一概述制冷装置中空气冷却的蒸发器包括冷库蒸发排管、冻结间冷风机盘管、热泵的空冷蒸发器等,在生产使用过程中,管子外表面会结霜。霜层由薄转厚,影响使用。霜的形成主要是因为空气中含有一定水分,随着管内冷剂的蒸发,管外温度不断降低,空气的相对湿度不断增大,当管壁周 An overview of the cooling unit in the air-cooled evaporator evaporator, including cold storage, air-cooled intercooler coil, heat pump air-cooled evaporator, in the production process, the outer tube surface will frost. Frost layer from thin to thick, affect the use. The formation of frost is mainly due to the air contains a certain amount of water, with the evaporation of the tube refrigerant, outside the tube temperature continues to decrease, the relative humidity of the air continues to increase, when the tube wall weeks
