How Does Geothermal Cooling Work?
One flip of a switch turns your geothermal heating system into a geothermal cooling system. The geothermal unit draws heat from your home and carries it, by way of the “loop” back into the earth. In fact, the geothermal unit operates on the same principle as your refrigerator but instead of putting the heat into your home, it puts it in the ground. A small compressor on the back of your refrigerator constantly removes heat from the refrigerator. All year round, the geothermal system heats your water. During both the summer and winter months, some of the heat being moved is diverted and put to good use in your hot water tank. This allows the earths energy from your back yard to heat about 35% of your hot water.FREE! Many homeowners realize well over a hundred dollars each year in savings from this extra geothermal system benefit. With a geothermal system, the source of your heating and cooling is free. The only energy required is the electricity needed to operate the geothermal unit. Th
Geothermal cooling is a process by which shallow ground is utilized within a system to regulate temperature. The upper 10 feet of the earth’s surface holds a stable temperature between 50° to 61°F (10° to 16°C). This stable temperature is harnessed, using a geothermal device, to draw heat energy out of a system and thus transfer the cool temperatures into a warmer area. Surface temperature has almost no effect on the ground underneath the frost line. Using this knowledge, a pump can be placed under the ground, in an area such as a basement, that effectively pulls the cool sustaining temperature from the ground. This device is connected to a loop of copper tubing or high-density polyethylene, which is literally buried underneath the earth’s surface. This loop contains a refrigerant that is pumped through the tubing, exchanging the warm energy in the building with cooler energy in the ground and acting almost like a heat sink. This process is known as direct exchange and is very effectiv
Posted on February 22nd, 2009 alanjacobson No comments If the whole premise behind geothermal (or “ground source”) heat pumps is tapping into the natural and renewable heat produced just under the earth’s surface, how can they be used to cool your home as well? The secret lies in the loop involved in bringing the heat up from the ground. Simply put, that loop can be reversed! In this case, the geothermal system literally pulls the heat from your home and returns it to the ground! All that is left behind is cool air. It is vital to check with your ground source or geothermal heat installer to make sure the system s/he is going to install can effectively cool your home.
