Análise do desempenho térmico de trocadores de calor tipo serpentina aplicados em uma cervejaria artesanal

Abstract

The purpose of this research is to analyse the capacity of a coil heat exchanger to reach the heat transfer rates required by the production process of handmade beer at a specific company. There, it is curently used a parallel plate heat exchanger to cool the wort, but there is also a coil heat exchanger used to drop the cold source temperature. At first, the theorical concepts referring to the heat transfer had been related to the case. Then, it was conducted the mapping of the main information referred to the productive process and it was collected the technical specifications of the machinery used for the current cooling system. Using as a benchmark the dimensions of the current heat exchanger, calculations were performed for determining the length of the optimal coil for several hot fluid outflows. Finally, it was concluded that the heat exchanger in question will not provide the heat transfer rates required to the maximum flow rate afforded by the one with parallel plates, used by the company.
