This thesis is aimed at studying the possibility of using air injected into the inter-window space as an internal source of heat in the construction of single-chamber rack-crossbar facade glazing to increase the energy efficiency of facade glazing systems. In the process of the study examined the experience of previous years in the field of increasing heat resistance of translucent structures, was made theoretical and experimental mathematical model describing the process of change of the temperature field inside the construction of a heat-resistant construction of a single-chamber rack-crossbar facade glazing. After preparing and structuring the data obtained as a result of calculating the mathematical model, an experimental sample of a heat-resistant construction of a single-chamber rack-crossbar facade glazing was created. Next, six tests were conducted on three different types of construction at ambient temperatures of -20 and 50 degrees Celsius. The data of a group of six sensors obtained during the experiment were structured, analyzed, and based on the results of the experiments, graphs and color schemes of temperature changes on the internal and external surfaces of the structure were made, linear graphs of temperature changes along the thickness of the experimental structure were made. |
