IMPROVING THE ENERGY EFFICIENCY OF HEATING BY THE APPLICATION OF HEAT INSULATION

U radu je analizirano toplinsko opterećenje zgrade za tri slučaja. U prvom slučaju zgrada je bez izolacije, a time ima veće gubitke. U drugom slučaju uzeta je izolacija debljine 10 cm, koja je smanjila toplinsko opterećenje, a time su smanjeni gubici, dok u trećem slučaju uzeta je izolacija debljine 20 cm te su gubitci dodatno smanjeni. U radu su opisane vrste grijanja te je napravljena njihova podjela. Napravljen je proračun koji uzima u obzir debljinu izolacije od 10 cm. S obzirom na toplinsko opterećenje prostorije odabrana su ogrjevna tijela proizvođača Lipovica. Dimenzionirana je cijevna mreža , te su proračunati padovi tlaka za najkritičnije dionice. Odabran je kotao EKO – CK P 110 proizvođača Centrometal. Grafički pomoću dijagrama opisani su gubitci na zgradi, proračunat je potrebni utrošak električne energije i plina za zgradu, te je izračunata emisija CO2 za razdoblje grijanja.In this thesis building heat losses are analized in three study cases. In first case is analized building without isolation which causes bigger heat losses. In second case building has 10 cm tick isolation which reduced heat losses, in third case building has 30 cm tick isolation which reduce heat losses even more. In this thesis heating types were described and classificated. For second case study calucation were made. Considering heat losses radiators Lipovica were chosen. The piping network were dimensioned, and the pressure drops for the most critical shares were calculated. Boiler EKO – CK P 110 of manufacturer Centrometal was chosen.Graphically using diagrams building losses were described and required electricity and gas consumption for the building were calculated. The CO2 emissions heating period were also calculated for the building
