Abstract

Ovaj diplomski rad prikazuje projektno rješenje sustava sezonskog grijanja i hlađenja te cjelogodišnje ventilacije stambeno-poslovne zgrade smještene u Osijeku. Kao rješenje za grijanje i hlađenje zraka u prostorijama, koristi se dvocijevni vodeni sustav parapetnih ventilokonvektora. Priprema ogrjevne i rashladne vode vrši se centralno u dizalici topline zrak-voda, odabranoj prema potrebnim kapacitetima za grijanje i hlađenje prostorija. Za proračun toplinskih opterećenja korištene su norme HRN EN 12831 za zimu i VDI 2078 za ljeto. Sustav mehaničke ventilacije izveden je kao sustav promjenjivog volumenskog protoka zraka gdje se protok regulira preko koncentracije ugljikovog dioksid u prostorijama. Priprema kondicioniranog zraka vrši se u centralnoj jedinici za pripremu zraka i kanalima razvodi do istrujnih i usisnih otvora. Za proračun ventilacijskih potreba korišteno je nekoliko metoda te je odabran maksimalni iznos potrebnog protoka zraka. Rad sadrži provedene proračune potrebne za dimenzioniranje opreme sustava i tehničke crteže koji prikazuju raspored komponenata te njihovu regulaciju i spajanje.

Abstract (english)

This master thesis presents the project solution of the seasonal heating and cooling system and the all year round ventilation of residential-business building located in Osijek. As a solution for heating and cooling room air, a two-pipe water system of parapet fan coil units is used. The preparation of heating and cooling water is done centrally in the air to water heat pump, selected according to the required capacities for space heating and cooling. Norms HRN EN 12831 for winter and VDI 2078 for summer are used to calculate heat loads. The mechanical ventilation system is designed as a system of variable volume air flow where the flow is regulated through the concentration of carbon dioxide in the rooms. The preparation of conditioned air is performed in the central air preparation unit and distributed through ducts to the outlet and suction openings. Several methods are used to calculate the ventilation needs and the maximum amount of required air flow is chosen. The paper contains the performed calculations necessary for the sizing of the system equipment and technical drawings showing the arrangement of the components and their control and connection.
