Claims (6)
- 冷凍貯蔵空間および冷蔵貯蔵空間をそれぞれ専用に冷却する冷凍用および冷蔵用冷却器と冷気を循環する冷却ファンとを設け、流路切換弁によって冷媒流路を前記冷凍および冷蔵用冷却器に交互に切り換えて冷却するとともに、冷凍用冷却器から冷蔵用冷却器へ冷媒流路を切り換える際には双方の冷却器に冷媒を流す同時冷却モード運転の後に冷蔵空間冷却モード運転をおこなうようにした冷蔵庫において、同時冷却モード運転時に、冷蔵用冷却器の冷媒入出口部の温度差が所定値以下であれば冷蔵用冷却器への流路抵抗を大きくし、所定値以上であれば同流路抵抗を小さくすることを特徴とする冷蔵庫。
- 冷凍貯蔵空間および冷蔵貯蔵空間をそれぞれ専用に冷却する冷凍用および冷蔵用冷却器と冷気を循環する冷却ファンとを設け、流路切換弁によって冷媒流路を前記冷凍および冷蔵用冷却器に交互に切り換えて冷却するとともに、冷凍用冷却器から冷蔵用冷却器へ冷媒流路を切り換える際には双方の冷却器に冷媒を流す同時冷却モード運転の後に冷蔵空間冷却モード運転をおこなうようにした冷蔵庫において、冷蔵用冷却器への流路抵抗を冷凍用冷却器の流路抵抗より小さくし、同時冷却モード運転時には、冷蔵用冷却器への流路抵抗を通常運転時の流路抵抗より大きくすることを特徴とする冷蔵庫。
- 冷蔵用冷却器への流路抵抗の調整は流路切換弁を兼ねた冷媒制御弁でおこなうことを特徴とする請求項1または2記載の冷蔵庫。
- 同時冷却モード運転時には、冷凍用および冷蔵用冷却器の冷気循環ファンの回転数を通常時より低回転にすることを特徴とする請求項1または2記載の冷蔵庫。
- 同時冷却モード運転時には、圧縮機の回転数を通常冷却時より高回転にすることを特徴とする請求項1または2記載の冷蔵庫。
- 同時冷却モードの運転終了後は、流路切換弁によって冷凍および冷蔵用冷却器への冷媒流を阻止し、各冷却器内の冷媒を圧縮機に回収する冷媒回収モード運転をおこなうことを特徴とする請求項1または2記載の冷蔵庫。
