The best condition of heat pump drying was analyzed and calculated by equivalent temperature method. The concept of optimum evaporation temperature of heat pump dryer was put forward, which is instructive for energy saving operation of heat pump dryer. The drying effects of different refrigerants are compared, and the energy saving principle of the regenerative cycle is studied.
