“…The performance of the hot water tanks, modernised by adding containers with PCMs, was also investigated by, among others [28][29][30][31]. Finally, a list of 23 sources on modelling and experimental investigation of PCM-hot water tanks reported in literature was given by Nkwetta et al [32].…”

Abstract. This paper presents briefly the state of the art literature review with respect to research in the field of latent heat storage systems as elements of heat only, power only or combined heat and power (CHP) plants utilizing renewable energy sources (RES) for residential applications. Next, a paper introduces initial research carried out in IMP PAN in Gdańsk, Poland, aimed at development of a prototype latent heat storage unit. Identification of the suggested application for the storage unit in a given system is presented. The first stage of development of a prototype heat storage unit, namely a process of PCM pre-selection is discussed.

“…These systems also undergo buoyancy dependent stratification which tends to affect heat transfer processes. Various researchers have therefore explored the possibility of using phase change materials (PCMs) as storage media since they have much larger heat storage capacities than sensible heat materials [1][2][3][4]. However, repeated thermal cycling of pure PCMs does result in some drawbacks.…”

In this paper a novel high temperature microencapsulated phase change material (MEPCM) based on paraffin as the core material and MF resin as the shell material has been developed with the in-situ polymerization method for solar hot water storage application. The results showed that the type of emulsifier could influence core material content, the encapsulation efficiency as well as the latent heat capacity. Based on the results and analysis the study has shown that energy storage density could be increased by as much as 59% if 60wt% of MEPCM 1 was to be used in the proposed compacted MEPCM-water bed system.

“…Various researchers have also explored the possibility of using phase change materials (PCMs) as heat storage media since they have much higher energy storage capacity and energy storage density than water [2,[10][11][12][13]. For instance, Murray and Groulx [10] evaluated a PCM based TES system and achieved about 44.3% increase in energy storage density as compared with water based system.…”

In this paper a novel microencapsulated phase change material (MF-3) has been developed and tested for solar assisted hot water storage systems. Even though the morphology of the sample was affected by the type of emulsifier used for fabrication it recorded the highest energy storage capacity of 126 kJ/kg with encapsulation efficiency of 97.4% as compared with other developed samples. For the purpose of assessing its thermal effectiveness it was theoretically evaluated in a compacted fixed bed TES unit and found to be capable of achieving a higher energy storage density as well as relatively smaller physical storage size than water based system. Despite the overall effective thermal conductivity being slightly less than water, its value was still about twice as high as most current PCM storage units. Experimental evaluation is therefore strongly encouraged.
