“…For example, the emulsion 42 developed by Xu et al [9] with tetradecane and water was stable for only 40-50s. The sample 43 tested by Schalbart et al [10] achieved a short period of storage stability at room temperature. 44 Vilasau et al…”

In this paper, a novel phase change material emulsion (PCE-10) consisting of an organic PCM (RT10) and water has been developed. Its thermophysical properties such as heat of fusion, viscosity and sub-cooling temperature have been established. The chemical stability during both storage and discharge periods have also been evaluated. The results indicate low sub-cooling temperature and relatively long period of stability without any sign of segregation but the viscosity was found to be much higher than that of water.Further improvement and experimental studies into its flow characteristics are therefore being encouraged. In this paper, a novel phase change emulsion material (PCE-10) consisting of an organic 6

“…Schalbart et al [46] used three different low energy methods (EIP, mixing film and PIT) to prepare tetradecane emulsions and found the PIT to be the most effective approach. During the preparation, all the components which were pre-mixed at room temperature were heated to 72°C, and then were cooled down to room temperature by adding 54g cool water.…”

“…The PCMEs can be considered as stable when neither distinct growth in droplet sizes nor phase separation occurred during the storage period, and in practical applications, it is tolerable when emulsions remained in dispersion and kept the heat capacity under the designed operational conditions [66]. Schalbart et al [46] tested tetradecane-in-water emulsions and achieved good storage stabilities against creaming at room temperature for six months. But Ostwald ripening destabilisation was still observed resulting in a slight increase in the droplet size.…”

Phase change material emulsions (PCMEs) are multifunctional fluids consisting of phase change materials (PCMs) and carrier fluids. PCMEs could be potential candidates as heat transfer media in heating, ventilation and air conditioning (HVAC) systems. This is mainly because PCME could take advantage of its high heat capacity to reduce flow rate and thus saving pumping power whilst delivering the same amount of cooling effect. PCME can also simultaneously act as cold storage to shift peak-load to off-peak time and improve the COP of systems. However, the optimum design of integrated system requires a good understanding of flow behaviour and heat transfer characteristics of PCMEs. In this paper, comprehensive reviews of their thermophysical properties and potential applications as thermal energy storage and as alternative heat transfer fluids in air conditioning systems have been carried out to establish their limitations for future research. systems.

“…Solid-liquid fluids, composed of phase change materials (PCM) dispersed in a carrying liquid, are relevant for secondary refrigeration because of the high energy density of PCMs. Ice slurries are the most common solideliquid fluids but their industrial applications (Guilpart et al, 2006) requires mechanical processes, as scraping or brushing surface exchangers, which increase energy losses (Schalbart et al, 2010). Gas hydrate slurries composed of a suspension of hydrate crystals in aqueous solution can also be used as secondary refrigerants (Fukushima et al, 1999) and can be produced by gas injection without mechanical processes (Fournaison et al, 2004;Jerbi et al, 2010;Delahaye et al, 2011;Jerbi et al, 2013).…”
