“…They can take advantage of latent heat during phase change at a fixed temperature [1][2][3][4]. The thermal energy storage by PCMs can resolve the time mismatch between the energy supply and the consumption of energy, and play the role in switching peak load and increasing efficiency of energy utilization.…”

Microencapsulated phase change materials (microPCMs) have been widely applied in solid matrix as thermal-storage or temperature-controlling functional composites. The thermal conductivity of these microPCMs/ matrix composites is an important property need to be considered. In this study, a series of microPCMs have been fabricated using the in situ polymerization with various core/shell ratio and average diameter; the thermal conductivity of microPCMs/epoxy composites were investigated in details. The results show that the microPCMs have smooth surface and regular global shape with compact methanolmelamine-formaldehyde shell. The shell thickness does not greatly influence the phase change behaviors of PCM. Moreover, smaller microPCMs embedded in epoxy can improve the thermal transmission ability of composites. The effect of thermal conductivity of composites can be improved with higher volume fraction (10-30%) of microPCMs; and smaller size microPCMs with the same content of PCM may also enhance the thermal transmission area in matrix. Modeling analysis of relative thermal conductivity indicates that mixing higher thermal conductivity additive in PCM or matrix is an appropriate method to improve the thermal conductivity of microPCMs/matrix composites.

“…For example, thermoelectric conversion for wall heat loss, [6][7][8][9] pre-heating of materials and steam generation for fluid sensible heat and radiation, etc. One of the attracting technologies is latent heat storage [10][11][12][13][14] that once stores thermal energy as latent heat of melting and then supplies it to the distant place with time-shift and flattened temperature level. Regarding the temperature level of the waste heat, high and middle temperature waste heats is able to be recovered fairly easily because the driving force in heat recovering process can be set high.…”

“…Performance of a direct contact latent heat energy storage system during the discharging process has been investigated using a storage medium of sodium thiosulfate pentahydrate [3]. The thermal and flow behavior in a transheat (TH) container has been examined, in which the solidification and melting of the PCM were observed directly using a two-dimensional roundly sliced model [4]. The improvement in heat storage performance of a direct contact heat exchanger using the phase-change material erythritol and heat transfer oil was described [5].…”

Today, latent heat storage technology has advanced to allow reuse of waste heat in the middle-temperature range. This paper describes an approach to develop a latent heat storage system using middle-temperature waste heat (~100˚C -200˚C) from factories. Direct contact melting and solidification behavior between a heat-transfer fluid (oil) and a latent heat storage material mixture were observed. The mixture consisted of mannitol and erythritol (C m = 70 mass %, C e = 30 mass %) as a phase-change material (PCM). The weight of the PCM was 3.0 kg and the flow rate of the oil, f oil , was 1.0, 1.5, or 2.0 kg/min. To decrease the solidified height of the PCM mixture during the solidification process, a perforated partition plate was installed in the PCM region in the heat storage vessel. PCM coated oil droplets were broken by the perforated partition plate, preventing the solidified height of the PCM from increasing. The solidification and melting processes were repeated using metal fiber. It was found that installing the metal fiber was more effective than installing the perforated partition plate to prevent the flow out problem of the PCM.
