Development and feedback from students on innovative Nextion interface–Arduino platform for measuring the performance of heat pump system

Abstract University courses in thermodynamics often include practical work (PW) on thermal transfer systems. However, measurements and calculations using conventional equipment can be difficult and inaccurate. To solve this problem, we have developed an innovative measurement platform that integrates a Nextion interface, an Arduino board and various types of sensors. This platform aims to improve the accuracy and performance of the acquisition system. Experimental tests of the platform have demonstrated its ability to provide accurate data on temperatures, pressures, energy consumption, thermal power generated, electrical power, ideal efficiency and coefficient of performance (COP). When tested with a group of university students, the platform proved reliable and useful, validating the predicted thermodynamic processes and stabilizing the ideal efficiency and COP under specific operating conditions. The students also expressed their satisfaction with the pedagogical improvements made. This platform is therefore proving to be a valuable tool for the PW of university students. It makes possible to evaluate the performance of heat pumps in real-time and to optimize thermal management for future work.
