Annual Energy Use with Geothermal Heat Pumps is 44% Less than with a Variable Refrigerant Flow System
PRESS RELEASE from
Geothermal Exchange Organization
Dec. 15 – Definitive scientific research has shown that a geothermal heat pump system offers far more efficiency in a large commercial building than a variable refrigerant flow system.
In January 2013, the Geothermal Exchange Organization (GEO)—with financial assistance from Southern Company—contracted a research team from Oklahoma State University and Oak Ridge National Laboratory to evaluate the relative performance of GHP vs. VRF heating and cooling systems installed at the American Society of Heating Refrigeration and Air-conditioning Engineers (ASHRAE) International Headquarters Building in Atlanta, GA. (Editor’s Note: ASHRAE provided data for this study, but the organization does not endorse, recommend or certify any equipment or service used at ASHRAE International Headquarters).
