Description
In response to the escalating demand for energy-efficient refrigeration, active magnetic refrigeration (AMR) has emerged as a promising solution, with researchers focusing on identifying environmentally friendly solid-state refrigerants. Among various candidates, including Gd and Heusler alloys, the evaluation criteria typically revolve around parameters such as isothermal magnetic entropy change (ΔSM) and adiabatic temperature change (ΔTad). However, the complexities of AMR systems demand a broader assessment, considering factors like thermal conductivity, corrosion resistance, and heat transfer coefficients.
To address this, an in-house AMR system has been developed specifically for testing different magnetic refrigerants. This system is being utilized to evaluate MnxFe5−xSi3 compounds with varying compositions to identify the optimal blend for room-temperature refrigeration. By aligning experimental methodologies with real-world application requirements, this study aims to advance the development of efficient magnetic refrigeration technologies.
