Heat pump dehumidification unit

The utility model belongs to the technical field of the dehumidification and specifically relates to indicate heat pump dehumidification unit, including the runner, regeneration system is connected to the tamper on the runner, and drying system is connected to the treatment region, drying system sees the dry wind off including heat exchanger, first evaporimeter and first condenser, return air or atmosphere in proper order behind heat exchanger, first evaporimeter, runner treatment region and first condenser, regeneration system is including second condenser, regenerative heater and second evaporimeter, and the new trend is seen in proper order off to the atmosphere behind the tamper of second condenser, regenerative heater, runner and second evaporimeter. The utility model discloses the runner is gone into the wind gap and is carried out heat transfer, water separation branch and adjust vapour concentration etc. Humid air, and the dehumidification of reentrant runner further promotes runner dehumidification efficiency, is equipped with second condenser, regenerative heater and second evaporimeter on the tamper of runner, and the moisture content of runner can effectively be detached to this structure, recovers the drying process function of runner, obtains stable dehumidification performance.
