VOC finished vehicle environment sampling cabin and testing method thereof

Abstract

The invention relates to a VOC finished vehicle environment sampling cabin, which comprises a cabin body (1), wherein the cabin body (1) is composed of a storeroom plate and a door; a buffer room (2) is arranged between the cabinet body (1) and the outside; driving guide rails are arranged in the cabinet body (1) and the buffer room (2); a VOC air treatment system (10), a sunlight simulation irradiation system (9) and an infrared irradiation device (8) are arranged in the cabinet body (1); an air conditioner (3) is arranged at the front end of the cabinet body (1); and a metering device (6) is arranged at the front end of the buffer room (2). Compared with the prior art, a test background blank in the sampling cabin can be relatively well controlled; the effects on the environment in the cabin caused by external natural factors are relieved; possibility is provided for transverse test and comparison between two vehicles or among a plurality of vehicles; air in the vehicle can be relatively accurately collected and is analyzed in a machine, so as to obtain the concentration of harmful substances such as benzene series and aldehyde ketone.

Description

[technical field] [0001] The invention relates to the technical field of automobile chemical testing, in particular to a VOC vehicle environment sampling chamber for testing the air quality in a vehicle and a testing method thereof. [Background technique] [0002] In recent years, the public has paid more and more attention to the air quality in the family car, especially the content of harmful substances such as VOC. In 2007, the relevant departments issued the national standard, that is, "HJ / T 400-2007 Sampling and Determination Methods for Volatile Organic Compounds and Aldehydes and Ketones in Vehicles". Coincidentally, Japan, South Korea, Russia and other countries have also issued related testing methods. These standards clearly stipulate that the measurement of the air quality in the car should be carried out in a dedicated VOC sampling cabin. Most of the existing vehicle cabins have the following three deficiencies: firstly, the purification ability of the blank bac...

AI Technical Summary

Problems solved by technology

Most of the existing vehicle cabins have the following three deficiencies: firstly, the purification ability of the blank background in the cabin is limited; secondly, the regulation of temperature and humidity in the cabin is greatly affected by the external natural environment; finally, the volume of the cabin is limited. Only one vehicle can be tested

[0003] Under the above circumstances, the pollution of the blank background in the VOC sampling cabin of the vehicle may interfere with the test results of the vehicle; changes in the extreme natural environment outside will reduce the controllability of the temperature and humidity in the cabin; the limited cabin volume cannot Satisfied to test the interior air quality of two vehicles at the same time for horizontal comparison
