Claims (1)
- 商品収容庫の内部に配設され、自身を通過する冷媒と該商品収容庫の内部空気とを熱交換させる庫内熱交換器と、吸引した冷媒を圧縮する圧縮機と、前記商品収容庫の外部に配設され、自身を通過する冷媒と周囲空気とを熱交換させる庫外熱交換器と、供給された冷媒を断熱膨張させる膨張機構とを冷媒管路で順次接続して構成された循環経路と、
前記圧縮機で圧縮された冷媒を前記庫内熱交換器に導入させるための導入経路と、
前記導入経路を通じて前記庫内熱交換器に導入された冷媒を前記庫外熱交換器に導出させるための導出経路と、
前記導出経路を通じて前記庫外熱交換器に導出された冷媒を前記圧縮機に帰還させるための帰還経路と
を備えた冷媒回路を有する冷媒回路装置であって、
前記導入経路は、前記圧縮機と前記庫外熱交換器とを接続する冷媒管路から分岐して、前記膨張機構と前記庫内熱交換器とを接続する冷媒管路に合流する態様で設けられ、
前記導出経路は、前記庫内熱交換器と前記圧縮機とを接続する冷媒管路から分岐して、前記圧縮機と前記庫外熱交換器とを接続する冷媒管路に合流する態様で設けられ、
前記帰還経路は、前記庫外熱交換器と前記膨張機構とを接続する冷媒管路から分岐して、前記圧縮機の吸引部分に接続する態様で設けられ、
