Description

本発明は天井設置形ファンコイルユニットに関するものである。   The present invention relates to a ceiling-mounted fan coil unit.

従来の天井設置形のファンコイルユニットは、１つのケーシングの内部に熱交換コイルとファンを取付けてあり、ケーシングを完全に分解しないと熱交換コイルやファンを取り外せない構造であった。そのため、製作後に熱交換コイルの熱源出入口の向き、いわゆる配管勝手を反対にしたり、熱交換コイルやファンを交換・変更するのが困難で、手間がかかる問題があった。   A conventional ceiling-mounted fan coil unit has a structure in which a heat exchange coil and a fan are attached inside one casing, and the heat exchange coil and fan cannot be removed unless the casing is completely disassembled. For this reason, it is difficult to reverse the direction of the heat source inlet / outlet of the heat exchange coil, that is, so-called piping after the manufacture, or to exchange / change the heat exchange coil or fan, which is troublesome.
