Description
Technical field
The present invention relates to testing techniques of equipment field, especially relate to a kind of air purifier demonstration and methods of marking.This
Invention further relates to a kind of air purifier demonstration and scoring apparatus.
Background technology
The time having more than 80% all one's life of people is spent, along with in interior decoration, automobile in indoor (containing in car) environment
Decorations, atmospheric haze etc. constantly affect the indoor air quality of people, and air purifier starts to progress into the room internal ring of people
Border, to improve indoor air quality.Wherein, indoor air quality has reacted the concentration of indoor pollutant, and it directly influences people
Sensory experience, and be directly connected to the healthy of people.Comprehensive pollution substrate concentration and human body are experienced, ASHRAE
Tissue proposes the definition of good indoor air quality: " do not have known pollutant to reach generally acknowledged institute of authoritative institution in air
The adverse concentration index determined, and the vast majority of people's (>=80%) being in this air do not has meaning with thumb down to this ".
It is pollutant levels and the combination of human body impression that this definition embodies indoor air quality.Dirt in aforementioned air quality
Dye substrate concentration relies primarily on specialty detection measuring apparatus, and the sensory experience of air quality is mainly heard by range estimation, nose and determines.
General, people, by the casing of fixed volume, demonstrate sky by the method for range estimation air quality change
The clean-up effect of gas purifier.Such as, Authorization Notice No. is the Chinese utility model patent of CN 2458684Y: air purifier
Demonstration box, discloses the inverted transparent demonstration box of a kind of opening, and employing smoking device is as polluter, by the method for range estimation
The displaying depurator removal effect to particulate matter directly perceived.But, the method is only to the pollutant demonstration effect that can be arrived by visual observation
Really, for the air pollutants (such as formaldehyde, toluene, ammonia etc.) that indoor are main, because mostly cannot the most directly being observed and nothing
Method obtains demonstrating effect.And pollution concentration is unknown, depurator performance cannot be shown by the method for detection removal efficiency,
It is difficult to obtain the most accurately expressing.The most such as, Application No.: 200910084439.6 Chinese invention patent applications: Yi Zhonghuan
Border test chamber can open the indoor air pollutants concentration change before and after depurator by the test equipment of specialty by detection,
Evaluate the performance of air cleaning.But, the subjectivity that air purifier is brought is improved effect and is difficult to intuitively and accurately be recognized by people
Know, and test environment is expensive with equipment price, brings obstacle to the promotion and application of depurator.
In sum, existing demenstration method and device evaluation method are the most single, lack the shortcomings such as detection by quantitative means, lead
Cause demonstration result is unilateral and lacks accuracy.
Summary of the invention
It is an object of the invention to provide a kind of air purifier demonstration and methods of marking, it is the most complete that it has demonstration result
Face, the feature that scoring accuracy is higher.The invention also discloses a kind of air purifier demonstration and scoring apparatus.
