　水蒸汽达到饱和状态的压缩空气进入干燥机的预冷器中，在预冷器里，进入的热空气被出去的冷空气先冷却降温一部分，减少了系统的负荷（此过程为预冷）。预冷后的空气进入蒸发器。在这里，空气放出的热量被冷媒吸收，冷却到预先设定的温度(2~7℃)。空气被冷却后就使水蒸汽结成液滴，并通过汽水分离器从空气中分离出来，又经自动排水器排出机外，离开汽水分离器后，冷空气进入预冷器的壳程，与入口热空气进行热交换，在被加热到大约与入口空气相差10℃后离开干燥机。这种再加热防止外部出口空气管路和下游管路的二次结露，还增加了空气的能量，提高了效用。此外，压缩空气经过干燥机后，其中的3μ及以上固体尘都已被滤除，气源品质达到清洁、干燥的要求。

Water vapour saturated state of the compressed air into the dryer precooler, in precooler, into the hot air is out of the cold air cooling first part, reduce the system load (the process of precooling). Pre-cooled air enters the evaporator. Here, the air is released heat absorbed by refrigerant and cooling to the preset temperature (2 ~ 7 ℃). After it was cooled air to water vapor into droplets, and through the steam separator separates from the air, and the automatic drainer discharge closed, after leaving the steam separator, the shell side of the cold air entering the precooler and heat exchange with the hot air entrance, the difference between inlet air is heated to about 10 ℃ after leave the dryer. This reheating prevents the secondary flow of external air lines and downstream pipes, and increases the energy of the air and increases the utility. In addition, after the compressed air passes through the dryer, the three mu and the above solid dust have been filtered, and the gas source quality is required to clean and dry.
