Summary This paper reviews the application of phase change materials (PCMs) for improving the performance of air conditioning systems. The different methods of integrating PCMs into air conditioning systems are presented. Moreover, the effects of PCM geometry, flow, and heat transfer characteristics on the performance of air conditioning systems and the potential use of PCMs in increasing the energy savings and coefficient of performance of air conditioning systems are also discussed. Recent studies on the thermodynamic (energy and exergy), economic, and environmental benefits of integrating PCMs into air conditioning systems are reviewed. Several methods for the preparation and optimal selection of PCMs are proposed to improve the performance of air conditioning systems, and then the challenges relating to PCM properties, optimal thickness, and PCM containers are highlighted. The economic aspects, humidity effect, life cycle assessment, and use of solid‐solid PCMs are cited as potentially important topics for future research.

“…The main methods have been reviewed for modeling and assessing performance of stratified thermal storage (Njoku et al 2014). Further, techno-economic assessments of heat and cold thermal storage systems have been applied, often using advanced methods like exergoeconomics (economics based on exergy) (Rosen 2011;Mosaffa and Garousi Farshi 2016). The economics of thermal storage systems in conjunction with cogeneration, trigeneration and DE have also been the subject of numerous investigations (Rentizelas et al 2009;Lozano et al 2009aLozano et al , 2010Balli et al 2010;Dominković et al 2015), including thermoeconomic analyses (Balli et al 2010) and economic optimization of designs (Lozano et al 2010).…”

The status and needs relating to the optimal design of community seasonal energy storage are reported. Thermal energy storage research has often focused on technology development and integration into buildings, but little emphasis has been placed on the most advantageous use of thermal storage in community energy systems. Depending on the composition and characteristics of a community, the most appropriate community thermal storage may differ from that for a single building. District energy systems usually link thermal users to cold supplies and/or heat supplies (e.g., solar thermal energy, geothermal energy from ground-source heat pumps or geothermal hot zones, industrial waste heat, thermal energy from cogeneration or trigeneration). It is demonstrated that the optimal integration of these technologies can be enhanced through the use of appropriate seasonal thermal energy storage and that community-level seasonal storage can facilitate the development of smart net-zero energy buildings and yield efficiency, economic and environmental benefits. Issues that need to be resolved to allow optimal solutions to be attained are described. Advanced tools are required for modeling, simulation, analysis, improvement, design and optimization, which incorporate advanced methods like exergy analysis. The most appropriate scale, number and type (e.g., sensible, latent, thermochemical) of thermal storages in a community need to be better assessed, and the appropriate time duration capacities for each determined in an optimal manner. This is particularly important since a combination of short-, medium-and long-term storage is sometimes required to yield the most benefits from community energy systems.

Abstract. PCM-based systems for cooling of building spaces are a developing area with great potential. Especially since cooling systems are becoming more popular resulting in increased demand for energy. The aim of this work is to analyse how application of phase change materials can support and improve cooling efficiency of air conditioning. Authors discuss and compare different types of PCM-based solutions.
