United States-MEPS-Electric chillers - 2003

Source: International Energy Agency
Last updated: 05 November 2017

The Federal Energy Management Program (FEMP) set efficiency requirements for air-cooled and water-cooled electric chillers. Product performance must be measured in accordance with AHRI 550/590 test procedures. Free-cooling and combination chiller-heat pump units are excluded.
