Phase change materials (PCMs) are a group of functional materials that support the same purpose as a function of temperature with intrinsic capability of absorbing, storing and releasing thermal energy in form of latent heat known as enthalpy of fusion [ 1, 2, 3 ], during phase transition cycles at their operating temperatures under isothermal c. Phase change materials (PCMs) as thermal energy storage (TES) systems are potential due to their tailored thermal mass and heat comfort. These latent heat storage (LHS) materials possess extremely high energy storage density than conventional one.

Abstract Efficient and economical technology that can be used to store large amounts of heat or cold in a definite volume is the subject of research for a long time. Thermal storage plays an important role in building energy conservation, which is greatly assisted by the incorporation of latent heat storage (LHS) in building products. Phase change materials (PCMs) have shown their big potential in many thermal applications with a tendency for further expansion. One of the application areas for which PCMs provided significant thermal performance improvements is the building sector which is considered a major consumer of energy and responsible for a good share of emissions. 1. Introduction Modern infrastructures are required to satisfy increasing demands for enhanced sustainability, green economy, intelligent performance and extended longevity.

This article presents a review on phase change material application situations in building, and several aspects are discussed: phase change material major applications in building, phase change material application areas, phase change material application types, phase change material thermal-physical properties, and phase change material applica.
phase changing material
This "phase change"—from a solid to a liquid and back again—looked like the foundation for a new family of building materials, a passive process that could moderate temperature swings and lower demand on heating and cooling systems. ThermalCore was announced at a Greenbuild conference in Phoenix in 2009. This paper presents a review of the latest developments on phase change materials (PCMs) for thermal energy storage (TES) applications in buildings. The paper provides information about material requirements for TES, classification of PCM, mathematical modelling and applications of PCMs. Keywords: thermal energy storage phase change material Phase-Change Material (PCM) Transition Cycle PCM stores the heat during the melting or charging phase and releases it during the solidification or discharging phase. This process helps control the need for energy consumption in buildings. Classes of PCM in Buildings PCMs used in building applications can be classified into two large classes: Phase change materials have garnered extensive interest in heat harvesting and utilization owing to their high energy storage density and isothermal phase transition. Nevertheless, inherent leakage problems and low heat storage efficiencies hinder their widespread utilization.

A textbook definition of a phase-change material (PCM) is that it releases or absorbs a substantial amount of energy at a phase transition. The phase change of these materials is usually associated with the change of the state of matter, for example, from solid to liquid or from liquid to gas. Type of TES is known as Phase Change Materials (PCMs) that is capable to utilize the latent heat absorbed or released during the phase change of the materials. PCMs can control the ambient temperature within a specific range corresponds to the PCMs' phase transition temperature. If the phase transition temperature of the material matches the.
Classification of Phase change Materials (PCMs) Download Scientific
Phase change materials (PCMs) are a class of thermo-responsive materials that can be utilized to trigger a phase transition which gives them thermal energy storage capacity.. They have recently shown promise in architecture and construction and biological applications including smart medicine delivery systems and green solvent formulations. Thermal conductivity of phase change material is very low varies from 0.16 to 0.25 W/mK, which can be enhanced by mixing nanoparticles and metallic foam into these materials.
