The Secret To Heating And Cooling Energy $avings
Is Just Beneath Your Feet
Similar
to an air source heat pump, a geothermal heat pump transfers heat through the
refrigerant system into, or out of, the conditioned space. A geothermal heat pump's heat transfer cycle
happens underground. Where as an air
source heat pump does this in the atmosphere.
In the Mid-West, ground below the frost line maintains a constant
temperature of about 52 degrees, and the outside air can drop well below 0
degrees. Thus making an air source heat
pump less efficient below 20 degrees.
The geothermal heat pump utilizes the 52 degree temperature year round
to pick-up or drop-off heat to condition your home or business. There are a few different methods available
to transfer the heat to or from the earth.
The most common way is with an underground loop system that is installed
up to 250 feet under ground. Another
common method is using an actual well, called a pump and dump. We will use a loop system for demonstration
purposes here, and a full examination will be made of your property to
determine the right installation method for your system. The loop system is installed via drilling
holes, similar to a well, and inserting poly tubing for the water to circulate
through.
During the geothermal heat pump's heating and cooling
cycles, the water circulating into the heat pump crosses paths with the
refrigerant system through a coil-inside of a coil. In the cooling mode, the water circulating in the earth loop is
warmer than the surrounding ground.
This causes the water to release energy, in the form of heat, into the
earth. The water, now cooler, flows to
the heat exchanger inside the heat pump.
In the heat exchanger, hot refrigerant gas from the compressor releases
its heat to the water. This causes the
water to increase in temperature, which it releases to the ground. The refrigerant, which has released its
energy and became a cold liquid, now travels to the air heat exchanger. Here, the heat pump's blower circulates warm,
humid return air across the cold air coil.
After blowing across the air coil, the air is cooled and
dehumidified. The air is then blown
through the ductwork to cool the home.
The refrigerant in the air coil picks up the heat energy from the air,
and travels to the compressor. When the
refrigerant leaves the compressor, it flows to the earth loop heat exchanger to
start the cycle again. This process is
reversed in the heating stage by the touch of a button.
