Simulation Analysis of Airflow Distribution and Evaluation of Energy-Saving Potential for the Air Conditioning System in Large Concert Halls
为了评价大空间建筑气流组织,在满足空调设计要求的情况下,通过对能量有效利用系数定义式进行合理变形简化,得出便于在工程中实施测量的计算公式,采用CFD软件对房间空调的送风进行模拟分析,模拟实际工程的测量值,作为评价空调气流组织的节能潜力的参考依据.按定义式计算得出的气流组织能效有效利用系数为0.924,按模拟测量计算的结果为0.916,两者偏差率为0.87％,简化后的计算公式对计算结果影响很小.
In order to evaluate the air distribution in large-space buildings,when the air distribution meets the air-conditioning design requirements,through reasonable transformation and simplification of the definition formula of the effective energy utilization coefficient,a calculation formula that is convenient for implementation and measurement in engineering is obtained.The CFD software is used to simulate and analyze the air supply of the room air-conditioning,and the measured values of the actual project are simulated as a reference basis for evaluating the energy-saving potential of the air-conditioning air distribution.The effective utilization coefficient of the air-distribution energy efficiency calculated according to the definition formula is 0.924,and the result calculated according to the simulated measurement is 0.916,and the deviation rate between the two is 0.87％.The simplified calculation formula has little influence on the calculation result.
