PROBLEM TO BE SOLVED: To provide a cooling storage box capable of sufficiently defrosting an evaporator, and also suppressing power consumption necessary for the defrosting.SOLUTION: A method for defrosting an evaporator has two methods: a heater defrosting method and an off-cycle defrosting method. A control unit is configured to: when an in-box temperature is not less than an off-cycle defrosting termination temperature within 5 min right before starting defrosting the evaporator, determine that an amount of frosting is large, and then perform defrosting with the heater defrosting method; and when the in-box temperature is less than the off-cycle defrosting termination temperature, determine that the amount of frosting is small, and then perform defrosting with the off-cycle defrosting method.SELECTED DRAWING: Figure 4 【課題】蒸発器を十分に除霜しつつ除霜に要する消費電力量を抑制することができる冷却貯蔵庫を提供する。【解決手段】蒸発器の除霜方式にはヒータデフロスト方式とオフサイクルデフロスト方式とがあり、制御部は、蒸発器の除霜を開始する直前の５分以内に庫内温度がオフサイクルデフロスト終了温度以上であった場合は着霜量が多いと判断してヒータデフロスト方式によって除霜し、オフサイクルデフロスト終了温度未満であった場合は着霜量が少ないと判断してオフサイクルデフロスト方式によって除霜する。【選択図】図４
