Vpliv hitrostnih razmer na vstopu na karakteristiko radialnega ventilatorja

Pipp, Peter (author), Hočevar, Marko (mentor)

V sušilnikih perila želimo z ventilatorjem doseči velike pretoke in tlake. Velik pretok omogoča boljše prepihovanje perila v bobnu in s tem bolj učinkovit ter krajši čas sušenja. Vpliv vstopnikov na karakteristiko radialnega ventilatorja smo določili na merilni postaji, kjer smo izmerili delovne karakteristike in krivulje izkoristka ter z anemometrom na vročo žičko izmerili hitrostno polje na vstopu ventilatorja. Iz rezultatov smo ugotovili izboljšanje zmogljivosti in učinkovitosti merjenega ventilatorja v primeru obrnjenega vstopnika glede na privzet položaj le-tega v sušilnem stroju perila.

• Title: Influence of velocity conditions at the entrance to the radial fan characteristics

Abstract

In tumble dryers, we want to achieve high flows and pressures with the fan. High flows enable better blowing of the laundry and thus more efficient and shorter drying time. The influence of the entrances on the characteristic of the radial fan was determined at the measuring station where the performance and efficiency curves were measured and the velocity field at the inlet of the fan was determined with the hot wire anemometer. From the results, we found improvement in the performance and efficiency of the measured fan in the case of an inverted entrance according to its default position in the tumble dryer.
