    5. 5. Ground Loop Temperature Profile T fluid = 9600’ T ideal = 32,960’
    6. 6. The earth is like a solar battery absorbing nearly half of the sun’s energy. The ground stays a relatively constant temperature through the seasons. 45% absorbed by ground Space Atmosphere Earth U.S. Dept. of Energy Passive geothermal gradient
    7. 7. It’s a Heat Source in Winter… 0  F  in winter 70  F A Geothermal System cools the ground in winter & transfers the heat into the building… 40-60  F Insulating layer of earth 2. How Does It Work? It’s a Heat Source in Winter 0°F in Winter Sinusoidal temperature layer of earth Heats the building in winter by absorbing heat from the ground 40 °F -60°F Ground Temperature 70°F Space Temperature
    8. 8. It’s A Cool Place to Dump Heat in Summer 95  F in summer 70  F 40-60  F … and cool the building in summer by rejecting heat to the ground Insulating layer of earth 2. How Does It Work? 98°F in Summer Cools the building in summer by rejecting heat to the ground It’s a Source to Reject Heat in Summer 40°F-60°F Ground Temperature 70°F Space Temperature Sinusoidal temperature layer of earth
