冷库冷风机是冷库蒸发器的一种，冷库冷风机的作用是将冷库热力膨胀阀的低温低压的饱和制冷剂通过冷风机与被冷却介质发生热交换，将饱和制冷进行气化并且带走冷库内部热量的换热设备，冷库冷风主要由冷却换热排管轴流风机、分液器容霜装置、骏水盘等5大安部分组成，来自冷库冷凝器的高压常温液态制冷剂经过执力膨胀阀节流后直接进入冷库风机的分液器，进行均匀分液后送入换热排管进行气化吸热，而冷库风机的轴流风机则负责将冷库机和冷库内空气进行强制对流循环达到冷库制冷的目的

由于冷库怒发器外边的温度低于O℃，随着制冷时间的增加，冷库冷风机外表面会出现霜层，产生这些霜层后不仅严重影响冷库风机的换热系数，还会导致冷库冷风机循环风量的大大减少，这样一来就会影响冷库冷风机的换热量，使冷库设备的运转性能严重下降，为了保证冷库冷风机有良好的换热性能，就必须对冷库冷风机进行容霜工作，目前冷库冷风机常见的容霜方式为电热容霜，电热容霜具有容霜彻底、能实现自动控制等众多优点，受到很多小型医药冷库、蔬菜冷库工程的青睐

The cold storage chiller is a cold storage chiller. The function of the cold storage chiller is to exchange the low temperature and low pressure saturated refrigerant of the cold storage thermal expansion valve with the cooled medium through the chiller to vaporize the saturated refrigeration and take away the heat inside the cold storage. The cold storage of the cold storage of the heat exchange equipment is mainly composed of the cooling heat exchange tube axial flow fan, the liquid separator, the frost-proof device, the Chunshui plate, etc. The 5 high-ampere-level liquid refrigerant from the cold storage condenser is directly throttled by the forced expansion valve after throttling. The liquid separator of the cold storage fan is evenly divided and sent to the heat exchange tube for gasification and heat absorption. The axial flow fan of the cold storage fan is responsible for the forced convection circulation of the air in the cold storage machine and the cold storage to achieve the purpose of cold storage refrigeration.

Because the temperature outside the cold storage anger device is lower than the OC, the cooling surface will increase. The frost layer on the outer surface of the cold storage chiller will not only seriously affect the heat transfer coefficient of the cold storage fan, but also cause the circulation of the cold storage fan to be greatly reduced. Reducing this will affect the heat exchange capacity of the cold storage chiller, which will seriously reduce the running performance of the cold storage equipment. In order to ensure the good heat exchange performance of the cold storage chiller, the cold storage chiller must be frost-proof. Currently, the cold storage chiller is the most common. The frost-receiving method is electric heating cream, electric heating cream has the advantages of complete frost tolerance, automatic control, etc., and has received many small medicine cold storage and vegetable cold storage projects.
