Energy -conserving drying system of heat pump intelligence

The utility model discloses an energy -conserving drying system of heat pump intelligence, including heat pump system and dry return circuit, heat pump system is including compressor, condenser, throttling arrangement and the evaporimeter of looping in in proper order, and dry return circuit includes circulating fan, drying chamber and air conduit, air conduit is equipped with by -pass line and isfurnished with the governing valve in thermal coupling department with the evaporimeter. The utility model discloses the aim at that the evaporimeter set up by -pass line make damp and hot air through the evaporimeter can be betterly with the evaporimeter in the refrigerating output phase -match to exert the dehumidifying capability of evaporimeter fully, simultaneously, can also making it to match through the heating load of governing valve regulation condenser and evaporimeter betterly, compromising two respective requirements of unit in heat pump system and the dry return circuit, the operability is stronger when
