US 2006/0188672 A1 · Thermal filtering insulation system

Abstract

A resistance/capacitance (RC) model thermal filtering system is disclosed. The resistance is provided by traditional insulation and the capacitance is provided by a phase change material (PCM). The RC model comprises the placement of a layer of PCM proximate an outer surface of a wall of an interior of a structure and the placement of a layer of traditional insulation adjacent the PCM. Accordingly, the PCM is placed between the wall and insulation. In this arrangement, heat energy absorbed by the PCM during peak hours of the day is routinely released to the interior (path of least resistance) of the structure during non-peak cooler times of the day. Packaging containing a matrix of pockets for containing a PCM compound facilitates a simple method of containing and placing the PCM layer. In one version, a containment medium is preferably perlite bound within a matrix with a sealing material, although other media can be employed for containing the phase change materials, such as vermiculite.

Dependent claims

A thermal insulation system comprising:

a phase change material contained within packaging, said phase change material placed proximate to an outer surface of a wall of an interior of a structure wherein substantially no insulation is placed between the phase change material and the outer surface of the wall of the interior of the structure;
and
an insulation layer placed adjacent to said phase change material such that said phase change material is between the wall of the interior of the structure and the insulation layer.
