风机单位风量耗功率的理论分析和实测研究
Theoretical analysis and site testing of energy consumption per unit air volume for fan transportation
摘要：
节能检测中发现，依据JGJ/T 177—2009计算的风机单位风量耗功率不满足GB 50189—2005的要求。通过理论分析和现场实测，认为两个标准中风机单位风量耗功率计算式的含义相同，但使用前提不同，前者只能在设计选型时使用，后者主要针对空调机组和普通的机械通风系统。不恰当使用计算公式将导致错误结果。
Abstract：
The value of the energy consumption per unit air volume for fan transportation calculated according to JGJ/T 177-2009 do not meet the requirements of GB 50189-2005 during the on-site energy efficiency testing. Based on the theoretical analysis and field testing，considers that the calculation methods of energy consumption per unit air volume for transportation listed in the two standards have the same meaning but with different scopes of applicability, the former is used for design, and the latter is for AHU and mechanical ventilation systems. It will result in wrong result if the methods are improperly used.
