Doseganje temperaturnega ugodja v prostoru z regulacijo hladilne moči ventilatorskega konvektorja

Franetič, Matej (author), Stritih, Uroš (mentor)

Raziskovali smo vpliv načina regulacije hladilne moči na temperaturno ugodje v prostoru in na delovanje sistema za hlajenje. Na novo postavljeni progi za hlajenje in ogrevanje smo testirali razliko med zvezno in dvostopenjsko regulacijo temperature. Želeli smo ugotoviti, kakšno je nihanje temperature prostora in potreben pretok za izbrano regulacijo sistema. Na rezultatih meritev smo pokazali boljše specifikacije zvezne regulacije tako iz vidika prihrankov na sistemu, kot iz vidika temperaturnega ugodja v prostoru. Pretok se je zmanjšal s PID regulacijo zaradi manjšega nihanja sistema. Prikazali smo vpliv notranjih toplotnih dobitkov na regulacijo in stabilnost sistema.

• Title: Achieving temperature comfort in the room by regulating the cooling power of fan coil

Abstract

We researched the influence of the method of cooling power regulation on the room comfort and the operation of the cooling system. We tested the difference between continuous and two-stage temperature control on the newly installed cooling and heating line. We wanted to see the fluctuation of the room temperature and the required flow for the selected system control. The results of the measurements showed better specifications of continuous regulation both in terms of savings on the system and in terms of temperature comfort in the room. The flow was reduced with PID control, due to less system oscillation. We have shown the influence of internal heat gains on the regulation and stability of the system.
