“…Pentaerythitol solid-liquid phase change enthalpy was lower than equipment resolution, so it could not be measured accurately. On the other hand, DSC tests confirm the phase change temperature reported in the literature for myo-inositol (C 6 H 12 O 6 ) [25] as well as for polybutylene terephthalate (PBT) ((C 12 H 12 O 4 ) n ) [20]. The measured melting enthalpy of myo-inositol was 223 J/g, higher than the one reported in previous studies [25].…”

“…Nevertheless, their energy density, fast thermal response, and high operational power do not pay off the high cost of the material. Classified by phase change temperature, metal PCMs can generally be divided into three categories: low temperature (0-30 • C), middle temperature (40-200 • C), and high temperature (>200 • C) [20]. In this case, high-temperature phase change material is required in the 210-270 • C temperature range (Table 2).…”

Abstract:The improvement of thermal energy storage systems implemented in solar technologies increases not only their performance but also their dispatchability and competitiveness in the energy market. Latent heat thermal energy storage systems are one of those storing methods. Therefore, the need of finding the best materials for each application becomes an appealing research subject. The main goal of this paper is to find suitable and economically viable materials able to work as phase change material (PCM) within the temperature range of 210-270 • C and endure daily loading and unloading processes in a system with Fresnel collector and an organic Rankine cycle (ORC). Twenty-six materials have been tested and characterized in terms of their thermophysical conditions, thermal and cycling stability, and health hazard. Two materials out of the 26 candidates achieved the last stage of the selection process. However, one of the two finalists would require an inert working atmosphere, which would highly increase the cost for the real scale application. This leads to a unique suitable material, solar salt (40 wt % KNO 3 /60 wt % NaNO 3 ).

“…These metals are have high thermal conductivity, good electrical conductivity, low vapor pressure, low heat of fusion per unit weight but high heat of fusion per unit volume (duo to large density), and small volume change during phase transition [17]. Thus, if certain metal or metal alloy is used as a PCM, the heat transfer capacity will be improved significantly compared with traditional PCMs.…”

Various types of solid-liquid phase change materials (PCMs) have been reviewed for thermal energy storage applications. The review has shown that organic solid-liquid PCMs have much more advantages and capabilities than inorganic PCMs but do possess low thermal conductivity and density as well as being flammable. Inorganic PCMs possess higher heat storage capacities and conductivities, cheaper and readily available as well as being non-flammable, but do experience supercooling and phase segregation problems during phase change process. The review has also shown that eutectic PCMs have unique advantage since their melting points can be adjusted. In addition, they have relatively high thermal conductivity and density but they possess low latent and specific heat capacities. Encapsulation technologies and shell materials have also been examined and limitations established. The morphology of particles was identified as a key influencing factor on the thermal and chemical stability and the mechanical strength of encapsulated PCMs. In general, in-situ polymerization method appears to offer the best technological approach in terms of encapsulation efficiency and structural integrity of core material. There is however the need for the development of enhancement methods and standardization of testing procedures for microencapsulated PCMs. Abstract: Various types of solid-liquid phase change materials (PCMs) have been reviewed for thermal energy storage applications.

“…This observation can be exemplified by a comparison of average thermal conductivity data for organic materials (from 0. mal conductivity of selected low melting point metals or metal alloys (eg. from 8.1 up to even 86.9 W/mK) [10]. However, since no PCM could meet not only all, but even most of the expectations, the "advantages" and "disadvantages" of using metals or its alloys as PCMs need to be thoroughly analysed and weighed not to be overrated.…”

Abstract. This paper presents an experimental study performed with the general aim of defining procedures for calculation and optimization of shell-and-tube latent thermal energy storage unit with metals or metal alloys as PCMs. The experimental study is focused on receiving the exact information about heat transfer between heat transfer fluid (HTF) and phase change material (PCM) during energy accumulation process. Therefore, simple geometry of heat transfer area was selected. Two configurations of shell-and-tube thermal energy storage (TES) units were investigated. The paper also highlights the emerging trend (reflected in the literature) with respect to the investigation of metal PCM-based heat storage units in recent years and shortly presents unique properties and application features of this relatively new class of PCMs.Key words: latent heat storage (LHS), phase change material (PCM), metal alloy, middle melting point metal PCM.
