Abstract :
Thermal Energy Storage (TES) system is already well established and one of the most important methods of demand to reduce peak-cooling loads. This system is divided by two periods known as charging period and discharging period. Discharging period is starting from 7 a.m until 10 p.m. Charging period to produce ice is 10 hours from 10 p.m until 7 a.m with capacity rated 24 refrigerant ton (RT) of cooling capacity for each tank. Nowadays, the issue of cost in term of power consumption becomes an obstacle to implement this system. This paper presents the power consumption saving during charging period for TES system in Engineering Complex, UiTM Shah Alam Selangor. The data obtained were observed and analyzed in order to saving the power consumption. In conclusion, there are some calculations that including with Tenaga Nasional Berhad (TNB) tariff to show the comparison in term of power consumption during charging period and electricity bill for a month between actual design, current design and propose design.
