Résumé
In this study, we examined the feasibility of using cold ice as a medium to store the cold energy in the cold season and use it during the hot season in locations which experience both cold and hot seasons. We studied a cylindrical storage tank, two meters in diameter and two meters in length, wrapped with conventional insulation providing R-50. We assumed that the contained ice reaches -25 ℃ during the winter time and it was assumed to be exposed to the warm temperature of 18 ℃ for six months prior to being required for cooling. We used COMSOL Multiphysics to model the heat transfer in a three dimensional configuration. The results showed that 40 percent of the stored cold energy would be depleted during the six month period prior to the hot season. It would take 43 days for the ice in the tank to reach the melting point after consuming the sensible stored cold, and the melting process begins after that. The remaining energy is able to provide the cooling energy for almost full 24 days for an R-2000 2-story detached house located in Ottawa, Ontario.
