さ２.５ｍとし、その天井中央部に本実施例の４床用空気調和機１を取り付け、図１の４つのベッド(B1,B2,B3,B4)のうち１つのベッドＢ１を例として、ベーン５５を１／４開(Ａ３)３２％とし、吹出口１２２から８０cm離れた位置に天井から５０cmまでがメッシュのカーテンを引いた場合の吹出中心気流のシュミレーションを行った。
図７に示すように、誘引空気がない場合は、吹出中心気流Ｘ２は下側の曲線のように直ぐに下降する軌跡になり、カーテンに衝突しベッドＢ１には届かない。
一方、ベーン５５を１／４開(Ａ３)した時の気流は、誘引比３２％の室内の誘引気流raを誘引することで、吹出風量が増加し、室内空気の混合で吹出温度が上昇したことで、吹出中心気流Ｘ１は上側の曲線のような軌跡になり、カーテン上部のメッシュ部分を通過し、ベッドＢ１に空調空気が到達する。 Here, the state of the blowing airflow of a present Example is demonstrated along the graph of FIG.
Hospital room B has a height of 2.5 m to the ceiling, and the four-bed air conditioner 1 of this embodiment is attached to the center of the ceiling, and one of the four beds (B1, B2, B3, B4) in FIG. Taking one bed B1 as an example, simulation was performed for the airflow from the center when the vane 55 was 1/4 open (A3) 32% and a mesh curtain was drawn up to 50 cm from the ceiling at a position 80 cm away from the outlet 122. It was.
As shown in FIG. 7, when there is no attraction air, the blowout central airflow X2 has a trajectory that descends immediately like a lower curve, collides with the curtain, and does not reach the bed B1.
On the other hand, the air flow when the vane 55 is opened 1/4 (A3) attracts the indoor induced air flow ra with an induction ratio of 32%, thereby increasing the amount of blown air and increasing the blown temperature by mixing the indoor air. Thus, the blowout central airflow X1 has a trajectory like the upper curve, passes through the mesh portion above the curtain, and the conditioned air reaches the bed B1.

本実施例は上記のような構成であるから、従来ようにダンパユニットやダクトを用いることなしに、一つの病室Ｂ内の天井中央に４床用空気調和機１を据え付けるだけで、この４床用空気調和機１によって、各床への空調空気の風量が少くなった場合でも、風量調整ベーン開度が小さいほど、吹出風速は大きくなることと相俟って、誘引空気を多く吸い込むようになり、吹出口からの吹出空気の量を多くして、十分な空調空気が各床まで到達し、各床への個別空調制御がより的確に行うことができる。また、従来のファンコイルユニットは、冷房時に風量が少ないと吹出箇所が局部的に低温となりすぎ、その病室患者等に不快感を与えたり、結露を発生する可能性があるが、誘引気流との混合により吹出温度は高くなり、低温気流による不快感を防止でき、結露も生じない４床用空気調和機とすることができる。
更に、広い一つの病室Ｂ内の領域ごとに、各ベッドの領域毎に独立して調和空気の個別制御が可能であり、しかも、１つの４床用空気調和機１だけであるので、病室Ｂ全体の温度制御が容易であり、送風機３１の一定回転をより長時間維持できるので安定した空調運転となり、装置自体の簡単で据え付けで、簡単な工事で保守も容易、且つより的確に独立して個別空調制御が可能な４床用空気調和機１とすることができる。 Since the present embodiment is configured as described above, the four-bed air conditioner 1 is simply installed in the center of the ceiling in one hospital room B without using a damper unit or duct as in the prior art. Even if the air volume of the conditioned air to each floor is reduced by the air conditioner 1, the air flow adjustment vane opening increases the blowing air speed as the air volume adjusting vane opening decreases, so that a large amount of air is drawn in. Thus, the amount of air blown from the outlet is increased so that sufficient conditioned air reaches each floor, and individual air conditioning control to each floor can be performed more accurately. In addition, the conventional fan coil unit, when the air volume during cooling is low, the blowout part becomes too cold locally, which may cause discomfort to the patient in the hospital room or the like, and may cause condensation. By mixing, the blowing temperature becomes high, an unpleasant feeling due to a low temperature airflow can be prevented, and a four-bed air conditioner that does not cause condensation can be obtained.
Furthermore, individual control of the conditioned air can be performed independently for each area of each large bed in the room B, and only one four-bed air conditioner 1 is provided. The overall temperature control is easy, the constant rotation of the blower 31 can be maintained for a longer time, so the air conditioning operation is stable, the device itself is easy to install, easy to maintain with simple construction, and more accurately and independently It can be set as the 4-bed air conditioner 1 in which individual air-conditioning control is possible.

なお、本発明の特徴を損うものでなければ、上記の実施例に限定されるものでないことは勿論である。例えば、病室を４ベッドとしたが、これ以外の複数のベット数に対応して複数個別吹出口として、これに対応したブレードとベーンを用いても良いことは勿論であり、病院以外でも複数領域を独立して空調管理する事務所等に用いても良いことも勿論である。   Needless to say, the present invention is not limited to the above-described embodiments as long as the features of the present invention are not impaired. For example, although the hospital room has 4 beds, it is of course possible to use blades and vanes corresponding to this as a plurality of individual outlets corresponding to a number of other bets, and it is also possible to use a plurality of areas other than hospitals. Of course, it may be used in an office or the like that independently manages air conditioning.
