Condenser Water

Temperature Reset

In certain chiller water systems, energy can be saved by resetting the condenser water temperature down to maximum evaporative cooling and lower chiller compressor energy.

Condensed Water

CONSIDERATIONS

  • Must be a variable speed chiller(s).
  • Must be a water-cooled chiller system.
  • More impactful energy savings in drier climates.
  • Less economic savings in areas with expensive water supply.
  • Consult chiller manufacturer on equipment ability to support lower condenser water temperatures.

KEY PERFORMANCE INDICATORS (KPIS)

  • 0.5-1 point energy use intensity {EUI} reduction potential
  • 0.5% sitewide electric savings
  • 0.5-1.5 year simple payback
