Taking wet towels as the research object, a far-infrared-assisted heat pump dryer was designed and manufactured. Wet towels were dried by using a heat pump (HP) dryer combined with far-infrared radiation (FIR) with the power of 500, 1000 and 2000W. Changes of drying chamber inlet air temperature, outlet air temperature, inlet air humidity, outlet air humidity, inlet sample temperature, middle sample temperature and outlet sample temperature were all studied. The experiments were conducted under pump drying and far-infrared-assisted drying with different powers. The results showed that compared with the pump drying treatment, the dehumidification capacity was improved effectively, with values of 8.1% to 22.2%. The present data suggested that far-infrared-assisted heat pump drying could shorten the drying time, improve the drying efficiency.
