Abstract

Ovaj diplomski rad obuhvaća projektno rješenje sustava grijanja, hlađenja i ventilacije objekta koji se sastoji od uredskih prostora i proizvodne hale. Objekt se nalazi na području grada Ludbrega. Kao rješenje za grijanje i hlađenje uredskih prostora i proizvodne hale odabran je dvocijevni vodeni sustav grijanja i hlađenja pomoću ventilokonvektora sa prekretanjem između grijanja i hlađenja. Potrebna količina vanjskog zraka za uredske prostore i proizvodnu halu ubacuje se pomoću odvojenih sustava niskotlačne mehaničke ventilacije. Za potrebe grijanja odabran je kondenzacijski kotao, a za potrebe hlađenja rashladnik vode. Projektno rješenje obuhvaća tehno-ekonomsku analizu tri moguća sustava grijanja, hlađenja i ventilacije te odabir optimalnog na temelju investicijskih i pogonskih troškova. U radu se nalazi kompletan termodinamički proračun toplinskih gubitaka i dobitaka, hidraulički proračun i proračun zračnih kanala. Grafički je prikazana dispozicija cijevne mreže, zračnih kanala i funkcionalna shema spajanja i regulacije.

Abstract (english)

This diploma thesis contains project decision for thermotechnical system of heating, cooling and ventilation of the object with office spaces and production hall. The object is situated in the area of city of Ludbreg. Twin-tube water heating and cooling system supported by fan coil with cooling-heating reversing option was chosen for cooling and heating of the object. The required amount of fresh air is inserted into offices and hall through separated system of low-pressure mechanical ventilation. Condensable boiler was chosen for heating, and water cooler for cooling. Project solution contains techno-economical analysis of three different HVAC systems and the optimal has been determined due its investment and operating costs. The paper covers the complete calculations of heating and cooling peak load, hydraulic calculations and calculation of air channels. Annex contains graphic illustrations of the arrangement od the equipment, distribution of air channels and the pipeline array and the schematic for connection and regulation of the system.
