briefly reviews energy developments and storage techniques, with special emphasis on thermal energy storage and the use of PCM …. It thereafter illustrates first results obtained when encapsulating NaNO3/KNO3-PCM in an AISI 321 tube, as example of a … storage application using a multi-tubular exchanger filled with PCM. To increase the effective thermal conductivity of the PCM …

A prototype thermoelectric system integrated with PCM (phase change material) heat storage unit for space cooling has … been introduced in this work. The PCM heat storage functions as cooling source and carries, partially at least, the cooling … test for efficacy of PCM heat storage unit shows that 35.3% electrical energy has been saved from using PCM heat storage …

In this study, a paraffin/diatomite/MWCNTs (multi-wall carbon nanotubes) composite PCM (phase change material) was … selecting an optimum diatomite as the supporting matrix for the new composite PCM, the pozzolanic reactivity and paraffin …. It, therefore, was used as the supporting matrix of the new paraffin/diatomite/MWCNTs composite PCM. The thermal …

PCM (phase change material) is one of the most popular media in TES (thermal energy storage) system for its high energy … that the highest effective thermal conductivity of composite PCM was 50.78 W/(mK), which was 110 times higher than that of … salt powder. The additive of ENG-TSA in the PCM caused a slight decrease in latent heat, but there was no remarkable …

Phase change materials (PCM) with a transition temperature around 45°C can be used in various applications, e.g. as … of about 300J/g was reported in literature. To investigate the applicability of pinacone hexahydrate as a PCM, we …

selection of a PCM can increase or eliminate the environmental benefits obtained. …

Thermal energy storage (TES) using phase change materials (PCM) can be used for load shaving or peak load shifting when … coupled to a heating, ventilation, and air-conditioning (HVAC) system such as heat pump. In these systems the PCM is embedded … in packages or used in bulk, so the compatibility of the encapsulation materials and the PCM is a key factor to ensure …

The thermal performance of a PCM based solar chimney is experimentally investigated in this paper. The research is … that for a same charge period of 7h 10min though the PCM does not fully melts in the cases of 600W/m2 and 500W/m2, the …

This article describes the development of a CFD 2D model of a new type of ventilated active façade which includes a PCM … tested to model the PCM. To model the radiation, S2S and DO sub-models were tested. RNG k–ε, Standard k–ω and SST k … consideration it was suitable to consider the PCM to be a solid material with variable Cp. The DO model accurately reproduced the …
