Effect of Different Initial Moisture Contents on the Characteristics of Coupled Heat and Moisture Transfer of a Reinforced Concrete-EPS Thermal Insulation Composite Wall in Harbin

Abstract:

This paper investigated the effect of different initial moisture contents on the characteristics of coupled heat and moisture transfer of a reinforced concrete-EPS thermal insulation composite wall in Harbin. The change of the moisture content with time and the change of the heat transfer coefficient with time of the reinforced concrete-EPS thermal insulation composite wall at different initial moisture contents in Harbin were numerically simulated. The relative humidity and the quantity of condensed water in the air layer of the reinforced concrete-EPS thermal insulation composite wall were also calculated. The paper provides a scientific proof for the influence of the process of construction of a reinforced concrete-EPS thermal insulation composite wall on the energy-saving of buildings.
