Abstract

　冷凍装置である空調機（10）の冷媒回路（20）には、複数台の室外ユニット（30,40）が接続される。第１室外ユニット（30）が運転されて第２室外ユニット（40）が休止する運転状態において、この空調機（10）は、第２室外ユニット（40）の第２室外熱交換器（42）へ余剰の冷媒を回収して保持するための冷媒回収動作を行う。この冷媒回収動作中には、第２室外膨張弁（43）が全閉状態となり、第２室外ファン（46）が運転される。冷媒回収動作中の第２室外熱交換器（42）へは、第１圧縮機（31）から吐出された冷媒の一部が流入する。第２室外熱交換器（42）へ流入した冷媒は、室外空気へ放熱して凝縮する。第２室外膨張弁（43）は全閉状態であるため、第２室外熱交換器（42）には凝縮した冷媒が溜まり込む。
