写字楼楼体不见一台外挂机,却能让1.7万平方米办公区域保持凉爽,这是青岛市南区福州南路的中天恒大 厦,作为全国首个既有建筑光储直柔项目,依托磁悬浮制冷黑科技,实现了整栋写字楼的"集中供冷"。青岛 能源集团数据显示,目前青岛市已有19处场所采用"集中供冷"模式,通过海水源热泵、地源热泵、磁悬浮 冷水机组等新能源多元技术路径,实现了高效节能与低碳减排的双重突破。 文/片赵波青岛报道 光储直柔+磁悬浮: "无空调外机"清凉样本 "整栋大厦没安一台空调,却比传统中央空调更舒适。"青岛能源热电集团第三热力生产与安全服务科副 科长申甲介绍,这座建于2000年的大厦,2023年完成用能系统升级,成为清华大学江亿院士光储直柔示范项 目,搭载直流磁悬浮冷水机组,实现"光伏发电-直流供能-水蓄冷调节"全链条绿色供冷,项目实现了柔性用 能,通过数字平台实时匹配光伏出力与负荷需求,动态调整冷站运行模式,夏季高峰时段减少电网依赖度超 50%。 在中天恒大厦的楼顶,记者看到,屋顶布满了光伏板,这些分布式光伏年发电量达15.7万度,覆盖建筑40%的 空调供冷用电,直流配电系统直接驱动设备,减少交直流转换损耗,综合能效提升14%,在大楼内, ...

Core Viewpoint - The article highlights the development of the Haikou Jiangdong New District, focusing on the implementation of a "cool city" design that incorporates ecological and human-centered features to enhance urban living conditions and reduce energy consumption. Group 1: Urban Design and Features - The Jiangdong New District emphasizes an "ecological headquarters CBD" positioning, utilizing rooftop gardens, terrace gardens, and vertical greening to increase green coverage and create a "cool microclimate" in the area [1] - The Jiangdong Tiandi project incorporates the "cool city" concept from Singapore, featuring design elements such as recessed corridors, sunshade membranes, and shaded walkways to enhance the cooling experience for residents and visitors [2] Group 2: Energy Efficiency and Sustainability - The Jiangdong Development Building employs centralized cooling systems that store energy during low electricity demand at night, producing ice for daytime cooling, significantly reducing regional energy consumption and mitigating the urban heat island effect [3] - The estimated annual carbon reduction from the centralized cooling approach in the Jiangdong New District headquarters economic zone is projected to reach 58,000 tons [3]
