Abstract
Description
以下に、本発明に係る冷凍装置の構成及び動作を図示した実施の形態に基づいて説明する。図1は、本発明の実施の形態に係る冷凍装置の冷媒回路を概略的に示した模式図である。本実施の形態の冷凍装置1は、図1に示すように、圧縮機2、四方切替弁3、室外熱交換器4、膨張機構5及び室内熱交換器6を、順次冷媒配管で接続されて冷媒を循環させる冷媒回路を備えており、蒸気圧縮式の冷凍サイクル運転を行うことによって、屋内の冷暖房に使用される。
圧縮機2は、低圧のガス冷媒を圧縮して、高温、高圧のガス冷媒を吐出する。圧縮機2から吐出された冷媒は、四方切替弁3を通過して、室外熱交換器4に供給される。室外熱交換器4を冷媒が通過することで、高温、高圧のガス冷媒が凝縮され、高圧の液冷媒となる。室外熱交換器4を通過した液冷媒は、膨張機構5の膨張弁を通過して低圧の気液混合冷媒となり、室内熱交換器6に供給される。室内熱交換器6を通過した冷媒は、低圧の気液混合状態から、低温、低圧のガス冷媒となる。室内熱交換器6を通過した冷媒は、圧縮機2に供給される。
