Abstract

本発明の課題は、冷媒の流動音の発生を抑制することで、運転時の騒音の発生を低減することにある。冷凍装置（１）は、超臨界冷媒を利用し、高圧圧力が臨界圧力以上の領域で作動する冷凍装置であって、圧縮機（２１）と、ガスクーラ（２３，３１）と、膨張機構（Ｖ２，Ｖ５）と、蒸発器（３１，２３）と、吐出圧力検出手段（Ｐ１，Ｔ２，Ｔ３）と、制御部（５）とを備える。圧縮機は、超臨界冷媒を圧縮する。ガスクーラは、圧縮機で圧縮された超臨界冷媒を冷却する。膨張機構は、超臨界冷媒を減圧する。蒸発器は、膨張機構で減圧された超臨界冷媒を蒸発させる。吐出圧力検出手段は、圧縮機の吐出圧力を検出可能である。制御部は、起動時、かつ、吐出圧力が臨界圧力未満である場合に、膨張機構の開度を調整して、吐出圧力が臨界圧力以上になるように制御する。
