摘要

针对制氢工厂的能源需求，设计了一套集成电解槽余热回收的能源自洽系统。该系统采用三级梯级潜热储能(CTES)装置，回收利用电解槽产生的余热，为吸收式制冷及生活热水供应提供稳定热源，从而实现制氢过程中的冷热联供。在材料层面，选用3种以石蜡为基材的复合相变材料，并测试其热物性参数；通过Ansys Fluent软件对CTES单元的热响应特性进行数值模拟，并基于TRNSYS动态仿真平台开展系统运行特性分析。系统集成CTES前后的对比结果表明，系统运行稳定，制冷量满足需求，热泵COP偏差小于5%。经济性上，CTES的全生命周期成本为534万元，较单级系统降低明显，动态投资回收期仅3.5年，且采用复合相变材料使储能单元投资下降约53%，显著提升了系统能效与经济竞争力。该系统成功实现了制氢过程中余热的梯级回收与冷热联供的结合，为工业领域提供了一种高效、经济且稳定的能源自洽解决方案，显著提升了氢能生产的综合能效与经济竞争力。

Abstract

The present study introduces a self-consistent energy system designed to recover waste heat from electrolytic cells

thereby addressing the energy demands of hydrogen production plants. The system incorporates a three-stage latent heat storage (CTES) device that captures and utilizes waste heat generated by the electrolytic cell

providing a reliable heat source for absorption refrigeration and domestic hot water supply. This integration facilitates the combined supply of cooling and heating during hydrogen production. At the material level

three composite phase change materials (CPCMs) based on paraffin were selected

and the thermal physical properties were tested. The thermal response characteristics of the CTES unit were simulated using Ansys Fluent software

and the operational performance of the system were analyzed based on the TRNSYS dynamic simulation platform. Comparative results before and after CTES integration reveal the stable systematic operation

with cooling capacity meeting demand and the coefficient of performance deviation of the heat pump being less than 5%. Economically

the total life cycle cost of the CTES is ¥5.34 million

significantly lower than that of a single-stage system

with a dynamic payback period of only 3.5 years. In addition

the application of CPCMs has reduced investment in energy storage units by approximately 53%

significantly improving the energy efficiency and economic viability of the system. Overall

this system effectively integrates cascade waste heat recovery from the hydrogen production process with combined cooling and heating supply

providing an efficient

cost-effective

and stable energy-autonomous solution for the industrial sector. This approach significantly enhances the overall energy efficiency and economic competitiveness of hydrogen production.
