某大型体育馆空调冷热源方案及能耗分析对比

Comparison and Analysis of Cooling and Heating Source Schemes and Energy Consumption for Air Conditioning in a Large Stadium

该文依托武汉某大型体育建筑项目,根据体育场馆建筑的负荷特性,分析了采用变频螺杆式冷水机组制冷、燃气锅炉制热和采用双冷热泵与多联机系统相结合的分散复合式冷热源方案的能源利用率,通过实际设计中的数据对比分析,发现采用分散复合式冷热源的一次能源利用率更高,更适用于大型体育场馆的空调冷热源系统方案。

This paper relies on a large-scale sports architecture project in Wuhan.Based on the load characteristics of sports stadium buildings,it analyzes the energy utilization efficiency of two schemes:one utilizing variable-frequency screw chillers for cooling and gas-fired boilers for heating,and the other employing a decentralized hybrid cooling and heating source scheme that combines dual-cooling heat pumps with multi-split systems.Through a comparative analysis of data from actual design,it is found that the decentralized hybrid cooling and heating source scheme achieves a higher primary energy utilization ratio,making it more suitable for the air conditioning cooling and heating source system of large stadiums.
