D型系列空氣冷卻器（又稱冷風機）是 一種適用于各種冷庫（如土建冷庫或組合冷 庫）的冷卻降溫設備。D型系列空氣冷卻器有 DL、DD和DJ型三種型式，分別適用于不同 庫溫的冷庫，它具有結構緊湊，重量輕，不 占用冷庫使用面積，庫溫均勻，效率高等優 點，使冷庫內貯藏的食品迅速降溫，大大提 高了貯藏食品的保鮮度。
水沖霜冷風機是一種配套于不適用電熱除霜成者要求快速除霜的冷庫使用的庫內降溫設備，根據適 用溫度可分為SDL、SDD、SDJ三個系列，分別適用于0°C、-18°C、及-25°C左右的冷庫使用。該系列 產品具有如下特點：外殼采用優質鋼板、表面噴塑、耐腐蝕，外型美觀；盤管采用錯排或平行兩種方 式，利用機械脹管，使銅管與翅片緊密結合，換熱效果好；采用水沖霜，除霜速度快、效果好、能耗 小；可根據客戶要求采用長距離送風或防爆型電機。
Water defrosting cooling fan is a kind of cooling equipment in the cold storage that is not suitable for electric defrosting and requires rapid defrosting. It can be divided into three series: SDL, SDD and sdj according to the applicable temperature, which are respectively suitable for cold storage at 0 degrees, - 18 degrees and - 25 degrees. This series of products have the following characteristics: the shell is made of high-quality steel plate, the surface is plastic sprayed, corrosion-resistant and beautiful; The coils are staggered or parallel, and the mechanical expansion is used to make the copper tube closely combined with the fins, with good heat exchange effect; Water defrosting is adopted, which has the advantages of fast defrosting speed, good effect and low energy consumption; Long distance air supply or explosion-proof motor can be used according to customer requirements.
D型系列空氣冷卻器可與不同制冷量的壓縮機組配套，用于不同庫溫的冷庫中。作為制冷設備， 其中DL型適用于庫溫為（TC左右的冷庫，如保存鮮蛋或蔬菜的冷庫；DD型適用于庫溫為-18° C左右 的冷庫，作為肉類、魚類等冷凍食品的冷藏用；DJ型適用于庫溫為-25。。的冷庫，作為鮮肉或鮮魚制 品或調理食品的速凍用0
