Abstract
Description
図1は、本発明の実施の形態1における空気調和装置のシステム構成図である。この空気調和装置は、四方弁2を切り換えることによって冷房運転と暖房運転とを切り換えることができるものである。本発明は、暖房運転時に適用できるものであるため、以下では暖房運転に特化して説明する。
暖房運転時は圧縮機1から吐出される高温高圧のガス冷媒(状態A)が四方弁2を通って負荷側熱交換器3に流れる。高温高圧のガス冷媒は負荷側熱交換器3で熱交換して低温高圧の過冷却状態の液冷媒となる(状態B)。負荷側熱交換器3を流出した液冷媒は、内部熱交換器4に流入する。内部熱交換器4では、負荷側熱交換器3を流出して内部熱交換器4の高圧側流路に流入した高圧側冷媒と、内部熱交換器4の低圧側流路の低圧側冷媒とが熱交換され、内部熱交換器4の高圧側流路に流入した高圧側冷媒は冷却される(状態C)。
サブクールSC=「冷媒の凝縮温度」−「負荷側熱交換器3の出口温度:状態Bにおける温度」
状態Bのエンタルピーは、図2の状態B→Cにおける、内部熱交換器4での高圧側流路での熱交換量Q1と、図2の状態D→Kにおける、内部熱交換器4での低圧側流路での熱交換量Q2とが等しいと仮定して、状態Bのエンタルピーを算出する。
