Abstract


Commercial buildings that have electrical energy needs above 150 kVA with power consumption imposed by the electricity system at peak load time (WBP). energy consumption in the Indonesian commercial sector starting in 2011 has increased 17.11% because the human population is increasing and the rapid development of building infrastructure. In this research, the (HVAC) Water coold chiller system is combined using cold thermal energy storage (CTES). CTES is an energy storage method, which can reduce the electricity consumption of the chiller. By shifting the peak load time this study uses full storage mode. This research method is conducted using simplex linear programming. Using CTES results in electricity tariffs that save 16.6% compared to conventional cooling systems.

 

Keywords : Electric energy consumption, Cold thermal energy storage, simplex liniear programming
