家用新风净化机标准体系解析

Standard System Analysis of Outdoor Air Clean Ventilator

家用新风净化机兼具新风和内循环净化等功能,甚至热回收和加热等附加功能,集合了新风机和空气净化器的产品特点。目前还没有统一的产品标准,通过不同结构新风净化机和不同标准分析,选择GB/T 34012、GB/T 18801和GB/T 21087等标准适合新风净化机的检测项目,包括净化效率、机外静压、净化能效、噪声、容尘量、洁净空气量、累积净化量、交换效率(温度、焓和湿量)、有效换气率和凝露试验(制冷工况、制热工况I和制热工况II)等。由于新风机和空气净化器的净化性能的检测方法和指标均有差异,未来应制定适合新风净化机产品自身特点的产品标准,统一净化性能的检测方法。

Outdoor air clean ventilator has the functions of outdoor air purification and internal circulation purification,and even additional functions of heat recovery and heating,which integrates the functions of outdoor air ventilator and air purifier.At present,there is no uniform product standard.Based on the analysis of different structures and standards of Outdoor air clean ventilator,standards such as GB/T 34012,GB/T 18801 and GB/T 21087 are selected to be suitable for the testing items of Outdoor air clean ventilator,including cleaning efficiency,available pressure,EER,noise,dust holding capacity,clean air delivery rate(CADR),cumulate clean mass(CCM),purification efficiency,exchange effectiveness(temperature,enthalpy and humidity),net air exchange rate and condensation test(refrigeration condition,heating condition I and heating condition II),etc.Due to the differences in the test methods and index of the purification performance between outdoor air ventilator and the air purifiers,the product standards suitable for the characteristics of the outdoor air clean ventilator should be formulated in the future,and the test methods of the purification performance should be unified.
