Large air superconducting cold recovery dehumidification unit

The utility model relates to a large air dehumidification unit (100,000-50,0000m /h), in particular to a large air superconducting cold recovery dehumidification unit capable of recovering energy. The large air superconducting cold recovery dehumidification unit can reduce energy consumption of large air dehumidification units, sufficiently uses cooled air temperature, can recover energy, uses superconducting media as the media, and can save 35-45% of energy. The large air superconducting cold recovery dehumidification unit comprises an air dehumidification unit, wherein a cooling section air cooler poured with cold water is arranged in the air dehumidification unit, and a copious cooling section air cooler poured with ethylene glycol is arranged on the back section of the cooling section air cooler. The large air superconducting cold recovery dehumidification unit is characterized in that a pre-cooling section air cooler is additionally arranged on the front section of the cooling section air cooler, a back-heating section air cooler is additionally arranged on the back section of the copious cooling section air cooler, and the pre-cooling section air cooler is in series connection with the back-heating section air cooler through the superconducting media serving as the media.
