The invention relates to a textile heat accumulator consisting of a textile carrier material to which a plurality of thin capillaries for water transportation are attached and which is coated with an elastomeric compound comprising finely divided phase change materials such as salt hydrates or crystalline alkyl hydrocarbons. The textile heat accumulator arranged in a roofing structure of a building facilitates the control of the heat flux into the building and the utilization of the latent heat stored within phase change material for hot water generation.

A method and corresponding structure using phase change materials to control the heat flux into and out of a building through the roof To control the heat flux through the roof, phase change materials are arranged in two locations inside the roof structure. A first phase change material is used in the upper part of the roof above the insulation. A second phase change material is used in the lower part of the roof below the insulation. The melting point of the first phase change material is higher than the crystallization point of the second phase change material.

The invention provides a device for measuring heat transfer through plate-like sample arrangements under various test conditions. The device consists of two chambers. For determining the heat transfer through the sample arrangement located between the two chambers the first chamber is set at a certain temperature or undergoes a temperature variation. Furthermore, the sample arrangement can be exposed to heat radiation provided by a surface heater in front of the sample arrangement as well as to convective heat realized by using an ventilation system. Temperature changes as a result of heat transfer through the test samples are measured within the second chamber using PT 100 temperature sensors. Furthermore, temperature measurements are taken at locations inside the sample arrangement. Infrared sensors are used to measure the irradiation intensity in front of the sample arrangement and the heat emission from the back side of the sample arrangement. Thermophysical characteristics such as thermal conductivity, thermal resistance, heat absorption, heat transition and heat emission of multilayered insulation products are determined under the various test conditions from the measured temperatures, heat fluxes as well as the thickness of the sample arrangement.
