Abstract
Setting-up the right greenhouse environment is subject to complex requirements. Present conditions real time parameters are analyzed from the viewpoint of greenhouse heating and ventilation system demands in winter period. Insufficient amount of heat energy gained from geothermal source during the low outside air temperatures period and unused geothermal heat energy in periods when heating system is not required are discussed. Complex environmental parameters modeling necessary for greenhouse heating and ventilation yearly energy requirements is provided. Numerical simulations are performed to provide energy efficiency improving, effective geothermal source use, defining heat storage system and conceptual technical design. Finally, needs for further research and engineering development are outlined.
Određivanje unutrašnjih parametara u plastenicima i staklenicima zahteva kompleksno razmatranje u cilju određivanja optimalnih sistema grejanja prostor au zimskom periodu i ventilacije u letnjem periodu. U cilju povećanja energetske efikasnosti objekta razmatrano je grejanje objekta energijom geotermalnog izvora, kao i modeliranje potrošnje geotermalne vode u uslovima nedovoljne količine pri izuzetno niskom temperaturama spoljašnjeg vazduha. Numeričke simulacije toplotnog opterećenja plastenika sprovedene su u cilju povećanja efektivne upotrebe izvora geotermalne energije i konceptualnih tehničkih rešenja. U radu je definisano termičko ponašanje objekta. Konačno, potreba za daljim istraživanjem i inženjerskim razvojem je naglašena.
