Dinamički prenos toplote u zgradama: izbor modela manjeg (nižeg) reda

Apstrakt
Prenos toplote u zgradama može se modelovati toplotnim mrežama, koje predstavljaju energetski bilans u sistemu koga formiraju element zgrade i njegovo okruženje. Kontinualni model se može izraziti kao beskonačan niz diferencijalnih algebarskih jednačina. Beskonačan skup jednačina može se poređati u prikazu prostora stanja i na osnovu toga se može dobiti funkcija prenosa matrice. U pratkično svakoj primeni, ovaj model se mora diskretizovati u prostoru, to jest, red modela se mora smanjiti odabirom konačnog skupa diferencijalnih algebarskih jednačina. Funkcija prenosa matrice može se iskoristiti za dobijanje kriterijuma za određivanje modela manjeg (nižeg) reda, koji se može koristiti za modelovanje tokova prenosa toplote u okviru datih granica preciznosti izmerenih ulaznih i izlaznih vrednosti.
