Title of the articleCalculation of the reduced heat transfer resistance of translucent structures made of aluminum profiles
Abstract.Problem statement. The purpose of the research is to determine the specific heat loss of multi-chamber aluminum profiles of translucent structures by considering the influence of the material of the glass unit spacer. The primary method of research is the calculation of two-dimensional stationary temperature fields. Results. Based on the results of the numerical simulation we calculated the thermal technical characteristics of the aluminum profile of various versions and determined the influence of the material for the manufacture of the spacer frame on the heat loss through the elements. Based on the obtained data we performed the calculation of the reduced heat transfer resistance of a translucent enclosing construction with a different layout of frame profiles. Conclusions. The significance of research results for construction lies in the possibility of using the specific heat losses of multi-chamber aluminum profiles for calculating the thermal characteristics of translucent structures with a random layout of profiles, which is especially important at the design stage. It is shown that a significant proportion (30-48 %) of heat losses through translucent structures is additional heat loss through an aluminum profile. Depending on the selected configuration of the translucent structure, the reduced heat transfer resistance can vary within 15 %.
Keywords.reduced heat transfer resistance, translucent structure, specific heat loss, profile, spacer.
