Rotating wheel dehumidification and regeneration high-temperature heat pump system

The utility model relates to a rotating wheel dehumidification regeneration high-temperature heat pump system which is characterized in that a normal-temperature heat pump system, a medium-temperature heat pump system and a high-temperature heat pump system are sleeved on an airflow pipeline in a dehumidification rotating wheel regeneration circulation system in series; the dehumidification rotating wheel regeneration circulation system, the normal-temperature heat pump system, the medium-temperature heat pump system and the high-temperature heat pump system are all regeneration closed circulation systems, and external emission is avoided. The utility model has the following advantages: 1, regeneration closed circulation, no external emission, no pollution and no waste; secondly, the regeneration energy of the multi-stage heat pump is saved by more than 50%, sensible heat and latent heat are fully recovered, and the energy-saving effect is prominent and substantive; and thirdly, free refrigeration is carried
