Summary:To provide a refrigerator which includes a small-type condenser in which heat transfer efficiency has been improved, and which can prevent closing of this condenser.SOLUTION: A refrigerator 10 has adopted a microchannel condenser 23 as a condenser. Also, in cooling a refrigeration chamber 12 and the like by operating a refrigeration cycle, a calculation control part 24 circulates the air in one direction with respect to the microchannel condenser 23 by rotating a blower 21 in one direction. On the other hand, in performing a defrosting step for defrosting an evaporator, the calculation control part 24 circulates the air in the reverse direction with respect to the microchannel condenser 23 by rotating the blower 21 in the reverse direction. Thereby, deterioration in the heat conduction efficiency can be suppressed caused by dust accumulating in the microchannel condenser 23.SELECTED DRAWING: Figure 2 【課題】熱伝達効率が向上された小型の凝縮器を備えると共に、この凝縮器の閉塞を防止することができる冷蔵庫を提供する。【解決手段】本発明の冷蔵庫10では、凝縮器としてマイクロチャンネルコンデンサ23を採用している。また、演算制御部24は、冷凍サイクルを運転することで冷蔵室12等を冷却する際には、送風機21を一方向に回転させることで、マイクロチャンネルコンデンサ23に対して一方向に空気を流通させる。一方、演算制御部24は、蒸発器を除霜する除霜行程を行う際には、送風機21を逆方向に回転させることで、マイクロチャンネルコンデンサ23に対して逆方向に前記空気を流通させる。これにより、マイクロチャンネルコンデンサ23に埃が堆積することで熱伝導効率が低下してしまうことを抑止できる。【選択図】図2
