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

2018

View full text Add to dashboard Cite

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.

Abstract.The results of theoretical studies of heat-shielding properties of the angle of external wall a residential building are presented. The brick wall thickness of 510 mm was considered. The studies were performed for the I-st temperature zone of Ukraine. Heat insulation was located on the external side of enclosure. Thermal protection problems of the angle are consideration of the impact of heat-conductive inclusion on adjusted heat transfer resistance of enclosure. Conductive inclusion on the external angle area is its configuration. An additional layer of insulation in the angle area is necessary to use for bringing the level of thermal protection of angle area to the standards. The results of calculations of two-dimensional temperature fields were used for the analysis of thermal protection. Two options for additional insulation were studied. The first option: continuous strip insulation covering the external wall angle. Another one provides division of additional insulation layer into two parts and displacement them from the angle within the design scheme. Studies were performed for different thickness of additional insulation. There was additionally taking into account the value of insulation displacement from the angle for the second option. The optimal location and size of additional insulation were determined. The minimum amount of additional insulation under which the thermal protection requirements are performed was accepted like optimality criterion.

“…An experimental method of calculating the coefficient of thermal homogeneity was shown by Vasilyev et.al. [8] and based on that method a metric of temperature was obtained using thermovision controller and applied to conduct thermal testing of climate chamber [8]. It turns out the described method reduced the time and cost of testing compared to methods described in Russian standards [8].…”

Thermovision analysis of heat and power plant chimneys technical condition

et al. 2022

This paper describes the thermovision analysis conducted on two types of chimneys: structural steel one and reinforced concrete one located in Kielce Heat and Power Plant, Poland. As a result of the research temperature distribution obtained from the thermograms were shown on the diagrams and analysed along their horizontal direction. It proves, both of the chimneys that were examined are in proper technical condition. The article also discusses the importance of the analysis as a diagnostic tool that allows early-stage detection of structural technical conditions and thermal insulation degradation. A factory’s chimney should work constantly to maintain its operation, since modifications in the production line caused by construction works are high cost and usually difficult to implement. However, analyses are critical to ensure chimneys are well maintained. The literature presents many examples of destructive influence of high temperature on the reinforced concrete chimneys. When failure of chimneys occurs, even the whole plant unit may be closed down. Thermography is then an ideal, non-destructive and cost-effective instrument for structure testing and can therefore be a useful, initial step to locate potential damage.
