Experimental thermal performance of deionized water and iron oxide nanofluid for cold thermal storage.

Phase change materials enhance the thermal comfort of buildings by utilizing stored thermal energy. In large air-conditioning systems, ice storage plays a crucial role in managing peak power loads. This experimental study explores the freezing characteristics of deionized water containing suspended iron oxide nanoparticles in spherical containers for cold storage.

Experimental performance of a finned spherical container in cold thermal storage for tropical buildings.

The heating and cooling of buildings consume almost 40% of global energy consumption. Cooling building spaces require more input energy compared to heating in tropical buildings. The power tariff varies according to the base and peak demands.
