DESIGN OF HEATING, AIR CONDITIONING AND VENTILATION OF PUBLIC BUILDING

U radu je prikazano projektno rješenje sustava grijanja i hlađenja znanstveno obrazovne ustanove Strojarskog fakulteta koja se nalazi u ulici Ivana Gundulića 20A, Slavonski Brod. Uvodni dio rada temelji se na općenitom opisu grijanja i hlađenja, njihovih sustava i ogrjevnih/rashladnih tijela. Prema normi HRN EN 12831 za grijanje, te VDI 2078 za hlađenje izvršen je proračun projektnog toplinskog i rashladnog opterećenja znanstveno obrazovne ustanove. Na temelju dobivenih toplinskih gubitaka i dobitaka izvršen je odabir ogrjevnih/rahladnih tijela. Proračun je proveden u programu za tablično računanje Microsoft Excel. S obzirom na rezultate proračuna može se zaključiti da izolacija vanjskih zidova, i izolacija općenito, ima velike koristi i utjecaj na smanjenje gubitka i troškova kada bi se gledalo na cijelu zgradu odnosno kada bi u proračun bile uključene sve prostorije čiji su zidovi su velikom površinom u doticaju s vanjskom okolinom.In this thesis a design for the heating, cooling and air conditioning system for the scientific and educational institution of the Mechanical Engineering Faculty, located at Ivan Gundulić Street 20A, Slavonski Brod is presented. The introductory part of the paper offers general description of heating and cooling, their systems and heating/cooling bodies. The calculation for the heating and cooling load of the building of the scientific and educational institution was performed according to the HRN EN 12831 standard for heating and VDI 2078 standard for cooling. The selection of heating/cooling bodies was made based on the obtained heat losses and gains. The calculation was done in a Microsoft Excel spreadsheet. In view of the results of the calculation, it can be concluded that the insulation of external walls, and insulation in general, has great benefits and impact on the reduction of loss even if the entire cost of construction was considered, i.e. if the calculation included all rooms whose walls have a large area in contact with the external environment
