Abstract

　　蒸発器（14）の冷却能力を調節しながら圧縮機（11）および庫内ファン（16）を運転する第１動作と、第１動作中に庫内の吹出側空気温度が設定温度に維持されると、蒸発器（14）の冷却能力を増大させて設定温度を含んだ目標範囲の下限温度まで吹出空気温度を引き下げた後、圧縮機（11）および庫内ファン（16）を停止する第２動作と、第２動作の後、吹出側空気温度が目標範囲の上限温度まで上昇すると、第１動作を再開させる第３動作とを行う省エネ運転モードを備えている。そして、省エネ運転モードは、第２動作の後に庫内の吸込側空気温度が制限値まで上昇すると、庫内ファン（16）を第１動作時よりも低風量で起動させるように構成されている。
