Overpressure Chamber for Testing in High Air Purity Conditions

Abstract

Volatile organic compounds (VOC) released into the air contribute to adverse climate changes, discomfort, and harmful effects on the human body. Principal sources of VOC emissions are industrial processes and, in the case of rooms for human residence, building materials and indoor furnishings. VOC emissions are monitored and restricted in line with legislation prevailing in the European Union and most countries of the world. The chamber method is used to measure noxious substance emissions from building materials and indoor furnishings.The paper analyses the impact of regulatory requirements concerning emission test parameters and apparatus on technical solutions as part of air preparation assemblies and emission measurement chambers. The design of a 0.225m 3 steel chamber is presented, which was developed by our Institute based on our experience in the design and construction of similar apparatus. Results of verification testing are described.

“…The Łukasiewicz-Institute for Sustainable Technologies in Radom, Poland, carries out research to address this problem in the process of prototype device design, development and manufacture. Some of the solutions developed in response to the needs expressed by business owners and scientific institutions include the following: a painting robot (dosing of paints) [1]; chambers for gasometric testing (dosing of components of the gaseous atmosphere) [2,3]; a chamber for concrete carbonation testing (dosing of CO2); VOC chambers (dosing of air streams of different humidity) [4,5]; a device for erosion testing (dosing of an abrasive agent) [6]; and a production line for the production of cable moisture barriers (dosing of a powder superabsorbent) [7].…”
