Aerosol test chamber

A device for investigating aerosols includes a test chamber having a panel defining an enclosed interior volume. The panel has (i) a first wall having a surface defining an interior of the test chamber, (ii) a second wall defining an exterior of the test chamber, (iii) a void space between the first wall and the second wall, (iv) a panel inlet in communication with the void space, and (v) a panel outlet in communication with the void space. The apparatus includes a chamber inlet port and a chamber outlet port each extending through one of the panels and in communication with the enclosed interior volume. The apparatus includes a fan disposed in the enclosed interior volume and positioned and configured to mix air in the enclosed interior volume. The device includes a trapping port extending through one of the panels and includes a valve to allow sampling of the contents in the enclosed interior volume. 一种用于研究气溶胶的设备包括具有限定封闭内部容积的面板的测试室。面板具有(i)具有限定测试室的内部的表面的第一壁，(ii)限定测试室的外部的第二壁，(iii)第一壁与第二壁之间的空隙空间，(iv)与空隙空间连通的面板
