も大幅な改造が必要となる。In other words, as shown in Fig. 3, the conventional air conditioning system for computer rooms has a double structure with a raised floor 12, and a computer room 1a on the floor in the room 10 that takes in room air, and an air intake under the floor. An electronic computer 11b is disposed therein, and the ceiling is a plenum chamber 13. Then, air is supplied from between the raised floor] 2 in the direction of the arrow in the figure, from the air outlet 14 through the room to the computer 11a, and directly from the air outlet 14 to the computer 11a, and directly from the air outlet 14 to the computer 11a, and from the air outlet 14 directly to the computer 11a, through the air inlet 15 provided in the ceiling, The structure is such that the air flows from the inside of the plenum chamber 13 and is returned. (Refer to Air Conditioning and Sanitation Engineering Handbook Vol. The method is very different from the arrangement of ventilation and air conditioning equipment in ordinary rooms. Therefore, when adding new large electrical equipment to a room in an existing plant, not only the installation work of the electrical equipment but also the ventilation equipment needs to be significantly modified.

The cooling air sucked in from the air intake port of the electrical equipment housing is discharged from the air outlet and then guided to the vicinity of the indoor air conditioning system exhaust port through the connecting ducts 1 to 1, so that high-temperature air is diffused indoors. The air is sucked into the air conditioning system exhaust port without being absorbed.
（実施例） 本発明の実施例を図面を参照して説明する。(Example) Embodiments of the present invention will be described with reference to the drawings.

ファンである。FIG. 1 is a perspective view of one embodiment of the present invention. As shown in the figure, a housing 1 housing a large air-cooled electronic computer (not shown) has a plurality of Air intake port 2
is opened. Furthermore, a plurality of air outlets 3 are opened on the upper surface of the housing 1 . A connecting duct 4 made of transparent acrylic is attached to the top surface of the housing 1, covering all of these air outlet ports 3 and extending to the vicinity of an indoor exhaust port 9, which will be described later. Note that 5 is a cooling fan for forcibly cooling the inside of the cylinder.

の１−１線に沿う断面図である。Figure 2 (a) is a plan view of the computer room in which the housing 1 with the above-mentioned connecting duct is installed, and Figure 2 (b) is the same figure (a).
FIG. 2 is a sectional view taken along line 1-1 of FIG.

製作されたものではない。As shown in FIG. 2, a plurality of rows of cabinets 1 housing electronic computers are arranged in a computer room 6, and indoor lighting fixtures 7 are installed between the cabinets and on the ceiling outside the cabinets. There is. Inside the computer room 6, an air supply port 8 and an air exhaust port 9 of air conditioning equipment are installed. The air supply port 8 and the exhaust port 9 of this air conditioning equipment are ordinary ones and are not specially manufactured for use in a computer room.

空気は空調系排気口９より効率よく室外に排気される。Since the present embodiment is configured as described above, the air blown into the computer room 6 from the air conditioning system air supply port 8 is sucked through the suction port 2 of the computer case 1, and the air inside the computer case 1 is The inside of the housing 1 is cooled by the cooling fan 5, and the pressure is increased, and when it is exhausted from the air outlet 3, it becomes high temperature air. It is then opened and discharged outside from the air conditioning system exhaust port 9. In this way, the exhaust air inside the computer room is efficiently exhausted outside through the air conditioning system exhaust port 9.

々独立していて空調系排気口９と直接接続されていない
ため空調系のファン容量と電子計算機群の排気ファン容
量がマツチングしていない場合でも用いることができる
。In addition, since the connecting ducts 4 installed in the computer room are each independent and are not directly connected to the air conditioning system exhaust port 9, the fan capacity of the air conditioning system and the exhaust fan capacity of the computer group may not match. It can also be used.

の容量はこれ以上あるため、連結ダクトを空調排気口に
連結すると、空調／計算機のファン能力の関係からファ
ンの故障、室内の過負圧等の問題が生じる。In other words, in general, when adding a casing housing electrical equipment, the capacity of the casing is greater than this compared to the amount of air sent and exhausted by the air conditioning system, so if you connect the connecting duct to the air conditioning exhaust port, Problems such as fan failure and over-negative pressure in the room arise due to the relationship between the fan capacity of the air conditioner and the computer.
一方、連結ダク１〜を空調排気口の近傍で開放した場合
は、空調側で吸引しきれない量は室内に開放されるだけ
なので、上記問題が生じない。On the other hand, when the connecting ducts 1 to 1 are opened in the vicinity of the air conditioning exhaust port, the above problem does not occur because the amount that cannot be suctioned by the air conditioning side is only released into the room.
なお、空調側で吸引しきれなかった筐体の排気は結局、

からは大幅な改善となる。In addition, the exhaust air from the housing that could not be sucked in by the air conditioner ended up being
Although this will raise the indoor temperature by 1,000 yen, the distance from the air intake ports of the computer group causes high-temperature air to diffuse and mix with air supplied to the air conditioning system into the room. As a result, the temperature decreases, resulting in a significant improvement from the standpoint of cooling the electronic H1 computer group.
本実施例によると、以下のような効果がある。According to this embodiment, the following effects are achieved.
（１）電子計算機から排気される高温空気が、空調系排
気口９近傍まで、室内空気と隔離されているため、排気
空気による室内の高温及び排気空気が直接吸込口２に流

。(1) The high temperature air exhausted from the computer is isolated from the indoor air up to the vicinity of the air conditioning system exhaust port 9, so the high temperature indoors due to the exhaust air and the exhaust air directly flow into the suction port 2 (short circuit ) can be prevented.
■ 電子計算機の発生騒音としては、主として冷却ファ
ン５の運転によるものが空気吹出口３を通して聞こえる
が、連結ダクト４を設けているので筐体１の盤近傍では
遮音効果がある。■ The noise generated by the computer is mainly caused by the operation of the cooling fan 5 and can be heard through the air outlet 3, but since the connecting duct 4 is provided, there is a sound insulation effect near the panel of the casing 1.

付属品が不要であるので、構造がコンパクトとなり、電
子計算機筐体の許容積載荷重条件を満足する。(3) Since the connecting duct 4 is made of transparent acrylic, it is lightweight, and there is no need for accessories such as a support device to support the connecting duct 4 to 4 itself, so the structure is compact and can fit within the computer case. Satisfy live load conditions.
Ｇ）連結ダク１〜４が透明アクリル製のため、室内の照
明を遮ぎることかなく、連結ダクト４を用いたことによ
る室内照度の低下がない。G) Since the connecting ducts 1 to 4 are made of transparent acrylic, they do not block the indoor illumination, and there is no reduction in indoor illuminance due to the use of the connecting duct 4.
■ 連結ダクト４は各々が独立しており、空調系排気口
９と直接接続していないので、空調系と電子計算機側の
排気ファン容量がマツチングしなくても用いることがで
きる。(2) Since the connecting ducts 4 are each independent and are not directly connected to the air conditioning system exhaust port 9, they can be used even if the exhaust fan capacities of the air conditioning system and the computer side do not match.
以上説明したように、本発明によれば、電子計算機、サ
イリスク盤等の空気冷却式電気機器の増設に対し空調系
の大幅な変更をしなくても対処できる。As described above, according to the present invention, it is possible to cope with the addition of air-cooled electrical equipment such as electronic computers and silice panels without making major changes to the air conditioning system.
