Apstrakt

U radu je prikazana termodinamička (energijska i eksergijska) analiza rada četiri različita sistema toplotnih pumpi: voda-voda, voda-vazduh, vazduh-voda i vazduh-vazduh, koji se koriste za potrebe grejanja. Pretpostavljeno je da su snage grejanja sve četiri toplotne pumpe međusobno jednake, kao i temperaturni režim rada grejnog sistema. U zavisnosti od uticajnih parametara, i to temperature toplotnog izvora i promene temperature toplotnog izvora na isparivaču toplotne pumpe, analizirane su promene koeficijenta grejanja i eksergijskog stepena korisnosti toplotnih pumpi. Ustanovljeno je da toplotne pumpe sa podzemnom vodom kao izvorom toplote imaju veći COP i eksergijski stepen korisnosti od toplotnih pumpi sa okolnim vazduhom kao izvorom toplote. Sprovedena analiza pruža smernice pri odabiru odgovarajuće toplotne pumpe i optimizaciji njenog rada.
