　なお、前記各室内機１６ａ，１６ａ…は、前記ラック１３の前面に有するラック吸い込み面１３ａに対向している傾斜パネル面に冷気吹き出し口１９を有し、４つの側面に前記機器室１１の上部空間における高温空気を取り入れる吸気口２０を各々有してなる箱形をした筐体２１を備え、該箱形筐体２１内に上記熱交換器２０ａと送風機２２を配設している。 Each of the indoor units 16a, 16a,... Has a cold air outlet 19 on the inclined panel surface facing the rack suction surface 13a on the front surface of the rack 13, and has an upper portion of the equipment room 11 on four side surfaces. A box-shaped casing 21 having air inlets 20 for taking in high-temperature air in the space is provided, and the heat exchanger 20 a and the blower 22 are arranged in the box-shaped casing 21.
　また、前記各室内機１６ａ，１６ａ…は、図３あるいは図４に示すように該各室内機１６ａ，１６ａ同士の側面に設けた熱交換器２０ａがそれぞれ正対向しないように、該各熱交換器２０ａ，２０ａ…を各々平面視所定角度回転させて設けている。こうすることにより、該各室内機１６ａ，１６ａ…における熱交換器２０ａ，２０ａ…は、４つ全ての口が常に開放された状態におかれて、前記機器室１１の上部空間における高温空気を該各室内機における熱交換器２０ａ，２０ａ…へスムーズに取り入れることができるようになっている。 Further, as shown in FIG. 3 or FIG. 4, each of the indoor units 16a, 16a... Has a heat exchange so that the heat exchangers 20a provided on the side surfaces of the indoor units 16a, 16a do not face each other. .. Are rotated by a predetermined angle in plan view. In this way, the heat exchangers 20a, 20a, ... in the indoor units 16a, 16a, ... are placed in a state in which all four ports are always open, and the high temperature air in the upper space of the equipment room 11 is discharged. The indoor units can be smoothly taken into the heat exchangers 20a, 20a.
　なお、前記各室内機１６ａ，１６…の設置は、この構造に限られることなく、色々なバリエーションが可能であり、例えば図５あるいは図６に示すような構成も可能である。すなわち、図５あるいは図６に示す構成は、各熱交換器２０ａ，２０ａ…を各々平面視所定角度回転させて設けた各室内機１６ａ，１６ａ…の整列設置の方法について、該各室内機１６ａ，１６ａ，…の間に空間を設けている。 It should be noted that the installation of the indoor units 16a, 16... Is not limited to this structure, and various variations are possible. For example, a configuration as shown in FIG. That is, in the configuration shown in FIG. 5 or FIG. 6, the indoor units 16a, 16a,... Are arranged in an aligned manner by rotating the heat exchangers 20a, 20a,. , 16a,...
　次に、このように構成された空調システムの動作を説明する。前記エアコン１６が駆動されると前記送風機２２が回転し、内部冷却コイルで冷却処理された冷気が該送風機２２で生起される風に乗り、前記冷気吹き出し口１９を通って前記ラック１３の前面に有するラック吸い込み面１３ａに向けて吹き出す。該ラック吸い込み面１３ａに向けて吹き出された冷気は、前記ラック１３内を通って前記通路空間１５側に向かって流れ、このとき該ラック１３内の前記電子機器１２の熱を奪って該電子機器１２を冷却する。 Next, the operation of the air conditioning system configured as described above will be described. When the air conditioner 16 is driven, the blower 22 rotates, and the cool air cooled by the internal cooling coil rides on the wind generated by the blower 22 and passes through the cool air outlet 19 to the front of the rack 13. Blow out toward the rack suction surface 13a. The cold air blown toward the rack suction surface 13a flows toward the passage space 15 through the rack 13, and at this time, the electronic device 12 in the rack 13 is deprived of heat and the electronic device 12 is cooled.
　また、前記電子機器１２の熱を奪って温められ前記通路空間１５に排出された空気は、各室内機１６ａ，１６ａ…の吸気口２０，２０…を通って各室内機１６ａ，１６ａ内に吸い込まれる。そして、該各室内機１６ａ，１６ａ…内の各熱交換器２０ａ，２０ａ…で冷却処理され、その後、前記送風機２２で生起される風に乗せられ、前記冷気吹き出し口１９を通って前記ラック吸い込み面１３ａに向けて再び送り出される。この空気の循環により機器室１１内全体の空調が行われる。 Also, the air that has been deprived of heat from the electronic device 12 and discharged into the passage space 15 is sucked into the indoor units 16a and 16a through the intake ports 20 and 20 of the indoor units 16a and 16a. It is. Then, each of the indoor units 16a, 16a,... Is cooled by the heat exchangers 20a, 20a, and then put on the wind generated by the blower 22, and the rack sucks the air through the cold air outlet 19. It is sent out again toward the surface 13a. The entire inside of the equipment room 11 is air-conditioned by this air circulation.
　なお、本実施の形態例では、各室内機１６ａ，１６…が間前記ラック列Ｌ１とＬ２の各ラック吸い込み面１３ａ、及び前記ラック列Ｌ３とＬ４の各ラック吸い込み面１３ａに吹き出される風量、すなわち前記各通路空間１４に面する前記ラック吸い込み面１３ａに向けて吹き出される送風量は、前記ラック１３内を通って下流側、すなわち前記通路空間１５内に排出される使用済み冷気の排気量よりも大きくなるように設定してある。この調節はコントローラ２３により制御される。 In the present embodiment, the amount of air blown to each rack suction surface 13a of each of the rack rows L1 and L2 and each rack suction surface 13a of the rack rows L3 and L4, That is, the amount of air blown out toward the rack suction surface 13 a facing each passage space 14 is the amount of used cold air discharged through the rack 13 to the downstream side, that is, into the passage space 15. It is set to be larger than. This adjustment is controlled by the controller 23.
　このように、前記各室内機１６ａ，１６ａ…が前記各通路空間１４に面する前記ラック吸い込み面１３ａに向けて吹き出す風量を、ラック１３内を通って下流側から排出される使用済み空気の排気量よりも大きく設定すると、吹き出し側(上流側)が高圧で、吸い込み側が低圧となるため、各室内機１６ａ，１６ａから吹き出された冷気が、ラック１３内を通らずにバイパスして各室内機１６ａ，１６ａ…側に戻る漏れ冷気２４ａ(図１参照)、あるいは使用済みの空気が吸気口２０，２０…へ戻らずにバイパスして吹き出し側の各通路空間１４，１４内漏れ冷気に戻る漏れ冷気２４ｂ(図１参照)を防ぐことができる。このとき、例えば、吹き出し側の各通路空間１４のラック高さから床面までの間にカーテンあるいは開閉扉を設けて、これを閉鎖することにより、バイパス防止の効果を一層高めることができる。 As described above, the exhaust amount of the used air discharged from the downstream side through the rack 13 by using the air volume blown out toward the rack suction surface 13a facing the passage space 14 by the indoor units 16a, 16a. If it is set larger than the amount, the blowout side (upstream side) has a high pressure and the suction side has a low pressure, so that the cold air blown out from each indoor unit 16a, 16a bypasses the inside of the rack 13 and bypasses each indoor unit. Leaked cold air 24a returning to the side 16a, 16a... (See FIG. 1) or used air bypassing back to the intake ports 20, 20,. Cold air 24b (see FIG. 1) can be prevented. At this time, for example, by providing a curtain or an opening / closing door between the rack height of each passage space 14 on the blowing side and the floor surface and closing it, the effect of preventing bypass can be further enhanced.
　したがって、本実施の形態例による空調システムによれば、前記エアコン１６の前記室内機１６ａ，１６ａ…を前記機器室１１の天井部１１ｃに設置しているので、複数台の室内機１６ａ，１６ａ…を該機器室１１内にコンパクトに設置することができ、該機器室の小型化が期待できる。また、床部１１ａを二重構造とせずに、前記機器室１１内だけで冷気の冷却処理を行うことができるので、前記室内機１６ａ…１６ａ…を設置する際の制限を少なくすることができる。 Therefore, according to the air conditioning system according to the present embodiment, the indoor units 16a, 16a... Of the air conditioner 16 are installed on the ceiling portion 11c of the equipment room 11, so that a plurality of indoor units 16a, 16a. Can be installed in the equipment room 11 in a compact manner, and a reduction in the size of the equipment room can be expected. Moreover, since the cooling process of the cold air can be performed only in the equipment room 11 without using the floor portion 11a as a double structure, it is possible to reduce restrictions when installing the indoor units 16a. .
