Design of an Isolated and Controlled Precision System for Determination of Thermal and Moisture Transmission Properties

Abstract

Lafayette Abstract In the analysis of thermal energy losses for a building, three components of thermal energy transfer need to be considered. These components are thermal energy conduction, convection, and radiation. The conduction component is influence by gradient of temperature in the exterior surfaces, the thermal conductivity, the effective area of exterior surface, and differences in air humidity between internal and external environment. The radiation components depend on a temperature difference, the geometry and or that of the building, and the thermal characteristics of the material used of the building. Thermal energy that is emitted to the sky from the exterior surface is considered to be a radiative component. Since radiation is a surface phenomenon, both the surface are and the surface property (emissivity) of the exterior wall material must be obtained for each exterior component of the building. After radiative heat energy losses of all components are found, they are summarized to receive the total thermal energy loss for radiation in the the effects of radiation through electromagnetic spectrum (specifically visible, infrared, and ultraviolet corresponding standard material. The ability to determine moisture content introduced through artificial means inside a contained system to maintain a test is also part of this process. This system’s parameters are determined by a variety of factors including size of test specimen and range of sources light and of this is to produce a reliable testing apparatus that corresponds to standard testing procedures for thermal transmission and moisture content properties of an and a
