    Providing the thermal reliability of window junctions during the thermal modernization of civil buildings
    (2020) Pashynskyi, M.; Dzhyrma, S.; Pashynskyi, V.; Nastoyashchiy, V.; Пашинський, М. Π’.; Π”ΠΆΠΈΡ€ΠΌΠ°, Π‘. О.; Пашинський, Π’. А.; Настоящий, Π’. А.
    In order to assess the possibility of condensation on an internal window jamb surface, the temperature fields of window junctions to brick and precast concrete walls of civil buildings were analyzed, which were massively produced in the second half of the twentieth century. This study obtained the dependences of the jamb temperature on the thickness of the additional insulation layer and the outdoor temperature. Additionally, it showed the possibility of adjusting the jamb temperature by shifting the window frame inside the building. Outside air temperatures at which no condensation will occur in the initial junction structures and after thermal modernization by additional facade insulation were determined. The results can be used to replace worn-out windows and during the thermal modernization of buildings.

Based on the results of the experiment it is specified that the temperature of the surface layer of brick walls is close to the temperature of the air. Brick sorption humidity is linearly dependent on the relative humidity of air, averaged over half of the month. Statistical analysis of long-term observations of temperature and humidity of air in Kirovograd weather station confirmed the possibility of the probabilistic description of the climatic parameters in the form of quasi-stationary random processes. Ordinates temperature distributions are described by normal distribution law and those of relative humidity and degree of saturation of the pore ceramics with moisture sorption – by the sliced normal distribution law. It is established that the process of change of temperature and humidity in the winter months can be considered practically independent. We found the average annual variation and temperature conversions through zero degrees Celsius in different geographic regions of Ukraine, which can be regarded as the number of cycles of freezing and thawing of the surface layer of the brick walls. Working formulas to determine the statistical characteristics of the degree of the ceramics pore saturation with sorption moisture through the statistical characteristics of the random process of humidity changes of air were obtained. A large inertia of moisture exchange between the wall and the ambient air causes significant smoothing of random process changes of humidity. The obtained results and working formulas are an important element of forecasting methodology of brick walls durability on the criterion of frost resistance loss of the surface layer.

One of the significant components of heat loss through the enclosure structures of buildings is the windows and junction nodes to the walls. The conducted researches allowed to determine the position of the window in the thickness of the wall, which provides the optimal thermal mode of the node, that connects the window to the wall in the given climatic conditions of operation. The results of the research may be the foundation for creating a methodology for determining the optimal position of windows of different types in the outer walls of different designs, operated in different climatic conditions. Implementation of the results will reduce the heat losses in the in the nodes of windows to the outer walls and ensure the absence of condensation in the zone of these nodes.
