通过建立冰箱箱壁式冷凝器和冰箱风冷式冷凝器的传热和流动压降理论数模，计算得出在相同环境条件，制冷量和体积容量相同的两台冰箱因冷凝换热形式的改变而引起的能效差异。结果显示：翅片管风冷式冷凝器替代自然对流箱壁式冷凝器后，无论从节能上还是经济节约上来说都具有较大的优势。

The heat transfer and pressure drop models of natural convective hot-wall condenser of refrigerator and forced convective finned condenser of refrigerator are built, the difference energy efficiencies of the above two kinds refrigerators were calculated under the condition of same refrigeration capacity, same volume and same environment condition.The results show that the refrigerator used forced convective finned condenser has more advantages both in energy saving and economy.
