Incorporating insulation material with phase change materials (PCMs) could help enhance the insulation capability for further building energy savings by reducing the HVAC loadings. During the phase change process between the solid and liquid states, heat is being absorbed or released by PCMs depending on the surrounding temperature. This research explores the benefits of a polyurethane (PU)-PCM composite insulation material through infiltrating paraffin wax as PCM into PU open cell foam. The new PU-PCM composite provides extra shielding from the exterior hot temperatures for buildings. Through this study, it was demonstrated that PU-PCM composite insulation could potentially help building energy savings through reducing the loads on the HVAC systems based on the building energy modeling using EnergyPlus. The Zero Energy Lab (ZØE) at the University of North Texas was modeled and studied in the EnergyPlus. It is a detached building with all wall facades exposed to the ambient. It was determined that the new PU-PCM insulation material could provide 14% total energy saving per year and reduce the electricity use due to cooling only by around 30%.

The objective of this project is to develop composite thermal insulations containing phase-change materials for use in the building envelope. The use of a phase-change insulation composite in the building envelope could result in a significant increase in energy efficiency. PhD Research provided candidate phase-change composites, and ORNL performed analytical and experimental evaluations of their thermal performance. The thermal resistance of the prototype panels was somewhat less than that of commercial products, although their thermal capacity was greater. Using these results, PhD Research has been working to modify the design and to produce practical building elements that incorporate phase-change material.

Residential buildings account for a large portion of total energy consumption in the United States. Residential energy usage can be dramatically reduced by improving the efficiency of building envelope systems. One such method is to incorporate thermally massive construction materials into the building envelope. This benefits building operation by reducing the energy requirement for maintaining thermal comfort, downsizing the AC/heating equipment, and shifting the time of the peak load on the electrical grid. Phase change materials (PCMs) are promising material for that purpose. When impregnated or encapsulated into wallboard or concrete systems, PCMs can greatly enhance their thermal energy storage capacity and effective thermal mass. In this work, a numerical study is conducted to investigate the characteristics of PCMs in building applications. For that purpose a one-dimensional, transient heat equation for a multilayered building envelope is solved using the Crank-Nicolson scheme. The effect of PCM is modeled with a latent heat source term. The code also incorporates sun loading and uses real weather data. Using this code a PCM composite wallboard incorporated into the walls and roof of a residential building was examined. The PCM performance was studied under all seasonal conditions using TMY3 data for exterior boundary conditions. Comparisons were made between different PCM wallboard locations. This work shows that there is an optimized location for PCM placement within building envelope and the location depends on the thermal resistance of the layers between the PCM and the exterior boundary. The energy savings potential was identified by comparing the performance of the PCM wallboard with the performance of a building envelope without PCM. This work shows that a PCM composite wallboard enhanced building can reduce the annual cooling load from the walls by as much as 19.7% and from the roof by as much as 8.1%. Similarly, the annual heating loads can be reduced by as much as 6% and 6.4% for the walls and roof respectively. It was also shown that the peak electricity load can be shifted by as much as three hours in the summer for a south facing wall. Studies are also conducted to compare the PCM performance across three climate zones. This work shows that PCM performance varies significantly across these zones.

Today, the application of phase change materials (PCMs) has developed in different industries, including the solar cooling and solar power plants, photovoltaic electricity systems, the space industry, waste heat recovery systems, preservation of food and pharmaceutical products, and domestic hot water. PCMs use the principle of latent heat thermal storage to absorb energy in large quantities when there is a surplus and release it when there is a deficit. This promising technology has already been successfully implemented in many construction projects. The aim of this book is to assist the scientists and to provide the reader with a comprehensive overview of the properties that characterize the phase change materials from theoretical and experimental perspectives with a focus on their technological applications. The present status and future perspectives of phase change material are discussed.
