Description
以下、実施の形態1に係る空気調和機の室内機1について説明する。実施の形態1では、空気調和機の室内機1が天井に取付けられて、ビル用マルチエアコンとして利用される場合を例にして説明をする。室内機1は、熱媒体として水が流れる熱媒体配管を介して、熱源機にて生成された温熱又は冷熱を室内機1に供給する中継器と接続されている。
図5は、実施の形態2に係る室内熱交換器112を示す分解斜視図である。図6は、実施の形態2に係る室内熱交換器112を示す分解斜視図である。図5及び図6は、分解された状態の室内熱交換器112を示している。また、図5と図6とは、室内熱交換器112を異なる角度から示している。図5及び図6に示すように、本実施の形態2に係る室内熱交換器112は、ヘッダ143が第3の板状部材181を有する点で実施の形態1と相違する。本実施の形態2では、実施の形態1と同一の部分は同一の符合を付して説明を省略し、実施の形態1との相違点を中心に説明する。
実施の形態2の変形例1では、第2の板状部材62及び第3の板状部材181は、樹脂からなる。第2の板状部材62と第3の板状部材181とは、超音波等よって溶着される。第1の板状部材61と第2の板状部材62とは、間に第3の板状部材181を配置した状態でねじによって締結されている。このように、室内熱交換器112のヘッダ143は、ロウ付けを行う大型の装置を用いずに製造されている。
