Problems solved by technology

At the same time, the previous evaluation tests mostly used manual methods to input the corresponding load pollutants, and the input amount shifted greatly and was unstable, which directly affected the actual evaluation test results and also made the experimental results lack of comparability.

Abstract

The invention relates to a device for measuring a clean air quantity attenuation rate of an air cleaner, and belongs to the technical field of indoor air cleaner performance detection and evaluation. The device comprises a pollutant generation device, a sealed cabin, a pressure release valve, a fan, a temperature, humidity, particle, and VOCs sensor, an air pump, a programmable logic controller, an air cleaning unit composed of a nafion tube, an activated carbon filter mesh, a first air valve and a second air valve, and a humidifying module composed of a humidifier, and a third air valve and a fourth air valve connected at two ends of the humidifier. According to the device, the structure is simple, the operation is convenient, the performance parameter of removing particles and VOCs by a to-be-detected air cleaner can be simply and conveniently evaluated and the service life is evaluated.

Description

technical field [0001] The invention belongs to the technical field of performance testing and evaluation of indoor air purifiers, and in particular relates to a test device for purifying performance of indoor air purifiers, which is used for testing the attenuation rate of clean air volume of particulate matter and VOCs removed by the air purifier. Background technique [0002] Indoor air quality significantly affects people's comfort, health and work efficiency, and has attracted more and more attention. The high concentration of volatile organic compounds (VOCs) released by indoor furniture, articles and decoration materials is one of the main reasons for poor indoor air quality. Especially in recent years, with the aggravation of outdoor air particulate matter pollution, people pay more and more attention to indoor air quality. More and more consumers are purchasing indoor air purifiers to improve indoor air quality. In view of the purification performance of air purif...
