Description
このような接合部の破損は冷媒の漏洩の原因となり、装置の運転が安定して行なわれなくなるという問題を惹き起すだけでなく、例えばアンモニアのような毒性を有する冷媒を使用する場合には、負荷側へ供給する冷却媒体への有毒冷媒の混入や装置周囲への有毒ガスの漏洩という重大な問題の原因となる。
圧縮機1の吐出口に一端が接続された吐出管2の他端が切替弁たる四方弁3の第1ポート3aに接続され、同四方弁3の第2ポート3bに一端が接続された第1冷媒管4の他端が、第1の熱交換器たる空気熱交換器5、第1逆止弁6および第1膨張弁7を介して第2の熱交換器たる水熱交換器8の第1冷媒管接続口8aに接続されている。
なお上記水熱交換器8は、小型で熱交換効率の高い熱交換器、例えばブレージングタイプのプレート熱交換器で構成してある。
なお、図中の符号16a、16bは冷媒管接続口を示している。
なお、図1中の水熱交換器8およびサブ熱交換器16の冷媒出入口および水出入口には各部位における冷媒や水の温度の値の例を付した。

Claims (4)
- 圧縮した冷媒を吐出する冷媒圧縮機と、冷房運転時には凝縮器として作用し、暖房運転時には蒸発器として作用する第1の熱交換器と、冷房運転時には蒸発器として作用し、暖房運転時には凝縮器として作用して負荷側へ送られる水等の冷却媒体と熱交換する第2の熱交換器を備え、冷房運転時には圧縮機からの吐出冷媒が第1の熱交換器、第2の熱交換器の順に送られて圧縮機に戻され、暖房運転時には圧縮機からの吐出冷媒が第2の熱交換器、第1の熱交換器の順に送られて圧縮機に戻されるように、冷媒配管の途中に設けた切替弁によって切り替えられるヒートポンプ式冷凍装置において、前記第2の熱交換器と前記切替弁との間に第3の熱交換器を設け、負荷側からの冷却媒体が第3の熱交換器と第2の熱交換器をこの順に流過せしめるように構成してなるヒートポンプ式冷凍装置。
- 前記冷媒がアンモニアである請求項1に記載のヒートポンプ式冷凍装置。
- 前記第2の熱交換器の冷媒入口において冷房運転時に冷媒の減圧を行なう膨張弁の開度を、前記第3の熱交換器の冷媒出口温度に基づいて制御するように構成してなる請求項1に記載のヒートポンプ式冷凍装置。
- 前記切替弁は、暖房運転時において所要の時間的間隔で冷房運転時の状態に切り替えられて、前記第1の熱交換器における逆サイクルによる除霜運転が行なわれる構成としてなる請求項1に記載のヒートポンプ式冷凍装置。
