Description
この発明は、熱交換型換気装置に関するものである。 The present invention relates to a heat exchange type ventilator.
最近は、住まいの高気密・高断熱化や冷暖房機器の性能が向上したことによって、窓を閉め切った生活時間帯が長くなってきている。そこで問題となるのが、自然換気による不安定な換気の問題であり、給気・換気不足による室内の加湿状態と空気汚染、そして窓を開けて換気をすると室温を逃がすことによるエネルギーの損失の問題、また、外気に含まれる花粉や粉塵の侵入、といった数々の問題が生じてきている。 Recently, due to high airtightness and high thermal insulation of houses and improved performance of air-conditioning equipment, living hours with windows closed have become longer. Therefore, the problem of unstable ventilation due to natural ventilation is the problem of indoor humidification and air pollution due to insufficient air supply and ventilation, and the loss of energy due to the release of room temperature when ventilated by opening windows. Numerous problems have arisen, such as the invasion of pollen and dust contained in the outside air.
そこで、近時これらの問題点を解消するものとして全熱交換器を採用した換気システムが開発され多方面に採用されてきている。 Therefore, recently, a ventilation system that employs a total heat exchanger has been developed and has been adopted in many fields as a solution to these problems.
熱交換器を内蔵した換気装置としてはこれまでに種々のものが開発され考案されており、多くのタイプのものが実用化されている。例えば実開平3ー48643号や特開平5ー223306号公報に記載のものもその一つである。 Various ventilators with built-in heat exchangers have been developed and devised so far, and many types have been put to practical use. For example, those described in Japanese Utility Model Laid-Open No. 3-48643 and Japanese Patent Laid-Open No. 5-223306 are one of them.
実開平3ー48643号の構成は、排気用送風機と吸気用送風機とを運転することにより、室内空気内側吸い込み口から箱体内に吸い込まれ、排気通路内の熱交換機を通り室外側吹出から吹き出され室外に排出される。一方室外空気は室外側吸い込み口から箱体内に吸い込まれ、給気通路内の熱交換器を通り、室内側の吹出口から吹き出され室内に吹き出
され室内に給気される。この時、熱交換器では排気流と給気流との間で熱交換が行われ、排気熱を回収して冷暖房負荷を軽減する。この構成の場合、排気用と給気用の送風機の羽根ケーシングに排気、給気通路の一部が一体に形成されているが、その流路に凹凸があって、この部分で乱流が発生し、この乱流が圧損となり送風能力が減少するという問題があった。このような問題点を解決するために、前記特開平5ー223306号では給気通路と排気通路の一部を一体に設けたケーシングと、前記の両者を分離するセパレータに給気流、排気流の案内板を一体に形成したことで解決しようとしている。
The configuration of Japanese Utility Model Laid-Open No. 3-48643 is operated by operating the exhaust fan and the intake fan, and is sucked into the box from the indoor air inner suction port, and blown out from the outdoor outlet through the heat exchanger in the exhaust passage. It is discharged outside the room. On the other hand, the outdoor air is sucked into the box from the outdoor suction port, passes through the heat exchanger in the air supply passage, is blown out from the air outlet on the indoor side, is blown into the room, and is supplied into the room. At this time, in the heat exchanger, heat exchange is performed between the exhaust flow and the supply air flow, and the exhaust heat is recovered to reduce the cooling / heating load. In this configuration, the exhaust and supply passages are partly formed integrally in the blade casings of the exhaust and supply fans, but there are irregularities in the flow path, and turbulence occurs in this part. However, there is a problem that this turbulent flow causes pressure loss and air blowing capacity decreases. In order to solve such problems, in Japanese Patent Application Laid-Open No. 5-223306, a casing in which a part of an air supply passage and an exhaust passage are provided integrally, and a separator that separates both the air supply and exhaust flows are provided. We are trying to solve this problem by forming the guide plate in one piece.
しかしながら、前記の従来技術は構造が比較的複雑である為に組立が面倒であると共に、この複雑さの故に効率的な空気流が得られない場合が生じていた。効率的な換気がおこなわれないということは、各部屋へ新鮮な空気の供給と安定した換気の確保ができないということであり、室内温度の維持ができないことでもある。 However, the above-described prior art has a troublesome assembly because the structure is relatively complicated, and there is a case where an efficient air flow cannot be obtained due to this complexity. The fact that efficient ventilation is not performed means that fresh air cannot be supplied to each room and stable ventilation cannot be ensured, and the room temperature cannot be maintained.
従って、本発明の主たる目的は従来技術の種々の欠陥を改善した新規で構造簡単な熱交換型換気装置を提供するものである。 Accordingly, the main object of the present invention is to provide a new and simple heat exchange type ventilator which has improved various deficiencies of the prior art.

To prevent this, the entire building is ventilated by being discharged outside.
以下、本発明を実施するための形態の実施例に基づいて説明する。 Hereinafter, the present invention will be described based on examples of the mode for carrying out the present invention.
この発明の好ましい実施例を示す図1、図2及び図3において、箱型のケーシング11の中には、モータ12の回転軸の一方に結合された第1の送風機13と、他方の回転軸に取り付いた第2の送風機14とをケーシング11のほぼ中心位置に、所望の取り付け壁部(図3参照)を介して取り付いている。前記第1及び第2の送風機13,14はいずれも同一金型で形成したシロッコファンであり、モータ15の同軸に且つ同一回転方向となるように、しかも同じ向きに配列されており、組立の際に誤って向きが違って取り付く心配がないようになっている。前記モータ11及び2個の送風機13,14の取り付け位置の近傍には、断面矩形で細長い箱型の熱交換器15が設置されている。 1, 2 and 3 showing a preferred embodiment of the present invention, a box-shaped casing 11 includes a first blower 13 coupled to one of the rotating shafts of a motor 12 and the other rotating shaft. The second blower 14 attached to is attached to a substantially central position of the casing 11 via a desired mounting wall (see FIG. 3). The first and second blowers 13 and 14 are both sirocco fans formed of the same mold, and are arranged in the same direction so as to be coaxial with the motor 15 and in the same rotational direction. There is no need to worry about accidentally mounting it in the wrong direction. In the vicinity of the mounting position of the motor 11 and the two blowers 13 and 14, a box-shaped heat exchanger 15 having a rectangular cross section is installed.
前記熱交換器15は全熱交換型で直交流透過方式のものであり、板状の熱交換素子を互い違いに配列して積層させて構成したものである。熱交換器15を通る室内の汚れた空気(RA)は、前記外気が通る熱交換器の通路に対して直交する通路を通って熱交換され、第2の送風機14によって前記排気口21から室外へと排出されるようにしてなるものである。図3において、熱交換器15は外気吸入口20に面した側と、還気口23に面した側にはそれぞれフィルタ25,26が取り付いている。図3において、熱交換器15はほぼ正方形の断面形状を有しており、α=20度となる角度にやや傾けて取り付けられている。これは、幾つかの空気流れが存在する中で、それぞれの空気の流れの損失抵抗をできるだけ少なくする目的で成されている。 The heat exchanger 15 is of a total heat exchange type and of a cross flow transmission type, and is configured by laminating and laminating plate-like heat exchange elements. Dirty air (RA) in the room passing through the heat exchanger 15 is heat-exchanged through a passage orthogonal to the passage of the heat exchanger through which the outside air passes. It is designed to be discharged into the water. In FIG. 3, the heat exchanger 15 has filters 25 and 26 attached to the side facing the outside air inlet 20 and the side facing the return air port 23, respectively. In FIG. 3, the heat exchanger 15 has a substantially square cross-sectional shape, and is attached with a slight inclination to an angle of α = 20 degrees. This is done in order to minimize the loss resistance of each air flow in the presence of several air flows.
前記箱型のケーシング11の一方の側には、外気を吸入する為の外気吸入口20と、その近傍に排気口21とが並設されている。前記外気吸入口20には、花粉や排ガス等も多分に含んでいると思われる屋外の空気(OA)が入り込むための口である。そして、前記排気口21からは、後述する換気装置のフロントパネル22の換気口23から入り込んだ室内の汚れた空気(RA)が換気装置本体10の熱交換器15を通って熱交換されて室外に排出される。 On one side of the box-shaped casing 11, an outside air inlet 20 for sucking outside air and an exhaust port 21 in the vicinity thereof are arranged in parallel. The outside air inlet 20 is an opening through which outdoor air (OA) that seems to contain a lot of pollen, exhaust gas, etc. enters. From the exhaust port 21, dirty air (RA) in the room that has entered through a vent port 23 of the front panel 22 of the ventilator, which will be described later, is heat-exchanged through the heat exchanger 15 of the ventilator main body 10, and is thus outdoor. To be discharged.
ここで、外気吸入口20から吸い込まれた外気(OA)は前記のように熱交換器15を通り、そのまま第1の送風機13の中を通り、この第1の送風機13によって第2の送風機14との間の空間、即ち前記モータ12に触れてモータを冷却しながら、室内給気口24に送り込まれ、そこから室内に供給される。従って、本発明の換気装置はモータ冷却効果を呈する構造ともなっている。 Here, the outside air (OA) sucked from the outside air inlet 20 passes through the heat exchanger 15 as described above, passes through the first blower 13 as it is, and the second blower 14 is passed by the first blower 13. The air is fed into the indoor air supply port 24 while being cooled by touching the motor 12, that is, the motor 12, and is supplied to the room from there. Therefore, the ventilator of the present invention has a structure that exhibits a motor cooling effect.
また、室内の汚れた空気(RA)は、熱交換器15の別側から入り込んで第2の送風機14へと送り込まれ、この第2の送風機14によって排気口21から室外に排出される。このとき室内の汚れた空気は熱交換器15を経ないで直接排気口21に送られる。 The dirty air (RA) in the room enters from the other side of the heat exchanger 15 and is sent to the second blower 14, and is discharged from the exhaust port 21 to the outside by the second blower 14. At this time, the dirty air in the room is sent directly to the exhaust port 21 without passing through the heat exchanger 15.
ケーシング11の対向する他側には複数の(図示例では4個)の給気口24が配設されている。この給気口24は前記外気吸入口20からの外気(OA)を熱交換器15や第1の送風機13を介して換気装置本体10から外側へ、即ち換気しようとする居住室内に送り込む吹出し口である。従って、ここでは室内給気口24と称する。この室内給気口24から吹き出された空気(SA)は室内を循環して前記還気口23と熱交換器15と第2の送風機14を通って排気口21から排気(EA)として住居の外部へと排出される。 A plurality (four in the illustrated example) of air supply ports 24 are disposed on the opposite side of the casing 11. The air supply port 24 is a blowout port for sending outside air (OA) from the outside air intake port 20 to the outside from the ventilator body 10 through the heat exchanger 15 and the first blower 13, that is, into the living room to be ventilated. It is. Therefore, it is called the indoor air supply port 24 here. The air (SA) blown out from the indoor air supply port 24 circulates in the room, passes through the return air port 23, the heat exchanger 15, and the second blower 14, and is exhausted from the exhaust port 21 as exhaust (EA). It is discharged outside.
図4は前記の全熱交換型換気装置10を家屋内にシステムとして取り付けた状態を例示したものである。図示のシステムでは家屋の1階部分と2階部分とに分けてそれぞれに配管をしている。このように1階部分と2階部分とに分けて2台の熱交換装置を設け、各階の天井裏に全熱交換換気装置を設置するワンフローア完結型とすると、各階を繋ぐダクトスペースが不要となり、工事が簡単であるし経済的でもある。しかし、必要に応じて、或いは熱交換装置自体の能力によって1台の熱交換装置のみとすることも可能であるし、3台以上のシステムとすることも可能であること勿論である。また、図示を省略したが、タイマー装置を内臓させてオン・オフの自動切り替えをできるようにすることも可能であるし、リモートコントロラのシステムを取り付けることもできる。 FIG. 4 illustrates a state in which the total heat exchange type ventilator 10 is installed as a system in a house. In the illustrated system, piping is divided into a first floor portion and a second floor portion of the house. In this way, two heat exchange devices are provided separately for the first floor part and the second floor part, and if it is a one-floor complete type with a total heat exchange ventilator installed on the back of the ceiling of each floor, a duct space connecting each floor becomes unnecessary. The construction is simple and economical. However, as a matter of necessity or according to the capability of the heat exchange device itself, it is possible to have only one heat exchange device, and it is of course possible to have three or more systems. Although not shown in the figure, it is possible to incorporate a timer device so as to enable automatic switching between on and off, or a remote controller system can be attached.
図5は箱型ケーシング11の好ましい構成を示す斜視図である。この図において、箱型ケーシング11は、取り付け場所である例えば天井に最初にそのまま設置される取り付け枠体31と、熱交換器15やや送風機13、14等の内部機器を収納・保持した保持枠体41とを有している。このうち、天井などに取り付けられる取り付け枠体は図示の通り、外気吸入口20と排出口21、および室内給気口24をそれぞれの側壁に予め形成されており、その側壁下部には爪を形成した弾性係止具32,33が形成されている。つぎに、前記取り付け枠体31に前記弾性係止具32,33を介して脱着自在に取り付けられる前記保持枠体41は、前記した種々の空気の流れを形成できるような構造を有し、且つ予め内部装置であるモータ12、送風機13,14、そして熱交換器15が搭載されている。このように形成された保持枠体41を、予め取り付け場所に取り付けた取り付け枠体31に下側から挿入して前記弾性係止具32,33の爪が係止凹所32,33にそれぞれ弾性嵌合するようにして保持枠体41を取り付け枠体31内に保持する。このような構成とすることにより、ダクト接続部の工事を先に完了させてから保持枠体41を含む本体を下から差し込むようにして簡単に取り付けられ、しかも、工事が別々の場所で行うことが出来るため、最近のように狭い天井の家屋構造の場合にも簡単に工事が可能となるし、本体が簡単に取り外せるので保守点検が容易に成し得ることとなるので極めて有利である。 FIG. 5 is a perspective view showing a preferred configuration of the box-shaped casing 11. In this figure, a box-shaped casing 11 includes a mounting frame 31 that is first installed on the ceiling, which is a mounting location, and a holding frame that stores and holds internal devices such as the heat exchanger 15 and the fans 13 and 14. 41. Among them, as shown in the figure, the attachment frame body attached to the ceiling or the like has the outside air inlet 20, the outlet 21, and the indoor air inlet 24 formed in advance on the respective side walls, and a nail is formed in the lower part of the side walls. The elastic locking tools 32 and 33 are formed. Next, the holding frame body 41 detachably attached to the attachment frame body 31 via the elastic locking members 32 and 33 has a structure capable of forming the various air flows described above, and The motor 12, the blowers 13 and 14, and the heat exchanger 15 which are internal devices are mounted in advance. The holding frame body 41 formed in this way is inserted into the mounting frame body 31 attached in advance to the mounting location from the lower side, and the claws of the elastic locking devices 32 and 33 are elastically moved into the locking recesses 32 and 33, respectively. The holding frame body 41 is held in the attachment frame body 31 so as to be fitted. By adopting such a configuration, after the construction of the duct connecting portion is completed first, the main body including the holding frame body 41 can be easily attached by being inserted from the bottom, and the construction can be performed in different places. Therefore, construction can be easily performed even in the case of a house structure with a narrow ceiling as in recent times, and since the main body can be easily removed, maintenance and inspection can be easily performed, which is extremely advantageous.
図6は着脱自在とした熱交換器15の取り付け(取り外し)を図示したものである。図示の通り熱交換器15は把持部45と設けた枠体46に一体に取り付いており、図5に示した保持枠体41の所定位置に設けた弾性保持具(図示せず)を介して脱着自在に保持される(図3参照)。かくて、熱交換器のみの保守点検が極めて簡単にできる。 FIG. 6 illustrates the attachment (removal) of the heat exchanger 15 that is detachable. As shown in the figure, the heat exchanger 15 is integrally attached to the holding body 45 and the frame 46 provided, and via an elastic holder (not shown) provided at a predetermined position of the holding frame 41 shown in FIG. Removably held (see FIG. 3). Thus, maintenance and inspection of only the heat exchanger can be performed very easily.
本発明は構造簡単で経済的であり、設置・保守・点検が容易な熱交換型換気装置に利用できる。 The present invention is simple in structure and economical, and can be used for a heat exchange type ventilator that is easy to install, maintain, and inspect.
