ANALYSIS OF REFRIGERATION ELECTRICITY CONSUMPTION REDUCTION AND PHOTOVOLTAICS AREA ANALYSIS FOR AIR COOLED CHILLER

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.
