Description
また、どのような配管長の連絡配管が選択されても、適時目標値を補正できる。さらに該圧力損失については、圧縮機吸入に設けられた圧力センサーと室内熱交換器出口の温度センサーにて容易に算出できる。これにより、配管長が長く圧力損失が大きい連絡配管を施工された室内熱交換器の冷房効果低下を防止できる。
つまり、室内熱交換器が複数台ある即ち連絡配管が複数経路ある中で、最小圧力損失の連絡配管経路の補正をすることで、他の室内熱交換器の圧力が必要以下になることを防止している。
媒は室内熱交換器用膨張弁16によって膨張され(膨張区間C―D1)低温・低圧の気液二層流となり、室内熱交換器5に送られる。室内熱交換器5においては、気液二層流冷媒は冷房を行う室内から吸熱すると共に冷却されて(蒸発区間D1−E1)飽和状態となって圧力損失を伴う連絡配管42を通って(圧力損失区間E1―A1)、圧縮機2へ再び吸入される。

Claims (1)
- 室内熱交換器と室外熱交換器間を、冷媒が循環する空気調和装置であって、冷房運転時に室内熱交換器の出口の冷媒温度に基づく冷媒圧力と、圧縮機吸入圧力との差より配管圧力損失を算出し、冷房運転の圧縮機吸入圧力の目標値を、前記配管圧力損失分だけ減算補正する空気調和装置において、前記室内熱交換器が複数接続され、該室内熱交換器の出口の冷媒温度に基づく冷媒圧力の情報が複数ある場合には、それらの最低圧力と圧縮機吸入圧力との差より配管圧力損失を算出し、冷房運転の圧縮機吸入圧力の目標値を該配管圧力損失分だけ減算補正することを特徴とする空気調和装置。
