【0070】 [0070]
製氷用ファン(31)は、圧縮機(41)と同期運転をしており、冷凍室(9)の設定温度を低くすると、設定温度に対して実際の室内温度が高くなり、圧縮機(41)は冷凍能力を増加させるために回転数を上げることになる。 Ice fan (31) includes a compressor (41) has a synchronous operation, lowering the set temperature of the freezing compartment (9), the actual room temperature becomes higher than the set temperature, the compressor (41 ) would raise the rotational speed to increase the cooling capacity. これにより、圧縮機(41)と同期運転をしている製氷ファン(31)の回転数も自動的に高くなり、冷凍能力が増加さるため迅速な製氷を行うことができる。 Thus, the rotational speed of the ice fan compressor (41) has a synchronous operation (31) becomes automatically high refrigerating capacity can be performed monkey for quick ice increases.

【0072】 [0072]
<変更例7> <Modification 7>
ポンプダウンモード中は、製氷用ファン(31)を運転させるものである。 During pump-down mode is to be operated the ice making fan (31). ポンプダウンは冷却モードの切り替え時に行うものであり、冷凍用冷却器(27)の冷媒をより早く圧縮機(41)に回収するほうがよい。 Pump down is to carry out at the time of switching the cooling mode, it is better to recover refrigerant in the earlier compressor (41) a refrigeration cooler (27). 製氷用ファンを運転することで冷凍空間の空気と冷凍用冷却器との熱交換量を増加させることができるので、冷媒回収を迅速に行うことができる。 It is possible to increase the amount of heat exchange between the air and the freezing cooler of the refrigeration space by operating the ice making fan, it is possible to perform refrigerant recovery quickly.
