Description

本発明は、発熱量の多い機器が設置される天井高さの高い大空間を恒温に冷房するための大空間用空調システムに関する。   The present invention relates to an air conditioning system for a large space for cooling a large space with a high ceiling where equipment with a large amount of heat is installed to a constant temperature.

一般に、金属加工工場などの工場は、生産設備の要請により、天井高さの高い大空間となる。この種の大空間には、発熱量の多い工作機械などの機器が設置されるため、温度が一定で風速の遅い室内環境が必要とされる。したがって、従来、このよう大空間を冷房するために各種空調システムが装備されている。   In general, factories such as metal processing factories have large spaces with high ceilings due to demands for production equipment. In this kind of large space, machine tools and other devices that generate a large amount of heat are installed, so an indoor environment with a constant temperature and a low wind speed is required. Therefore, various air conditioning systems are conventionally provided to cool such a large space.

しかしながら、従来のこの種の空調システムでは、機器の廃熱により加熱された空気から熱負荷を取り除くのに時間が掛かり、長時間に亘って機器からの廃熱が空調空間を漂い、機器の性能に支障を及ぼす虞があるという問題がある。   However, in this type of conventional air conditioning system, it takes time to remove the heat load from the air heated by the waste heat of the equipment, and the waste heat from the equipment drifts through the air-conditioned space for a long time. There is a problem that there is a risk of disturbing.

また、発熱量の多い機器が設置されるエリアと該機器が設置されないエリアとの間での温度ムラや、発熱量の多い機器が稼働したり停止したりする動作を不規則に行うことによる温度ムラなどが生じ易い。さらに、前記機器からの廃熱が空調空間内を水平移動することで、吸込口に向かって川の流れのように高温域が形成され易い。したがって、これらの要因により、空調空間内を恒温に保持することが難しいという問題がある。   In addition, temperature unevenness between an area where a device with a large amount of heat generation is installed and an area where the device is not installed, or a temperature caused by irregularly performing operations that cause a device with a large amount of heat to operate or stop Unevenness is likely to occur. Further, the waste heat from the device moves horizontally in the air-conditioned space, so that a high temperature region is easily formed like a river flow toward the suction port. Therefore, there is a problem that it is difficult to keep the air-conditioned space at a constant temperature due to these factors.

そこで、上記したような問題を解決するため、従来、例えば、壁面に設置した給気チャンバの給気口から空調空間内に向かって側方に吹き出される低温空気に旋回成分を与えることによって、低温空気に誘引される空気量を増加させ、空調空間の上下温度差を減少させるようにした置換換気システムが提案されている（例えば、特許文献１、２又は非特許文献１を参照）。   Therefore, in order to solve the problems as described above, for example, by giving a swirl component to the low-temperature air blown sideways from the air supply port of the air supply chamber installed on the wall surface toward the air-conditioned space, A replacement ventilation system has been proposed in which the amount of air attracted by low-temperature air is increased and the temperature difference between the conditioned spaces is reduced (see, for example, Patent Documents 1 and 2 or Non-Patent Document 1).

また、天井に設置した送風ユニットのノズルから高速で吹き出したジェットエアの運動量を利用して見かけ上の換気回数を増やすことによって、室内の恒温環境を形成するようにしたデリベント（登録商標）式の空調換気システムも提案されている（例えば、特許文献３又は非特許文献２を参照）。   In addition, by using the momentum of jet air blown out at high speed from the nozzle of the blower unit installed on the ceiling, the apparent ventilation frequency is increased to form a constant temperature environment in the room. An air-conditioning ventilation system has also been proposed (see, for example, Patent Document 3 or Non-Patent Document 2).

しかしながら、上記した従来の置換換気システムでは、給気チャンバが壁面に設置されているため、空調空間内に設置された機器の配置によっては、給気チャンバの給気口から吹き出された低温空気が機器の周囲に十分に到達しない虞がある。そのため、空調空間内に温度差が生じてしまい、空調空間内を恒温に維持することが難しいという問題が生じている。   However, in the conventional replacement ventilation system described above, since the air supply chamber is installed on the wall surface, depending on the arrangement of the equipment installed in the air-conditioned space, low-temperature air blown out from the air supply port of the air supply chamber may be There is a risk of not reaching the surroundings of the device sufficiently. For this reason, a temperature difference occurs in the air-conditioned space, and there is a problem that it is difficult to maintain the air-conditioned space at a constant temperature.

また、壁面に設置された給気チャンバの給気口の直近では冷房用空気の風速が速いため、空調空間内での作業に支障が生じるという問題がある。   In addition, there is a problem in that work in the air-conditioned space is hindered because the air velocity of the cooling air is high in the immediate vicinity of the air supply port of the air supply chamber installed on the wall surface.

さらに、壁面を給気チャンバの設置スペースとして利用しているため、壁際に備品等を置くことができなかったり、或いは、工場の場合には給気チャンバがフォークリフトの走行の邪魔になったりするといった問題も生じている。   Furthermore, since the wall surface is used as an installation space for the air supply chamber, equipment cannot be placed near the wall, or in the case of a factory, the air supply chamber may interfere with the running of the forklift. There are also problems.

さらにまた、例えば１００ｍ四方のスペースの工場では、両側の壁に設置された給気チャンバがそれぞれ長さ５０ｍずつの温度環境を受け持たなければならないため、空調空間内の温度環境にムラが出易くなるというように、大空間になる程、繊細な温度制御を行うことができないといった問題もある。   Furthermore, in a factory with a space of 100 m square, for example, the air supply chambers installed on the walls on both sides must be responsible for a temperature environment of 50 m in length, so that the temperature environment in the air-conditioned space tends to be uneven. As described above, there is a problem that as the space becomes larger, delicate temperature control cannot be performed.

一方、上記した従来のデリベント（登録商標）式の空調換気システムでは、送風ユニットのノズルの正面では気流速度が非常に速いため、空調空間内での作業に支障が生じるという問題がある。   On the other hand, the above-mentioned conventional Derivet (registered trademark) type air-conditioning ventilation system has a problem in that work in the air-conditioned space is hindered because the air velocity is very fast in front of the nozzle of the blower unit.

また、空調空間内の機器からの発熱量が多い場合や空調空間内の天井高さが高い場合には、汎用品クラスの送風ユニットのノズルの誘引気流だけでは冷房用空気を十分に撹拌することができないため、空調空間内を所定温度に保持することが難しいといった問題もある。   In addition, when the amount of heat generated from the equipment in the air-conditioned space is large or the ceiling height in the air-conditioned space is high, the air for cooling must be sufficiently agitated only with the induced airflow from the nozzle of the general-purpose class blower unit. Therefore, there is a problem that it is difficult to maintain the air-conditioned space at a predetermined temperature.

さらに、ノズルの配置が工場の生産設備の配置に影響を受けるという問題や、ノズルの誘引気流が個別且つ分断的で混合効率が悪いといった問題もある。   Furthermore, there is a problem that the arrangement of the nozzles is affected by the arrangement of the production equipment in the factory and a problem that the induced airflow of the nozzles is individual and fragmented, resulting in poor mixing efficiency.

本発明は、上記した各種課題を解決すべくなされたものであり、空調空間内を恒温に維持することができると共に空調空間内での作業に支障を及ぼすことのない大空間用空調システムを提供することを目的とする。   The present invention has been made to solve the various problems described above, and provides an air conditioning system for large spaces that can maintain a constant temperature in the air-conditioned space and does not interfere with the work in the air-conditioned space. The purpose is to do.

An air conditioning system for large space for cooling a large space with high height, and the air for cooling is forcibly blown upward at a plurality of locations outside the air-conditioning control space, thereby rising from the air conditioning space.

以下、図面を参照しつつ、本発明の実施の形態に係る大空間用空調システムについて説明する。なお、以下の説明では、発熱体としての工作機械Ｍが複数台設置された金属加工工場の大空間Ｓに本発明に係る大空間用空調システム１０を設置した場合について例示して説明する。   Hereinafter, an air conditioning system for large spaces according to an embodiment of the present invention will be described with reference to the drawings. In the following description, a case where the large space air conditioning system 10 according to the present invention is installed in a large space S of a metal processing factory where a plurality of machine tools M as heating elements are installed will be described as an example.

大空間用空調システム１０が設置される大空間Ｓは、天井高さが高く、所定温度に維持することの必要な空調空間Ｓａと、空調空間Ｓａより上方の天井レベルに位置して所定温度に維持する必要のない空調管理外空間Ｓｂと、を備えている。   The large space S in which the large-space air conditioning system 10 is installed has a high ceiling height and is required to be maintained at a predetermined temperature and an air conditioning space Sa that needs to be maintained at a predetermined temperature and a ceiling level above the air conditioning space Sa. And an air conditioning management outside space Sb that does not need to be maintained.

本発明の実施の形態における一例として、大空間Ｓは、２０００ｍ２（４０ｍ×５０ｍ四方）の床面積と１７ｍの天井高さ（直天）を有しており、床上６ｍまでの高さの空間が空調空間Ｓａに設定されている。この空調空間Ｓａは平面的に１０区画のゾーンに分割され、各ゾーンはそれぞれ２００ｍ２の床面積を有している。 As an example in the embodiment of the present invention, the large space S has a floor area of 2000 m 2 (40 m × 50 m square) and a ceiling height (straight sky) of 17 m, and is a space up to 6 m above the floor. Is set in the conditioned space Sa. This air-conditioned space Sa is divided into 10 zones in a plan view, and each zone has a floor area of 200 m 2 .

空調空間Ｓａには、発熱量の変動する工作機械Ｍがマットスラブ（耐圧版又はベタ基礎）上に固定されて配置されている。また、空調管理外空間Ｓｂには、対向する壁間に生産用クレーンＣが直線的に移動可能なように設けられている。   In the air-conditioned space Sa, a machine tool M whose heating value varies is fixed and arranged on a mat slab (pressure plate or solid foundation). Further, the production crane C is provided in the air conditioning management outside space Sb so as to be linearly movable between the opposing walls.

空調空間Ｓａでは、年間を通じて、温度を２３℃±１℃、気流速度を０．６ｍ／ｓ以下の環境に維持することが要求されている。この環境を実現するため、本発明の実施の形態に係る大空間用空調システム１０は、冷房用空気を強制的に送出する空調機１１と、空調機１１から送出された冷房用空気を所定位置に導く給気ダクト１２と、給気ダクト１２に配設されて冷房用空気を斜め上方に向けて吹き出す複数の吹出口１３と、を備えて構成されている。   In the air-conditioned space Sa, it is required to maintain an environment with a temperature of 23 ° C. ± 1 ° C. and an air velocity of 0.6 m / s or less throughout the year. In order to realize this environment, the large space air conditioning system 10 according to the embodiment of the present invention forcibly sends out air for cooling and the air for cooling sent from the air conditioner 11 at a predetermined position. And a plurality of outlets 13 that are arranged in the air supply duct 12 and blown out the cooling air obliquely upward.

空調機１１、給気ダクト１２、及び吹出口１３はそれぞれ空調管理外空間Ｓｂに配設されている。空調機１１は、例えば、各ゾーンに１台ずつ設置され、合計で８台設置されている。また、後述するように、その他に外気処理用の空調機（外調機）が、例えば２台設置されている。各空調機１１は、空気を冷却して冷房用空気を生成する冷却コイル（図示せず）と、室内の熱負荷によって冷房用空気の給気速度が１０〜３５ｍ／ｓの間で可変となるように回転数制御されるインバータ付きの送風機（図示省略）と、を備えている。空調機１１は、冷房用空気の給気温度が所定温度（例えば、１６℃）になるようカスケード制御される。   The air conditioner 11, the air supply duct 12, and the air outlet 13 are respectively disposed in the air conditioning management outside space Sb. For example, one air conditioner 11 is installed in each zone, and a total of eight air conditioners 11 are installed. In addition, as will be described later, for example, two air conditioners (outside air conditioners) for treating the outside air are installed. Each air conditioner 11 has a cooling coil (not shown) that cools the air to generate cooling air, and the air supply speed of the cooling air is variable between 10 and 35 m / s depending on the thermal load in the room. And a blower with an inverter (not shown) whose rotational speed is controlled as described above. The air conditioner 11 is cascade controlled so that the supply temperature of the cooling air becomes a predetermined temperature (for example, 16 ° C.).

給気ダクト１２は、同一高さ（例えば、床上９ｍの高さ）で水平且つ平行に並設される２本一対の直線ダクト１４と、直線ダクト１４と各空調機１１との間に配設される接続ダクト１５と、を備えている。   The air supply duct 12 is disposed between a pair of two straight ducts 14 arranged in parallel and horizontally at the same height (for example, a height of 9 m above the floor), and between the straight ducts 14 and the air conditioners 11. Connecting duct 15 to be provided.

複数の吹出口１３は、それぞれ、直線ダクト１４上に所定間隔で立設されるフレキシブルダクトと、フレキシブルダクトの上端に固定される１００％開口のノズルと、を備えて構成されている。同一列の直線ダクト１４上の複数の吹出口１３はそれぞれ同一向き斜め上方に同一角度で傾斜した姿勢を成し、吹出口群を形成している。そして、一方の列の吹出口群の吹出口１３と、該一方の列に対向する他方の列の吹出口群の吹出口１３は、図１において実線の矢印で示すように、それぞれ近接方向中央斜め上方に空気を吹き上げるように互いに逆向きに傾斜している。   Each of the plurality of air outlets 13 includes a flexible duct erected on the straight duct 14 at a predetermined interval and a 100% open nozzle fixed to the upper end of the flexible duct. The plurality of air outlets 13 on the straight ducts 14 in the same row are inclined in the same direction and obliquely upward at the same angle to form an air outlet group. And the blower outlet 13 of the blower outlet group of one row | line | column and the blower outlet 13 of the blower blower group of the other row | line | column which opposes this one row | line | column are each a proximity | contact direction center, as shown by the solid line arrow in FIG. They are inclined in opposite directions so as to blow air upward obliquely.

吹出口１３の傾斜角度は、互いに対向している吹出口群間の距離や吹出口１３から天井までの距離に応じて、垂直方向に対して５〜４５°の範囲に設定されるのが好ましい。上記したように吹出口１３はフレキシブルダクトで構成されているため、簡単に吹出口１３の傾斜角度を調整することができる。また、フレキシブルダクトの外面を押圧することで、内部の開口面積を任意に変更することができ、各吹出口１３からの風量を簡単に調整することができる。   The inclination angle of the air outlet 13 is preferably set in the range of 5 to 45 ° with respect to the vertical direction according to the distance between the air outlet groups facing each other and the distance from the air outlet 13 to the ceiling. . As described above, since the air outlet 13 is formed of a flexible duct, the inclination angle of the air outlet 13 can be easily adjusted. Moreover, an internal opening area can be changed arbitrarily by pressing the outer surface of a flexible duct, and the air volume from each blower outlet 13 can be adjusted easily.

また、大空間用空調システム１０は、空調空間Ｓａに臨むように壁面１６の下部に設けられる下部吸込口１７と、壁面１６に沿って鉛直方向に形成される吸込みチャンバー１８と、吸込みチャンバー１８と空調機１１とを接続する還気ダクト１９と、空調管理外空間Ｓｂの上部に設けられる上部吸込口２０と、を備えている。上部吸込口２０は、空調機１１に還気ダクト２１を介して取り付けられるか、或いは、空調機１１の本体に直接取り付けられている。   The large space air conditioning system 10 includes a lower suction port 17 provided at a lower portion of the wall surface 16 so as to face the air conditioning space Sa, a suction chamber 18 formed in a vertical direction along the wall surface 16, and a suction chamber 18. A return air duct 19 for connecting the air conditioner 11 and an upper suction port 20 provided in the upper part of the air conditioning management outside space Sb are provided. The upper suction port 20 is attached to the air conditioner 11 via the return air duct 21 or directly attached to the main body of the air conditioner 11.

図１の左側及び右側にそれぞれ示されているように、１台の空調機１１に対して、下部吸込口１７と上部吸込口２０の両方の吸込口を設ける場合には、還気ダクト１９，２１にそれぞれ電動ダンパー２２，２３を設置し、例えば、冬期に下部吸込口１７を使用して夏期に上部吸込口２０を使用する等、電動ダンパー２２，２３を切替え制御することもできる。   As shown on the left and right sides of FIG. 1, when both the lower suction port 17 and the upper suction port 20 are provided for one air conditioner 11, the return air duct 19, The electric dampers 22 and 23 may be respectively installed in 21 and the electric dampers 22 and 23 may be switched and controlled, for example, using the lower inlet 17 in the winter and the upper inlet 20 in the summer.

さらに、大空間用空調システム１０は、特に図示しないが、空調管理外空間Ｓｂに設置される所定台数（例えば、２台）の外気処理用の空調機（以下「外調機」と称す。）と、該外調機によって外部から取り込まれた空気を空調管理外空間Ｓｂにおいて斜め上方に向けて吹き出す複数の給気口と、を備えている。   Further, although not particularly illustrated, the large space air conditioning system 10 is a predetermined number (for example, two) of outside air processing air conditioners (hereinafter referred to as “external air conditioners”) installed in the air conditioning management outside space Sb. And a plurality of air supply ports for blowing air taken in from the outside by the external air conditioner obliquely upward in the air conditioning management outside space Sb.

次に、上記した構成を備えた大空間用空調システム１０の作用について説明する。   Next, the operation of the large space air conditioning system 10 having the above-described configuration will be described.

各ゾーンの空調機１１において、所定温度（例えば、１６℃）に冷却されて送出された冷房用空気は、接続ダクト１５及び２本一対の直線ダクト１４を通り、図１において実線の矢印で示すように、対向する各吹出口１３からそれぞれ中央斜め上方に向かって空調管理外空間Ｓｂに吹き出される。   In the air conditioners 11 of each zone, the cooling air cooled and sent to a predetermined temperature (for example, 16 ° C.) passes through the connection duct 15 and the pair of two straight ducts 14 and is indicated by solid arrows in FIG. In this way, each of the air outlets 13 facing each other is blown out into the air-conditioning management outside space Sb obliquely upward in the center.

このように空調管理外空間Ｓｂに吹き出された冷房用空気は、空調空間Ｓａから自然上昇した工作機械Ｍの廃熱を含む室内空気を誘引混合しながら上昇する。この時、冷房用空気は、同一列の吹出口群から同一向き斜め上方に吹き出されて面状の気流が形成されると共に、この気流の方向が工作機械Ｍの廃熱を含む上昇気流と同一であるため、該上昇気流を起こし易く、冷房用空気と上昇気流との混合効率を高めることができ、見かけ上の循環回数を従来と比較して大幅に削減することができる。   Thus, the air for cooling blown out to the air-conditioning management outside space Sb rises while attracting and mixing the room air including the waste heat of the machine tool M naturally rising from the air-conditioning space Sa. At this time, the air for cooling is blown obliquely upward in the same direction from the group of outlets in the same row to form a planar air flow, and the direction of the air flow is the same as the rising air flow including the waste heat of the machine tool M. Therefore, the updraft is likely to occur, the mixing efficiency of the cooling air and the updraft can be increased, and the apparent number of circulations can be greatly reduced as compared with the conventional case.

このように工作機械Ｍの廃熱を含む室内空気と混合して均一の温度となった空気は、比重が重くなることで、空調管理外空間Ｓｂから空調空間Ｓａに自然に降下して空調空間Ｓａに供給される。その後、空気は、下部吸込口１７又は上部吸込口２０を介して空調機１１に戻され、前記冷却コイルで冷却された後、前記送風機によって空調管理外空間Ｓｂ内に吹き出され、循環気流が形成される。   Thus, the air that has been mixed with the room air containing the waste heat of the machine tool M and has a uniform temperature naturally descends from the air-conditioning management outside space Sb to the air-conditioning space Sa due to the increased specific gravity. Supplied to Sa. After that, the air is returned to the air conditioner 11 through the lower suction port 17 or the upper suction port 20, cooled by the cooling coil, and then blown out into the air conditioning management outside space Sb by the blower, thereby forming a circulating airflow. Is done.

また、空調空間Ｓａから自然上昇した室内空気を誘引混合した冷房用空気の一部分は、排風機（図示省略）を介して外部に排出される。一方、この排出された空気と同一風量の空気が該外調機を介して外部から取り込まれ、前記給気口から斜め上方に向かって空調管理外空間Ｓｂ内に供給され、空調空間Ｓａから自然上昇した空気と混合される。   Moreover, a part of the air for cooling which attracted and mixed the indoor air which naturally rose from the air-conditioned space Sa is discharged to the outside through an air exhaust (not shown). On the other hand, air having the same air volume as the discharged air is taken in from the outside through the external air conditioner, and is supplied obliquely upward from the air supply port into the air conditioning management outside space Sb. Mixed with elevated air.

According to these analysis results, it is said that almost all (approximately 90%) of the air-conditioned space Sa (space up to 6 m above the floor) falls within the required temperature range (23 ° C. ± 1 ° C.). Good results could be obtained.

Good results could be obtained.

上記したように本発明の実施の形態に係る大空間用空調システム１０によれば、工作機械Ｍからの廃熱量が多い程、廃熱を含む室内空気が早い時間で上昇してしまうため、工作機械Ｍの廃熱が与える空調空間Ｓａの温度への影響は少ない。また、発熱の多いエリアでは、上昇気流が多く発生する分、空調空間Ｓａの所定温度（２３℃±１℃）に保持された周辺空気が多く誘引される一方、発熱量の少ないエリアでは、空気の誘引量が少なく、空気の動きも少ない。また、発熱量の多いエリアであっても、工作機械Ｍが停止すると上昇気流も停止するため、発熱のないエリアと同じように空気が動かなくなる。さらに、工作機械Ｍからの廃熱は、誘引気流と共に上昇するため、水平移動が少なくなり、乱流を発生させることがなく、熱負荷を拡散させることがない。   As described above, according to the large space air conditioning system 10 according to the embodiment of the present invention, the greater the amount of waste heat from the machine tool M, the faster the indoor air including waste heat rises. The influence of the waste heat of the machine M on the temperature of the air-conditioned space Sa is small. Further, in the area where much heat is generated, a large amount of ascending airflow is generated, so that a large amount of the ambient air held at the predetermined temperature (23 ° C. ± 1 ° C.) of the air-conditioned space Sa is attracted. The amount of attraction is small, and there is little air movement. Even in an area where the amount of heat generation is large, when the machine tool M is stopped, the ascending air current is also stopped. Furthermore, since the waste heat from the machine tool M rises with the induced airflow, horizontal movement is reduced, turbulence is not generated, and heat load is not diffused.

以上より、空調空間Ｓａにおける発熱量の多いエリアの温度と発熱量の少ないエリアの温度は均衡し、両エリア間における空調環境の差異は少ない。また、加工機械Ｍの廃熱を含む上昇気流と吹出口１３から高速で吹き出される冷房用空気を空調空間Ｓａの上部で効果的に混合させることができるため、空調空間Ｓａにおける給気風量を削減することができ、省エネルギー化を図ることができる。さらに、空調空間Ｓａの上方で冷房用空気と上昇室内気流とを混合させているため、空調機１１の給気温度制御を厳密に行わなくても空調空間Ｓａの温度分布を良好に維持することが可能となり、厳密な冷水温度制御や応答性の良い電気ヒータを使用する必要がない。したがって、低コスト化と、省エネルギー化と、高品質化を同時に実現することが可能となる。   As described above, the temperature of the area with a large amount of heat generation in the air-conditioned space Sa and the temperature of the area with a small amount of heat generation are balanced, and the difference in the air-conditioning environment between the two areas is small. In addition, since the ascending air flow including the waste heat of the processing machine M and the cooling air blown out from the air outlet 13 at high speed can be effectively mixed in the upper part of the air-conditioned space Sa, the amount of air supplied in the air-conditioned space Sa can be reduced. It is possible to reduce the energy consumption. Further, since the cooling air and the rising indoor airflow are mixed above the air-conditioned space Sa, the temperature distribution of the air-conditioned space Sa can be maintained well without strictly controlling the supply air temperature of the air conditioner 11. Therefore, it is not necessary to use an electric heater with strict cooling water temperature control and good response. Therefore, cost reduction, energy saving, and high quality can be realized at the same time.

また、高速ダクトシステムを採用し、複数の吹出口１３を１列に直線状に並べることで大きな誘引気流を生成することができるため、大空間Ｓの柱間距離が長くても、ダクトを延長する必要がなく、施工コストの低減化及び空調設備の設置スペースの縮小化を図ることができる。   In addition, a high-speed duct system is adopted, and a large induced airflow can be generated by arranging a plurality of outlets 13 in a straight line, so that the duct is extended even if the distance between the columns of the large space S is long. Therefore, it is possible to reduce the construction cost and the installation space of the air conditioning equipment.

また、空調空間Ｓａに供給される冷房用空気は、空調管理外空間Ｓｂからの下降気流であり、大型の工作機械Ｍや生産設備の周囲に確実に到達して気流の死角がなくなるため、工作機械Ｍの性能を高く維持することができる。また、吹出口１３は、高所の空調管理外空間Ｓｂに設置される上、斜め上方に冷房用空気を吹き出すため、吹出口１３直近の風速が速くても、低層域である空調空間Ｓａ内の気流速度を低く抑えることができ、空調空間Ｓａ内での作業に支障が生じる虞がなく、作業環境の改善を図ることができる。   In addition, the cooling air supplied to the air-conditioned space Sa is a descending airflow from the air-conditioning control outside space Sb, and reliably reaches the periphery of the large machine tool M and the production equipment, so that the blind spot of the airflow disappears. The performance of the machine M can be maintained high. In addition, since the air outlet 13 is installed in the high air conditioning management outside space Sb and the air for cooling is blown obliquely upward, even in the case where the wind speed in the immediate vicinity of the air outlet 13 is fast, the air outlet space Sa is in a low-rise area. The air velocity can be kept low, there is no possibility that the work in the air-conditioned space Sa will be hindered, and the work environment can be improved.

さらに、空調機１１、給気ダクト１２、及び吹出口１３等の空調設備は、空調管理外空間Ｓｂにおいて、工作機械Ｍ等の生産装置の配置に無関係に配置することができるため、工作機械Ｍの配置換え等によって空調空間Ｓａ内の熱負荷に変動が生じたとしても、ダクトや配管の大掛かりな改修工事を行う必要がなく、単に、吹出口１３の数を増減したり、１個の吹出口１３が担当するエリアを変更したりすることで比較的簡単に対応することができる。また、空調設備が空調空間Ｓａの壁面に設置されていないため、工作機械Ｍの配置を自由に決定したり、変更したりすることができ、フレキシブル性を高めることができる。さらに、大空間Ｓの天井高さは、ある程度の高さを有していれば、天井高さの違いによって、空調空間Ｓａの環境（温度、風速）が不利になる要素がなく、本システムを適用可能な用途を拡大することができる。   Furthermore, since the air conditioning equipment such as the air conditioner 11, the air supply duct 12, and the air outlet 13 can be arranged in the space outside the air conditioning management Sb regardless of the arrangement of the production device such as the machine tool M, the machine tool M Even if the thermal load in the air-conditioned space Sa fluctuates due to rearrangement, etc., there is no need to perform extensive repair work of ducts and piping, simply increasing or decreasing the number of outlets 13 or one blower It is possible to respond relatively easily by changing the area in which the exit 13 is in charge. Moreover, since the air-conditioning equipment is not installed on the wall surface of the air-conditioned space Sa, the arrangement of the machine tool M can be freely determined or changed, and flexibility can be enhanced. Furthermore, if the ceiling height of the large space S has a certain height, there is no element that adversely affects the environment (temperature, wind speed) of the air-conditioned space Sa due to the difference in the ceiling height. Applicable applications can be expanded.

なお、上記した本発明の実施の形態の説明では、２０００ｍ２の床面積と１７ｍの天井高さを有し、床上６ｍまでの高さの空間が空調空間Ｓａに設定されている大空間Ｓに大空間用空調システム１０を設置した場合について例示したが、本発明は、１００ｍ２程度以上の床面積と６ｍ程度以上の天井高さを有する天井高さの高い大空間Ｓであれば、適用可能である。また、吹出口１３は、冷房用空気を強制的に上方に向けて吹き出すように設けられていれば、必ずしも、斜め上方に傾斜した姿勢で設けられていなくてもよい。 In the description of the embodiment of the present invention described above, a large space S having a floor area of 2000 m 2 and a ceiling height of 17 m and a height of 6 m above the floor is set as the air-conditioned space Sa. Although illustrated about the case where the air conditioning system 10 for large spaces was installed, this invention is applicable if it is the large space S with a high ceiling height which has a floor area of about 100 m < 2 > or more and a ceiling height of about 6 m or more. It is. Further, the air outlet 13 is not necessarily provided in a posture inclined obliquely upward as long as the air for cooling is provided so as to be forced upward.

上記したように大空間用空調システム１０を適用可能な大空間Ｓの天井高さを６ｍ程度に設定した根拠は、図１２に示すように、空調空間Ｓａの天井高さＨが機器を設置するために最低３ｍ必要であり、空調管理外空間Ｓｂの天井高さＨが空調設備を設置するために最低３ｍ必要であるからである。   As described above, the reason why the ceiling height of the large space S to which the large space air conditioning system 10 can be applied is set to about 6 m is that the ceiling height H of the air conditioning space Sa installs the equipment as shown in FIG. This is because a minimum height of 3 m is required and the ceiling height H of the outside air conditioning management space Sb is 3 m in order to install the air conditioning equipment.

また、大空間用空調システム１０を適用可能な大空間Ｓの床面積を１００ｍ２程度に設定した根拠は、図１２に示すように、互いに対向する吹出口１３から吹き出される上昇気流が両側にそれぞれ３０°広がることから、上昇気流のための空間幅Ｄ１はそれぞれ１．２Ｈ必要であり、空調空間Ｓａに向かう下降気流のための空間幅Ｄ２は上昇気流のための空間幅Ｄ１と同様にそれぞれ１．２Ｈ必要であるから、全体幅で最低４．８Ｈ（４．８×３＝１４．４ｍ≒１５ｍ）必要となる。そして、大空間Ｓを備える建物の奥行き幅の１スパンは構造上６〜８ｍとなるのが一般的であるため、全体幅（１５ｍ）と奥行き幅（６ｍ〜８ｍ）とを乗じることで大空間Ｓの床面積が９０ｍ２〜１２０ｍ２となるからである。 Moreover, the grounds for setting the floor area of the large space S to which the large space air conditioning system 10 can be applied to about 100 m 2 are as shown in FIG. Since each of them expands by 30 °, the space width D1 for the updraft needs 1.2H, and the space width D2 for the downflow toward the air-conditioned space Sa is the same as the space width D1 for the updraft, respectively. Since 1.2H is required, the total width is required to be at least 4.8H (4.8 × 3 = 14.4 m≈15 m). And, since one span of the depth width of the building having the large space S is generally 6 to 8 m in terms of structure, the large space can be obtained by multiplying the overall width (15 m) and the depth width (6 m to 8 m). floor area S is because the 90m 2 ~120m 2.

本発明の技術は、上記した金属加工工場等の各種工場の他、単位面積当たりの冷熱量よりも機器からの発熱量の方が相当大きく、室内環境を所定範囲内に維持するために機器等の発熱体からの廃熱の除去が必要となる天井高さの高い大空間を有するデータセンターなど、他の用途の建造物にも利用が見込まれるものである。   The technology of the present invention is not limited to the above-described various factories such as metal processing factories, and the amount of heat generated from the equipment is considerably larger than the amount of cold heat per unit area, and the equipment etc. to maintain the indoor environment within a predetermined range. It is expected to be used in buildings for other purposes, such as data centers with large spaces with high ceiling height that require the removal of waste heat from the heating elements.
