Abstract

The purpose of this study is to find out the efficiency improvement of the cooling system and cut-off of cooling energy consumption by changing the design method of the cooling tower system applied in Korea. The quantitative analysis was carried out on the cooling energy consumption saved by changing the Korea Standard design temperature of cooling tower system through EnergyPlus simulation. As a result of the simulation, when the condenser water temperature difference from the existing cooling tower design standard is 5K to 7K, the annual cooling energy consumption is reduced by 27,084 kWh, approximately 7.6%. Also, additionally, when the condenser water leaving temperature form the existing cooling tower design standard is 32°C to 23.9°C according to ASHRAE 90.1, the annual cooling energy consumption was reduced by 59.419 kWh, and approximately 16.7%.
