摘　　要：核电站用空气处理机组因须兼顾较高的结构强度要求与性能要求,机组的气密性通常高于国家标准GB/T14294—2008《组合式空调机组》规定的漏风率。本文通过对某核电站空调机组的结构进行改进,并进行试验验证,将箱体漏风率从2.6%降低至0.9%,最终满足某核电站对箱体漏风率的要求。The air tightness requirement of air handling unit for nuclear power plant is usually higher than the air leakage rate stated in the national standard GB/T 14294-2008 Central-station air handling units, because of both high structural strength and perform- ance requirement. By the structure improvement of the air handling unit for one nuclear power plant and test verification, the air leakage rate of the box body is reduced from 2.6% to 0.9%, which meets the requirement of air leakage rate for one nuclear power plant.
