20.500.12556/RUL-141026 Influence of load mass, drum speed and load composition on evenness of drying in a heat pump tumble dryer This work investigates the evenness of fabric drying in a household heat pump tumble dryer. The evenness of drying was defined as the standard deviation of the fraction of water, evaporated from each fabric item. Drying experiments were performed according to the IEC 61121 standard, which was also followed to determine quantities and types of cotton fabric items (towels, pillowcases and sheets) within each load. Regression analysis was performed to develop models for evenness of drying as a function of load mass and drum speed. Similarities between the tumble dryer energy efficiency parameters and the evenness of drying were analyzed. A high level of agreement was determined between responses of energy efficiency, drying time and evenness of drying to changes in drum speed. Effects of load mass were however more complex and were reflected in a non-linear response of evenness of drying to changes in load mass – the best evenness of drying could be obtained at 2 kg load, followed by 6 kg and 4 kg load. Load composition was determined as an important factor affecting the evenness of drying. At larger loads, a sheet or a pillowcase in average contributed more to the un-evenness of drying than a towel. The presence of sheets and probably the ratio of sheets to other item types in the load were determined as the most probable factors that negatively affected the evenness of drying. heat pump tumble dryers evenness of drying regression analysis energy efficiency sušilniki perila s toplotno črpalko enakomernost sušenja regresijska analiza energijska učinkovitost true false true Angleški jezik Slovenski jezik Članek v reviji 2022-09-22 08:34:42 2022-09-22 08:34:44 2022-09-29 04:03:33 0000-00-00 00:00:00 2022 0 0 Str. 2175–2187 iss. 10 Vol. 40 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.577:648.336 0737-3937 10.1080/07373937.2021.1928688 65575939 Influence_of_load_mass_drum_speed_and_load_composition_on_evenness_of_drying_in_a_heat_pump_tumble_dryer.pdf Influence_of_load_mass_drum_speed_and_load_composition_on_evenness_of_drying_in_a_heat_pump_tumble_dryer.pdf 1 AB407558F694A1872D710DFF281026F2 fc6348200afbe0c21d3c50b870dba3f5180454140529ec801dfa1ff66e9509df 7cea4d36-3f0c-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=162332 https://www.tandfonline.com/doi/full/10.1080/07373937.2021.1928688 0 91bb60f5-3a40-11ed-92af-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=161905 Fakulteta za strojništvo 0 0 0
