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。
