Apstrakt

Prenos toplote u zidovima može se modelovati toplotnim mrežama, koje predstavljaju energetski bilans u sistemu koga formiraju zid i njegovo okruženje. Kontinualni model se može izraziti kao beskonaÄan niz diferencijalnih algebarskih jednaÄina. BeskonaÄan skup jednaÄina može se poreÄ‘ati u prikazu prostora stanja i na osnovu toga se može dobiti funkcija prenosa matrice. U praktiÄno svakoj primeni, ovaj model se mora diskretizovati u prostoru, to jest, red modela se mora smanjiti odabirom konaÄnog skupa diferencijalnih algebarskih jednaÄina. Funkcija prenosa matrice može se iskoristiti za dobijanje kriterijuma za odreÄ‘ivanje modela manjeg (nižeg) reda, koji se može koristiti za modelovanje tokova prenosa toplote kroz zid izmerenih pomoću meraÄa toplotnog protoka (toplotnog fluksa). Funkcija prenosa, koja se odnosi na toplotni fluks kroz zid, nije potpuno odgovarajuća i korišćenje meraÄa toplotnog fluksa jeste ograniÄeno frekvencijom ulaznog signala.
