National pu­ri­fier test­ing agency re­leases new stan­dard

Global Times – Metro Beijing - - ENTERPRISE -

China House­hold Ap­pli­ance Stan­dard and Tech­nol­ogy In­dus­try Al­liance, an af­fil­i­a­tion of China’s lead­ing home ap­pli­ance agency – China House­hold Elec­tronic Ap­pli­ance Re­search In­sti­tute (CHEARI) – re­leased the first global as­so­ci­a­tion stan­dard for in­tel­li­gent air pu­ri­fy­ing fans in Bei­jing on Jan­uary 23. By sens­ing pol­lu­tion, cap­tur­ing it and then cir­cu­lat­ing cleaner air, these ma­chines are en­gi­neered to prop­erly pu­rify the air in a room.

Work­ing in con­junc­tion with the Bri­tish tech­nol­ogy com­pany Dyson’s en­gi­neers, ex­perts at CHEARI have con­structed a 27-square-me­ter test chamber de­signed to bet­ter re­flect the av­er­age home size of Chi­nese con­sumers. Re­search sug­gests that the av­er­age size of a Chi­nese liv­ing room is 27 square me­ters.

The new method will sit along­side China’s ex­ist­ing national stan­dard, which uses a smaller test­ing chamber at 12 square me­ters to test ma­chines un­der max mode only. The ex­ist­ing stan­dards have no mea­sure­ment of in­tel­li­gence or whether a ma­chine de­liv­ers uni­form clean­ing in a larger fam­ily room. The new test­ing method as­sesses a ma­chine’s abil­ity to re­move harm­ful par­ti­cles and gases, the uni­for­mity of the clean­ing per­for­mance de­liv­ered around the whole room and air­flow pro­jec­tion. All ma­chines are tested us­ing their au­to­matic pol­lu­tion de­tec­tion func­tion.

By en­larg­ing the size of the test chamber com­pared to the ex­ist­ing pu­ri­fier stan­dard and in­creas­ing the num­ber of test sen­sors to nine, the chamber is able to de­tect the ac­cu­racy of a ma­chine’s au­to­matic func­tions and en­sure that the ma­chine cleans all the air in the room prop­erly. In the con­text of a home, it would en­sure that a per­son on one side of the room re­ceives a sim­i­lar air qual­ity to a per­son on the other side of the room. There is also no need to man­u­ally change the ma­chine based on guess­work or costly air qual­ity mon­i­tors.

“We are al­ways look­ing at ways to ac­cu­rately guide con­sumers to­ward tech­nolo­gies by in­te­grat­ing high per­for­mance, smart­ness and uni­for­mity of pu­rifi­ca­tion, and we rec­og­nize the grow­ing need for in­tel­li­gent air pu­ri­fy­ing fans,” Lu Jian­guo, the Chief Test En­gi­neer at CHEARI said. “Dyson leads the way in this cat­e­gory of pu­rifi­ca­tion so we’ve worked closely with their en­gi­neers to bring a test method to China that pushes the pu­rifi­ca­tion agenda for­ward and wel­come other man­u­fac­tur­ers to en­ter into this new cat­e­gory.”
