Abstract

Na osnovu dostupnih podataka o potrošnji energije, zgrade se ubrajaju u najveće potrošače energije u svijetu. Čest slučaj u modernim poslovnim zgradama je istovremeno
korištenje elemenata za grijanje, odnosno hlađenje, i prisilnu ventilaciju kako bi se osigurali željeni zahtjevi krajnjih korisnika, odnosno zaposlenika.
U ovom radu razmatra se konfiguracija dvije klimatizirane zone u zgradi u kojima
postoje elementi za grijanje, odnosno hlađenje, te dotok kondicioniranog zraka pripremljenog u klima komori. Za opisanu konfiguraciju zona izveden je matematički
model koji opisuje dinamičko ponašanje temperature i koncentracije CO2 u zoni. Potom
je razvijen algoritam optimalnog upravljanja klimatizacijom prostorija koji koristi
sekvencijalne postupke linearizacije i minimizira trošak održavanja zahtijevanih uvjeta
temperature i koncentracije CO2 u zonama na odgovarajućem vremenskom prozoru u
budućnosti. Sustav optimalnog upravljanja implementiran je po principu pomičnog
horizonta i testiran je u Matlab/Simulink okruženju.

Abstract (english)

Based on the available consumption data buildings are one of the largest energy consumers in the world. The use of heating, cooling and forced ventilation elements, at the same time, is often the case in modern office buildings to provide desired conditions
for the end-users.
Configuration of two building zones equipped with heating and cooling elements and inflow of air prepared in air handling unit is considered in this paper. Mathematical model which describes dynamical temperature and CO2 concentration behaviour in building zone is derived for the previously described building zone configuration. Afterwards,
optimal control algorithm for the air-conditioning of building zone, which uses sequential linearisation and minimizes total cost for the maintenance of required temperature and CO2 conditions at the appropriate time-frame in the future, was developed. Optimal control system which uses receding horizon principle has been implemented and tested in Matlab/Simulink environment.
