How Does A Geothermal Heat Pump Work?

A Geothermal Heat Pump Moves Heat Energy From One Place to Another.

A geothermal heat pump can help you save money on your energy bills. These units move heat energy from an area of higher heat energy to an area of lower heat energy. In the winter, a geothermal heat pump provides heat for your home.  In the summer, a geothermal pump draws heat out of your home.

Heat Exchange Process

The temperature under the earth’s surface is warmer than the outside temperature in the winter. A geothermal heat pump uses a series of underground pipes flowing with water and antifreeze to absorb the heat from the ground. The water mixture flows into the geothermal heat pump. This is where the heat exchange happens to move the heat out of the pipes into your house.

The heat pump has four basic components. In the evaporator, a liquid refrigerant absorbs the heat energy from the pipes. This causes the liquid to boil and evaporate and move into the compressor. The compressor increases the heat energy of the evaporated refrigerant. From the compressor, the evaporated refrigerant moves into the condenser. The condenser transfers the heat energy into the pipes that will carry the heat into your home. The evaporated refrigerant releases its energy and returns to a liquid state. The liquid refrigerant travels through the expansion valve, which releases the remaining pressure from the refrigerant and it goes back into the evaporator. This process gets repeated over and over again.

The process reverses to pull excess heat from your home when the weather is hot. If you want to learn more about installing a geothermal heat pump in your home, contact our office at (910) 485-5877.
