摘要/Abstract

摘要：

在“双碳”目标下，工业蒸汽生产过程迫切需要减少化石燃料燃烧产生的CO₂排放。高温热泵作为潜力巨大的低碳能源转换系统，不仅能够高效制备高温蒸汽，同时可显著降低能耗并减少碳排放。为解决单级高温热泵无法实现大温升这一难题，提出了将高温热泵与储能系统相结合的高效能源解决方案，该耦合系统可以利用储能系统的特性缩小压缩机压比，从而实现极端工况下的高效蒸汽制备；建立了包含能量、㶲、经济及环境效益在内的综合变工况调节模型，通过与常规大温升高温热泵对比，评估了高温热泵耦合储能系统的应用潜力；此外建立了高温热泵耦合储能系统的最优策略模型。结果表明：在单级高温热泵无法有效运行的工况下，耦合储能系统的高温热泵仍能维持工业蒸汽的稳定输出，其性能系数和蒸汽产量分别最低提升了134.3%和461.5%；储能系统存在最优运行策略，只有在变工况条件下合理配置储能系统，才能实现耦合系统性能与经济性的同步提升。

Abstract:

Under the "dual carbon" goals， it is urgent to reduce CO₂ emissions from fossil fuel combustion in the industrial steam production process. High-temperature heat pumps， as highly promising low-carbon energy conversion systems， can not only efficiently produce high-temperature steam but also significantly reduce energy consumption and carbon emissions. To address the challenge that single-stage high-temperature heat pumps cannot achieve large temperature lifts， an efficient energy solution integrating high-temperature heat pumps with energy storage systems was proposed. This coupled system could leverage the characteristics of the energy storage system to reduce the compressor pressure ratio， thereby enabling efficient steam production under extreme operating conditions. Additionally， an integrated regulation model for variable operating conditions including energy， exergy， economic， and environmental benefits was established. Through comparative analysis with conventional high-temperature heat pumps capable of large temperature lifts， the application potential of the high-temperature heat pump coupled with the energy storage system was evaluated. Furthermore， an optimal strategy model for the coupled system was established. The results showed that under operating conditions where single-stage high-temperature heat pumps failed to operate effectively， the high-temperature heat pump coupled with an energy storage system could still maintain stable industrial steam output， with its coefficient of performance and steam production improved by at least 134.3% and 461.5%， respectively. The energy storage system had an optimal operating strategy， and only through rational configuration under variable operating conditions could the coupled system achieve synchronous improvements in performance and economic efficiency.

Key words: "dual carbon" goals, large temperature lift, high-temperature heat pump, energy storage system, strategy optimization, energy quality enhancement technology, low-carbon energy conversion system
