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