ŠURJANSKÝ, Šimon: Influence of the position of the closed air layer on damping and phase shift of the structural composition. [Bacherol´s thesis] – Technical university of Zvolen. Drevárska fakulta; Department of Physics, Electrical engineering.Thesis supervisor: Ing. Rastislav Igaz, PhD. Type of thesis: Bacherol´s thesis. Zvolen: DF TUZVO, 2020. 52 p..The aim of bachelor's thesisThe aim of the bachelor's thesis was to evaluate the influence of the position of the closed air layer on damping and phase shift of the structural composition. The first chapter analyzes the issue of using materials in wood constructions. The second chapter deals with the types of compositions in wooden constructions and the accumulation of heat. The third chapter contains of the basic properties of wood structures. The fourth chapter deals with the characteristics of building structures in non-stationary temperature conditions. It contains an explanation of the concepts of stationary and non-stationary temperature conditions as well as damping and phase shift. The fifth chapter contains of information about the types of air layers and the methodology of calculating the thermal parameters of these layers. The sixth chapter deals with the design of compositions with a closed air layer with different positions in structure. The seventh chapter discusses the calculation methodology in the software TEPLO . The final eighth chapter is an evaluation of the calculations of damping and phase shift of the structure. All calculated values of phase shift and damping are summarized here, as well as a comparison of thermal resistance and surface coefficient of the heat transfer in structures. Key words: phase shift, damping, closed air layer, TEPLO, .
