多热效应被定义为由外部电场或磁场引起的多铁性材料中的绝热可逆温度变化，它于2012年首次在理论上提出。多铁性材料中的多热效应，以及单铁性材料中的其他类似热效应，如磁热、弹热、压热和电热，由于其在固态制冷中的潜在商业化，一直是许多研究的焦点。在这篇简短的通讯文章中，我们研究了固态加热应用中的多热量效应的热力学。提出并实现了一种可能的热力学多热量加热循环，以估计已知电热系统的固态加热效果。这项工作提供了一个路径，以实现热量和多热量的影响，以有效的加热系统，我们提供了一个理论估计的上限，可实现的温度变化的多热量的冷却或加热效果。
The multicaloric effect is defined as the adiabatic reversible temperature change in multiferroic materials induced by the application of an external electric or magnetic field, and it was first theoretically proposed in 2012. The multicaloric effects in multiferroics, as well as other similar caloric effects in single ferroics, such as magnetocaloric, elastocaloric, barocaloric, and electrocaloric, have been the focus of much research due to their potential commercialization in solid-state refrigeration. In this short communication article, we examine the thermodynamics of the multicaloric effect for solid-state heating applications. A possible thermodynamic multicaloric heating cycle is proposed and then implemented to estimate the solid-state heating effect for a known electrocaloric system. This work offers a path to implementing caloric and multicaloric effects to efficient heating systems, and we offer a theoretical estimate of the upper limit of the temperature change achievable in a multicaloric cooling or heating effect.
