“…The results showed that the entire energy cost could be shifted to off‐peak times in terms of electric demand in winter by adding the PCM. Xia et al proposed a new double‐layer radiant floor system combined with organic PCMs, which could store amounts of energy during off‐peak hours that could be used during peak hours (Figure ). The PCM floor system operated well in both summer and winter.…”

This paper provides a review of the solid-liquid phase change materials (PCMs) for latent heat thermal energy storage (LHTES). The commonly used solid-liquid PCMs and their thermal properties are summarized here firstly. Two major drawbacks that seriously limit the application of PCMs in an LHTES system, that is, low thermal conductivity and liquid leakage, are discussed. Various methods for enhancing the thermal conductivity and heat transfer of solid-liquid PCMs are explained. Previous studies regarding formstable composite PCMs and microencapsulated PCMs are also presented. Furthermore, applications of the solid-liquid PCMs used in LHTES and thermal management systems are introduced and analyzed. Finally, future outlooks and research topics are proposed.

Summary This paper deals with the utilization of a renewable energy‐based integrated system with the latent heat storage option for building thermal management systems. Both energy and exergy‐based assessments of the current combined system are conducted. For this purpose, phase change material (PCM)‐embedded radiant wall heating system using solar heating and ground source heat pump (GSHP) is studied thermodynamically. Heat is essentially stored within the PCMs as used in the panels to increase the effectiveness. The stored heat is released when the solar energy is not available. In the thermal energy storage analyses, four different PCMs are considered. The present results show that the overall first ‐ law (energy) and second ‐ law (exergy) efficiencies of the PCM‐free radiant heating system are much lower than the case with the PCM‐embedded radiant heating system. Therefore, it is confirmed that the energy efficiency increases from 62% to 87% while the exergy efficiency rises from 14% to 56% with the option where SP26E PCM is employed accordingly.

In this study, a quick‐freezing plate filled with low‐temperature phase‐change material (PCM) with a mass fraction of 15% was applied in household refrigerator. A single smooth quick‐freezing plate significantly reduced the amount of time required for food to pass through the maximum ice crystal generation zone, and this amount of time was 1/6 or 3/5 of that for the refrigerator in natural convection or air blast freezing. The rate of water loss using air blast freezing was 4.26% compared with that of the a single smooth quick‐freezing plate at only 1.60%. For various thicknesses of the experimental pork, the quick‐freezing effect of the double‐layer surface plate was better than those of the other conditions. For pork thickness of less than 6 mm, the quick‐freezing effect of the single smooth surface plate was better than that of air blast freezing. Practical Applications In this study, a new quick‐freezing plate with a phase‐change material (PCM) was developed specifically for a domestic refrigerator. The quick‐freezing effect can be equivalent to that of air blast freezing if food thickness does not exceed the specified range. The plate in this study consisted of an aluminum lid, a plastic shell, a cold‐storage agent, and a cold‐storage bag.
