この発明は病院のクリーンルームなどに設置される空気
調和装置に係り、特に温度制御機能と塵埃除去機能とを
備えたクリーンユニットに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner installed in a clean room of a hospital, and more particularly to a clean unit having a temperature control function and a dust removal function.
従来この種の空気調和装置としては、温度制御の目的の
ために組立られたユニットとクリーンルーム用に組立て
られた塵埃除去の目的のために組立てられたユニットを
一つの部屋に設置して温度と塵埃量とを制御していた。Conventionally, this type of air conditioner has been installed in one room with a unit assembled for the purpose of temperature control and a unit assembled for the purpose of dust removal for clean rooms. The amount was controlled.
温度制御用のユニットは、空気の吸込口から粗塵フィル
タ、送風機および熱交換器の順に配列されており、塵埃
除去用のユニットは空気の吸込口から粗塵フィルタ、送
風機および高性送フィルタの順に配列されていた。The temperature control unit is arranged from the air suction port to the coarse dust filter, blower, and heat exchanger, and the dust removal unit is arranged from the air suction port to the coarse dust filter, blower, and high-performance filter. They were arranged in order.
近年、温度制御用のユニットとクリーンルームの塵埃除
去用のユニットとを一体に組込んだコンパクトな装置が
髪留されるようになった。In recent years, compact devices that integrate a temperature control unit and a clean room dust removal unit have become popular.
しかし、このようなユニットを構成するために、送風機
の吐出側に熱交換器を設置すると、送風機の吐出側空気
の流線の拡散角度は吸込側空気の流線の収縮角度に比し
て小さいので、熱交換器を送風機の吸込側に設置した場
合と同等の熱交換能力を得るためには、送風機と熱交換
器との間隔を長くして、空気を熱交換器の幅方向に一様
に接触させる必要があった。また逆に熱交換器を送風機
の吸込側全面に設置すると、熱交換効率は向上するが熱
交換器で異常高温の空気が発生したとき、送風機□の電
動機が過熱されるおそれがあった。However, when a heat exchanger is installed on the discharge side of the blower to configure such a unit, the diffusion angle of the streamlines of the air on the discharge side of the blower is smaller than the contraction angle of the streamlines of the air on the suction side. Therefore, in order to obtain the same heat exchange capacity as when the heat exchanger is installed on the suction side of the blower, the distance between the blower and the heat exchanger must be increased to distribute the air evenly in the width direction of the heat exchanger. It was necessary to contact. On the other hand, if a heat exchanger is installed all over the suction side of the blower, the heat exchange efficiency will improve, but when abnormally high temperature air is generated in the heat exchanger, there is a risk that the electric motor of the blower □ will overheat.
また送風機と吸込口とを直線で結べるような配置とする
と送風機の音が直接室内へ出るため騒音が発生する欠点
があった。In addition, if the blower and the suction port were arranged so that they could be connected in a straight line, the sound of the blower would go directly into the room, creating noise.
この発明の目的は、温間制御用のユニットと塵埃除去用
のユニットとを一体として、しかも送風機と熱交換器と
の間の距離を短くシ、電動機の過熱°を防止し、騒音の
小さなコンパクトなりリーン・ ユニットを提供するに
ある。The purpose of this invention is to integrate a warm control unit and a dust removal unit into one unit, shorten the distance between the blower and the heat exchanger, prevent the electric motor from overheating, and create a compact, low-noise unit. The aim is to provide a lean unit.

に導き、騒音の錦生を防ぐために、吸込口の上方に付設
したじゃま板により吸込口と送風機との間に於て空気を
迂流させると共に、水平投影面上においては送風機と高
性能フィルタとの間に熱交換器とダン・ξとが介在する
ように配置して、送風機の騒音が直接吸込口に到達しな
いように構成したものである。In order to shorten the length of the unit, this invention arranges the unit's components in the order of the air flow from the suction side, including the coarse dust filter, heat exchanger, blower, and high-performance filter. In order to prevent
A damper for static pressure adjustment is attached to the air passage on the motor side of the blower, and the air is divided into each air passage, then merged and guided to the blower.In order to prevent noise generation, a damper is installed above the air inlet. The air is diverted between the suction port and the blower by the attached baffle plate, and a heat exchanger and a heat exchanger are interposed between the blower and the high-performance filter on the horizontal projection plane. The structure is such that the noise from the blower does not directly reach the suction port.

に固定する。The air passage on the suction side of the blower 8 is divided into two by a baffle plate 10 attached above the suction port 3, and the air entering from the suction port 3 is diverted, and the air on the side where the electric motor 11 of the blower 8 is not installed is divided into two parts. A heat exchanger 12 is installed on the road, and the electric motor 1 of the blower 8
A Danno ξ13 for static pressure is rotatably fixed to the air passage on the first side.

却する。The air sucked in from the room by the blower 8 enters through the suction port 3, and after coarse dust is removed by the coarse dust filter 5,
The air that flows detoured by the baffle plate 10 and then branches and passes through the air passage on the side where the electric motor 11 of the blower 8 is not installed is heated or cooled by the heat exchanger 12 and then sent to the blower 8. The air that has passed through the air passage on the motor 11 side is sent directly to the blower 8, thereby cooling the motor 11.
両側の空気は送風機８内で混合された後、高性能フィル
タ６を通過して、塵埃を除去された後室内へ吹出される
。After the air on both sides is mixed in the blower 8, it passes through the high-performance filter 6 to remove dust and is blown into the room.
室内を清浄に保つために必要な風量は、室内を冷暖房す
るために必要な風量の２倍以上を必要とするので、空気
の一部を熱交換器を通過させなくても、特に熱交換器の
列数を多くする必要はなく、圧力損失は増加しない。The amount of air required to keep the room clean is more than twice the amount of air needed to cool and heat the room, so even if some of the air does not pass through the heat exchanger, There is no need to increase the number of rows, and pressure loss does not increase.
この発明は、熱交換器を送風機の吸込側に設置したから
、送風機と熱交換器との間の距離を短くすることができ

作費も低減され、天井への取付も容易となり、熱交換効
率も向上する。In this invention, since the heat exchanger is installed on the suction side of the blower, the distance between the blower and the heat exchanger can be shortened. Therefore, the unit can be made compact, manufacturing costs are reduced, installation on the ceiling is easy, and heat exchange efficiency is improved.
また空気の一部を直接に送風機の電動機側の風道に導い
て電動機の冷却を行なわせているので、熱交換器におい
て異常高温の空気が発生しても、電動機が過熱されるこ
とはない。In addition, a portion of the air is guided directly to the air passage on the motor side of the blower to cool the motor, so even if abnormally high temperature air is generated in the heat exchanger, the motor will not overheat. .
また送風機より発生する騒音は、じゃま板で遮られて熱
交換器とダンパとを介して吸込口へ達するので、室内の
騒音が少くなる。送風機の音が室内へ直接用るときは床
上１ｍの所で６５ホンであったが、この発明の構造で、
じゃま板を鉄板に厚さ２０ミリメートルのグラスウール

あった。以上の効果を綜合して温度制御機能と塵埃除去
機能とを備えた騒音の少いコンパクトなりリーンユニッ
トを提供することができる。In addition, the noise generated by the blower is blocked by the baffle plate and reaches the suction port via the heat exchanger and damper, thereby reducing indoor noise. When the blower was used directly indoors, the sound was 65 phon at 1 meter above the floor, but with the structure of this invention,
When the baffle plate was made of iron and lined with 20 mm thick glass wool (JIS 32 9/m3), the cost was 50 hon. By combining the above effects, it is possible to provide a compact lean unit with less noise and having a temperature control function and a dust removal function.
