Abstract
- The hygroscopic structures can improve the comfort of indoor air by buffering the changes of relative humidity. Part of the indoor air moisture load can be absorbed in hygroscopic structures or other hygroscopic mass, which reduces the relative humidity peaks during short period (daily) loads. The main interest is in the moisture transfer between the indoor air and the hygroscopic structures (or mass) and what is the effective moisture capacity of the structure in the typical range of the diurnal humidity variation. In order to study this effect, a test method and device have been developed. This paper presents the test method and device and studies the determination of the moisture capacity using structures and material layers that are typically used or possible to be in contact with the indoor air.
