In this study, the operating performance of the heat pump dryer using the PF heat exchanger was experimentally studied. The capacity, COP, drain, SMER and operating status of the cooling cycle of the heat pump dryer were investigated according to the temperature, relative humidity and flow rate of the indoor air. Heat pump dryers are refrigerant-air system. For the dryer performance experiment, an air enthalpy calorimeter was used. From the experimental results, as the temperature, relative humidity, and flow rate of the inlet air increased, the capacity, COP, drain, SMER of the dryer increased. The change in the performance of the dryer was most affected by temperature. The P-h diagram of the cooling system showed that the operation status of the dryer was greatly affected by the indoor temperature. In addition, the SMER of the dryer showed a drying performance of about 3.38 kg/kWh or more within all experimental ranges.
