Energy saving of cooling tower replacement by a mathematical model

Abstract

The cooling tower replacement of chiller system is effected to energy saving of chiller because of condenser’s heat transferring was improved. The evaluation of energy saving from replacement the new cooling tower could be low accuracy because the old cooling tower has been rejected. This research was study the relativity between old 1,250 ton of cooling tower and 1,000 Ton of chiller by mathematic model to use as base line. When replace new cooling tower could be measuring the energy saving because the base line of old system in mathematic model so that would be more accuracy in energy saving evaluation. The result of mathematic model creation for old system found accurate 2.7 of CVRMS. The mathematic model equation could be predicted the energy saving when replace new cooling tower, the potential energy saving was 693,863 kWh/year.
