Furthermore, the front ends of the regeneration areas of the rotary dehumidifier are respectively provided with a regeneration heater.
Furthermore, the rotary dehumidifier of the second stage is provided with two regeneration areas, cold air output by the second stage surface cooler enters a second stage rotary dehumidifier from one regeneration area of the second stage rotary dehumidifier for dehumidification, is heated by a corresponding regeneration heater, enters the second stage rotary dehumidifier from the other regeneration area of the second stage rotary dehumidifier for secondary dehumidification, is heated by a corresponding regeneration heater of the first stage rotary dehumidifier, and then enters the first stage rotary dehumidifier.
And furthermore, a return air fan is connected in series between the dehumidification area of the first-stage rotary dehumidifier and the filter at the front end of the second-stage surface cooler, and the return air fan is connected with the clean room through a pipeline.
After the technical scheme is adopted, the utility model has the beneficial effects that: the water in the air is cooled to the dew point by the two-stage surface cooler, and water drops in the air are absorbed by the two-stage rotary dehumidifier, so that the aim of controlling the humidity is fulfilled. The dehumidified air is sent into the clean room after being subjected to heat exchange by the surface cooler and temperature adjustment by the heater, so that the requirement of temperature setting of the clean room is met. In order to avoid the accumulation of water vapor in the clean room, air in the clean room is pumped out through a return air branch and is sent to a rotary dehumidifier for repeated dehumidification; this technical scheme can be with the humidity control in the clean room at lower level.
