Abstract
In this study, the performance characteristics of a high temperature heat pump dryer that is able to raise the air temperature up to $80^{\circ}C$ by using waste heat as heat source were investigated numerically. The main components of the heat pump dryer were modeling as a compressor, condenser, evaporator and expansion device, and R245fa was selected as refrigerant. Experiments were also conducted to validate the numerical data. As a result, when the evaporator air inlet temperature increased from $50^{\circ}C$ to $65^{\circ}C$, the numerical results of the hot air temperature at outlet and heat pump COP were about 8~11% and 5~8% higher than that of experimental ones, respectively.
