Abstract
Abstract This paper presents the feasibility of utilizing thermal energy storage systems in reducing both the initial and running expenses of chiller systems in large mosques. The study focused on the great mosque in the city of Mosul as a model. Two load profiles are considered, the occasional and the normal profiles with three different partial storage control strategies. The conventional strategy is also considered for the purpose of comparisons. From the results, it can be concluded that, the amount of the shifted load from the on-peak period for the occasional profile is equal to 45.2%, 24%, and 39.1% for the three control cases respectively. Up to 74% reduction in the on-peak power consumption can be achieved with a total shifted power, (from the on-peak to the off-peak periods) of up to 47.2%, which will add significantly to the total cost reduction. For the normal profile, the amount of the shifted load from the on-peak period is equal to 9.8%. The peak power consumption is reduced by 33.1%, and about 10% of the consumed power is shifted to low price period. Key words: A/C systems, refrigeration systems, thermal energy storage
