Numerical study of heat gradient and crossing energy to around building walls containing phase change materials in Kashan temperature conditions
The application of phase change materials (PCM) in the variant parts of building because of the high capacity these materials, lead to an improvement in temperature conditions and reduction in energy consumption. Due to the high dependency of the performance of these materials to the ambient temperature fluctuations, their applications in climates with extreme temperature fluctuations has a sig...
متن کاملNumerical Investigations of Heat Transfer in Phase Change Materials (pcms) Using Non-thermal Equilibrium Model
Phase change materials (PCMs) are drawing increasing attention of researchers nowadays, and they play a pivotal role in thermal energy storage (TES) used in renewable energy resources applications, since these renewable energy, such as solar energy, wind energy and tidal energy, are intermittent and not available at any time. However, most of PCMs suffer from low thermal conductivities prolongi...
متن کاملExperimental Investigation of Sinusoidal Tube in Triplex-Tube Heat Exchanger during Charging and Discharging Processes Using Phase Change Materials
In this experiment effect of two full and half width sinusoidal inner tubes in triplex-tube heat exchanger with phase change material (PCM) was investigated. Length and diameter of the tubes have been chosen such that the area of each tube to be the same. Charging and discharging processes were carried out by inner tube, outer tube and both. Results indicated, PCM melting and solidification tim...
متن کاملPreparation and Characterization of Microencapsulated Phase Change Materials for Use in Building Applications
A method for preparing and characterizing microencapsulated phase change materials (MPCM) was developed. A comparison with a commercial MPCM is also presented. Both MPCM contained paraffin wax as PCM with acrylic shell. The melting temperature of the PCM was around 21 °C, suitable for building applications. The M-2 (our laboratory made sample) and Micronal® DS 5008 X (BASF) samples were charact...
متن کاملAnnual energy analysis of concrete containing phase change materials for building envelopes
This paper examines the annual energy and cost savings potential of adding microencapsulated phase change material to the exterior concrete walls of an average-sized single family home in California climate zones 3 (San Francisco, CA) and 9 (Los Angeles, CA). The annual energy and cost savings were larger for Southand West-facing walls than for other walls. They were also the largest when the p...
