Description
前記外気温度感応式冷暖房装置(100)は、冷媒を圧縮して排出する圧縮機(110)、圧縮機(110)と第1冷媒主配管(210)に連結される負荷側熱交換器(120)、負荷側熱交換器(120)と第2冷媒主配管(220)に連結されて液化された冷媒が貯蔵される受液器(140)、受液器(140)が収容される水槽(130)、受液器(140)と第3冷媒主配管(230)に連結されて水槽(130)に配置される水槽用熱交換部(150)、受液器(140)と水槽用熱交換部(150)を連結する第3冷媒主配管(230)上に配置される膨張弁(190)、水槽用熱交換部(150)と第4冷媒主配管(240)に連結される潜熱熱交換器(160)、第5冷媒主配管(250)を介して第4冷媒主配管(240)に連通するとともに、第6冷媒主配管(260)を介して圧縮機(110)に連通する液分離器(180)及び温度感知管路(270)を介して本発明の第6冷媒主配管(260)に連結される外気温度感知ユニット(170)を含む。
一方、図5を参照し、他の実施例による外気温度感応式冷暖房装置(100')を説明する。
以下、本発明の外気温度感応式冷暖房装置(100)の暖房モードを説明すると、次の通りである。暖房モードにおける冷媒の変化は、圧縮→第1凝縮→第2凝縮→膨張→蒸発→圧縮の循環システムによって成される。
次に、本発明の外気温度感応式冷暖房装置(100)の冷房モードを説明すると、次の通りである。冷房モードにおける冷媒の変化は、暖房モードと同様に、圧縮→第1凝縮→第2凝縮→膨張→蒸発→圧縮の循環システムによって成される。ただし、負荷側熱交換器(120)における機能が暖房モードとは反対に進められる。即ち、負荷側熱交換器(120)は暖房モードで凝縮機能を遂行するが、冷房モードでは蒸発機能を遂行する。
次に、本発明の外気温度感応式冷暖房装置(100)の蓄熱及び蓄冷モードを説明すると、次の通りである。
前述の通り、制御部は外気温度感知ユニット(170)から感知される外気温度によって前記各冷媒主配管及び各冷媒補助配管に配置された開閉弁に選択的に開閉信号を提供することによって蓄熱または蓄冷モードが選択的に行われるようにする。
具体的には、外気温度感知ユニット(170)から感知される外気温度が既設定された温度より高ければ蓄熱モードが行われるようにし、外気温度感知ユニット(170)から感知される外気温度が既設定された温度より低ければ蓄冷モードが行われる。
蓄熱された熱は前述の冷房モードで水槽用熱交換部(150)に流入される冷媒を加熱して冷房に使用される。
蓄冷用クーラー(161)で冷却された冷媒は、第2冷媒補助配管(320)及び第2冷媒主配管(220)を通じて水槽(130)内の補助凝縮用熱交換部(145)に移送され、熱を放出し、水槽(130)内の水により過剰冷却されて冷却し、受液器(140)に貯蔵されることによって、水槽(130)内の水により蓄冷が行われる。
