What is Direct Exchange (DX) Geothermal Heating and Cooling & how does it work?
Geothermal is an alternative energy source that takes the heat from the earth, where the temperature is a constant 55 degrees, and uses that energy to heat and cool your home or business.
In the DX Geothermal system, copper tubing is placed in the ground in a closed loop and filled with refrigerant. The refrigerant circulates through the tubing, exchanging heat with the soil through the walls of the copper.
In winter, the refrigerant is taken from the ground and put under pressure, which can cause it to rise from 50 to 120 degrees. This 120-degree refrigerant is then used to heat your radiant or domestic hot water, or sent to your air handler, where it is converted to clean, hot air that is sent throughout the ductwork in your home.
In summer, the system runs in reverse, sending cool air though your duct system and removing humidity throughout your home.
DX systems can also be used to heat water in your home, for domestic hot water as well as for use in radiant heating applications.
