Joule-Tesla Bridge

用于加热和冷却的电力和天然气形式的能源消耗是产生绿色家用气体的最大贡献者之一。太阳热能的应用是减少化石燃料消耗的最有前景的方法之一，该建议的重点是潜热热储存，这是目前国际上的一个关键优先事项，与储存材料的相变（相变材料）有关，通常从固相变为液相，反之亦然。LHTES系统显著提高了太阳能热能利用的效率和可行性。所有LHTES的主要缺点是PCM的低导热性。该项目的目标是通过理论和实验研究开发新型LHTES系统，用于蓄热和蓄冷，该系统使用创新的主动控制方法来提高PCM的导热率。该方法将发展用于制备具有所需磁性的铁磁性纵向纳米棒，然后形成纳米棒/有机分子胶体，以调节胶体体系的平均密度与PCM的密度，从而使纳米棒均匀地悬浮在PCM中，避免PCM/纳米棒分离。铁磁纳米棒胶体系统将被添加到PCM中，LHTES将配备一个阵列。这些铁磁纳米棒形成所产生的磁场，以在空间和时间上使PCM中的铁磁纳米棒与PCM中的最高温度梯度对准。纳米棒的排列将在所需方向上急剧增加PCM中的热导率。LHTES中导热性的主动电磁控制由智能控制单元管理。用于电磁控制的电力将在当地使用光伏系统提供，该光伏系统具有由二次寿命电动汽车电池制成的存储。

Energy consumption in the form of electricity and gas for heating and cooling is one of the biggest contributors to the generation of Green House Gases. The application of solar thermal energy is one of the most prospective ways to reduce the consumption of fossil fuels for these purposes.The focus of this proposal is on Latent Heat Thermal Storage (LHTES), which is currently a key international priority and is connected with a phase transformation of the storage materials (Phase Change Materials - PCMs), typically changing from solid phase to liquid and vice versa. LHTES systems significantly improve the efficiency and viability of solar thermal energy utilisation. The main disadvantage of all LHTES is the low thermal conductivity of PCMs. The project aim is to develop, through theoretical and experimental research, novel LHTES systems for heat and cold accumulation, which use an innovative active control method to improve the thermal conductivity of PCM. The method will be developed for the production of ferromagnetic longitudinal nanorods with required magnetic properties, and then nanorod/organic molecules colloid will be formed to tune the average density of the colloid system with the PCM's density so as to homogeneously suspend nanorods in the PCM and avoid the PCM/nanorods separation. The ferromagnetic nanorod colloid system will be added to the PCM, and the LHTES will be equipped with an array of solenoids. These solenoids form the resulting magnetic field to align in space and time the ferromagnetic nanorods in the PCM with the highest temperature gradient in the PCM. The alignment of the nanorods will sharply increase the thermal conductivity in the PCM in the required direction. The active electromagnetic control of thermal conductivity in the LHTES is governed by a smart control unit. The electricity for the electromagnetic governing will be provided locally using a PV system with storage made of second-life Electrical Vehicle batteries.
