Claims (3)
- 1つの庫内(3)を冷却する独立した2系統の冷凍サイクル(11・12)を備えており、庫内(3)の設定温度(D0)が冷凍温度帯に属する冷凍運転と、該設定温度(D0)が冷蔵温度帯に属する冷蔵運転とが可能な保冷庫であって、
2系統の冷凍サイクル(11・12)が、冷蔵運転時に優先的に駆動を開始するメイン冷凍サイクル(11)と、メイン冷凍サイクル(11)の駆動中に所定の高負荷条件を満たした場合に追加的に駆動を開始するサブ冷凍サイクル(12)とで構成されており、
両冷凍サイクル(11・12)の駆動中に、庫内温度(D)が設定温度(D0)に基づくサブOFF温度(D2off)まで低下したとき、冷凍運転時であれば直ちにサブ冷凍サイクル(12)を停止させ、冷蔵運転時であれば所定の延長時間(TE)の経過後にサブ冷凍サイクル(12)を停止させることを特徴とする保冷庫。 - 前記延長時間(TE)の間、庫内(3)の空気を循環させる庫内ファン(10)を停止させる請求項1に記載の保冷庫。
- 前記延長時間(TE)の間、庫内(3)の空気を循環させる庫内ファン(10)を、該延長時間(TE)の前後よりも低速で駆動させる請求項1に記載の保冷庫。
