Modeling of an Elastocaloric Cooling System for Determining Efficiency

When it comes to covering the growing demand for cooling power worldwide, elastocalorics offer an environmentally friendly alternative compressor-based technology. The absence of harmful and flammable coolants makes suitable energy applications such as battery cooling. Initial prototypes elastocaloric systems, which transport heat by means thermal conduction or convection, have already been developed. A particularly promising solution is active pipe (AEH), works with latent transfer evaporation condensation a fluid. This enables fast efficient in compression-based system. In this publication, we present simulation model AEH based on MATLAB-Simulink. showed very good agreement experimental data pertaining maximum temperature span power. Hereby, non-measurable variables efficiency fluxes system are accessible, allows analysis individual losses including dissipation effects material, non-ideal isolation, from material fluid, other parasitic flux losses. total, can be shown that using AEH-approach, optimized achieve up 67% efficiency.
