NRG Skybox Data Center in Katy, Texas. Twin 400 ton Trane Air Cooled Chillers fitted with EvaporCool. Energy Savings reduced PUE(Power Utilization Effectiveness) to 1.3 ratio at full load.
The Evaporcool system uses approximately 1.9 gallons of water for each kWh saved, saving approximately 90% of water usage while also saving electricity.
Based on national averages, on a 75-ton HVAC unit, the Evaporcool system will use $78 of water in a year, while saving more than $7,000 annually in electricity.
The National Renewable Energy Lab (NREL) reports that U.S. electricity production consumes more than 20 gallons of water per kWh created.”
Other studies confirm this water usage and state that depending upon the power plant type, the water usage can range from 10 gallons to 25 gallons of water consumed per kWh created.
