Desenvolvimento de um trocador de calor didático baseado em Arduino

Abstract

The development of educational modules allows the application of their theoretical knowledge facilitating their understanding and contributing to the search for improvements to the processes. Therefore, this study aimed to develop a didactic heat exchanger based on the Arduino platform that would enable the understanding of the functioning of the same and its efficiency. For its development we used a double exchanger tube with countercurrent flow with four DS18B20 temperature sensors fitted at inputs and outputs of flows. The sensors were linked to the Arduino platform which in turn was connected to the computer. Through the platform was made to determine the fixed variables, as follows area, flow and heat capacity of the fluid in question. The experimental test was performed using hot water and cold water and two pumps with flow rates determined manually. The results showed that the system is more efficient when subjected to higher temperature associated with a less flow. It can be concluded that the system developed is an alternative for studies of its operation and verification purposes of the variables that can affect heat transfer.
