Abstract

　開度可変の膨張弁（13）が設けられた冷媒回路（20）を備える冷凍装置（10）は、下限指令値以上の大きさの開度の指令値を膨張弁（13）に出力することによって膨張弁（13）の開度を制御する弁制御手段（33）を備えている。弁制御手段（33）は、冷凍サイクルの実行中に開度の指令値が下限指令値に等しくなる下限制御状態で、膨張弁（13）と圧縮機（11）の吸入側との間の冷媒の状態に基づいて膨張弁（13）を通過する冷媒流量が過多状態になっているか否かを判定する第１判定動作を行い、第１判定動作で膨張弁（13）を通過する冷媒流量が過多状態になっていると判定した場合には、下限指令値を小さな値に補正する。
