Pri načrtovanju sistema lokalne ventilacije se optimizaciji odsesovalne nape pogosto nameni premalo pozornosti. Razlog za to je predvsem neraziskanost in pomanjkanje znanja na tem področju. Toda z razvojem primerne nape za dano aplikacijo bi lahko precej izboljšali učinkovitost zračnega odvajanja oz ...

Učinkovitost delovanja sušilnih strojev s toplotno črpalko je tesno povezana z medsebojno
odvisnostjo med vlažnim sušilnim zrakom in tokokrogom toplotne črpalke. V okviru naloge
smo opisali teoretično ozadje delovanja sušilnega stroja s toplotno črpalko v povezavi z
delovanjem parno-kompresijskega c ...

Tumble drying of textiles is associated with mechanical and thermal stress,which leads to textile damage and shedding of fibers. In this study, fibershedding from cotton textiles is investigated by evaluating the mass of fibersaccumulated on different filters positioned downstream of the tumble drye ...

Drying of the sewage sludge layer was investigated in a convective laboratory dryer at air temperatures of 65 °C and 80 °C and air speeds of 0.53 m/s and 0.83 m/s. The sludge layer was formed by loading cylindrical extrudates on a grate of 0.5 m x 0.5 m size. The drying air was directed through the ...

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 ...
