Description
本発明の実施の形態1に係る空気調和装置について説明する。図1は、本実施の形態に係る空気調和装置100の冷媒回路構成を示す冷媒回路図である。図1に基づいて、冷凍サイクル装置の1つである空気調和装置100の冷媒回路構成及び動作について説明する。この空気調和装置100は、冷媒を循環させる冷凍サイクル(ヒートポンプサイクル)を利用して、冷房運転又は暖房運転を行うものである。なお、図1では、実線矢印が冷房運転時における冷媒の流れを示しており、破線矢印が暖房運転時における冷媒の流れを示している。また、図1を含めた以下の図面では、各構成部材の大きさの関係が実際のものとは異なる場合がある。
本発明は、上記実施の形態に限らず種々の変形が可能である。
例えば、上記実施の形態では熱源側熱交換器3を例に挙げたが、本発明は利用側熱交換器101にも適用可能である。
