Summary

A heat pump clothes dryer comprises of two closed loops, namely, the heat pump cycle and the air cycle. Clothes dryers are among the most energy-intensive home appliance. This study experimentally investigated how the textile type, textile size, textile weight, fan speed, and compressor frequency influence the drying time and power consumption. A heat pump tumble dryer with a 9 kg rated capacity was selected for experimental investigations. The following values were selected for experiments: textile weight: 3, 6, 9 kg; textile type:
sheet, pillowcase, towel; fan speed: 2850, 3150, 3450 rpm; and compressor frequency; 27, 35, 40 Hz. Results showed that the drying time and power consumption were increased by increasing the textile weight and the textile size. The drying time of 9 kg sheets was 42.2% and 22.5% higher than that of pillowcases and towels, respectively. Moreover, the drying time was decreased by increasing the fan speed and compressor frequency.
