摘要 针对化工生产低温冷冻站运行费用过高和供水温度不稳定的问题，建议采用工艺冷源用共晶盐低温动态蓄冷系统。以某医药化工厂低温冷冻站为例，分析、比较了低温蓄冷系统和常规冷冻系统的能耗和经济性。 关键词 低温蓄冷 共晶盐 工艺冷源 经济性 Economic analysis of process cold source with the eutectic salt low temperature dynamic cool storage system By Deng Yuyan，Ding Lixing and Xiao Peng Abstract Proposes adopting the system for solving the problems of overhigh operating costs and unstable supply water temperature in the low temperature refrigeration station for chemical production. Taking a pharmaceutical chemical plant as an example, analyses and compares the energy consumption and economic efficiency of the low temperature dynamic cool storage system and the conventional refrigeration systems. Keywords low temperature cool storage， eutectic salt， process cold source， economic efficiency
