Passys experimental facilityThe Passys cell is an insulated room 5 x 2.5 x 2.5 m. Its original purpose was as a calorimeter to evaluate the thermal performance of walls, which were inserted in the south facing wall of the structure. Recently, the cell has been used as an insulated, air tight container to measure moisture exchange between air and porous building materials. The original design is described in the Passys description pdf file. The cell is illustrated in pictures in two zip files: Passys_20091114.zip 15 Mb Passys_20091119.zip 45 Mb |
