How It Works
Working Principle of Geothermal Heat Pumps
Geothermal heat pumps (GHP) deploy an entirely different working model compared to traditional HVAC systems. Considering the most energy-efficient technologies for providing residential heating and cooling services, GHPs exchange heat with the ground to heat or cool your building through vapor-compression refrigeration cycles.
Concept of Source & Sink
Unlike the air temperature, which keeps fluctuating, the temperature beneath the earth’s crust remains fairly constant and undisturbed. GHPs use the earth as a heat source in winter and as a heat sink in the summer. They provide winter heating by extracting heat from a source and transferring it to your building. The same process is reversed in the summer, where the heat pump extracts heat from your building and transfers it to the ground to keep your room temperature optimal.
Like GHPs, water source heat pumps also ensure a high coefficient of performance by rejecting heat in a cooling cycle through a pond, a lake or a cooling tower, thus keeping your building cool and comfortable.
Advantages of GHPs
The overall initial installation cost of GHPs is several times higher compared to traditional HVAC systems, given the increased cost of insulation and the fee charged by drilling contractors to drill holes up to 300 feet deep. However, our heat pumps are up to 65 percent more efficient than traditional HVAC units and repay their high installation costs in energy savings over time. Our high-quality products also have extremely long-life spans while reducing carbon emissions that harm the environment.
