Abstract

Obzirom na temperature okoline zimi i ljeti, u ovom radu se na temelju dopuštenih temperaturnih raspona za siguran rad pojedinih komponenti odredilo koju rashladnu/grijaću opremu treba ugraditi u kućište prve hrvatske punionice vodika instalirane na Fakultetu strojarstva i brodogradnje Zagrebu, osmišljene kao samostalan PV-H2 sustav. Opisan je princip rada punionice i uređaja od kojih se sastoji, te sama konstrukcija. Kako bi se odabralo najbolje tehnološko rješenje projekta upravljanja toplinom, a koje će održavati optimalnu temperaturu unutar kućišta punionice po zimi i ljeti, provedena je detaljna analiza termodinamičkih parametara komponenata sustava. Odabrana je izolacija kućišta, vrsta rashladnih jedinica i grijača pomoću normi HRN EN 12831 i VDI 2078, te režim rada sustava grijanja i hlađenja temeljen na unutarnjoj temperaturi zraka u kućištu. Izračunate su godišnja potrebna toplinska energija za grijanje i hlađenje prema normi HRN EN ISO 13790. Na kraju je provedena analiza dobivenih rezultata proračuna i ukupne potrošnje energije punionice vodika.

Abstract (english)

Regarding to environmental temperature during winter and summer months, and based on allowed temperature range for safe operation of components, in this work it was defined both cooling and heating equipment needed to be installed in the housing of first Croatian hydrogen refuelling station installed at the Faculty of Mechanical Engineering and Naval Architecture in Zagreb that was designed as autonomous PV-H2 system. In order to improve the energy efficiency of the first Croatian hydrogen refuelling station installed at the Faculty of Mechanical Engineering and Naval Architecture, designed as a stand-alone PV-H2 system, an optimal thermal management strategy was proposed. First chapter, after introducing heat management basics, begins with an explanation of refuelling station operating principle and the equipment of which it consists, ending with the description of construction itself. In order to select the best technological solution for thermal management project, which will maintain optimal temperature inside of housing in winter and summer, a detailed analysis of the system components thermodynamic parameters was performed. Insulation, type of cooling units and heaters are selected according to the HRN EN 12831 and VDI 2078 standards, while regime of the heating and cooling system is selected based on the station indoor air temperature. The annual required heating and cooling energy is calculated according to HRN EN ISO 13790 standard. To conclude, an analysis of the calculation results and the total energy consumption of the hydrogen refuelling station were performed.
