Abstract

　　圧縮機（21）及び室外熱交換器（22）を有する室外ユニット（20）と、室内熱交換器（31）を有する室内ユニット（30）とを備え、室外ユニット（20）と室内ユニット（30）とによって冷媒回路（40）のメイン回路（43）が構成されている。一端がメイン回路（43）の液ライン（4a）に接続され且つ他端がメイン回路（43）の低圧ガスライン（4a）に接続され、メイン回路（43）の冷媒を貯留するサブ回路（70）を備えている。サブ回路（70）は、サブ通路（71）に設けられ、メイン回路（43）の冷媒を貯留する冷媒調節器（72）と、液ライン（4a）及び低圧ガスライン（4a）と冷媒調節器（72）との連通及び遮断を行うための切換機構（73）とを備えている。メイン回路（43）の冷媒量が過剰になると、メイン回路（43）の余剰冷媒を冷媒調節器（72）に貯留する。
