This paper describes a global analysis to determine the increase in annual energy output attained by a PV system with an integrated phase change material (PCM) layer. The PCM acts as a heat sink and limits the peak temperature of the PV cell thereby increasing efficiency. The simulation uses a...

There is increasing interest in using phase change materials (PCMs) to store energy within refrigeration equipment. The main purpose is to increase the thermal capacity of the equipment and maintain product temperature within safe limits during frequent door openings, on–off cycling of the...

This paper presents a mathematical model of a thermal energy storage (TES) system filled with phase change material (PCM) encapsulated in spheres. Using the ε-NTU method, a suitable two dimensional representation was developed capable of predicting the heat transfer during phase change....

The thermal management systems using EG-based phase change materials (PCMs) can provide power batteries with a proper operating temperature, slow temperature rise rate and uniform temperature distribution. In this study, a systematical investigation on the effects of thermo-physical properties...

A new method for supercooling suppression of microencapsulated phase change materials (PCMs) has been developed by optimizing the composition and structure of the microcapsule resin shell. The microcapsules comprising paraffin octadecane encapsulated in melamine–formaldehyde resin shell were...

Nanocapsules containing phase change material (PCM) n-dodecanol as core and polymethyl methacrylate (PMMA) as shell were synthesized by miniemulsion polymerization with polymerizable emulsifier DNS-86 and co-emulsifier hexadecane (HD). The nanocapsules were characterized by using Fourier...

The use of latent heat thermal energy storage for thermally buffering vehicle systems is reviewed. Vehicle systems with transient thermal profiles are classified according to operating temperatures in the range of 0–800°C. Thermal conditions of those applications are examined relative to...

A LiNO3/KCl-expanded graphite (EG) composite phase change material (PCM) was prepared for solar thermal energy storage application at high temperature (∼200°C). In such composite material, eutectic system LiNO3/KCl is characterized by high phase change latent heat and EG serves as the heat...

Thermal storage systems with phase change materials are predominantly designed, analysed and optimised through numerical modelling. An alternative simplified method is being proposed for the characterisation of these phase change thermal storage systems. The method is based on the...

The influence of radiation heat transfer during the phase change process of a storage material has been numerically analyzed in this study. Emphasis has been placed on the thermal characterization of a single constituent storage module rather than an entire storage system, in order to precisely...
