EKSPERIMENTALNA KALIBRACIJA MODELA PODZEMNIH TRANSFERA TOPLINE ISPOD VINSKIH GRAĐEVINA U SEOSKIM PODRUČJIMA ; EXPERIMENTAL CALIBRATION OF UNDERGROUND HEAT TRANSFER MODELS UNDER A WINERY BUILDING IN A RURAL AREA
Površinske temperature i hidrogeološki uvjeti ključni su parametri u mnogim inženjerskim primjenama poput izgradnje podruma i drugih podzemnih prostorija te kod procjene plitkoga geotermalnog potencijala. Međutim, teško je otkriti prirodne, tj. izvorne, toplinske uvjete, poglavito u plitkim, podzemnim, gradskim područjima. Razlog tomu je ljudski utjecaj. Stoga procjena toplinskih varijabli u takvim uvjetima postaje sve važnija, jer raste i uporaba geotermalne energije, posebice kao obnovljivoga izvora. Cilj rada bio je prikazati trodimenzionalni model takvih uvjeta, kalibriran eksperimentalnim podatcima. Tako je opisano ponašanje topline u podzemlju pod utjecajem građevina u odabranome seoskom području Italije. Temperaturne varijacije u prostoru i vremenu ovisile su o površinskim stijenama (i/ili tlu), klimi i svojstvima same građevine. Svi ti parametri razmatrani su unutar modela sezonskih promjena temperatura. Rezultati modela u područjima niske urbanizacije neizravno upućuju kako promatrani parametri imaju veliku važnost u visoko urbaniziranim područjima. Nadalje takvi rezultati mogu se uključiti u buduće modele plitkoga podzemlja i razmjenjivača topline te unaprijediti kako njih, tako i opću uporabu geotermalne energije. ; Ground temperature and hydrogeological conditions are key parameters for many engineering applications, such as the design of building basements and underground spaces and the assessment of shallow geothermal energy potential. Especially in urban areas, in the very shallow depths, it is diffi cult to fi nd natural undisturbed underground thermal conditions because of anthropic interventions. The assessment of underground behaviour in disturbed conditions will become more and more relevant because of increasing awareness to energy effi ciency and renewable energy topics. The purpose of this paper is to show a three-dimensional representation - based on models calibrated on experimental data - of the underground thermal behaviour aff ected by a building in a rural area in Italy. Temperature varies in space and time and it depends on ground, climate and building characteristics, and all these parameters are taken into account by the seasonal periodic modelling implemented. The results obtained in a context of low urbanization indirectly suggest the importance of these eff ects in dense urban areas; taking greater account of these aspects could lead to improvements in the design of underground spaces and geo-exchanger fi elds for geothermal energy exploitation.
