Sažetak
Za razvijanje efikasnih sistema grejanja, obezbeđujućih normativne uslove u prostorijama pri minimalnoj potrošnji energije, moramo da znamo raspodelu radiacionih i konvektivnih flukseva toplote od grejnih tela. Razrađen je i opisan metod istraživanja. Izučavana su grejna tela (konvektor radijator) sistema za grejanje na vodu. Prikazani su rezultati merenja toplotnog fluksa grejnih tela. Opredeljene su konvektivne i radiacione komponente toplotnog fluksa grejnih tela.
Abstract
The knowledge of radiant and convective heat flows distribution from heating appliances is required for a development of an efficient heating systems maintaining necessary conditions in rooms at the lowest energy requirements. The study method is developed and provided. The heating appliances of water heating system (convection heater and radiator) are studied. The results of heating appliances heat flow measurements are given. Radiant and convective components of heating appliances heat flow are determined.
