Meritve toplotnega izkoristka decentralnih enot

Podpečan, Gregor (author), Stritih, Uroš (mentor)

Prezračevanje ima velik pomen na kakovost življenja. S prezračevanjem se srečamo vsak dan. Namen prezračevanja je dovajati v prostor svež zrak, onesnaženega pa odvajati. Z željo po zmanjšanju toplotnih izgub v stavbah vanje vgrajujemo nova okna in nanje nameščamo izolacijske materiale, kar posledično pomeni majn prezračevanja kot prej, večjo možnost nastanka vlage in slabšo kvaliteto zraka v prostoru. Idealna uporaba rekuperatorjev je prav za take stavbe, saj ne posegajo preveč v obnovo ali preureditev stavb. S konstantnim dovajanjem in odvajanjem zraka je potrebno zmanjšati toplotne izgube skozi rekuperator, prav tako pa je zrak, ki prihaja skozi rekuperator, prečiščen z filtri kar zmanjša kontaminacijo zraka z nevarnimi snovmi. Z merjenjem temperature in pretoka zraka rekuperatorjev ali decentralnih enot smo dokazali, kakšen je toplotni izkoristek decentralne enote oziroma decentralnega rekuperatorja.

• Title: Thermal test of decentralized heat exchanger units

Abstract

Ventilation has a big impact on life quality. Every person meets with ventilation every day. Purpose of ventilation is bringing fresh air in and carrying contaminated air out of the room. We wish to reduce heat loss in buildings therefore we instal new windows and insulation materials on buildings walls which means less ventilation and bigger chance of formation moisture and bad quality air in the room. Ideal use of decentralized heat exchange units is in that kind of buildings because we do not interfere with renewal or rearrangment of buildings. With constant circular supply of air there is a need of reducing heat loss through heat exchange units. Also air that is coming through heat exchange units is cleaned with filters which reduces contamination of incoming air. With measuring temperature and air flow of decentralized heat exchange units we have shown how efficient decentralized heat exchange unit really is.
