Modelling and simulation of a test cell for hygrothermal durability testing of thermal insulation composite systems (ETICS)

Swisspor is one of the leading manufacturers of insulation and seals for the building envelope. As a company, Swisspor has a special interest in planning a test cell according to the current normative specifications (FprEN16383) in order to be able to test and develop its products. During the test, three different load phases will act on the thermal insulation composite systems (ETICS). The test object is exposed to heat, frost and water. These load phases represent a large challenge when planning the test facility. In the context of this work a tool was developed which shows the hygrothermal behaviour of the test facility. The tool is based on the object-oriented «Modelica-Approach». In this thesis it turned out that the coupled unsteady heat and moisture transport can be described with the «Modelica-Approach» with good correlation to other programs. Based on this, the hygrothermal behaviour and the determination of the heating and cooling power requirements for the test cell could be determined.
