図４は、空気調和機本体の後面側からの一部分解斜視図である。図５は、空気調和機本体の後面側からの部分拡大斜視図である。
空気調和機本体１ａの後面側には、後面パネル６０が設けられている。この後面パネル６０には、設置前には樹脂製の蓋６１Ａが嵌め込まれた配管接続用孔６１、取り外し自在に一部が打ち抜かれたノックアウトパネルとして構成されている外気導入口６２をはじめとして、配線用孔などの各種孔が設けられている。
外気導入口６２の周囲には、ダクト取付用ねじ孔６３が設けられており、必要に応じてダクト配管６４が接続されることとなる。
後面パネル６０と中仕切板４３により仕切られる室は、上述した送風機室１３Ｘを構成しており、送風機室１３Ｘ内には、上述した電装箱１１、送風機１３が配置されている。FIG. 4 is a partially exploded perspective view from the rear side of the air conditioner body. FIG. 5 is a partially enlarged perspective view from the rear surface side of the air conditioner main body.
A rear panel 60 is provided on the rear side of the air conditioner body 1a. The rear panel 60 includes a pipe connection hole 61 in which a resin lid 61A is fitted before installation, and an outside air introduction port 62 configured as a knockout panel in which a part is detachably punched.

The chamber partitioned by the rear panel 60 and the middle partition plate 43 constitutes the above-described blower chamber 13X, and the above-described electrical box 11 and blower 13 are disposed in the blower chamber 13X.

この場合において、外気導入口６２は、電装箱１１、送風機１３を構成するモータ２５およびこれらに用いられる電気コネクタなどのうち少なくとも何れかを含む電装部品に、導入した外気が直接的に当たらない位置、かつ、配管の設置の邪魔にならない位置に設けられている。
ここで、外気導入口６２を電装箱１１、送風機１３を構成するモータ２５およびこれらに用いられる電気コネクタなどのうち少なくとも何れかを含む電装部品に、導入した外気が直接的に当たらない位置に配置するのは、これらの部品に外気が触れて結露などが生じ、部品の劣化などを招くのを抑制するためである。この場合に、電装箱１１、モータ２５、電気コネクタなどの部品は、排気孔などの開口が必要な部分を除き、シーリングが施されている。
これらの条件を満たす後面パネル６０上の位置としては、図３および図４に示す幅方向範囲Ａ１および幅方向範囲Ａ２で示される領域が考えられるが、実施形態では、幅方向範囲Ａ２で示される領域内に外気導入口６２が設けられている。In this case, the outside air introduction port 62 is a position where the introduced outside air does not directly hit the electrical component including at least one of the electrical equipment box 11, the motor 25 constituting the blower 13, and the electrical connector used for these. And it is provided in a position that does not interfere with the installation of the piping.
Here, the outside air introduction port 62 is arranged at a position where the introduced outside air does not directly hit the electrical component including at least one of the electrical equipment box 11, the motor 25 constituting the blower 13, and the electrical connector used for these. The reason for this is to prevent the outside air from coming into contact with these components to cause dew condensation and the like, leading to deterioration of the components. In this case, parts such as the electrical equipment box 11, the motor 25, and the electrical connector are sealed except for portions that require opening such as exhaust holes.
As the position on the rear panel 60 that satisfies these conditions, the region indicated by the width direction range A1 and the width direction range A2 shown in FIGS. 3 and 4 can be considered, but in the embodiment, it is indicated by the width direction range A2. An outside air inlet 62 is provided in the region.

さらにこれに加えて実施形態では、外気導入口６２は、送風機１３を構成する送風機ユニット（ファン）２１、２２に外気が直接的に導かれる位置に設けられている。この結果、確実に外気を導入して、循環空気と混合して送出することが可能となっている。
さらに、この外気導入口６２は、送風機１３を構成する送風機ユニット（ファン）２１、２２の送風能力に応じ、吸込グリル３７を介して循環される室内の空気と導入した外気との混合比率が所定の比率となるような開口面積を有するように設定されている。所定の比率としては、循環空気に対する外気の混合比率が１０〜２０％程度（通常１５％程度）となるように設定されている。
本実施形態によれば、空気調和装置の運転時に外気を容易に導入して確実に換気を行えるとともに、外気の導入に伴う空気調和装置内における結露などを防止し、長期にわたって空気調和装置の運用が可能となる。In addition to this, in the embodiment, the outside air introduction port 62 is provided at a position where outside air is directly guided to the blower units (fans) 21 and 22 constituting the blower 13. As a result, it is possible to reliably introduce outside air, mix it with circulating air, and send it out.
Further, the outside air introduction port 62 has a predetermined mixing ratio between the indoor air circulated through the suction grille 37 and the introduced outside air according to the blowing capacity of the blower units (fans) 21 and 22 constituting the blower 13. The opening area is set so that the ratio is The predetermined ratio is set so that the mixing ratio of outside air to circulating air is about 10 to 20% (usually about 15%).
According to this embodiment, outside air can be easily introduced and reliably ventilated during operation of the air conditioner, and condensation in the air conditioner due to the introduction of outside air can be prevented, and the operation of the air conditioner can be performed over a long period of time. Is possible.

以上の説明においては、外気導入口を一つ設ける場合について説明したが、空気調和器本体のサイズに応じて複数箇所に設けるように構成することも可能である。より具体的には、例えば、図３および図４に示した幅方向範囲Ａ１で示される領域および幅方向範囲Ａ２で示される領域のそれぞれに外気導入口を設けるようにすればよい。
また、以上の説明においては、外気導入口をノックアウトバネルとして構成する場合について述べたが、あらかじめ後面パネル６０に外気導入口をあけておき、目隠し板をダクト取付用ねじ孔６３を利用して取り付けておくように構成することも可能である。
さらに、以上の説明においては、外気導入口の形状を円形状としていたが、楕円形状や多角形形状など任意の形状とすることが可能である。In the above description, the case where one outside air inlet is provided has been described, but it is also possible to provide a plurality of locations depending on the size of the air conditioner body. More specifically, for example, an outside air inlet may be provided in each of the region indicated by the width direction range A1 and the region indicated by the width direction range A2 shown in FIGS.
In the above description, the case where the outside air introduction port is configured as a knock-out panel is described. However, the outside air introduction port is opened in the rear panel 60 in advance, and the blindfold is attached using the duct attachment screw hole 63. It is also possible to configure so as to keep them.
Furthermore, in the above description, the shape of the outside air introduction port is a circular shape, but may be an arbitrary shape such as an elliptical shape or a polygonal shape.

また、以上の説明においては、吸込グリルが固定型の場合について説明したが、吸込グリルを４本の吊紐を介して空気調和機本体に支持し、これらの吊紐が繰り出され、或いは巻き戻されることで、所定の範囲で昇降し、吸込グリルを下げた位置で、この吸込グリルに載せられたフィルタを取り外し可能にした吸込グリル昇降装置を備えた空気調和装置においても適用が可能である。
この場合に、吸込グリル昇降装置をサイドカバー内に収容する構成とすると、外気導入口を設けられるスペースは、後面パネルが好ましいので、本実施形態の適用対象として好適となる。
以上の説明においては、外気導入口を後面パネルに設ける場合を説明したが、サイドカバー側に設けるように構成することも可能である。Further, in the above description, the case where the suction grille is a fixed type has been described. However, the suction grille is supported on the air conditioner body via four hanging straps, and these hanging straps are fed out or unwound. Therefore, the present invention can also be applied to an air conditioner equipped with a suction grill lifting device in which a filter placed on the suction grill is removable at a position where the suction grill is lowered within a predetermined range.
In this case, when the suction grill lifting device is configured to be accommodated in the side cover, the space provided with the outside air inlet is preferably a rear panel, and thus is suitable as an application target of the present embodiment.
In the above description, the case where the outside air introduction port is provided on the rear panel has been described. However, the outside air introduction port may be provided on the side cover side.
