“…Rucevskis et al [141] designed a PCM-based active TES system for cooling multistory residential buildings. The TES system is integrated under the concrete ceiling inside the building to cool the PCMs (paraffin RT22HC) at night through cold water flowing in a capillary system contained in the energy storage unit.…”

Thermal energy storage based on phase change materials (PCMs) can improve the efficiency of energy utilization by eliminating the mismatch between energy supply and demand. It has become a hot research topic in recent years, especially for cold thermal energy storage (CTES), such as free cooling of buildings, food transportation, electronic cooling, telecommunications cooling, etc. This paper summarizes the latest research progress of the PCMs-based CTES. Firstly, the classification of PCMs for low temperature storage is introduced; the thermal physical properties (e.g., phase change temperature (PCT) and latent heat) of suitable PCM candidates (−97 to 30 °C) for CTES are summarized as well. Secondly, the techniques proposed to enhance the thermal properties of PCMs are presented, including the addition of nanomaterials, the microencapsulation and the shape stabilization. Finally, several representative applications (−97 to 65 °C) of PCMs in different CTES systems are discussed. The present review provides a comprehensive summary, systematical analysis, and comparison for the PCMs-based CTES systems, which can be helpful for the future development in this field.

“…Ručevskis et al proposed panels or storage units containing capillary mats with PCMs, which accumulate energy by means of a night cooling system through natural air currents. The system is capable of absorbing daily thermal loads inside the room [43]. Ning et al experimented with panels containing a thin layer of air, obtaining high efficiency when applying cooler water [44].…”

The present study focuses on the application of large-format thermal ceramic conditioning panels (TCPs) containing polypropylene (PPR) capillary tube mats in dwellings on the Mediterranean coast. The thermal and energy behaviours were examined once the underfloor heating was installed, and they were compared with an alternative wall application. The system was implemented in a single-family house located on the Spanish Mediterranean coast. After having monitored the house during a complete one-year cycle, the annual energy demand was quantified using the Design Builder tool. TCP panels applied to radiant floors reduced energy demand by 5.15% compared to the wall-layout alternative. Significant reductions in CO2 emissions were also achieved, as well as a 25.19% reduction in energy demand compared to convection systems. The incorporation of 24 m2 of solar thermal panels into the system, combined with solar cooling systems based on lithium chloride, was also analysed. A reduction in energy demand of 57.46% was obtained compared to all-air convection systems. Finally, the amortisation periods of the investments in TCP panels and solar panels were calculated and compared to a convection system. Underfloor TCP panels proved to be more cost-effective than a wall installation. The additional cost of EUR 21,844 could be amortised over approximately 14 years with the radiant underfloor TCP system, while the wall TCP would be amortised over 17.4 years.

“…Another application of PCMs in building energy savings by using -encapsulated PCMs (Nano-PCM) and shape-stabilized PCMs is described by Wijesuriya et al [3]. Also, Ručevskis et al [4] presented a parametric study and design optimization of a PCM thermal energy storage system with active control for cooling buildings and reported that optimized cases could reduce the indoor air temperature by 9.5 ͦ C, on average. Yang et al [5] used a double PCM with suitable thermal properties using lauryl alcohol and stearic acid with nanoparticles (LA-SA/Al2O3) for cooling and heating systems and found that 0.5% volume fraction of Al2O3 nanoparticles can improve the thermal conductivity of LA-SA by about 43%.…”
