Process Design and Performance Analysis of an Indirect Liquid-cooling System based on Mechanical Vapor Recompression(MVR)Falling Film Evaporation for Energy Storage Battery
The process design of energy storage battery cooling system is crucial for ensuring heat dissipa-tion 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 stor-age 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 sys-tem and a conventional air conditioning refrigeration system,focusing on energy consumption and eco-nomic feasibility,under a cooling load of 210 kW.Meanwhile,the impact of key thermodynamic parame-ters 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 ener-gy storage battery cooling systems.
