Zaradi vedno strožjih zahtev po nizkoenergijskih objektih in učinkoviti rabi energije se v vse novogradnje vgrajuje mehansko prezračevanje v obliki rekuperatorjev ali regeneratorjev. V diplomskem delu je obravnavan potencialni način izdelave satovja, uporabljenega kot prenosnik toplote v lokalni prezračevalni napravi s pomočjo tehnologije ciljnega nalaganja. V ta namen je bila postavljena merilna proga, ki je omogočala merjenje vhodnih in izhodnih temperatur zraka skozi regenerator ter pretoke zraka. Z izmerjenimi veličinami smo lahko določili toplotno učinkovitost regeneratorja in specifično toploto 3D-natisnjenega satovja.

• Title: Manufacturing of honeycomb structure of ventilation device regenerator by FFF technology and characterisation

Abstract

Due to increasingly high requirements for low-energy buildings and efficient energy use, mechanical ventilation in the form of recuperators or regenerators is installed in all new buildings. The thesis discusses the potential method of making a honeycomb regenerator used as a heat exchanger in a local ventilation device using fused filament fabrication. Fort his purpose, a measuring line was set up, which enabled the measurement of inlet and outlet air temperatures and air flow trough the regenerator. With the measured values, we were able to determine the thermal efficiency of the regenerator and the specific heat of the 3D printed honeycomb.
