摘　　要：对于通风空调系统中输送非标准空气的非标准管道,传统的摩擦阻力计算方法比较繁琐,而且已有文献对于比摩阻修正方法的表述不具体,易导致不合理的修正。本文通过理论分析和实例计算比较,明确通风空调管道比摩阻修正原则,提出一种基于风机选型的管道比摩阻合理修正方法,该方法有助于设计人员理解比摩阻修正的原理,提高计算结果的可靠性,提升工作效率。For the non-standard pipe conveying non-standard air in the ventilation and air-conditioning system,the traditional method to calculate the friction resistance is complicated.The description of specific frictional resistance(SFR)correction method in existing literatures is not specific,which is easy to lead to unreasonable correction.Through theoretical analysis and practical calculation comparison,the correction principle of SFR of ventilation and air-conditioning pipelines is clarified,and a reasonable correction method of SFR based on fan selection is proposed.It is helpful for designers to understand the principle of SFR correction,and improve the reliability of calculation results and the work efficiency.
