蒸發器的分類　Classification of evaporator

　　冷藏庫中使用的蒸發器主要有兩種：一是冷風機，二是排管蒸發器（無縫鋼管鐵排和鋁排）。

　　冷風機因安裝簡單、維修方便是近10年來冷藏庫中使用較多的形式，但在多年使用過程，食品風幹、變色及其較大的耗能和故障率高等弊端越來越突出。

There are mainly two kinds of evaporators in the refrigerating house:air cooler and coil evaporator(seamless ssteel tube(iron coil)and aluminum coil).The seamless steel tube(also called iron coil) for low-temperature house plays a role of cold accumulation.

The air cooler is the most common form for refrigerating house in thelast decade,but after long-term use,the weak points like the food gets dried and changes color,power consumption gets larger,failure ratio gets higher,etc will be more and more prominent.

　　DD吊頂冷風機可與不同製冷量的壓縮冷凝機組配套使用。用於庫溫-18℃左右的冷庫中，可低溫貯藏肉類、魚類等冷凍食品；DL係列適用於溫度為0℃左右的冷庫，可冷卻貯藏水果、蔬菜、禽蛋；DJ

係列適用於-23℃以下的凍結庫，可凍結肉類、不產品等。

　　DD suspended air cooler can be used in the refrigerating house at about-18℃together with compressor& condenser unit of diffeent refrigerating capacity as refrigerating equipment.It is can store meat ,fish and other frozen food.DLseries is suitable for the refrigerating house at about 0℃ which can store vegetables,fruits, poultry and eggs;DJ series is suitable for freeze house below-23℃ which can store meag,aquatic product.
