【課題】複数の圧力スイッチに相当する接続部品の数量を削減する。【解決手段】冷凍装置（10）には、作動する冷媒の設定圧力が互いに異なるように構成され、作動することで接点を開くスイッチ部（41a,42a,43a）をそれぞれ有する複数の圧力スイッチ（41,42,43）と、複数の圧力スイッチ（41,42,43）のスイッチ部（41a,42a,43a）が直列に接続されるスイッチ回路（40）と、スイッチ回路（40）が非通電状態になるときに、少なくとも、冷媒回路（11）の圧力に相当する物理量に基づいて、どの圧力スイッチ（41,42,43）が作動したかを判定する判定部（51）とが設けられる。【選択図】図２ |
