Heat transfer analysis of roof drains in the calorimetric chamber

Abstract

The paper describes the non-stationary behavior of a roof drain during experimental measurement in the climate simulator. Many buildings use a fully or partially flat roof where it is necessary to use the roof drainage. Thermal behavior of roof drainage is very important from the point of view of heat transfer analysis and potential condensation inside buildings. The measurement was performed for two types of roof drains. The first drainage is a simple single-shell and the second is double-shell drainage. The results show the effect on the thermal transmittance of the roof section and also the minimal effect of condensation on the non-insulation part of the drainage. © 2017, World Scientific and Engineering Academy and Society.
