Thermal performance of cool storage in packed capsules for air conditioning

Numerical investigation of packed bed storage unit filled with PCM encapsulated spherical containers – A comparison between various mathematical models

“…The result was characterized based on five independent dimensionless parameters, such as effective water-to-coolant heat capacity ratio, effective ice-to-coolant heat capacity ratio, Stanton number, Stefan number and Peclet number. Comparisons of the numerical results show good agreement with the experiments, against their previous work on a one dimensional lump model [5]. Watanabe et al [6] developed and studied a heat storage system consisted of horizontal cylindrical capsules filled with three types of PCM with different melting temperature.…”

Effect of fill volume on solidification characteristics of DI (deionized) water in a spherical capsule – An experimental study

“…Chen and Yue [5] investigated the thermal performance of icewater cool storage in packed capsules for air conditioning and pointed out that more than 75% of the cool energy was stored by water-ice latent heat and the rest was stored in water or ice as sensible heat. They concluded that for real application, the efficient cool storage should not utilize the ice sensible heat due to its low energy intensity and low cooling rate.…”

Performance analysis on industrial refrigeration system integrated with encapsulated PCM-based cool thermal energy storage system

“…Various heat transfer enhancement methods for latent heat storage systems for domestic hot water applications and heat transfer characteristics of PCM during solidification were investigated by , . Chen and Yue (1991), and Chen et al (2000) investigated the thermal performance of cold storage tank during charging process utilizing cylindrical capsules with varying inlet coolant temperature and flow rate. Their results showed that, it is possible to store the cold energy fully in the form of latent heat when the inlet coolant temperature is set below the temperature with 100% nucleation probability.…”
