V doktorskem delu so raziskani vplivi parametrov zraka na vstopu v boben na proces sušenja v sušilnem stroju z odprtim pretočnim sistemom. Izdelani so bili regresijski modeli za izračun specifičnega časa sušenja, hitrosti uparjanja vlage in produkta snovske prestopnosti in površine perila. Večji pre ...

Oznake:
heat pump tumble dryers;energy consumption;drying time;regression analysis;
The use of heat pump tumble dryers is nowadays more common because they offer huge energy savings compared to conventional tumble dryers. Earlier studies made on conventional tumble dryers have shown that parameters such as heater power, fan speed, drum speed, weight and initial moisture content of ...

heat pump tumble dryers;evenness of drying;regression analysis;energy efficiency;
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 f ...

The condensation of humid air is a crucial step in air conditioning and process engineering. However, the models that describe the condensation of vapour in the presence of a non-condensable gas require time-consuming numerical calculations that go beyond the Nusselt film theory. Only a small number ...
