Description
図1はこの発明の実施の形態の一例を示す冷凍冷蔵庫の冷媒回路図、図2は冷凍冷蔵庫の側面断面図である。この冷凍冷蔵庫の冷凍サイクルの冷媒には地球温暖化に非常に影響が小さい炭化水素系冷媒R600a(イソブタン)を用いている。
Claims (3)
- 密閉容器内に電動機と、この電動機にて駆動される圧縮要素が設けられ、この圧縮要素が低段側圧縮部と高段側圧縮部により構成された圧縮機と当該圧縮機の低段側圧縮部および高段側圧縮部、凝縮器、流路切換手段、前記流路切換手段に接続され冷蔵室用冷却器へ冷媒を流す第一の膨張手段、前記流路切換手段に接続され冷凍室用冷却器へ冷媒を流すように並列に設けられた低冷却負荷用の第二の膨張手段および高冷却負荷用の第三の膨張手段とから構成された冷凍サイクルと、冷蔵庫内温度検知手段、冷凍庫内温度検知手段、周囲温度検知手段、冷蔵室用庫内ファンおよび冷凍室用庫内ファンとを備え、前記冷蔵庫内温度検知手段および冷凍庫内温度検知手段がそれぞれ予め設定された設定温度より高い温度を検知した場合は、前記流路切換手段により前記第一の膨張手段と前記第二の膨張手段の両方を連通し、前記冷蔵庫内温度検知手段により検知された温度が設定温度より小さく、かつ前記冷凍庫内温度検知手段により検知された温度が設定温度より大きい場合は、前記流路切換手段により前記第三の膨張手段のみ連通し、前記冷蔵庫内温度検知手段により検知された温度が設定温度より大きく、かつ前記冷凍庫内温度検知手段により検知された温度が設定温度より小さくて、冷蔵室のみ冷却が必要と判断した場合に、前記流路切換手段により前記第一の膨張手段と前記第二の膨張手段の両方を連通して、冷蔵室および冷凍室を同時に冷却するように制御されたことを特徴とする冷凍冷蔵庫。
- 前記周囲温度検知手段より検知された信号を元に圧縮機回転数を決定するように制御されたことを特徴とする請求項1記載の冷凍冷蔵庫。
- 前記周囲温度検知手段より検知された周囲温度が予め設定された設定温度より低く冷却負荷が小さい場合は、前記流路切換手段にて冷凍室冷却用の膨張手段として前記第二の膨張手段を選定し、前記周囲温度が設定温度より高く冷却負荷が大きい場合は、前記流路切換手段にて前記第三の膨張手段を選択することを特徴とする請求項1または請求項2に記載の冷凍冷蔵庫。
