20.500.12556/DKUM-77130 Numerična simulacija temperaturnih razmer v zalogovniku tople vode v hali IPC diplomsko delo Numeric simulation of temperature conditions in a hot water tank inside IPC hall V diplomskem delu smo reševali problem mešanja vode v zalogovniku, ki povzroči prenizko temperaturno razliko med zgornjim in spodnjim delom zalogovnika ter s tem onemogoča avtomatski preklop smeri ogrevanja. Opisali smo stanje zalogovnika in ogrevalnega sistema. Z meritvami smo določili potrebne pogoje za izvedbo numerične simulacije temperaturnih razmer v zalogovniku. Rezultate simulacije smo primerjali z dejanskim stanjem, nato pa smo izvedli še simulacije, v katerih smo upoštevali predlagane rešitve, ki so obsegale optimizacijo pretoka in konstrukcijske rešitve. V nadaljevanju smo predstavili rezultate simulacij in ugotovili, katera izmed rešitev je najprimernejša za implementacijo. The problem of cold and hot water mixing was occurring inside a hot water tank. The problem caused insufficient temperature conditions which led to incorrect functioning of the heating system. We described the state of the hot water tank and the heating system. We conducted measurements to determine the correct boundary conditions for a numeric simulation of the temperature conditions. The results were compared to the actual conditions. We then performed simulations with suggested solutions, which consisted of flow optimizations and construction changes. In the end we presented the simulation results and concluded which of the solutions was the most suitable for implementing. numerična simulacija zalogovnik tople vode temperaturne razmere numeric simulation hot water tank temperature conditions true true false [D.
