Inside a Geothermal Heat Pump

01/31/2011

Recently, many inquisitive Michiana residents have asked Crystal Valley Comfort about geothermal. Sure, geothermal heat pumps use the earth to condition your home... but how do they do it?

This fascinating system works thanks to one simple principle: Given the opportunity, heat flows towards areas that are cooler. That's why an ice cube melts and it's the mechanism behind a geothermal heat pump. Here's how geothermal works :

Combustion is not the source of heat in a geothermal system. It simply collects and moves it using the principle stated above. In order to carry heat energy from one major component of the system to another, a special liquid called refrigerant is used. The refrigerant is pumped throughout the system by a powerful centrifugal pump called a compressor.

During the winter, heat from the earth is absorbed into the loop water and carried up to the coaxial coil. Again, the inner tube of the coil contains water from the loop while the outer tube contains cold refrigerant. The loop water passes its warmth through the walls of the coil and heats the refrigerant. The refrigerant carries that heat into the compressor where it’s put under a large amount of pressure - making it exceedingly hot.

To cool your home, the system literally reverses the entire process using a reversing valve. Refrigerant flows in the opposite direction and order of components.
