20.500.12556/RUL-144259 Energijske karakteristike naprav za ogrevanje, hlajenje, klimatizacijo in prezračevanje Energy characteristics of devices for heating, cooling, air conditioning and ventilation Naprave za ogrevanje, hlajenje, klimatizacijo in prezračevanje imajo pri bivalnih stavbah vedno večji pomen. Zelo velik vpliv imajo energijske karakteristike teh naprav. Velik pomen teh naprav je pri novogradnjah in sanacijah starih stavb. Energijske karakteristike naprav smo določili eksperimentalno. Za toplotno oddajo ogrevala smo karakteristiko določili glede na različne vrednosti temperature vode v ogrevalu. Za kotel (kurilno napravo) smo karakteristiko določili po direktni metodi glede na toplotne tokove. Izkoristek oziroma karakteristiko rekuperatorja smo določili glede na različne jakosti ventilatorjev. S PID-regulacijo pa smo določili karakteristiko ventilatorskega konvektorja. Ugotovili smo, da na energijske karakteristike vpliva veliko dejavnikov: različne temperature v ogrevalu, sestava goriva, toplotni tok goriva in ogrevanega medija, moč grelnika v prezračevalni napravi in jakost ventilatorjev ter pravilna izbira členov pri PID-regulaciji. Heating, cooling, air-conditioning and ventilation devices are becoming increasingly important in residential buildings. Energy characteristics of these devices have a very strong effect. These devices are very important in new buildings and in renovation of old buildings. Energy characteristics of the devices were determined experimentally. The characteristic for the heat emission of the heater was determined according to various values of water temperature in the heater. The characteristic for the boiler (the heating device) was determined by the direct method according to the thermal fluxes. Recuperator efficiency or characteristic was determined according to various intensities of the fans. The characteristic of the ventilation convector was determined by PID control. We established that numerous factors influence the energy characteristics: different temperatures in the heater, fuel composition, thermal fluxes of the fuel and of the heated medium, intensity of the heater in the air ventilation system, intensity of the fans, and an adequate choice of parts in PID control. učinkovitost naprav ogrevalo kurilna naprava rekuperator PID-regulacija device efficiency heater heating device recuperator PID control true false false [A.
