Abstract
U ovom radu napravljen je cjelokupan projekt izvedbe rashladnog sustava supermarketa s ugljik dioksidom kao radnom tvari. U uvodu je opisan ugljik dioksid kao radna tvar te vrste rashladnih procesa sa ugljik dioksidom. Izračunat je potreban toplinski kapacitet za hlađenje prehrambenih proizvoda u komorama i u vitrinama na primjeru supermarketa na području sjeverozapadne Hrvatske. Na temelju izračunatog potrebnog toplinskog kapaciteta, dimenzionirane su komponente rashladnog sustava – isparivača, kompresora i hladnjaka plina. Određen je rashladnih proces sa dva seta kompresora, jedan set za plus režim te jedan za minus režim. Dimenzioniran je cjevovod cijelog rashladnog sustava. Odabrane su potrebne komponente sustava – isparivači, rashladne vitrine, setovi kompresora i hladnjak plina. Cjelokupni rashladni proces je opisan, te su određene točke procesa. Opisan je rad automatske regulacije. Također je opisana izvedba projekta po fazama, od početka do kraja te su navedeni sigurnosni zahtjevi radi korištenja ugljik dioksida kao radne tvari.
Abstract (english)
This thesis presents a thorough project that implements a supermarket cooling system with carbon dioxide as a refrigerant. Introduction describes carbon dioxide as a refrigerant and types of cooling processes with carbon dioxide. Cooling capacity needed for cooling food in cold rooms and refrigerated cabinets is calculated on an example of a supermarket in northwest Croatia. Based on this calculation, components of a cooling system are dimensioned - evaporator, compressor, and gas cooler. Cooling process with two sets of compressors is specified, one set of compressors for the plus regime, one for the minus regime. Pipeline of the whole cooling system is dimensioned. Necessary system components are chosen - evaporators, refrigerated cabinets, compressor sets, and gas cooler. Complete cooling process is described and points of the cooling process are determined. Automatic regulation is described. Likewise, project implementation is described in phases, from beginning to end, and safety requirements are listed, due to using carbon dioxide as a refrigerant.
