“…To the best of our knowledge, a single system enabling all these modes has not been yet realized. The published systems investigated use either PCMs integrated in air channels [7] or in water circuits [9] with specific applications such as free cooling and air conditioning for the first approach and thermal storage for water heating for the second one.…”

We integrated 18 kg of PCM in 80 cells of a plate heat exchanger which were placed between a water charge and an air discharge circuit fed by the air renewal. The 0.1 m3 thermal battery can replace radiators to heat and cool, store heat and cold and perform air renewal independently for each room. The narrow PCM cells and the relatively large temperature difference between the PCM with fusion temperature of 25°C and the renewed air allowed to achieve average discharge powers of 300W and 440W for heating and cooling respectively. The integrated total heat and cold storage capacities were found to be 1.5 kWh and 1.8 kWh respectively. By replacing each radiator of a house with such a battery substantial thermal storage can be achieved. The liquid thermal battery, cooled with outdoor air of 17°C, completely solidified in less than 7h. This means that cool summer nights can charge the PCM to cool the room the following day.

“…In these applications, the PCM is charged and discharged directly by the thermal equipment (e.g., vapor compression system or electric resistance heat) to shift electric loads associated with each thermal end use. [26][27][28][29][30][31][32][33][34][35][36][37][38][39] A common dynamic application is the use of campus-scale cold storage, using large chillers with ice or chilled water as the storage medium. [40] While this is a cost-effective TES solution for campus systems and large commercial buildings, there is a need to integrate TES into smaller, modular building systems, as all residential buildings and most commercial building floor space are conditioned by smaller packaged air conditioners and heat pumps.…”

Phase change materials (PCMs) can enhance the performance of energy systems by time shifting or reducing peak thermal loads. The effectiveness of a PCM is defined by its energy and power density-the total available storage capacity (kWh m −3 ) and how fast it can be accessed (kW m −3 ). These are influenced by both material properties as well as geometry of the energy systems; however, prior efforts have primarily focused on improving material properties, namely, maximizing latent heat of fusion and increasing thermal conductivity. The latter is often at the expense of the former. Advanced manufacturing techniques hold tremendous potential to enable co-optimization of material properties and device geometry, while potentially reducing material waste and manufacturing time. There is an emerging body of research focused on additive manufacturing of PCM composites and devices for thermal energy storage (TES) and thermal management. In this article, the fundamentals and applications of PCMs are reviewed and recent additive manufacturing advances in latent heat TES for both the PCM composite and associated heat exchanger are discussed. A forward-looking perspective on the future and potential of PCM additive manufacturing for TES and thermal management is provided.

“…They are used in multiple fields: solar energy (solar water heating, solar air heating [2,3,4], solar power plants [4]), construction of passive and active energy-storage systems [5], photovoltaic panel cooling [6], electronics [7], automotive industry [8], space heating and domestic hot water systems [9], space cooling systems [10], spacecraft industry, food industry, for biomedical appliances and intelligent textiles. The first studies in the literature dealing with PCM are dated back to the '40s of the preceding century [11], but only the energy crisis during the '70s led to their utilisation as thermal energy storages (TES) that can release sensitive heat (SH) or LH, and visibly increased PCMs' importance for energy management [12,13]. PCMs can be grouped based on their origin as organic, non-organic or eutectic mixtures.…”

Values of energy supply and demand vary within the same timeframe and are not equal. Consequently, to minimise the amount of energy wasted, there is a need to use various types of energy storing systems. Recently, one can observe a trend in which phase change materials (PCM) have gained popularity as materials that can store an excess of heat energy. In this research, the authors analysed paraffin wax (cheese wax)’s capability as a PCM energy storing material for a low temperature energy-storage device. Due to the relatively low thermal conductivity of wax, the authors also analysed open-cell ceramic Al2O3/SiC composite foams’ (in which the PCM was dispersed) influence on heat exchange process. Thermal analysis on paraffin wax was performed, determining its specific heat in liquid and solid state, latent heat (LH) of melting, melting temperature and thermal conductivity. Thermal tests were also performed on thermal energy container (with built-in PCM and ceramic foams) for transient heat transfer. Heat transfer coefficient and value of accumulated energy amount were determined.
