Constant Temperature Mechanism Design and Numerical Simulations fot Reversible Ammonia Batteries

Project Details


Low-grade thermal energy (< 200°C) is a large amount of untapped energy produced by various industrial plants and can also be obtained from geothermal sources. Low-grade thermal energy is widely used in our production and life, including industrial waste heat, geothermal, solar energy and ocean thermal energy. Its reserves are huge and varied, especially for the recycling of industrial waste heat. But due to the lack of efficient and cost-effective recycling methods, low- grade thermal energy is generally not adopted by industry, and consequently forming thermal pollution and causing environmental problems. The effective recovery of low-grade thermal energy is not only conducive to solving the problem of energy depletion, but also beneficial to alleviating environmental pollution problems. This project focuses on the constant temperature mechanism design and analysis for Thermally-Regenerative Ammonia-Based Flow Battery (TRAB) by using of COMSOL Multiphysics. In this research, we will analyze heat transfer parameters of the constant temperature mechanism to achieve the optimal distillation and operating temperature ( 40~80℃) to maintain the operating efficiency and analyze the heat of the module during thermal operation loss,and hope to design the best constant temperature mechanism to improve the efficiency and practicality of Thermally-Regenerative Ammonia-Based Flow Battery.
