Numerická a experimentální analýza přenosových jevů ve vícekomorových izolačních sklech nového typu

Abstract

This study focuses on the transport phenomena within glazed structures, where the internal space is equipped with one or more films. These films exhibit positive characteristics in terms of heat transfer within the glazing and are advantageous due to their low weight.

The theoretical part of the study concentrates on heat transfer within glazing in general, with a primary emphasis on radiative heat transfer. Radiative heat transfer is identified as a key mechanism with significant potential for improving the thermal insulation properties of glazing.

The practical part provides information regarding the conducted experimental and numerical analysis to determine the heat transfer coefficient in glazing with inter-pane polymer film. It addresses practical issues associated with the use of inter-pane films, considering exposure to external influences. It establishes the thermal load caused by solar radiation in coated inter-pane films, which are commonly used in practice. Subsequently, within the research, a new thin layer was designed to reduce the thermal load on glass and polymer films.

The final part of this work focuses on the issue of radiation of insulating glass into the clear night sky. This issue, in the context of glazing in construction, is under-researched and offers a wide spectrum of possibilities for development and research in this area.
