Problems solved by technology

However, the subjective improvement effect brought by the air purifier is difficult to be intuitively and accurately recognized, and the test environment and equipment are expensive, which brings obstacles to the promotion and application of the purifier
[0004] To sum up, the existing demonstration methods and device evaluation methods are relatively single, lack of quantitative detection methods and other shortcomings, resulting in one-sided demonstration results and lack of accuracy

Embodiment 1

[0044] See figure 1 Shown: Air purifier demonstration and scoring method, including the following steps: air distribution, testing, subjective scoring, comprehensive data processing, and finally the comprehensive purification performance index P value of the purifier.

[0045] 0≤P≤1, and the smaller the P value, the worse the purification performance, and the larger the P value, the stronger the purification performance;

[0046] The calculation method of P value is:

[0047] in:

[0048] A represents the pollutant concentration, which is the pollutant concentration measured by the pollutant sensor or tester.

[0049] a represents the subjective perception score of pollutants, which is the subjective scoring of pollutants by users through seeing and smelling. The subjective feeling classification is set to n levels, and n ≥ 3 levels, the score of pollutant level 1 is 1 point, and the score of pollutant level n is n points. The higher the concentration of pollutants, the h...

Embodiment 2

[0055] The air cleaner demonstration and scoring method described in Embodiment 1 can be realized by an air cleaner demonstration and scoring device.

[0056] The air cleaner demonstration and scoring method described in Embodiment 1 can be realized by an air cleaner demonstration and scoring device.

[0057] See figure 2 As shown, the air cleaner demonstration and scoring device includes an air distribution system 10 , a testing system 20 , a scoring system 30 and a data processing system 40 .

[0058] Specifically:

[0059]The gas distribution system 10 includes a pollutant generator 11 and a gas distributor 12 connected to the pollutant generator 11 . The pollutant generator 11 is a sealed box in which different sources of pollution are placed, and the box is connected to a power source through a gas pipeline, and the power source can be a pressurizer, so that it can promote its internal The gas is exhausted outwards. The aforementioned pollution sources can be lit cig...

Embodiment 3

[0070] In combination with the method described in Example 1 and the device in Example 2, the following measurements are specifically made.

[0071] Take 3 demo boxes and set them as No. 1 demo box, No. 2 demo box 2 and No. 3 demo box. No. 1 demonstration box is used as a blank control, no air purifier is placed inside, No. 2 demonstration box is put into purifier A, and No. 3 demonstration box is put into purifier B. The pollutant sensor adopts TVOC sensor and PM2.5 sensor.

[0072] Put a certain amount of paint solution in the pollutant generator, and send the pollutants generated in the pollutant generator into three demonstration boxes through the gas distributor through a small blower. After stabilizing for 1 minute, read the sensor data, and the C1 is 0.91 mg / m 3 , C2 is 0.93mg / m 3 , C3 is 0.91mg / m 3 . Start demo

[0073] Ask 5 volunteers to smell the peculiar smell in the demonstration box through the smell mouth, and register the pollutant smell into 4 levels. Th...

Abstract

The invention discloses an air purifier demonstration and scoring method and device. The method comprises the following steps of gas distribution, testing, subjective scoring and data comprehensive processing, and finally a comprehensive purifying performance index P value of an air purifier is obtained, wherein P is no less than zero and no more than 1, the smaller the P value is, the poorer the purifying performance is, and the larger the P value is, the higher the purifying performance is. The calculation method of the P value is shown in the specification. The air purifier demonstration and scoring method has the advantages that the demonstration result is relatively comprehensive, and the scoring accuracy is relatively high. The invention further discloses an air purifier demonstration and scoring device.

Description

technical field [0001] The invention relates to the technical field of equipment detection, in particular to an air purifier demonstration and scoring method. The invention also relates to an air cleaner demonstration and scoring device. Background technique [0002] People spend more than 80% of their lives indoors (including cars). As interior decoration, car interiors, and atmospheric smog continue to affect people's indoor air quality, air purifiers have gradually entered people's lives. Indoor environment to improve indoor air quality. Among them, indoor air quality reflects the concentration of indoor pollutants, which directly affects people's sensory experience and is directly related to people's health. For the comprehensive pollutant concentration and human sensory experience, the ASHRAE organization proposes the definition of good indoor air quality: "There are no known pollutants in the air that reach the harmful concentration indicators determined by recognize...
