Thermal energy reservoir capacities for solar absorption cooling systems

It is essential to incorporate both hot and cold energy storage for a solar absorption cooling system in order to maximize the saving of conventional electrical power. The paper correlates the thermal energy storage requirements with the daily cooling demand pattern of a building. The other parameters which affect the choice of the two storage volumes are the effective sunshine hours, the chiller cooling capacity, its daily operation period and the two storage temperature differentials. The results have been obtained in a generalized manner and applied to an actual building in Kuwait.
