The
Northlands Geothermal Heating and Cooling Specialists!
Summit Mechanical Service
also provides Geothermal Heat Pumps as a means of heating and cooling your
new or existing home.
Geothermal heat pumps are similar to ordinary heat pumps,
but use the ground instead of outside air to provide heating, air
conditioning and, in most cases, hot water. Because they use the earth's
natural heat, they are among the most efficient and comfortable heating
and cooling technologies currently available.
In the heating mode,
the water circulating in the earth loop is colder than the surrounding
ground. This causes the water to absorb energy, in the form of heat, from
the earth.
The water carries this energy to the
heat exchanger in the pump.
In the heat exchanger, refrigerant absorbs the heat energy from the
water. The water now leaves the heat exchanger at a colder temperature,
and circulates through the earth loop to pick up more energy.
The
refrigerant gas, which contains energy gained from the earth loop, travels
from the heat exchanger to the compressor. In the compressor, the
refrigerant temperature rises to 160°. From the compressor, the
superheated refrigerant travels to the air heat exchanger.
Here, the
heat pump's blower circulates air across the air coil, increasing the
temperature of the air, which is blown through ductwork to heat the home.
After refrigerant releases its heat energy to the air, it then flows to
the earth loop heat exchanger to start the cycle again.
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 from traveling through
the ground now flows to the heat exchanger in the heat pump.
In the heat exchanger, hot refrigerant gas from the compressor releases its
heat into the water. This causes the water to increase temperature, which it
releases to the ground.
The
refrigerant, which has released its heat energy and became a cold liquid,
now travels to the heat exchanger. Here the heat pump's blower circulates
warm, humid air across the cold air coil. The air is then blown through
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 then flows to the earth loop heat
exchanger to start the cycle again.
