RESUMO

The present work looked for to get of a detailed form the similar process of icing in the interior of spherical capsules and geometrias for the storage of thermal energy being used water and water-polietilenoglicol as PCM. A composed group of benches of test of a controlled tank of cooling and with precision was mounted of ±1 ºC. Capsules used in the tests had been developed with thermocouples type T, calibrated and located in the center of the capsule to investigate the effect of the solidification of the material. The band of variation of temperature for the assays had been of 25 a 5 ºC. After that a transient in spherical coordinates is presented and simulated mathematic model using the approach for finite differences with the project of the movel scheme. The experimental results had been presented and argued some parameters such as: time for solidification, working fluid, concentration, capsule material , velocity and position of the solidification front and the size of the capsule in the thermal process of solidification. However, the together modeling with the experimental results had supplied parameters storing construction of a modular one for residential ends.
