How Does Geothermal Heat Pump Work?

If you are thinking of energy efficient mediums to heat and cool your home, you will be surprised to know that the solution lies buried deep inside the ground. It is the geothermal heat pumps. They are one of the efficient modes of heating and cooling your home which can reduce the monthly utility bills to a large extent. As far as the working principle of geothermal heat pumps are concerned they work in the same principle as conventional heat pumps. It uses high pressure refrigerant to transfer heat from indoors and outdoors. However, the difference between geothermal heat pumps and conventional heat pumps is that conventional heat pumps gather and get rid of heat through the outside air while the geothermal heat pumps transfer heat through long loops of liquid filled pipes buried in the ground.

Here, it must be noted that our ground absorbs around half of the solar energy that our planet receives. Hence, the earth remains at a constant and moderate temperature below the surface throughout the year. On the other hand, the air temperature varies greatly during the summer and the winter season, as a result of which air source heating and cooling is not a much efficient system. The geothermal heat pumps takes the advantage of the constant temperature of the earth and uses a piping system known as the loop to heat and cool your homes. Water circulates within the loop exchanging heat between your home, the ground source heat pump and the earth.

When it comes to cooling your home with the help of geothermal heat pumps, it removes heat from your home and transfers it to the earth which is relatively at a constant temperature. As the temperature of the earth stays constant, it has been seen that ground source heat pumps or geothermal heat pumps are more efficient than the conventional heat pumps or the air conditioner. On the other hand, when heating of your home with the help of geothermal heat pump is required it extracts heat from the ground and transfers it to your home.

Geothermal heat pumps uses two kinds of loop systems. One is the closed loop system and the other is the open loop system. The closed loop systems circulate a water based solution through a collection of small diameter, high density polyethylene underground pipes. On the other hand, open loop systems are used when there is abundant source of water which is low in minerals. These systems use groundwater from a well as a direct energy source.

Now let us have a look at the advantages of geothermal heat pumps. First of all, they are environment-friendly and cost-effective. As has been found out geothermal heat pumps reduce the usage of electricity which in turn decreases the use of coal as well. At the same time, geothermal heat pumps also reduce the chances of acid rain, air pollution, greenhouse effect or global warming. This becomes possible because geothermal heat pumps do not involve the burning of any kind of fossil fuels.
