摘　　要：通过对GB/T 14294-2008《组合式空调机组》中声压级噪声限值的讨论,提出了噪声限值的计算方法,用于计算高静压、大风量下组合式空调机组的噪声限值;结合EN 1886-2007,比较了我国标准和欧洲标准中空调机组漏风率的判定指标,并给出了漏风率按机组表面积及机组设计静压进行修正的优化建议。Through the discussion on the limit of sound pressure level in GB/T 14294-2008 Central-station air handling units, proposes a reasonable calculation method of noise limit, which provides a reference for deriving the noise limit at high static pressure and large air rate. In addition, in combination with EN 1886-2007, compares the judgment criteria of the air leakage rate and provides the optimization suggestion of the correct air leakage rate according to the surface area and the design static pressure of the unit.
