摘　　要：目的　提出空气净化器对甲醛净化效果评价的时间和测定间隔。方法　在 30m3和 1 5m3测试舱中进行自然衰减试验和甲醛去除效果试验。结果　自然衰减测试时间为 2 5小时 ,测定间隔为 15分钟 ;总衰减测试时间为 1 2小时 ,测定间隔为 5分钟。当空气净化器风量 <30m3 h或评价无风量空气净化产品时 ,可在 1 5m3测试舱中进行评价 ,自然衰减和总衰减的测试时间均为 6 4min ,测定间隔为 8分钟。Objective The measuring time and measuring intervals to evaluate different type of air cleaner performance to remove formaldehyde were provided. Methods The natural decay measurement and formaldehyde removal measurement were conducted in 1.5m 3 and 30m 3 test chamber. Results The natural decay rate was determined by acquiring formaldehyde concentration data at 15 minute intervals for 2.5 hours. The measured decay rate was determined by acquiring formaldehyde concentration data at 5 minute intervals for 1.2 hours. When the wind power of air cleaner is smaller than 30 m 3/h or measuring performance of no wind power air clearing product,the 1.5 m 3 test chamber can be used. Both the natural decay rate and the measured decay rate are determined by acquiring formaldehyde concentration data at 8 minute intervals for 64 minutes. Conclusion There were different measuring time and measuring intervals to evaluate different type of air cleaner performance to remove formaldehyde.
