Abstract

V diplomskem delu smo s pomočjo računalniškega programa na osnovi računalniške dinamike tekočin izvedli nestacionarno numerično analizo toplotnih in tokovnih razmer v srednje veliki pisarni, kot primer prostora hlajenega s klasično termostatsko krmiljeno »split-system« klimatsko napravo. Prav tako smo na podlagi rezultatov toplotnega in tokovnega polja določili faktor ugodja, ki je bil pričakovano rahlo neugoden zaradi neenakomerne porazdelitve temperaturnega polja v prostoru in prevelikega nihanja temperature s časom, ki ga povzroča termostatsko krmiljena klimatska naprava.

Secondary title: Computer analysis of heat and flow conditions in HVAC environment
Secondary abstract: In this diploma work we performed a non-steady numerical analysis of heat and flow conditions using the Computational Fluid Dynamics in middle sized office room, used for the example of HVAC environment, which is cooled down using classic thermostatic controlled »split-system« air conditioner. On the basis of the results of heat and flow field we also defined thermal comfort factors which, like we expected, predict slightly uncomfortable thermal environment. This is mainly caused by irregular distribution of heat and flow field and too high peak-to-peak variation of temperature cycles that occur due to the thermostatic control of the air conditioner.
