一、吸顶式冷风机工作原理：依靠轴流风机使冷库内的空气通过冷风机中的蒸发器进行强制循环，在蒸发器中进行热交换冷却空气，从而达到降温目的。吸顶式冷风机分类：吸顶式冷风机装在冷库房平顶之下，不占用库房面积。根据吸顶式冷风机的送风形式，可分为单面送风和双面送风；根据它的翅片形式，有绕片式和套片式。氟利昂冷风机一般是单向吸顶套片式，

冷却管一般用D10—20的紫铜管，其外套有0.2～0.3mm的薄铝肋片。为了使吸顶式冷风机出口的制冷剂有一定的过热度，冷风机中制冷剂的走向与空气的流向一般采用错流。二、吸顶式冷风机结构特点：1、吸顶式冷风机的蒸发器是由紫铜管和铝翅片构成，紫铜管采用真空退火工艺，具有很高的清洁度和可弯性，铝翅片一般采用二次翻片一次冲压成型工艺，紫铜管与铝翅片经机械胀管后结合牢固紧密，具有很高的传热效果。
