ELECTRICAL CONSUMPTION BALANCE OF CHILLERS COOLING LOAD

Air condition systems is the largest consumer of electrical energy in industrial factories and commercial buildings. It account over 60% of electrical power use in buildings. In chilled water plant systems the chiller and other components electrical load fluctuates, this lead that all chillers change their capacity to provide the required load. None of the chillers are in a base load / trim sequence strategy . Chiller plant air condition system optimization becomes a priority efficiency upgrade , this reduces electrical energy usage and costs by 30% and improves plant reliability by running equipments more efficiently .In this study different recommendation of control steps and upgrades applied in the chiller plant system and sensors to work together around the clock to use the least electrical power consumption without any effect on performance .
