Feasibility study of domestic cooling storage balls to reduce the energy cost of central air conditioning system

Abstract

Although cooling storage system used broadly in the world, it is rarely applied inViet Nam due to their high import expense that increase the initial cost. For that reason, in this article,we study on theories, and experiments about cooling storage sphere with expect to create the base forpopulising it in our country. That will contribute the efficiency of energy using to our country.
