Abstract:
Water and electricity consumption are currently becoming one of the issues, especially
environmental issues that need to be prevented. By replacing water-cooled chillers
with air-cooled chillers, water consumption will be reduced to ± 0 m3 and electricity
consumption will also be reduced from 2.00.4296 kWh to 1.855.330 KWh. Because of
the reduction in electricity consumption, there will be a reduction in electricity cost
estimated at IDR 214.510.323 /year. In addition to analyzing the reduction in
electricity consumption from air-cooled chiller author installation, it also analyzes the
possibility of the application of photovoltaic panel to cover the air-cooled chillers
electricity consumption. Based on the calculation, the area needed for photovoltaic
panel is 5679,39 m2. By dismissing the cooling tower along with water cooled chiller,
there will be 9757,44 m2 available space for applying the photovoltaic panel.
