The goal of this work was to produce a new high performance PCM, using a combination of RT 100 (paraffinic hydrocarbons) with expanded graphite (EG). The resulting composite performed extremely well in quality testing. Thermal conductivity was measured using the TPS method, and was found to be much higher in the composite than it was in the basic RT 100 materials. Thermal conductivity did not decrease during melting cycles. The ability of ...
Phase change materials (PCMs) are an attractive solution for reducing energy usage because of their efficient latent heat storage abilities. This paper examined chemical and physical properties of micro-PCMs before and after their integration with concrete samples. A Thermal Constants Analyser (TPS) measured the thermal conductivity of the PCM-concrete using the transient plane source (TPS) method. Results showed that overall, the thermal conductivity of the concrete was unchanged after the ...
Microencapsulated phase change materials (MPCMs) are excellent materials for the storage of thermal energy, and through their dispersal into a carrier fluid, microencapsulated phase change slurries (MPCS) can be prepared. These slurries exhibit both excellent thermal energy storage and heat transfer properties. A series of MPCS were prepared for this research and subsequently tested for thermal conductivity and specific heat. Other methods of quantification include DSC, TGA, rheometry, and infrared ...
