Abstract
Uniformity of realized heating source temperature field is a real index of its setted requirements in the controlled piglets zone. Heating process is realized by convection+radiation. Influence of total heat transmission on piglets body is described by resultant dry air temperature. Thermoinsulation of passive heating panel surface results with energy saving of 9,44%. In combination with arch chamber 10 cm over active surface, insulated concrete panel increased energy saving of 21,72%. Uniformity stage of realized temperature field is increased too. This was result of accumulative heat recurrence influence. Put down on the surface of panel, arch chamber increased energy saving about 15,76%.
Sažetak
Uniformnost ostvarenog temperaturnog polja toplotnog izvora, realan je pokazatelj realizacije njemu postavljenih zahteva u kontrolisanom prostoru za uzgoj prasadi. Zagrevanje prasadi na podnom panelu obavlja se prenosom toplote konvekcija+zračenje. Uticaj ukupnog prenosa toplote na telo praseta opisan je rezultantnom temperaturom suvog vazduha. Termoizolovanost pasivne površine grejnog panela rezultira uštedom energije 9,44%. U kombinaciji sa lučnom komorom 10 cm iznad razmenjivačke ravni panela, ovako izolovan panel doprinosi uštedi energije 21,72%. Time je povećana uniformnost ostvarenog temperaturnog polja, kao posledica povratnog zračenja akumulisane toplote u lučnom akumulatoru. Pri spuštenoj komori na razmenjivačku ravan panela ušteda energije porasla jeza 15,67%.
