Abstract

Mjerni podaci prikupljeni su u okviru sustava za grijanje i hlađenje na 9. katu C
zgrade Fakulteta elektrotehnike i računarstva u Zagrebu u periodu od mjesec dana. Provedena je identifikacija ventilokonvektorskog modela u stacionarnom stanju temperature
izlaznog zraka u prostoriji za svaku brzinu ventilokonvektora posebno. Tražila se
ovisnost temperature izlaznog zraka u stacionarnom stanju o temperaturi zraka u sobi,
protoku na katnom razvodu te o ulaznoj temperaturi medija. Identifikacija stacionarnog
stanja vršena je uz pomoć neuronskih mreža, a modeliranje dinamike korištenjem
filtra prvog reda. Konačno dobiveni Hammerstein model može se koristiti kao osnova
za upravljanje čitavim ventilokonvektorskim sustavom.

Abstract (english)

This work was based on the identification of the steady state model of one fan coil
unit that is present in the HVAC system of the 9th floor of the C building of the Faculty
of electrical engineering and computing, University of Zagreb. The model tried to map
the connection and dependence of the output fan coil air temperature to the room air
temperature, medium flow and input medium temperature. The identification was performed
using neural networks and first-order discrete filter on the basis of samples that
were recorded in the HVAC system over the period of a month. Obtained Hammerstein
class model can be used as a basis for the control of the entire fan coil system.
