Description
液面センサー28からの信号に基づき、冷媒配管(リターン配管) 18iに設けた調整弁24を制御することにより、低圧受液器15内の冷媒液量が所定量以上となった場合に、高圧受液器13からブースターポンプ17で送り出されて来る冷媒液を冷媒配管18iを通して高圧受液器13内へ戻し、低圧受液器15内の冷媒液が所定以上の量になるのを防ぐ。また、低圧受液器15と冷媒液ポンプ20の間に圧力センサー30が設けられている。そして、図示しない制御部が圧力センサー25と圧力センサー30で検出される冷媒圧力に応じて、前記ブースターポンプ17の駆動と停止の制御を行うようにしている。

Claims (1)
- 冷媒圧縮機、凝縮器、高圧受液器、膨張弁、低圧受液器、冷媒液ポンプ及び蒸発器が順次接続された循環冷媒回路を備え、冷凍若しくはヒートポンプサイクルを構成した冷凍システムにおいて、
前記高圧受液器と前記低圧受液器の間に、前記高圧受液器側の圧力が前記低圧受液器内の圧力よりも低下した場合に、前記高圧受液器側の冷媒液を昇圧して前記低圧受液器側へ強制的に送り込むブースターポンプを設け、
前記凝縮器または前記高圧受液器と前記低圧受液器の間に、調整弁を有し前記高圧受液器からの冷媒液を該凝縮器または該高圧受液器側に戻す冷媒リターン回路を設け、
前記低圧受液器内の冷媒液の量を検出する液面センサーからの信号に基づき前記調整弁を制御することにより、前記低圧受液器内の液量に応じて、前記高圧受液器からの冷媒液を該凝縮器または該高圧受液器側に戻すことを特徴とする冷凍システム。
