Climate chamber for measuring VOC release amount through multi-chamber method

Abstract

The invention discloses a climate chamber for measuring the VOC release amount through a multi-chamber method. The climate chamber comprises a case and a clean gas generation device, the case is provided with a front case body and a rear case body, six experiment cabins and a jacket temperature control system are arranged in the front case body, a pressure regulating valve is arranged on the frontsurface of the front case body, a sampling pipe is arranged on a cabin door of each experiment cabin, and a dry and wet gas mixing humidity regulating system and a numerical control acquisition system are arranged in the rear case body on the rear side of each experiment cabin; an electric control mechanical chamber is arranged on one side of the case, and a logic control system, a refrigeratingsystem and a man-machine interaction system are arranged in the electric control mechanical chamber; the clean gas generating device is connected with the dry-wet gas mixing humidity adjusting systemand the electromagnetic valve flow adjusting control system, the dry-wet gas mixing humidity adjusting system is connected with the experiment cabin, and the experiment cabin is connected with the numerical control collecting system. Compared with the prior art, the climate chamber has the advantages that the background concentration requirement specified in the national standard is completely met; the energy consumption is low; the desorption time is reduced; and the use efficiency of equipment is improved.

Description

technical field [0001] The invention relates to VOC emission measurement equipment, in particular to a multi-cabin method VOC emission measurement climate chamber. Background technique [0002] In recent years, the state has issued a series of standards for the concentration limits of formaldehyde and TVOC. However, the background concentration of toxic and harmful gas emission detection cabins on the market cannot meet the requirements of major scientific research institutions, corporate schools, and testing institutions, and cannot be analyzed. Emission of volatile organic compounds in materials. Therefore, developing a multi-chamber method for VOC emission measurement climate chamber has become an urgent problem to be solved by those skilled in the art. Contents of the invention [0003] The present invention is to solve above-mentioned deficiency, provides a kind of multi-chamber method VOC emission measuring climate chamber. [0004] Above-mentioned purpose of the p...
