地下蓄热体新风降温节能技术的研究与应用

Study and application of fresh air cooling technology using earth heat retainers

介绍了该技术在上海世博轴的工程应用情况。研究表明地下蓄热体可以用于新风降温,且冷却能力随风量增大而提高。然而系统能效分析表明并非风量越大越好,部分新风降温系统具有更高的效率,需要根据工程的具体情况进行优化设计。

Presents the application of the technology in Expo Axis, Shanghai. The research result shows that the earth heat retainer can be used to cooling fresh air, and that the larger the air flow rate, the greater the cooling capacity is. However, the energy efficiency analysis indicates that the system with part fresh air cooled by earth heat retainer has higher efficiency and it is necessary to do optimizing design for each actual projects.
