Problems solved by technology

Although this treatment process reduces the regeneration temperature requirement by setting two-stage dehumidification rotors 101 and 103, the evaporative cooler 105 is used to perform isenthalpic humidification on the dehumidified air, resulting in the offset of dehumidification and humidification, which limits the performance of the device Level
