【摘要】 储能电池冷却系统的设计在确保其散热效果、能效优化以及安全稳定运行方面至关重要。本文旨在提出一种新型的储能电池散热方式，以实现储能电池冷却系统的高效益和低能耗目标。基于机械蒸汽再压缩(MVR)降膜蒸发原理，首先设计了MVR降膜式储能电池间接液冷系统的具体流程形式，并利用Aspen Plus软件对系统进行仿真计算；随后将系统与冷却负荷210 kW的常规空调制冷系统实例进行了能耗和经济性对比分析，并探讨了关键热力参数对系统性能的影响。结果表明，该系统较于常规一级能效制冷系统节能效果明显，可达到77.04%;提高冷却温度和降低压缩温升有助于进一步降低系统能耗；在210 kW冷却负荷条件下，MVR降膜式间接液冷系统投资回收期仅为2个月，经济效益较为显著。研究表明MVR降膜蒸发技术在储能电池冷却系统中展现出潜在的节能和经济效益优势。更多还原

【Abstract】 The process design of energy storage battery cooling system is crucial for ensuring heat dissipation effectiveness, energy efficiency optimization, and safe operation. To achieve high efficiency and low energy consumption in cooling system, this paper aims to propose a novel cooling scheme for energy storage battery. An MVR falling film evaporation-based indirect liquid-cooling system is designed and simulated using Aspen Plus software. Subsequently, a comparison is conducted between the proposed system and a conventional air conditioning refrigeration system, focusing on energy consumption and economic feasibility, under a cooling load of 210 kW. Meanwhile, the impact of key thermodynamic parameters on system performance is analyzed. The results show that the proposed system achieves considerable energy savings compared to the conventional first-level refrigeration system, with savings of up to 77.04%. Higher cooling temperature or lower compression temperature rise can further reduce the energy consumption of the proposed system. With a cooling load of 210 kW, the investment payback period for the proposed system is only 2 months, indicating significant economic benefits. This study highlights the potential of MVR falling film evaporation technology for substantial energy and economic benefits in energy storage battery cooling systems.更多还原
