Description

空気調和装置Air conditioner
　本発明は、空気調和装置に関する。 The present invention relates to an air conditioner.
　半導体製造設備等において用いられる精密温調用の空気調和装置として、空気取込口及び空気吐出口を有する筐体を備え、当該筐体内に送風機、加熱部及び冷却部を収容する空気調和装置がある。このような空気調和装置は、送風機の駆動によって装置外部から空気取込口に空気を取り込み、取り込んだ空気を加熱部及び冷却部によって所望の温度に調節して空気吐出口から吐出する。空気取込口及び空気吐出口は、筐体の任意の位置に設けられ得るが、多くの場合、空気取込口は筐体の側面に設けられ、空気吐出口は筐体の上面又は側面に設けられている（例えば、特許文献１参照）。 As an air conditioner for precise temperature control used in semiconductor manufacturing facilities, etc., there is an air conditioner that includes a housing having an air intake port and an air discharge port and houses a blower, a heating unit, and a cooling unit in the housing. . Such an air conditioner takes air from the outside of the apparatus by driving the blower, adjusts the taken air to a desired temperature by a heating unit and a cooling unit, and discharges the air from the air discharge port. The air intake port and the air discharge port can be provided at any position on the housing, but in many cases, the air intake port is provided on the side surface of the housing, and the air discharge port is provided on the upper surface or side surface of the housing. (For example, refer to Patent Document 1).
　この種の空気調和装置は、一般に、空気吐出口にダクトを接続することにより、温度制御された空気をダクトを介して温度制御対象空間に供給するように用いられる。また、ダクトの下流側端部に複数の穴を有する中空のボックスを接続し、当該ボックスにおける複数の穴に分岐用のダクトを接続することにより、温度制御された空気を複数の温度制御対象空間に供給する場合もある。例えば半導体製造設備においては、上記のようなボックスを用いることで、一つの空気調和装置から吐出される空気を、クリーンルーム及び当該クリーンルーム内に設置された複数の装置の内部等に分配する場合がある。 This type of air conditioner is generally used to supply temperature-controlled air to a temperature control target space through a duct by connecting a duct to an air discharge port. Further, by connecting a hollow box having a plurality of holes to the downstream end of the duct, and connecting a branching duct to the plurality of holes in the box, the temperature-controlled air is converted into a plurality of temperature control target spaces. There is also a case to supply to. For example, in a semiconductor manufacturing facility, by using a box as described above, air discharged from one air conditioner may be distributed to a clean room and a plurality of apparatuses installed in the clean room. .
　また、半導体製造設備において用いられる際、この種の空気調和装置は前記設備が設置される空間の階下の空間に配置される場合がある。この場合においては、空気吐出口に接続されたダクトが、階上の空間に向けて上方に延びるように配置されることになる。 Also, when used in a semiconductor manufacturing facility, this type of air conditioner may be arranged in a space below the space where the facility is installed. In this case, the duct connected to the air discharge port is arranged so as to extend upward toward the space on the floor.
特開２００９－６３２４２号公報JP 2009-63242 A
　ところで、特許文献１に開示された空気調和装置では、一つの空気吐出口が筐体の上面又は側面に設けられているが、この構成では、空気吐出口から温度制御対象空間に向けてダクトを延ばす場合に、ダクトを不所望に多く屈曲させなければならない状況が生じ得る。そのため、ダクトの屈曲部分の増加による圧損の増加によって、所望の風量を得るための送風機の出力を不所望に増加させなければならない状況が生じ、送風機の運転効率が低下する場合がある。具体的には例えば、筐体の側面に空気吐出口が設けられ且つ温度制御対象空間が空気調和装置に対して上方に位置する場合、ダクトを上方に屈曲させる必要がある。この場合、ダクトを直線的に延ばせる場合に比較して圧損が増加することで、送風機の運転効率が低下する。 By the way, in the air conditioner disclosed in Patent Document 1, one air discharge port is provided on the upper surface or side surface of the housing. In this configuration, a duct is provided from the air discharge port toward the temperature control target space. When extending, situations may arise where the duct must be bent undesirably many times. For this reason, an increase in pressure loss due to an increase in the bent portion of the duct may cause a situation in which the output of the blower for obtaining a desired air volume must be increased undesirably, which may reduce the operation efficiency of the blower. Specifically, for example, when the air discharge port is provided on the side surface of the housing and the temperature control target space is located above the air conditioner, the duct needs to be bent upward. In this case, the operating loss of the blower is reduced by increasing the pressure loss as compared with the case where the duct is extended linearly.
　また、この種の空気調和装置では、空気吐出口に接続するダクトとして、一般的に、空気吐出口の直径に合致する直径のダクトが用いられる。ここで、特許文献１に開示されるように、装置の上面又は側面に空気吐出口が一つのみ設けられている構成では、設置条件によっては、ダクトの占有領域が不所望に大きくなってしまい、空気調和装置の設置自由度が制約される状況や、当該装置の周辺部材の配置自由度が制約される状況が生じる場合がある。また、温度制御対象空間に求められる要求風量に対してダクトが小さくなり過ぎることで、送風機の出力を不所望に増加させなければならない状況も生じ得る。 In this type of air conditioner, a duct having a diameter that matches the diameter of the air discharge port is generally used as the duct connected to the air discharge port. Here, as disclosed in Patent Document 1, in the configuration in which only one air discharge port is provided on the upper surface or side surface of the device, the occupied area of the duct becomes undesirably large depending on the installation conditions. There may be a situation where the degree of freedom of installation of the air conditioner is restricted or the degree of freedom of arrangement of peripheral members of the equipment is restricted. Moreover, the duct may become too small with respect to the required air volume required for the temperature control target space, so that a situation where the output of the blower must be increased undesirably may occur.
　また、空気調和装置から複数の温度制御対象空間に空気を供給する際には、上述したように、空気吐出口に接続したダクトの下流側端部に複数の穴を有する中空のボックスを接続し、且つ当該ボックスにおける複数の穴に分岐用のダクトを接続してもよい。しかしながら、この場合、ダクトの増加によるコスト上昇及び構成の煩雑化という問題が生じる。そのため、構造を煩雑化することなく複数の空間に空気を供給可能な構成が望まれる。 Further, when supplying air from the air conditioner to a plurality of temperature control target spaces, as described above, a hollow box having a plurality of holes is connected to the downstream end of the duct connected to the air discharge port. In addition, a branching duct may be connected to a plurality of holes in the box. However, in this case, there arises a problem that the cost increases due to an increase in the number of ducts and the configuration becomes complicated. Therefore, a configuration that can supply air to a plurality of spaces without complicating the structure is desired.
　本発明は、このような実情を考慮してなされたものであり、温度制御対象空間へ空気を供給するためのダクトを種々のパターンで接続することができ、状況に応じて好適なダクトの配置パターンを柔軟に設定することができる空気調和装置を提供することを目的とする。 The present invention has been made in consideration of such circumstances, and ducts for supplying air to the temperature control target space can be connected in various patterns, and suitable arrangement of the ducts according to the situation. An object of the present invention is to provide an air conditioner capable of flexibly setting a pattern.
　本発明は、空気を取り込む空気取込口及び取り込まれた空気を吐出する空気吐出口を有し、その内部に前記空気取込口と前記空気吐出口とを連通させる空気通流路を画成する筐体と、前記空気取込口から前記空気吐出口へ空気を通流させる送風機と、前記筐体に収容され、前記空気通流路を通流する空気を温度制御する温調部と、前記空気吐出口を覆うように前記筐体に取り付けられ、且つその内部空間を前記空気吐出口に連通させる分配ボックスと、を備え、前記分配ボックスには、ダクトが接続される穴であって、前記内部空間から前記ダクトへ空気を供給するための、上方に開口する第１ダクト接続穴と、前記第１ダクト接続穴とは異なる方向に開口する第２ダクト接続穴と、が設けられている、ことを特徴とする空気調和装置、である。 The present invention has an air intake port for taking in air and an air discharge port for discharging the taken-in air, and defines an air passage for connecting the air intake port and the air discharge port therein. A housing that conducts air from the air intake port to the air outlet, a temperature control unit that controls the temperature of the air that is housed in the housing and flows through the air passage, A distribution box that is attached to the housing so as to cover the air discharge port and communicates the internal space with the air discharge port, and the distribution box is a hole to which a duct is connected, A first duct connection hole that opens upward and a second duct connection hole that opens in a direction different from the first duct connection hole for supplying air from the internal space to the duct are provided. An air conditioner, characterized by That.
　この空気調和装置によれば、接続されたダクトを温度制御対象空間まで延ばす際にダクトの屈曲部分を極力抑制できるダクト接続穴を、上方に開口する第１ダクト接続穴及びこれとは異なる方向に開口する第２ダクト接続穴の中から温度制御対象空間の位置に応じて適宜選択することが可能となる。これにより、ダクトに形成される不所望な屈曲部分による圧損の増加を抑制できることで、送風機の運転効率の低下を抑制できる。また、複数の温度制御対象空間がある場合には、複数のダクト接続穴に接続したダクトを対応する温度制御対象空間まで延ばすことにより、ダクトの増加を抑制しつつ複数の温度制御対象空間に温度制御された空気を供給できる。したがって、温度制御対象空間へ空気を供給するためのダクトを種々のパターンで接続することができ、状況に応じて好適なダクトの配置パターンを柔軟に設定することができる。 According to this air conditioner, when the connected duct is extended to the temperature control target space, the duct connection hole that can suppress the bent portion of the duct as much as possible is formed in the first duct connection hole that opens upward and in a different direction. It is possible to appropriately select the second duct connection hole that is open according to the position of the temperature control target space. Thereby, the fall of the operating efficiency of an air blower can be suppressed because the increase in the pressure loss by the undesirable bending part formed in a duct can be suppressed. In addition, when there are multiple temperature control target spaces, the ducts connected to the multiple duct connection holes are extended to the corresponding temperature control target spaces, thereby suppressing the increase in the ducts and controlling the temperature in the multiple temperature control target spaces. Can supply controlled air. Therefore, ducts for supplying air to the temperature control target space can be connected in various patterns, and a suitable duct arrangement pattern can be flexibly set according to the situation.
　本発明に係る空気調和装置においては、前記分配ボックスに、複数の前記第１ダクト接続穴が設けられていてもよい。
　この構成によれば、ダクトを通して直接的に空気を供給できる温度制御対象空間を増加させることができるため、利便性を向上させることができる。 In the air conditioning apparatus according to the present invention, a plurality of the first duct connection holes may be provided in the distribution box.
According to this configuration, it is possible to increase the temperature control target space in which air can be directly supplied through the duct, so that convenience can be improved.
　また、複数の前記第１ダクト接続穴のうちの少なくとも一つ（一部）の第１ダクト接続穴の開口面積が、他の第１ダクト接続穴の開口面積と異なっていてもよい。
　この構成によれば、ダクトの占有領域を小さくすることが求められる場合には、開口面積の小さい第１ダクト接続穴に細いダクトを接続することにより、占有面積抑制の要求に対応することができ、温度制御対象空間に求められる要求風量が大きい場合には、開口面積の大きい第１ダクト接続穴に太いダクトを接続することにより、圧損による送風機の不所望な出力増加を抑制しつつ温度制御対象空間に空気を供給できる。これにより、状況に応じて好適なダクトの配置パターンをより柔軟に設定することができ、利便性を向上させることができる。 In addition, an opening area of at least one (part) of the first duct connecting holes among the plurality of first duct connecting holes may be different from an opening area of the other first duct connecting holes.
According to this configuration, when it is required to reduce the occupied area of the duct, it is possible to meet the demand for suppressing the occupied area by connecting the thin duct to the first duct connecting hole having a small opening area. When the required air volume required for the temperature control target space is large, a thick duct is connected to the first duct connection hole having a large opening area, thereby suppressing an undesired increase in the output of the blower due to pressure loss. Air can be supplied to the space. Thereby, the arrangement pattern of a suitable duct can be set more flexibly according to a situation, and the convenience can be improved.
　また、前記分配ボックスに、複数の前記第２ダクト接続穴が設けられていてもよい。
　この構成によれば、ダクトを通して直接的に空気を供給できる温度制御対象空間を増加させることができるため、利便性を向上させることができる。 A plurality of the second duct connection holes may be provided in the distribution box.
According to this configuration, it is possible to increase the temperature control target space in which air can be directly supplied through the duct, so that convenience can be improved.
　この場合、複数の前記第２ダクト接続穴のうちの少なくとも一つ（一部）の第２ダクト接続穴が、他の第２ダクト接続穴とは異なる方向に開口していてもよい。
　この構成によれば、例えば、互いに異なる方向に開口する複数の第２ダクト接続穴の中から、接続されたダクトを温度制御対象空間まで延ばす際にダクトの長さを極力抑制できるダクト接続穴を、温度制御対象空間の位置に応じて適宜選択することが可能となる。これにより、状況に応じて好適なダクトの配置パターンをより柔軟に設定することができ、利便性を向上させることができる。 In this case, at least one (a part) of the plurality of second duct connection holes may be opened in a direction different from that of the other second duct connection holes.
According to this configuration, for example, the duct connection hole that can suppress the length of the duct as much as possible when extending the connected duct to the temperature control target space from among the plurality of second duct connection holes that open in different directions. Thus, it is possible to select appropriately according to the position of the temperature control target space. Thereby, the arrangement pattern of a suitable duct can be set more flexibly according to a situation, and the convenience can be improved.
　また、この場合、異なる方向に開口する前記第２ダクト接続穴の開口面積が、互いに異なっていてもよい。

The air volume adjustment damper 101 in this embodiment is manually and automatically returned. The air volume of the air flowing through the flow path 100 can be adjusted. Details of the distribution box 80 will be described later.
　次に、冷却部２及び加熱部４について図２を参照しつつ説明する。まず冷却部２について説明すると、本実施の形態における冷却部２は、第１冷却ユニット１０の冷却コイル１４と、第２冷却ユニット２０の冷却コイル２４と、で構成されている。本実施の形態において、冷却コイル１４を含む第１冷却ユニット１０は、可変運転周波数で運転され回転数を調節可能な圧縮機１１、凝縮器１２、膨張弁１３、及び冷却コイル１４が熱媒体を循環させるように当該順序で配管１５により接続されることにより構成されており、冷却コイル２４を含む第２冷却ユニット２０は、可変運転周波数で運転され回転数を調節可能な圧縮機２１、凝縮器２２、膨張弁２３、及び冷却コイル２４が熱媒体を循環させるように当該順序で配管２５により接続されることにより構成されている。 Next, the cooling unit 2 and the heating unit 4 will be described with reference to FIG. First, the cooling unit 2 will be described. The cooling unit 2 in the present embodiment includes a cooling coil 14 of the first cooling unit 10 and a cooling coil 24 of the second cooling unit 20. In the present embodiment, the first cooling unit 10 including the cooling coil 14 is operated at a variable operating frequency, and the compressor 11, the condenser 12, the expansion valve 13, and the cooling coil 14 that can adjust the rotation speed serve as a heat medium. The second cooling unit 20 including the cooling coil 24 is configured to be circulated so as to be circulated, and the second cooling unit 20 including the cooling coil 24 is operated at a variable operating frequency and can adjust the rotation speed. 22, the expansion valve 23, and the cooling coil 24 are connected by a pipe 25 in this order so as to circulate the heat medium.
　これら第１及び第２冷却ユニット１０，２０において、圧縮機１１，２１は、冷却コイル１４，２４から流出した低温かつ低圧の気体の状態の熱媒体を圧縮し、高温かつ高圧の気体の状態として、凝縮器１２，２２に供給する。圧縮機１１，２１は、可変運転周波数で運転され運転周波数に応じて回転数を調節可能なインバータ圧縮機である。圧縮機１１，２１では、運転周波数が高いほど、より多くの熱媒体が凝縮器１２，２２に供給されるようになっている。圧縮機１１としては、インバータとモータとを一体に有するスクロール型圧縮機が採用されることが好ましい。しかしながら、インバータによる運転周波数の調節により回転数を調節して熱媒体の供給量（流量）を調節可能であれば、圧縮機１１，２１の形式は特に限定されるものではない。 In the first and second cooling units 10 and 20, the compressors 11 and 21 compress the low-temperature and low-pressure gas heat medium flowing out from the cooling coils 14 and 24 to form a high-temperature and high-pressure gas state. To the condensers 12 and 22. The compressors 11 and 21 are inverter compressors that are operated at a variable operating frequency and whose rotation speed can be adjusted according to the operating frequency. In the compressors 11 and 21, more heat medium is supplied to the condensers 12 and 22 as the operating frequency is higher. As the compressor 11, it is preferable to employ a scroll compressor that integrally includes an inverter and a motor. However, the types of the compressors 11 and 21 are not particularly limited as long as the number of rotations can be adjusted by adjusting the operation frequency by the inverter to adjust the supply amount (flow rate) of the heat medium.
　また、凝縮器１２，２２は、圧縮機１１，２１で圧縮された熱媒体を冷却水によって冷却すると共に凝縮し、所定の冷却温度の高圧の液体の状態として、膨張弁１３，２３に供給するようになっている。凝縮器１２，２２の冷却水には、水が用いられてよいし、その他の冷媒が用いられてもよい。また、膨張弁１３，２３は、凝縮器１２，２２から供給された熱媒体を膨張させることにより減圧させて、低温かつ低圧の気液混合状態として、冷却コイル１４，２４に供給するようになっている。冷却コイル１４，２４は、供給された熱媒体を温度制御対象の空気と熱交換させて空気を冷却するようになっている。空気と熱交換した熱媒体は、低温かつ低圧の気体の状態となって冷却コイル１４，２４から流出して再び圧縮機１１，２１で圧縮されるようになっている。 The condensers 12 and 22 cool the heat medium compressed by the compressors 11 and 21 with cooling water and condense them, and supply them to the expansion valves 13 and 23 as a high-pressure liquid at a predetermined cooling temperature. It is like that. Water may be used for the cooling water of the condensers 12 and 22, or other refrigerants may be used. The expansion valves 13 and 23 are decompressed by expanding the heat medium supplied from the condensers 12 and 22, and are supplied to the cooling coils 14 and 24 in a low-temperature and low-pressure gas-liquid mixed state. ing. The cooling coils 14 and 24 are configured to heat-exchange the supplied heat medium with air to be temperature controlled and cool the air. The heat medium exchanged with air becomes a low-temperature and low-pressure gas state, flows out of the cooling coils 14 and 24, and is compressed again by the compressors 11 and 21.
　以上のような各冷却ユニット１０，２０では、圧縮機１１，２１の運転周波数を変化させ回転数を調節することにより、凝縮器１２，２２に供給される熱媒体の供給量を調節可能であると共に、膨張弁１３，２３の開度を調節可能であることで、冷却コイル１４，２４に供給される熱媒体の供給量を調節可能となっている。このような調節により冷凍能力が可変となっている。なお、本実施の形態では、制御の安定性を向上させる目的で、第１冷却ユニット１０の圧縮機１１は、一定の周波数で運転される。このような運転を実施する場合には、圧縮機１１は固定周波数で運転される圧縮機であってもよく、この場合には、製造コストを低減することが可能となる。 In each of the cooling units 10 and 20 as described above, the supply amount of the heat medium supplied to the condensers 12 and 22 can be adjusted by changing the operating frequency of the compressors 11 and 21 and adjusting the rotation speed. At the same time, the opening amount of the expansion valves 13 and 23 can be adjusted, so that the supply amount of the heat medium supplied to the cooling coils 14 and 24 can be adjusted. The refrigeration capacity is variable by such adjustment. In the present embodiment, the compressor 11 of the first cooling unit 10 is operated at a constant frequency for the purpose of improving control stability. When performing such operation, the compressor 11 may be a compressor that operates at a fixed frequency, and in this case, the manufacturing cost can be reduced.
　また、冷却部２の配置態様について詳述すると、本実施の形態では、図２に示すように、空気通流路３０内に、空気通流路３０の一部を空気の流れに沿って延びて二分割する仕切り部材２００が設けられ、仕切り部材２００によって空気通流路３０の一部が、第１流路３０Ａと第２流路３０Ｂとに区画されている。そして第１流路３０Ａに、冷却部２が設けられている。また、仕切り部材２００の下流側の端部に、第１流路３０Ａ及び第２流路３０Ｂの開度を調節する流量調節ダンパ２０１が設けられている。一方で、空気取込口３１内には、上流側温度センサ４４が設けられ、上流側温度センサ４４は、リターン流路１００からの空気と合流した空気取込口３１に取り込まれた後の空気の温度を検出するようになっている。ここで、本実施の形態における流量調節ダンパ２０１は、上流側温度センサ４４が検出した温度に応じて制御ユニット５０により制御されることで、第１流路３０Ａ及び第２流路３０Ｂの開度を調節することが可能となっている。 Further, the arrangement of the cooling unit 2 will be described in detail. In the present embodiment, as shown in FIG. 2, a part of the air passage 30 extends along the air flow in the air passage 30. A partition member 200 that is divided into two parts is provided, and the partition member 200 divides a part of the air passage 30 into a first passage 30A and a second passage 30B.

　本実施の形態の空気調和装置１を運転する際には、まず、制御ユニット５０において、目標温度と目標湿度とが入力される。また、送風機６０が駆動されることにより、空気通流路３０内の空気が空気吐出口３２側に流動することにより、空気通流路３０の空気取込口３１から温度制御対象の空気が取り込まれる。さらに、各冷却ユニット１０，２０の圧縮機１１，２１も駆動される。また、この例では、送風機６０が出力する風量に対する所定の割合の風量の空気がリターン流路１００から冷却部２の上流側で且つ加熱部４の上流側の位置に戻るように、風量調節用ダンパ１０１の開度が調節されている。さらに、温度制御対象空間の位置、数、要求風量等に応じて、第１ダクト接続穴９１及び第２ダクト接続穴９２，９３のうちの所望のダクト接続穴にダクト１２０が接続される。 When operating the air conditioning apparatus 1 of the present embodiment, first, the target temperature and the target humidity are input in the control unit 50. In addition, when the blower 60 is driven, the air in the air flow passage 30 flows toward the air discharge port 32, whereby the temperature control target air is taken in from the air intake port 31 of the air flow passage 30. It is. Further, the compressors 11 and 21 of the cooling units 10 and 20 are also driven. In this example, the air volume adjustment is performed so that the air having a predetermined ratio with respect to the air volume output from the blower 60 returns from the return flow path 100 to the upstream side of the cooling unit 2 and the upstream side of the heating unit 4. The opening degree of the damper 101 is adjusted. Furthermore, the duct 120 is connected to a desired duct connection hole of the first duct connection hole 91 and the second duct connection holes 92 and 93 according to the position, number, required air volume, and the like of the temperature control target space.
　上述のように送風機６０等が駆動されると、空気通流路３０の空気取込口３１から取り込まれた空気は、上流側温度センサ４４で温度を検出された後、まず、冷却部２（第１流路３０Ａ）及び／又は第２流路３０Ｂを通過し、その後、加熱部４を通過する。その後、この空気は、加湿装置７０によって加湿された後、空気吐出口３２から吐出され、分配ボックス８０の内部空間Ｓに至る。そして、空気の一部は、第１ダクト接続穴９１及び第２ダクト接続穴９２，９３の一部又は全部を介して一つ又は複数のダクト１２０に供給される。また、空気の他の一部が、第２ダクト接続穴９４からリターン流路１００を介して冷却部２の上流側で且つ加熱部４の上流側の位置に戻る。ここで、空気吐出口３２を通過する空気は、温度センサ４１によって温度が検出され、湿度センサ４２によって湿度が検出される。そして、温度センサ４１は、検出した温度を制御ユニット５０に出力し、湿度センサ４２は、検出した湿度を制御ユニット５０に出力する。 When the blower 60 or the like is driven as described above, the air taken in from the air intake port 31 of the air passage 30 is first detected by the upstream temperature sensor 44 and then the cooling unit 2 ( It passes through the first flow path 30A) and / or the second flow path 30B, and then passes through the heating unit 4. Thereafter, the air is humidified by the humidifier 70 and then discharged from the air discharge port 32 to reach the internal space S of the distribution box 80. A part of the air is supplied to one or a plurality of ducts 120 through a part or all of the first duct connection hole 91 and the second duct connection holes 92 and 93. Further, another part of the air returns from the second duct connection hole 94 to the position upstream of the cooling unit 2 and upstream of the heating unit 4 via the return flow path 100. Here, the temperature of the air passing through the air discharge port 32 is detected by the temperature sensor 41, and the humidity is detected by the humidity sensor 42. The temperature sensor 41 outputs the detected temperature to the control unit 50, and the humidity sensor 42 outputs the detected humidity to the control unit 50.
　そして、制御ユニット５０は、温度センサ４１が検出した温度と目標温度との差分に基づいて、加熱量調節弁１８の開度、第１冷却ユニット１０の膨張弁１３の開度、第２冷却ユニット２０の膨張弁２３の開度、及び圧縮機２１の運転周波数を制御し、上記の差分に応じた加熱能力及び冷凍能力が出力されるように制御を行う。また制御ユニット５０は、湿度センサ４２が検出した湿度と目標湿度との差分に基づいて、加湿装置７０の加湿能力も制御する。 Based on the difference between the temperature detected by the temperature sensor 41 and the target temperature, the control unit 50 opens the heating amount adjusting valve 18, the opening degree of the expansion valve 13 of the first cooling unit 10, and the second cooling unit. The opening degree of the 20 expansion valves 23 and the operating frequency of the compressor 21 are controlled, and control is performed so that the heating capacity and the refrigerating capacity corresponding to the above differences are output. The control unit 50 also controls the humidification capability of the humidifier 70 based on the difference between the humidity detected by the humidity sensor 42 and the target humidity.
　そして、本実施の形態では、温度制御された空気が、第１ダクト接続穴９１及び第２ダクト接続穴９２，９３の一部又は全部を介して一つ又は複数のダクト１２０に供給され、ダクト１２０から温度制御対象空間に温度制御された空気が供給される。 In this embodiment, the temperature-controlled air is supplied to one or a plurality of ducts 120 via part or all of the first duct connection hole 91 and the second duct connection holes 92 and 93, and the duct The temperature-controlled air is supplied from 120 to the temperature control target space.
　また、このような運転の際、本実施の形態の空気調和装置１では、リターン流路１００によって、冷却部２及び加熱部４を通過した空気の一部を冷却部２の上流側で且つ加熱部４の上流側の位置に供給して、空気通流路３０の空気取込口３１に取り込まれる前の空気に合流させることができる。これにより、環境温度の著しい変動に応じて空気取込口３１に取り込まれる外部の空気の温度が大きく変動した場合であっても、この外部の空気は、温度制御されたリターン流路１００からの空気と合流することで、その温度が温度制御されるべき温度に近づくようになる。すなわち、環境変動の影響に対する影響緩和効果が生じる。そのため、外部の空気の温度の大きい変動に応じて冷凍能力又は加熱能力を急激に大きく変化させなくても、リターン流路１００からの空気と合流した外部の空気を所望の温度に制御し易くなる。 In such an operation, in the air conditioner 1 of the present embodiment, a part of the air that has passed through the cooling unit 2 and the heating unit 4 is heated on the upstream side of the cooling unit 2 by the return flow channel 100. The air can be supplied to the position on the upstream side of the portion 4 and merged with the air before being taken into the air intake port 31 of the air passage 30. As a result, even if the temperature of the external air taken into the air intake port 31 greatly fluctuates in accordance with a significant change in the environmental temperature, the external air is not supplied from the temperature-controlled return flow path 100. By merging with air, the temperature approaches the temperature to be temperature controlled. That is, an effect mitigating effect against the influence of environmental fluctuations is produced. Therefore, it becomes easy to control the external air joined with the air from the return flow path 100 to a desired temperature without abruptly changing the refrigeration capacity or the heating capacity in response to a large fluctuation in the temperature of the external air. .
　以上に説明した本実施の形態の空気調和装置１によれば、接続されたダクトを温度制御対象空間まで延ばす際にダクトの屈曲部分を極力抑制できるダクト接続穴を、上方に開口する第１ダクト接続穴９１及びこれとは異なる方向に開口する第２ダクト接続穴９２，９３，９４の中から温度制御対象空間の位置に応じて適宜選択することが可能となる。これにより、ダクトに形成される不所望な屈曲部分による圧損の増加を抑制できることで、送風機の運転効率の低下を抑制できる。また、複数の温度制御対象空間がある場合には、複数のダクト接続穴９１，９２，９３，９４から選択して接続したダクトを対応する温度制御対象空間まで延ばすことにより、ダクトの増加を抑制しつつ複数の温度制御対象空間に温度制御された空気を供給できる。したがって、温度制御対象空間へ空気を供給するためのダクトを種々のパターンで接続することができ、状況に応じて好適なダクトの配置パターンを柔軟に設定することができる。 According to the air conditioning apparatus 1 of the present embodiment described above, the first duct that opens upward the duct connection hole that can suppress the bent portion of the duct as much as possible when extending the connected duct to the temperature control target space. The connection hole 91 and the second duct connection holes 92, 93, 94 that open in a direction different from the connection hole 91 can be appropriately selected according to the position of the temperature control target space. Thereby, the fall of the operating efficiency of an air blower can be suppressed because the increase in the pressure loss by the undesirable bending part formed in a duct can be suppressed. Further, when there are a plurality of temperature control target spaces, an increase in the number of ducts is suppressed by extending the ducts selected and connected from the plurality of duct connection holes 91, 92, 93, 94 to the corresponding temperature control target spaces. However, temperature-controlled air can be supplied to a plurality of temperature control target spaces. Therefore, ducts for supplying air to the temperature control target space can be connected in various patterns, and a suitable duct arrangement pattern can be flexibly set according to the situation.
　また、分配ボックス８０に複数の第１ダクト接続穴９１が設けられていることで、ダクトを通して直接的に空気を供給できる温度制御対象空間を増加させることができるため、利便性を向上させることができる。 Further, since the plurality of first duct connection holes 91 are provided in the distribution box 80, it is possible to increase the temperature control target space in which air can be directly supplied through the duct, so that convenience can be improved. it can.
　また、複数の第１ダクト接続穴９１のうちの少なくとも一つ（一部）の第１ダクト接続穴９１の開口面積が、他の第１ダクト接続穴９１の開口面積と異なっている。これにより、ダクトの占有領域を小さくすることが求められる場合には、開口面積の小さい第１ダクト接続穴９１に細いダクトを接続することにより、占有面積抑制の要求に対応することができ、温度制御対象空間に求められる要求風量が大きい場合には、開口面積の大きい第１ダクト接続穴９１に太いダクトを接続することにより、圧損による送風機の不所望な出力増加を抑制しつつ温度制御対象空間に空気を供給できる。これにより、状況に応じて好適なダクトの配置パターンをより柔軟に設定することができ、利便性を向上させることができる。 Further, the opening area of at least one (part) of the first duct connection holes 91 among the plurality of first duct connection holes 91 is different from the opening area of the other first duct connection holes 91. Thereby, when it is required to reduce the occupied area of the duct, it is possible to meet the demand for suppressing the occupied area by connecting a thin duct to the first duct connecting hole 91 having a small opening area. When the required air volume required for the control target space is large, a thick duct is connected to the first duct connection hole 91 having a large opening area, thereby suppressing an undesired increase in the output of the blower due to pressure loss and the temperature control target space. Can supply air. Thereby, the arrangement pattern of a suitable duct can be set more flexibly according to a situation, and the convenience can be improved.
　また、分配ボックス８０に複数の第２ダクト接続穴９２，９３，９４が設けられていることで、上述と同様に、ダクトを通して直接的に空気を供給できる温度制御対象空間を増加させることができるため、利便性を向上させることができる。 In addition, since the plurality of second duct connection holes 92, 93, 94 are provided in the distribution box 80, the temperature control target space in which air can be directly supplied through the duct can be increased as described above. Therefore, convenience can be improved.
　また、複数の第２ダクト接続穴９２，９３，９４のうちの少なくとも一つ（一部）の第２ダクト接続穴が、他の第２ダクト接続穴とは異なる方向に開口している。これにより、例えば、互いに異なる方向に開口する複数の第２ダクト接続穴９２，９３，９４の中から、接続されたダクトを温度制御対象空間まで延ばす際にダクトの長さを極力抑制できるダクト接続穴を、温度制御対象空間の位置に応じて適宜選択することが可能となる。これにより、状況に応じて好適なダクトの配置パターンをより柔軟に設定することができ、利便性を向上させることができる。 Also, at least one (part) of the plurality of second duct connection holes 92, 93, 94 is opened in a direction different from that of the other second duct connection holes. Thereby, for example, the duct connection that can suppress the length of the duct as much as possible when extending the connected duct to the temperature control target space from among the plurality of second duct connection holes 92, 93, 94 that open in different directions. The hole can be appropriately selected according to the position of the temperature control target space. Thereby, the arrangement pattern of a suitable duct can be set more flexibly according to a situation, and the convenience can be improved.
　また、異なる方向に開口する例えば、第２ダクト接続穴９２，９３の開口面積が、互いに異なっていることによっても、ダクトの接続の向きに加えて、ダクトの径も選択できるため、状況に応じて好適なダクトの配置パターンをより柔軟に設定することができ、利便性を向上させることができる。また、複数の第２ダクト接続穴９２，９３，９４には、同一の方向に開口する少なくとも二つの第２ダクト接続穴が含まれる。これによっても、ダクトを接続するために選択可能なダクト接続穴が増えるため、状況に応じて好適なダクトの配置パターンをより柔軟に設定することができ、利便性を向上させることができる。 Further, for example, since the opening areas of the second duct connection holes 92 and 93 that are opened in different directions are different from each other, in addition to the direction of connection of the duct, the diameter of the duct can be selected. Therefore, it is possible to set a more preferable duct arrangement pattern more flexibly and improve convenience. The plurality of second duct connection holes 92, 93, 94 include at least two second duct connection holes that open in the same direction. This also increases the number of duct connection holes that can be selected to connect the ducts, so that a suitable arrangement pattern of the ducts can be set flexibly according to the situation, and convenience can be improved.
　また、複数の第２ダクト接続穴９２，９３，９４のうちの第２ダクト接続穴９４が、平面視で、空気取込口３１側に開口する。そして、第２ダクト接続穴９４と、フィルタ装置３１３の下流側で且つ空気取込口３１の上流側の部分とが、リターン流路１００によって接続されている。この構成によれば、第２ダクト接続穴９２，９３，９４の一部をリターン流路１００の接続部分として利用でき、空気取込口３１側に開口する第２ダクト接続穴９４に接続したリターン流路１００を空気取込口３１側に延ばすことにより空気を戻して温度制御の安定性の向上を図ることができる。この際に、リターン流路１００の長さを抑制することができ、且つスムーズに空気を戻すことができる。 Also, the second duct connection hole 94 among the plurality of second duct connection holes 92, 93, 94 opens to the air intake port 31 side in a plan view. The second duct connection hole 94 is connected to the downstream side of the filter device 313 and the upstream side of the air intake port 31 by the return flow path 100. According to this configuration, a part of the second duct connection holes 92, 93, 94 can be used as a connection portion of the return flow path 100, and the return connected to the second duct connection hole 94 opened to the air intake port 31 side. By extending the flow path 100 to the air intake port 31 side, air can be returned to improve the stability of temperature control. At this time, the length of the return channel 100 can be suppressed, and air can be returned smoothly.
　また、分配ボックス８０には、第１ダクト接続穴９１及び第２ダクト接続穴９２，９３，９４を閉鎖する閉鎖部材１３０を着脱可能に取り付けるための取付構造ＡＳが設けられている。これにより、使用しない第１ダクト接続穴９１及び第２ダクト接続穴９２，９３，９４からの空気の吐出を防止しつつ温度制御対象空間のみに空気を供給できるようになり、温度制御対象空間に効率的に空気を供給することができる。しかも、取付構造ＡＳは、閉鎖部材１３０又はダクトを選択的に取付可能となっているため、構成の煩雑化を抑制しつつ利便性を向上できる。 Also, the distribution box 80 is provided with an attachment structure AS for detachably attaching a closing member 130 for closing the first duct connection hole 91 and the second duct connection holes 92, 93, 94. As a result, air can be supplied only to the temperature control target space while preventing air from being discharged from the first duct connection hole 91 and the second duct connection holes 92, 93, 94 that are not used. Air can be supplied efficiently. Moreover, since the attachment structure AS can selectively attach the closing member 130 or the duct, it is possible to improve convenience while suppressing complication of the configuration.

In FIG. 6, the air conditioner 1 is disposed in a space F1 below the space F2 in which a temperature control target space (specifically, the semiconductor manufacturing facility S) is disposed.

By connecting the ducts, it is possible to set a duct arrangement pattern that extends the ducts to a desired temperature control target space while suppressing the bent portions of the connected ducts as much as possible. Further, by using the plurality of first duct connection holes 91, it is possible to supply temperature-controlled air to the plurality of temperature control target spaces while suppressing an increase in the number of ducts.
