発明が解決しょうとする課題  Problems to be solved by the invention
[0003] ところで、従来の空気調和装置は、室内の空気を循環させるだけで換気の機能は 持って ヽな 、のが通常であった。 [0003] By the way, conventional air conditioners usually have a ventilation function only by circulating indoor air.
一方、近年、シックハウス症候群が大きな社会問題になっている。例えば、日本の 建築基準法では、住宅の居室には、 24時間常時運転可能なもので、換気回数 0. 5 回 Zh以上 (2時間で住宅の気積 (容積)を入れ替える能力)の換気設備を設置する ことが義務付けられている。  On the other hand, in recent years, sick house syndrome has become a major social problem. For example, according to the Building Standards Law of Japan, a living room in a house must be able to operate 24 hours a day, with a ventilation rate of 0.5 times Zh or more (the ability to replace the air volume (volume) of a house in 2 hours). Is required to be installed.
[0004] し力しながら、室内に空気調和装置の他に換気設備を設けることは、設備コストが 増大することとなる。ひいては、空気調和装置システム全体の設置面積も必要となる[0004] However, providing ventilating equipment in addition to the air conditioner in the room while increasing the equipment cost increases. As a result, the installation area of the entire air conditioning system is also required.
。さらに、空気調和装置と換気設備とを連結するダ外などにより室内の美観も損ねる こととなる。 . Furthermore, the appearance of the room will be impaired due to the outside of the air conditioner and the ventilation equipment connected.
そこで、本発明の目的は、空気調和装置の運転時に外気を容易に導入するととも 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 運用可能な空気調和装置を提供することにある。 Therefore, an object of the present invention is to easily introduce outside air during the operation of the air conditioner, to prevent dew condensation in the air conditioner due to the introduction of outside air, and to provide a long-term operation.

[0006] この場合にお 、て、前記外気導入口は、取り外し自在なノックアウトパネルとして構 成されていてもよい。 [0006] In this case, the outside air inlet may be configured as a removable knockout panel.
また、前記電装部品は、前記送風機を構成する送風機モータ、電装箱あるいは電 気コネクタのうち少なくとも 、ずれかを含むようにしてもよ 、。  Further, the electrical component may include at least one of a blower motor, an electrical box, and an electrical connector that constitute the blower.
さらに、前記外気導入口は、前記送風機を構成するファンに外気が直接的に導か れる位置に設けられて 、るようにしてもょ 、。  Further, the outside air inlet may be provided at a position where outside air is directly guided to a fan constituting the blower.
[0007] さらにまた、前記外気導入口は、前記送風機を構成するファンの送風能力に応じ、 前記吸込グリル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してもょ 、。 [0007] Further, in the outside air introduction port, a mixing ratio of room air circulated through the suction grille and the introduced outside air becomes a predetermined ratio according to a blowing capacity of a fan constituting the blower. It may have such an opening area.
また、前記所定の比率は、要求される単位時間当たりの換気能力に応じて定めら れるようにしてもよい。  Further, the predetermined ratio may be determined according to a required ventilation capacity per unit time.
