摘　　要：为提高能源利用效率、降低碳排放量,设计了一种将自然冷源利用于压缩空气冷却干燥系统的新型压缩空气处理系统,挑选5个代表城市进行自然冷源利用可行性和新系统在各城市的热力性能分析,并将其与传统压缩空气冷却干燥系统性能进行对比。结果表明:哈尔滨、天津等寒冷地区自然冷源可利用率均超过40%,利用自然冷源的可行性更具优势;以哈尔滨为例,通过自然冷源与制冷系统合理配合,平均每台系统全年能耗可减少260 kW·h,碳排放量减少70.72 kg,二氧化碳排放量减少259.22 kg,结果显示利用自然冷源的压缩空气干燥系统具有显著的能源效益。To enhance energy utilization efficiency and reduce carbon emissions,a novel compressed air treatment system has been devised that harnesses natural cold sources for air compression cooling and drying,five representative cities were selected to evaluate the feasibility of natural cold source utilization,and the thermal performance analysis of the new system in each city was conducted.This analysis was then compared to the performance of traditional compressed air cooling and drying systems.The results indicate that in cold regions such as Harbin and Tianjin,the utilization rate of natural cold sources exceeds 40%,demonstrating a clear advantage in harnessing these natural cold sources.Taking Harbin as an example,when natural cold sources are appropriately integrated with the refrigeration system,the average annual energy consumption of each system can be reduced by 260 kW·h,resulting in a reduction of 70.72 kg in carbon emissions and 259.22 kg in carbon dioxide emissions.The results show that the compressed air drying system using natural cold source has remarkable energy efficiency.
