Abstract

　冷媒を圧縮する冷媒圧縮機１と、この冷媒圧縮機１で圧縮された冷媒を冷却し凝縮させる凝縮器１０と、この凝縮器１０で凝縮された冷媒を受け入れる受液器１１と、この受液器１１からの冷媒を膨張させる膨張機構１８と、この膨張機構１８で膨張させた冷媒と熱交換させて冷却対象を冷却し冷媒圧縮機１に供給される冷媒を蒸発させる蒸発機構１９と、補助冷媒を流通させ受液器１１内を通る配管４７を有し、この配管４７を流通する補助冷媒と熱交換させることにより冷媒圧縮機１の起動前に受液器１１内の冷媒を冷却する補助冷却機構６２とを備えた冷却サイクル系統６１を構成する。これにより、冷媒圧縮機の起動時の所要動力を低減し、起動時の発生トルクの小さな駆動源を用いても冷媒圧縮機を安定に起動することができる。
