Problems solved by technology

First of all, the size of the cabin is not built according to the building model, and the gap between the simulated real space is enlarged, and the size is large, which is mainly used for the study of pollutants in furniture; second, the air inlet is not purified, which may cause background in the cabin If the concentration is too large or fluctuates seriously, the reliability of the test data will decrease, and if the gas at the outlet is not purified, it will pollute the indoor air, and then pollute the air in the cabin again

Embodiment Construction

[0013] (1) Test cabin body 10

[0014] According to the building modulus, the real room can be simulated as much as possible. The internal volume of the cabin body (10) is 1m×1m×0.6m; the material of the cabin body is made of double-layer mirror stainless steel material lined with foam material to ensure that there is no adsorption inside and no gas pollutants itself Release and have a certain thermal insulation performance. The cabin body is designed with an air inlet (7), an air outlet (12) and a gas sample collection port (11). The cabin body is designed with a hatch, which is easy to open and convenient for placing samples into the cabin. The door is opened with a rubber gasket to ensure its sealing effect. In order to ensure that the gas can be mixed evenly in the cabin and have a similar effect to the airflow in the actual room, a combination of multiple air inlets and outlets and low-speed fan (8) technology is used in the cabin, and the corners of the cabin are treate...

Abstract

The invention relates to a small-sized environmental test chamber for pollutant release researches, which comprises a chamber body, an air generation system, a temperature-humidity control system, a sampling system and an air purifying device. By utilizing the small-sized environmental test chamber for simulating to approach real space, the temperature, the humidity and the air interchange ratio inside the chamber body can be controlled according to experimental conditions with low cost and simple operation. Meanwhile, the chamber body is provided with the purifying device, which can purify air samples at an air inlet and an air outlet so as to improve experimental conditions, be beneficial to acquiring real and reliable test data and avoid polluting indoor air.

Description

technical field [0001] The invention relates to a small-scale environmental test chamber for research on the release of pollutants, in particular to a small-scale environmental test chamber for research on the release of volatile substances in decoration materials, and belongs to the technical field of test devices. Background technique [0002] At present, indoor air quality is generally poor, which poses a great threat to people's health. As far as our country is concerned, the main cause of indoor air pollution is poor decoration, that is, some interior decoration materials that contain a large amount of harmful substances such as formaldehyde and volatile organic compounds are used in the decoration process. Considering the diversity, trace and accumulation of indoor pollutants, the research on indoor pollution sources takes the simulation research of environmental test chambers as the main means. [0003] China (Application No.) Patent No. 200520047927 "A climate tempe...
