Several indoor units 16a, 16a,... Can be connected to 16b. The air conditioner 16 is configured as a high sensible heat type multi air conditioner by connecting several indoor units 16a, 16a... To one outdoor unit 16b.

前記天井部11cから吊り下げられた各室内機16a,16a…は、前記通路空間14,14に沿って列をなすようにして、その通路空間14,14毎に複数台配設されている。また、これら各室内機16a,16a…と前記ラック列L1〜L4とは構造的に分離して設置されており、各室内機16a,16a…と各ラック列L1〜L4の間は開放空間となっている。   A plurality of indoor units 16a, 16a,... Suspended from the ceiling portion 11c are arranged for each of the passage spaces 14 and 14 so as to form a row along the passage spaces 14 and 14. These indoor units 16a, 16a ... and the rack rows L1 to L4 are structurally separated, and an open space is provided between each indoor unit 16a, 16a ... and each rack row L1 to L4. It has become.

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,...

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。   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. 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. .
