Abstract (Croatian)

U sklopu rada sam proveo analizu toplinskih karakteristika podnog konvektora i radijatora u režimu grijanja. Analizu sam proveo u Laboratoriju za toplinu i toplinske uređaje prema normi HRN EN 442-2 za tri različite temperature radnog medija. Također bilo je potrebno provesti mjerenja površinskih temperatura zidova ispitne sobe i usporediti ih s onima dobivenim prilikom ispitivanja radijatora. Rad je razrađen uvodom gdje sam opisao elemente ispitne sobe i normu HRN EN 442-2. Rezultate mjerenja analizirao prema normi te dao dodatnu usporedbu prema metodi iz VDI Heat Atlasa. U konačnici sam proveo parametarsku analizu i dao preporuke za poboljšanje konstrukcije s ciljem povećanja toplinskog učina. Na samom kraju nalazi se usporedba površinskih temperatura zidova za konvektor i radijator.

Abstract

In this work I conducted an analys of the thermal characteristics of the floor convector and radiator in the heating mode. Analysis were conducted in the Laboratory for heat and thermal devices according to norm HRN EN 442-2 for three different temperature of working fluid. Also this work contains measurements of the surface temperatures of the walls of the test room. This temperatures were compared with temperatures obtained during radiator testing. The project work was developed with and introduction where I described the elements of the test room and standard of HRN EN 442-2. The results of the measurements were analyzed according to the norm and later gave additional comparison with method from the VDI Heat Atlas. In the end I did parametric analysis and made recommendations to improve the structure in order to increase heating output. At very last there is a comparison of surface temperature of the walls in convector and radiator mode.
