要提出了风机单元(FFU中机箱与风机的集成,简称FU)空气动力全效率的概念与计算方法,基于FFU实验室测试标准IEST-RP-CC036.1测试了FFU的空气动力效率,并根据测试结果计算出FU的空气动力全效率。与实测所得FU空气动力全效率对比发现,在FFU常用面风速0.35m/s~0.45m/s范围内,空气动力全效率的计算值和实测值基本吻合,误差在±5%以内,证明了FU空气动力全效率计算方法的可靠性。
The concept and calculation method of total aerodynamic efficiency of fan unit (integrated chassis and fan in FFU) is proposed. The aerodynamic efficiency of FFU is tested based on FFU laboratory test standard IEST-RP-CC036.1, The test results calculated the aerodynamic efficiency of the FU. Compared with the measured aerodynamic efficiency of FU, it is found that the calculated aerodynamic efficiency coincides with the measured value in the range of 0.35m / s ~ 0.45m / s, and the error is within ± 5% FU aerodynamic full efficiency calculation method of reliability.
