Abstract

　この発明は、高圧側が気液二相領域または超臨界領域で運転される冷媒を用い、熱負荷や温度条件の変動に対しても高いＣＯＰを維持した運転を行うことで省エネルギ化を図ることができる冷凍サイクル装置およびその運転制御方法を提供する。 　この発明による冷凍サイクル装置では、制御手段１９が、検出器１１～１８から得られた冷媒情報をもとにした熱負荷と温度条件とから高圧圧力目標値を設定し、圧縮機１の回転数、電子式膨張弁４の開度、室外ファン３の回転数、および室内ファン７の回転数の少なくとも１つを制御して、高圧圧力を設定された高圧圧力目標値に合うように制御する。この時、高圧圧力目標値を設定する際に閾値を設け、高圧圧力目標値を設定する時点での高圧圧力が閾値以上の場合と閾値未満の場合とで、高圧圧力目標値の設定方法を変更する。
