　－運転動作－
　空気調和装置（1）の基本的な運転動作について、図１を参照しながら説明する。空気調和装置（1）は、冷房運転と暖房運転とを実行可能に構成される。 -Driving operation-
The basic operating operation of the air conditioner (1) will be described with reference to FIG. The air conditioner (1) is configured to be capable of performing cooling operation and heating operation.
　冷房運転では、図示しない室外ユニットの圧縮機で圧縮された冷媒が、室外熱交換器で放熱（凝縮）し、膨張弁で減圧される。減圧された冷媒は、室内ユニット（10）の室内熱交換器（17）で蒸発し、圧縮機で再び圧縮される。 In the cooling operation, the refrigerant compressed by the compressor of the outdoor unit (not shown) is dissipated (condensed) by the outdoor heat exchanger and decompressed by the expansion valve. The decompressed refrigerant evaporates in the indoor heat exchanger (17) of the indoor unit (10) and is compressed again in the compressor.
　室内ファン（16）が運転されると、室内空間の空気が吸込口（21）からケーシング（11）の内部に吸い込まれる。ケーシング（11）の内部に吸い込まれた空気は、室内熱交換器（17）を通過する。室内熱交換器（17）では、冷媒が空気から吸熱することで空気が冷却される。冷却された空気は、吹出口（25）を通過した後、室内空間へ供給される。 When the indoor fan (16) is operated, the air in the indoor space is sucked into the casing (11) from the suction port (21). The air sucked into the casing (11) passes through the indoor heat exchanger (17). In the indoor heat exchanger (17), the air is cooled by the refrigerant absorbing heat from the air. The cooled air is supplied to the indoor space after passing through the outlet (25).
　ここで、室内熱交換器（17）で空気が露点温度以下にまで冷却されると、空気中の水分が凝縮する。このようにして発生した凝縮水は、ドレンパン（30）へ適宜回収される。ドレンパン（30）に回収された凝縮水は、ドレンポンプ（32）によってケーシング（11）の外部へ排出される。 Here, when the air is cooled to below the dew point temperature by the indoor heat exchanger (17), the moisture in the air condenses. The condensed water generated in this way is appropriately recovered in the drain pan (30). The condensed water collected in the drain pan (30) is discharged to the outside of the casing (11) by the drain pump (32).
　一方、暖房運転では、室外ユニットの圧縮機で圧縮された冷媒が、室内ユニット（10）の室内熱交換器（17）で放熱（凝縮）し、膨張弁で減圧される。減圧された冷媒は、室外ユニットの室外熱交換器で蒸発し、圧縮機で再び圧縮される。このため、室内熱交換器（17）では、冷媒が空気に放熱し、空気が加熱される。 On the other hand, in the heating operation, the refrigerant compressed by the compressor of the outdoor unit is radiated (condensed) by the indoor heat exchanger (17) of the indoor unit (10) and decompressed by the expansion valve. The decompressed refrigerant evaporates in the outdoor heat exchanger of the outdoor unit and is compressed again in the compressor. Therefore, in the indoor heat exchanger (17), the refrigerant dissipates heat to the air and the air is heated.
　〈付加装置の取付作業〉

　－実施形態の効果－
　ドレンポンプ（32）が支持部材（35）で支持され、ケーシング（11）の内部に配置される。付加装置本体（41）は、取付部（50）によって支持部材（35）に取り付けられる。 -Effect of embodiment-
The drain pump (32) is supported by the support member (35) and placed inside the casing (11). The additional device body (41) is attached to the support member (35) by the attachment portion (50).
　このように、ドレンポンプ（32）が支持される支持部材（35）を、付加装置（40）の支持部材（35）としても使用することで、付加装置（40）を容易に取り付けできる。また、部品点数を削減することができる。 In this way, by using the support member (35) on which the drain pump (32) is supported also as the support member (35) of the adder (40), the adder (40) can be easily attached. In addition, the number of parts can be reduced.
　支持部材（35）の下方又は側方に取付部（50）が取り付けられる。これにより、天井（C）に設置される室内ユニット（10）に対して、支持部材（35）の下方又は側方から付加装置（40）の取り付け作業を行うことができ、サービス性が良好となる。 The mounting part (50) is mounted below or to the side of the support member (35). As a result, the additional device (40) can be attached to the indoor unit (10) installed on the ceiling (C) from below or from the side of the support member (35), and the serviceability is good. Become.
　具体的に、支持部材（35）の上方には、ケーシング（11）の断熱部材（12）が存在する。そのため、支持部材（35）の上方から付加装置（40）を取り付けようとすると、ケーシング（11）の断熱部材（12）が邪魔になって作業し難い。これに対し、支持部材（35）の下方又は側方には、作業スペースが十分に確保されているので、容易に付加装置（40）を取り付けることができる。 Specifically, above the support member (35), there is a heat insulating member (12) of the casing (11). Therefore, when the additional device (40) is to be attached from above the support member (35), the heat insulating member (12) of the casing (11) becomes an obstacle and it is difficult to work. On the other hand, since a sufficient working space is secured below or to the side of the support member (35), the additional device (40) can be easily attached.
　また、既設の室内ユニット（10）に対して付加装置（40）を後付けする際には、天井空間に配置されている室内ユニット（10）に対して、メンテナンス作業者は下方からアクセスする。そのため、支持部材（35）の上方ではなく下方又は側方に付加装置（40）を取り付ける方が、メンテナンスを行い易い。 Also, when retrofitting the additional device (40) to the existing indoor unit (10), the maintenance worker accesses the indoor unit (10) arranged in the ceiling space from below.
