Abstract

Spremnici topline imaju ključnu ulogu kod djelotvornog korištenja topline u proizvodnim procesima. To su uređaji koji privremeno pohranjuju toplinu pri visokim i niskim temperaturama i na taj način smanjuju potrebu za vanjskim izvorima grijanja ili hlađenja koji su nužni u proizvodnim procesima. Najčešće korišteni su spremnici tople vode. Kod procesa proizvodnje piva u upotrebi su spremnici za toplu i hladnu vodu, vrlo često sa više zona grijanja ili hlađenja kako bi se zadovoljio temperaturni režim proizvodnje piva. Kod pivovara koji rade sa smanjenim kapacitetom dolazi do gubitka topline prilikom prekida rada od više dana što utječe na veću potrošnju vanjskih energenata. Cilj rada je analiza spremnika topline u lokalnoj pivovari, srednjeg kapaciteta i mogućnosti povećanja njegove djelotvornosti.

Abstract (english)

Thermal energy storage systems are key to efficient heat utilization in industrial processes. This technology is used for temporary storage of heat at high and low temperatures thus reducing the need for external sources of heating or cooling that are necessary in manufacturing processes. The most commonly used heat storage systems are hot water tanks. In beer production, both hot and cold water tanks are utilized, often with multiple heating and cooling zones in order to provide adequate temperature conditions. Brewhouses which operate at a reduced capacity have longer shutdown periods and therefore suffer heat losses that result in greater external energy consumption. The aim of this paper is to analyze a heat storage of a medium capacity, local brewery and the possibilities of increasing its efficiency.
