Due to the large number of household tumble dryers a significant amount of energy is consumed, so their constant optimization is needed. In order to optimize the appliance, an experimental station for measuring process variables of drying process has been made. The paper presents the results of measured values of all experimental measurements at different speeds of the centrifugal fan. By understanding all the processes in a heat pump tumble dryer, we determined the optimization theory and set the best parameters for the speed regulation of the centrifugal fan. With the optimized process experimental results lower energy consumption was confirmed.
