Abstract

　冷凍サイクル装置１００は、第１圧縮機１０１と、第１圧縮機１０１に対して並列に設けられた第２圧縮機１０２と、圧縮機１０１，１０２で圧縮された冷媒を冷却する放熱器１０３と、放熱器１０３で放熱した冷媒を膨張させつつ動力を回収する膨張機１０４と、膨張機１０４で膨張した冷媒を蒸発させる蒸発器１０５と、膨張機１０４による回収動力が第１圧縮機１０１で使用されるように第１圧縮機１０１と膨張機１０４とを連結している回転軸１２３と、蒸発器１０５に高温の冷媒を流すことによって蒸発器１０５に付着した霜を溶かす除霜運転において、冷媒の流量を徐々に増やすステップを含む制御を行うコントローラ１１２とを備えている。
