Geothermal Heat PumpMadison Sorel and Madeline Cudmore

How It Works Anti-freeze/water in boreholes (heat exchanger).

Grout around boreholes- helps heat transfer.

Cold air from house is taken through hot pipes.

Reversible direction for seasons.

How It Works

Fans toggle direction/keep moving.

Ground water. More efficient (lowers around 40 degrees).

Any temperature of air/water to get heat.

Types

Energy Transformations Ground to boreholes: Rectilinear. Boreholes/pipes to pump: Mechanical, electrical, mechanical.

Air through fans: Rotational. Through house pipes: Electrical, mechanical, rotational, heat.

Through vents: Mechanical to heat. Reverse

Overview Borehole pipes take in heat from ground. Heat can be exchanged at any temperature.

Fans propel air through heated exchanger.

Heat exchanger channels into house system.

Used for hot water and house heat. Heat is fixed raised throughout house. Reversed for seasons.
