Study of heat shielding qualities of a brick wall corner with additional insulation on the brick

摘要

This work presents the theoretical investigations results for the brick wall thermal protection properties exterior corner with the insulated layer SUPERROCK mineral wool. As the outer corner of the enclosing structures has lower thermal protection properties than the other part of the wall, it needs additional insulation. Two variants of additional insulation were considered in the work, in the deepened outer surface and in the middle of the brick wall. In this case, the additional heater was not continuous, but divided into two parts and shifted from the corner. The length and volume of additional insulation for different variants were determined. The optimal variant of the proposed schemes was determined by the minimum volume of the heater and compared with the existing ones. The volume of additional insulation is set at 1 meter of the fence height. For the proposed variant of the location for the heater in the brick wall middle, its thickness in the brick cavity, the length and offset from the corner magnitude were determined. For a location-variant of the heater in the deepened on the outer surface of the fence bricklayer, the length of the additional insulation and its displacement from the corner were determined. The thickness of additional insulation was taken 130 mm (width of the brick and seam between the bricks). Studies were carried out for the first temperature zone.
