Description

本発明は、室内の温度分布のばらつきを少なくする室内空気の温度拡散システムに関する。 The present invention relates to an indoor air temperature diffusion system that reduces variations in indoor temperature distribution.

従来の、天吊カセットタイプのエアコンは、特にビルマルチエアコンにおいては、１区画または１室の中央天井には１箇所又は数カ所の空調空気を吹き出す吹出口を設けて空調を行っていた。
このため、該吹出口から離れた箇所では、中央部とは温度差が大きくなるという問題点があり、この問題を解消するため、特許文献１に開示されているような、空調機の天井吹き出し口に気流を拡散する拡散扇を設けた装置が提案されている。
また、温度拡散装置の見栄えを良くするように、空調機の天井吹出口の内部に風受体を設け、複数のフィンを設けて吹き出し風を拡散するようにした装置も特許文献２として提案されている。 Conventional ceiling-mounted cassette type air conditioners, especially building multi-air conditioners, perform air conditioning by providing one or several outlets in the central ceiling of one section or one room to blow out conditioned air.
For this reason, there is a problem that the temperature difference between the central part and the central part becomes large in the area away from the air outlet. A device has been proposed that includes a diffuser fan that diffuses airflow into the mouth.
Furthermore, in order to improve the appearance of the temperature diffusion device, a device was proposed as Patent Document 2 in which a wind receiver is provided inside the ceiling outlet of an air conditioner, and a plurality of fins are provided to diffuse the blown air. ing.

上述した特許文献１の空調機の室内空気の温度拡散装置は、空調機自体の吹出口の下に設けるため構造は簡単であるが、見栄えが悪く、空調機の吹出口に付属することから、室内の中央部から離れた隅部等では中央部と温度差が解消されないといった問題点があった。
また、特許文献２の空調機の室内空気の温度拡散装置は、空調機の吹出口内に設けるため見栄えは良いが、構造が複雑になるといった問題点と、特許文献１と同様に空調機の吹出口に付属することから、室内の中央部から離れた隅部等では中央部と温度差が解消されないといった問題点があった。
本発明は、上記の問題点に鑑みてなされたもので、空調機の吹出口から離れた場所でも中央部と温度差が解消可能であり、かつ、見栄えのよい温度拡散システムを提供しようとするものである。 The temperature diffusion device for indoor air in the air conditioner of Patent Document 1 described above has a simple structure because it is installed under the air outlet of the air conditioner itself, but it is unsightly and is attached to the air outlet of the air conditioner. There was a problem in that the temperature difference between the center and the corner of the room far away from the center could not be resolved.
In addition, although the indoor air temperature diffusion device of the air conditioner of Patent Document 2 looks good because it is installed inside the air conditioner's outlet, it has the problem of a complicated structure and, as in Patent Document 1, the temperature diffusion device of the air conditioner Since it is attached to the air outlet, there is a problem that the temperature difference between the center and the corner of the room, which is far away from the center of the room, cannot be eliminated.
The present invention has been made in view of the above-mentioned problems, and aims to provide a temperature diffusion system that can eliminate the temperature difference from the central part even in a place far from the air outlet of an air conditioner and has a good appearance. It is something.

上記課題を解決するために、本発明は、天井の適所に空気調和された冷房或いは暖房の空気を吹き出す吹出口が設けられ、該吹出口から離れた天井近傍や床近傍の空気の温度分布のばらつきが大きな箇所に設ける室内空気の温度拡散装置であって、
該室内空気の温度拡散装置は、天井裏に上部を密封する枠体を設け、該枠体内は中央空間部とそれを囲む外側空間部とは隔壁を隔てて設けられ、該中央空間部と外側空間部とは枠体の上部空間部で連通し、該中央空間部には送風方向が正逆に切り替えられる軸流ファンの送風機構を設けるとともに、中央空間部の下部には天井側に開口する中央開口を設けるとともに、該枠体の外側空間部の下部にも天井に沿って外側に向かう外側開口を設け、天井面にファンが露出することがないようにし、
したがって、冬場には前記外側に向かう外側開口から室内の暖められた空気を吸い込み、前記送風機構によって前記中央開口から暖められた空気を室内の真下に吹き出し、夏場には前記中央開口から室内の冷やされた空気を吸い込み、前記送風機構によって前記外側開口から前記冷やされた空気を天井に沿って吹き出す室内空気の温度拡散システムである。
また、前記送風機構のファンの１つの実施態様は、送風方向が外部信号を切り替えることによって、送風方向を正逆に切り替えることができるリバーシブルファンである室内空気の温度拡散システムである。或いは、前記送風機構の１つの実施態様は、ファン全体を反転させることによって、送風方向を正逆に切り替えられる室内空気の拡散システムである。
上記の送風機構のファンは複数にした室内空気の温度拡散システムでもよく、上述した実施態様は、ビルマルチエアコンに用いた室内空気の温度拡散システムでもよい。 In order to solve the above problems, the present invention provides an outlet for blowing out air-conditioned cooling or heating air at an appropriate location on the ceiling, and changes the temperature distribution of the air near the ceiling or near the floor away from the outlet. An indoor air temperature diffusion device installed in a location with large variations,
The room air temperature diffusion device is provided with a frame body that seals the upper part in the ceiling, and inside the frame body, a central space part and an outside space part surrounding it are separated by a partition wall, and the central space part and the outside part are separated from each other by a partition wall. The upper space of the frame communicates with the space, and the central space is equipped with an axial fan blowing mechanism that can switch the air blowing direction between forward and reverse directions, and the lower part of the center space is opened toward the ceiling. In addition to providing a central opening, an outer opening extending outward along the ceiling is also provided at the lower part of the outer space of the frame so that the fan is not exposed to the ceiling surface,
Therefore, in the winter, warm air in the room is sucked in through the outer opening facing outside, and the warm air is blown out from the central opening directly below the room by the blower mechanism, and in the summer, the indoor air is cooled from the central opening. This indoor air temperature diffusion system sucks in the cooled air and blows out the cooled air from the outside opening along the ceiling using the blower mechanism.
Further, one embodiment of the fan of the ventilation mechanism is an indoor air temperature diffusion system in which the fan is a reversible fan that can switch the ventilation direction between forward and reverse directions by switching an external signal. Alternatively, one embodiment of the ventilation mechanism is an indoor air diffusion system in which the direction of ventilation can be switched between forward and reverse by reversing the entire fan.
The fan of the above-mentioned ventilation mechanism may be a plurality of indoor air temperature diffusion systems, and the embodiment described above may be an indoor air temperature diffusion system used in a building multi-air conditioner.

本発明の室内空気の温度拡散システムによれば、天井の適所に空気調和された冷房或いは暖房の空気を吹き出す吹出口が設けられ、該吹出口から離れた天井の空気の温度分布のばらつきが大きな箇所に設ける室内空気の温度拡散装置を設けたシステムとしたので、室内空気が攪拌され、特に、冬場には暖かい空気が天井近傍に滞留する傾向があるので、この室内天井近傍の暖められた空気を強制的に温度拡散装置の送風機構によって、中央開口から暖められた空気を室内の真下に吹き出し、空気の温度分布の均一化を図っており、逆に、夏場には冷えた空気が床近傍に滞留する傾向があるので、これを強制的に温度拡散装置で吸い込み、天井面に沿った方向に（或いは、“天井面に対し水平方向に”）吐き出して室内の空気の温度分布の均一化を図っている。
また、室内温度の拡散作用は、送風機の送風方向を冬場と夏場では逆転させる必要があるが、少なくとも１つのファン全体を反転させてればよい。或いは、反転させなくともリバーシブルファンを用いれば、送風方向が外部信号を切り替えることによって、送風方向を簡単に変えることができる。
また、熱交換器を用いる必要がなく、ファンだけを組み込むだけで小型にできるので、天井裏に設置することができ、天井にファンが露出することがないので天井面の見栄えがよい。
さらに、本発明の温度拡散システムにおける温度拡散作用は、室内毎に設定可能であるので、本温度拡散システムは中央空調施設から部屋ごとに空調空気を送風し、部屋毎に空調運転の調節を行うビルマルチエアコンに最適である。 According to the indoor air temperature diffusion system of the present invention, an outlet for blowing out air-conditioned cooling or heating air is provided at an appropriate location on the ceiling, and the temperature distribution of the ceiling air away from the outlet has large variations. Since the system is equipped with indoor air temperature diffusion devices installed at various locations, the indoor air is agitated, and especially in winter, warm air tends to stay near the ceiling. The air blowing mechanism of the temperature diffusion device forces the heated air to blow out from the central opening directly below the room, making the temperature distribution of the air uniform. Conversely, in the summer, the cooled air flows near the floor. This air tends to stay in the room, so it is forcibly sucked in by a temperature diffusion device and discharged in a direction along the ceiling surface (or "horizontal to the ceiling surface") to equalize the temperature distribution of the indoor air. We are trying to
Further, in order to diffuse the indoor temperature, it is necessary to reverse the blowing direction of the fan in winter and summer, but it is sufficient to reverse the direction of at least one fan in its entirety. Alternatively, if a reversible fan is used, the direction of air blowing can be easily changed by switching an external signal without reversing the fan.
In addition, since there is no need to use a heat exchanger and the size can be reduced by just incorporating a fan, it can be installed in the ceiling, and the ceiling surface looks good because the fan is not exposed on the ceiling.
Furthermore, since the temperature diffusion effect in the temperature diffusion system of the present invention can be set for each room, the temperature diffusion system blows conditioned air from the central air conditioning facility to each room and adjusts the air conditioning operation for each room. Ideal for building multi-air conditioners.

本発明の温度拡散システムの実施例１から４について図面を参照して説明する。 Examples 1 to 4 of the temperature diffusion system of the present invention will be described with reference to the drawings.

［実施例１］
まず、本発明の温度拡散システムの好適な実施例１について説明するが、図１は本発明の全体の概略を説明する作用説明図である。
図１の本温度拡散システムにおいて、右半分は本温度拡散システムを冬場で稼働させた冬モードの説明図、左半分は本温度拡散システムを夏場で稼働させた夏モードの説明図である。
先ず、室内の天井のほぼ中央部には、天吊カセットタイプエアコン（室内機）１があり、本実施例１では中央空調施設(図示せず。)から各部屋に空調空気を送風し、部屋(室内)Ｒ毎に空調の調節を行うもので、本温度拡散システムはこのようなビルマルチエアコンに最適である。

First, a preferred embodiment 1 of the temperature diffusion system of the present invention will be described. FIG. 1 is an operational explanatory diagram illustrating the overall outline of the present invention.
In the present temperature diffusion system of FIG. 1, the right half is an explanatory diagram of the winter mode in which the present temperature diffusion system is operated in the winter, and the left half is an explanatory diagram of the summer mode in which the present temperature diffusion system is operated in the summer.
First, there is a ceiling-suspended cassette type air conditioner (indoor unit) 1 almost in the center of the ceiling in the room, and in the first embodiment, conditioned air is blown from the central air conditioning facility (not shown) to each room, This temperature diffusion system is ideal for such building multi-air conditioners, as the air conditioning is adjusted for each room (R).
In FIG. 1, an outlet 11 for blowing out air-conditioned cooling or heating air and an inlet 12 for returning air are provided at appropriate locations on the ceiling, and there is a large variation in the temperature distribution of the air on the ceiling away from the outlet 11. A desired number of indoor air temperature diffusion devices 2 are installed near the wall or in the corner R1 of R. This temperature diffusion device 2 includes a blower fan, but does not include a heat exchanger (coil). Indoor air is stirred by this temperature diffusion device 2.

図１の右半分の冬モードについて説明すると、冬場には暖かい空気が天井近傍に滞留（符号Ｗ部分）する傾向があるので、この室内天井近傍の暖められた空気Ｗを外側開口２３１（吸込口）(図２を参照)から送風機構２５により吸い込み、温度拡散装置２の底面中心部に設けた風速が速い中央開口２２１(吹出口)から暖かい空気を、送風機構２５によって真下に吹き出し、部屋(居室)Ｒの温度分布の均一化を図っている。
また、図１の左半分の夏モードについて説明すると、逆に、夏場には冷えた空気が床近傍に滞留（符号Ｓ部分）する傾向があるので、これを強制的に温度拡散装置２の底面中心部に設けた風速が速い中央開口２２１(吸込口)から、風向きを冬モードから反転させた送風機構２５により真上に吸い込み、これを外側開口２３１（吸込口）から天井に沿うように側方に吐き出して部屋（居室）Ｒの温度分布の均一化を図っている。 To explain the winter mode in the right half of Fig. 1, warm air tends to stay near the ceiling in the winter (portion marked W). ) (see Fig. 2), warm air is sucked in by the blower mechanism 25 from the central opening 221 (air outlet) with a high wind speed provided at the center of the bottom of the temperature diffusion device 2, and is blown out directly below by the blower mechanism 25. Efforts are being made to equalize the temperature distribution in living room R.
Also, to explain the summer mode shown in the left half of FIG. From the central opening 221 (suction port) with high wind speed provided in the center, the air blowing mechanism 25 whose direction is reversed from the winter mode sucks the air directly upwards, and from the outside opening 231 (suction port) it blows the air to the side along the ceiling. The temperature distribution in the room (living room) R is made uniform by discharging the air in the opposite direction.

〈実施例１の温度拡散装置２〉
ここで、実施例１で使用する温度拡散装置２について、図２に添って詳しく説明する。
図２(ａ)は、図１に示す温度拡散装置２の実施例１の断面図、図２(ｂ)はその底面図であるが、室内空気の温度拡散装置２は、天井裏に上部を密封する枠体２１を設け、枠体２１の内部には円筒状或いは矩形状の中央空間部２２と枠体２１の内部で中央空間部２２を囲むように環状の外側空間部２３とが隔壁２４で隔てられている。
枠体２１内の筒状の中央空間部２２と環状の外側空間部２２とは、枠体２１の上部の天板板２１２によって形成される天井の上部空間部２１２で連通し、枠体２１の中央空間部２２の下部底面には天井下側に開口する中央開口２２１が形成され、この中央開口部２２１には一部に空気の通過を阻止する塞ぎ板２２１１を配したパンチング板２２１２が設けられ、枠体２１の環状の外側空間部２３には天井に沿って、空気がブレード等で外側に向かうように、或いは、天井付近から空気を吸い込むように環状の外側開口２３１が設けられている。
該外側に向かう空気の流れを形成するために、図２(ｂ)に示すように、外側開口２３１の内側には断面台形の中コーン２３２とそれに略平行した外側に外コーン２３３が設けられ、この両コーンは接続金具２３４によって支持されている。
したがって、例えば、冬モードにおいては、外側開口２３１から天井付近の空気を吸い込み、外側空間部から上部空間を通過し、中央空間部に導入され、中央開口２２１から吹き出される空気の流れを形成することができ、夏モードにおいては、その逆の空気の流れを形成することができる。
この空気の正逆の流れを強制的に形成するために、中央空間部２２には送風方向が正逆に切り替えられる送風機構２５ａが設けられているが、実施例１の送風機構２５a（２５）のファン（送風機)は、外部信号を切り替えることによって、送風方向を変えるリバーシブルファン２５１を用いており、これは、例えば、従来よりよく知られているPWM信号の入力信号パルスのデューティ比を変えて簡単に送風方向が変えられるリバーシブルファン２５１を使用している。なお、送風方向が簡単に変える機構であれば、他の直流モーターの正負極を反転させるリバーシブルファン等を使用してもよい。 <Temperature diffusion device 2 of Example 1>
Here, the temperature diffusion device 2 used in Example 1 will be described in detail with reference to FIG. 2.
FIG. 2(a) is a sectional view of the first embodiment of the temperature diffusion device 2 shown in FIG. 1, and FIG. 2(b) is a bottom view thereof. A sealing frame 21 is provided, and inside the frame 21 there is a cylindrical or rectangular central space 22 and an annular outer space 23 surrounding the central space 22 inside the frame 21, and a partition wall 24. separated by
The cylindrical central space 22 and the annular outer space 22 in the frame 21 communicate with each other through an upper space 212 of the ceiling formed by the top plate 212 at the top of the frame 21 . A central opening 221 that opens toward the lower side of the ceiling is formed in the lower bottom surface of the central space 22, and a punching plate 2212 is provided in a part of this central opening 221 with a closing plate 2211 that prevents air from passing through. An annular outer opening 231 is provided in the annular outer space 23 of the frame body 21 along the ceiling so that air is directed outward with a blade or the like or air is sucked in from near the ceiling.
In order to form the air flow toward the outside, as shown in FIG. 2(b), an inner cone 232 with a trapezoidal cross section is provided inside the outer opening 231, and an outer cone 233 is provided on the outer side substantially parallel to the inner cone 232. Both cones are supported by connecting fittings 234.
Therefore, for example, in the winter mode, air near the ceiling is sucked in through the outer opening 231, passes through the upper space from the outer space, is introduced into the central space, and forms a flow of air that is blown out from the central opening 221. In summer mode, the opposite air flow can be created.
In order to forcibly form this forward and reverse flow of air, a blowing mechanism 25a that can switch the blowing direction between forward and reverse is provided in the central space 22, but the blowing mechanism 25a (25) of the first embodiment The fan (air blower) uses a reversible fan 251 that changes the air blowing direction by switching an external signal. A reversible fan 251 is used that allows the air blowing direction to be easily changed. Note that a reversible fan or the like that reverses the positive and negative poles of another DC motor may be used as long as the mechanism allows the blowing direction to be easily changed.

したがって、図１に示す冬モード(図右半分)では、中央空間部２２に設けたリバーシブルファン２５１が下向きの送風が可能であり、冬場には暖かい空気が天井近傍に滞留（符号Ｗ部分）する傾向があるので、この室内天井近傍の暖められた空気Ｗを外側開口２３１（吸込口）(図２を参照)からリバーシブルファン２５１により吸い込み、中央開口２２１(吹出口)から暖かい空気をリバーシブルファン２５１によって真下に吹き出し、部屋（居室Ｒ）の温度分布の均一化を図っている。
逆に、図１に示す夏モード(図左半分)では、リバーシブルファンで２５１によって、送風方向は反対の上向きの冷気吸い込み送風が可能であり、夏場には冷えた空気が床近傍に滞留（符号Ｓ部分）する傾向があるので、これを強制的に温度拡散装置２の中央開口２２１(吸込口)から真上に吸い込み、これを外側開口２３１（吸込口）から天井に沿うように吐き出して室内の空気の温度分布の均一化を図っている。
なお、送風については、環状の外側開口２２３１の開口面積が、中央開口２２１の開口面積より小さいので、中心開口２２１での風速の方が速いので、左右方向よりも上下方向の風速を速くすることが可能である。
このように、室内空気の温度拡散システムによれば、冬場と夏場で送風通路を切り替えて天井近傍や床近傍の空気を攪拌し効率よく室内の空気の温度分布の均一化が可能となる。 Therefore, in the winter mode shown in FIG. 1 (right half of the figure), the reversible fan 251 provided in the central space 22 can blow air downward, and in winter, warm air stays near the ceiling (portion marked W). Therefore, the warm air W near the indoor ceiling is sucked in by the reversible fan 251 from the outer opening 231 (intake port) (see FIG. 2), and the warm air is sucked in by the reversible fan 251 from the central opening 221 (air outlet). The air is blown directly downwards to ensure a uniform temperature distribution in the room (room R).
On the other hand, in the summer mode shown in Figure 1 (left half of the diagram), the reversible fan 251 can suck in and blow cool air in the opposite upward direction. S part), so this is forcibly sucked directly upward from the central opening 221 (suction port) of the temperature diffusion device 2, and then discharged from the outside opening 231 (suction port) along the ceiling and into the room. This aims to equalize the temperature distribution of the air.
Regarding air blowing, since the opening area of the annular outer opening 2231 is smaller than the opening area of the central opening 221, the wind speed at the central opening 221 is faster, so the wind speed in the vertical direction should be faster than in the horizontal direction. is possible.
In this way, according to the indoor air temperature diffusion system, it is possible to efficiently equalize the temperature distribution of the indoor air by switching the ventilation passages between winter and summer to stir the air near the ceiling and near the floor.

［実施例２］
次に、実施例２について図３を参照して説明するが、実施例２が前述した実施例１と異なる構成は、送風機構２５がリバーシブルファンではなく、通常のファンの軸方向の一方向に送風することができるファン、例えば軸流ファン２５２であり、この軸流ファン２５２自体を１８０°反転させる反転操作部２５３を設けて、この反転操作部２５３によって軸流ファン２５２を１８０°反転させることによって送風方向が正逆に切り替えられる送風機構２５ｂを用いていることである。他の構成は実施例１と同じであるので説明は省略する。
実施例２では、一般的な軸流ファン２５２を用いているので、風量に応じた規格のファンの入手が容易である。なお、軸流ファン２５２でなくとも軸方向の一方向に送風することができるファンであればよい。 [Example 2]
Next, a second embodiment will be described with reference to FIG. 3. The difference between the second embodiment and the first embodiment described above is that the blower mechanism 25 is not a reversible fan, but is oriented in one direction in the axial direction of a normal fan. A fan capable of blowing air, for example, an axial fan 252, is provided with a reversing operation section 253 that inverts the axial fan 252 itself by 180 degrees, and the reversing operation section 253 rotates the axial fan 252 by 180 degrees. The purpose is to use a blowing mechanism 25b whose blowing direction can be switched between forward and reverse directions. The other configurations are the same as in the first embodiment, so their explanation will be omitted.
In the second embodiment, since a general axial flow fan 252 is used, it is easy to obtain a fan with a specification corresponding to the air volume. Note that the fan 252 does not need to be the axial fan 252 and may be any fan that can blow air in one direction in the axial direction.

［実施例３］
次に、実施例３について図４を参照して説明するが、実施例２が前述した実施例１と異なる構成は、実施例１では送風機構２５ａ(２２)に設置したリバーシブルファン２５１が１個であるが、実施例３の送風機構２５ｃではリバーシブルファン２５１を複数の４個とした点である。こうすることで、送風機構２５ｃの総風量を大きくすることができる。なお、実施例３では送風機構２５ｃのリバーシブルファン２５１を複数としているが、必要に応じて４個でなくとも２個でも３個でもよく、各送風機構２５のファンを実施例２のような軸流ファン２５２と反転操作部２５３との組み合わせた構成にしてもよい。 [Example 3]
Next, Embodiment 3 will be described with reference to FIG. 4. The difference between Embodiment 2 and Embodiment 1 described above is that in Embodiment 1, only one reversible fan 251 is installed in the ventilation mechanism 25a (22). However, the ventilation mechanism 25c of the third embodiment has a plurality of four reversible fans 251. By doing so, the total air volume of the air blowing mechanism 25c can be increased. In the third embodiment, the blower mechanism 25c has a plurality of reversible fans 251, but if necessary, there may be two or three reversible fans instead of four, and the fans of each blower mechanism 25 can be arranged on a shaft like in the second embodiment. A configuration in which the flow fan 252 and the reversing operation section 253 are combined may be used.

本発明の実施例の室内空気の温度拡散システムによれば、居室Ｒの天井Ｃの適所に空気調和された冷房或いは暖房の空気を吹き出す吹出口１１が設けられ、吹出口１１から離れた天井Ｃの空気の温度分布のばらつきが大きな箇所である隅部Ｒ１に室内空気の温度拡散装置２を設けたので、室内Ｒ空気が攪拌され、冬場（冬モード）には暖かい空気Ｗが天井近傍に滞留する傾向があるので、この室内Ｒ天井近傍の暖められた空気Ｗを強制的に温度拡散装置２の送風機構２５によって、中央開口２２１から室内の下方に吹き出し、空気の温度分布の均一化を図っており、逆に、夏場には冷えた空気Ｓが床近傍に滞留する傾向があるので、これを温度拡散装置２で吸い込み、外側開口２３１から天井に沿うように側方に向けて吐き出して室内の空気の温度分布の均一化を図ることができる。 According to the indoor air temperature diffusion system according to the embodiment of the present invention, the air outlet 11 for blowing out air-conditioned cooling or heating air is provided at a suitable location on the ceiling C of the living room R, and the air outlet 11 that blows out air-conditioned cooling or heating air is provided at a suitable location on the ceiling C of the living room R. Since the indoor air temperature diffusion device 2 is installed in the corner R1 where there is a large variation in the temperature distribution of the air, the indoor air R is agitated and warm air W stays near the ceiling in winter (winter mode). Therefore, the warmed air W near the ceiling of the room R is forcibly blown out from the central opening 221 to the lower part of the room by the blower mechanism 25 of the temperature diffusion device 2, thereby making the temperature distribution of the air uniform. On the other hand, in the summer, cold air S tends to stay near the floor, so it is sucked in by the temperature diffusion device 2 and discharged laterally along the ceiling from the outside opening 231 to release it indoors. The temperature distribution of the air can be made uniform.

このように、本発明の室内空気の温度拡散システムの各実施例によれば、天井の適所に空気調和された冷房或いは暖房の空気を吹き出す吹出口が設けられ、該吹出口から離れた天井の空気の温度分布のばらつきが大きな箇所に設ける室内空気の温度拡散装置を設けたので、室内空気が攪拌され、特に、冬場には暖かい空気が天井近傍に滞留する傾向があるので、この室内天井近傍の暖められた空気を強制的に温度拡散装置の送風機構によって、中央開口から暖められた空気を室内の真下に吹き出し、空気の温度分布の均一化を図っており、逆に、夏場には冷えた空気が床近傍に滞留する傾向があるので、これを強制的に温度拡散装置で吸い込み、天井面に沿った方向に（或いは、“天井面に対し水平方向に”）吐き出して室内の空気の温度分布の均一化を図ることができる。
また、室内温度の拡散作用は、送風機の送風方向を冬場と夏場では逆転させる必要があるが、少なくとも１つのファン全体を反転させてればよい。或いは、反転させなくともリバーシブルファンを用いれば、送風方向が外部信号を切り替えることによって、送風方向を簡単に変えることができる。
また、温度拡散装置２は熱交換器を用いる必要がなく、ファンだけを組み込むだけで小型であるので、装置全体を天井裏に設置することができ、天井にファンが露出することがないので天井が広く見え天井面の見栄えがよい。
さらに、本発明の温度拡散システムの各実施例における温度拡散作用は、室内毎に設定可能であるので、本温度拡散システムは中央空調施設から部屋ごとに空調空気を送風し、部屋毎に空調運転の調節を行うビルマルチエアコンに最適である。
なお、本発明の特徴を損なうものでなければ、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。 As described above, according to each of the embodiments of the indoor air temperature diffusion system of the present invention, an outlet for blowing out air-conditioned cooling or heating air is provided at an appropriate location on the ceiling, and the outlet is provided at an appropriate location on the ceiling to blow out air for air conditioning or heating. Since we installed an indoor air temperature diffusion device in a place where there is a large variation in the temperature distribution of the air, the indoor air is agitated, and especially in winter, warm air tends to stay near the ceiling. The heated air is forcibly blown out from the central opening directly below the room using the blower mechanism of the temperature diffusion device, to even out the temperature distribution of the air. Since the air tends to stay near the floor, this air is forcibly sucked in by a temperature diffusion device and discharged in a direction along the ceiling (or horizontally to the ceiling) to improve indoor air flow. Uniform temperature distribution can be achieved.
Further, in order to diffuse the indoor temperature, it is necessary to reverse the blowing direction of the fan in winter and summer, but it is sufficient to reverse the direction of at least one fan in its entirety. Alternatively, if a reversible fan is used, the direction of air blowing can be easily changed by switching an external signal without reversing the fan.
In addition, the temperature diffusion device 2 does not require the use of a heat exchanger, and is small in size and only incorporates a fan, so the entire device can be installed in the ceiling, and the fan is not exposed on the ceiling. It looks spacious and the ceiling looks good.
Furthermore, since the temperature diffusion effect in each embodiment of the temperature diffusion system of the present invention can be set for each room, the present temperature diffusion system blows conditioned air from the central air conditioning facility to each room, and performs air conditioning operation for each room. It is ideal for building multi-air conditioners that adjust the air conditioner.
It goes without saying that the present invention is not limited to the above-mentioned embodiments as long as it does not impair the characteristics of the present invention.
