Geothermal cooling
Geothermal cooling systems circulate water below ground through a series of pipes where it is cooled by the surrounding earth and subsequently pumped back to the surface. Where feasible, such systems can replace or augment existing refrigeration systems, leading to significant energy savings. In 2005, Aohata Corporation, a jam manufacturer in Japan, began operating a new geothermal cooling system that provided its facility with 260 kW of additional cooling capacity. The company reported that the geothermal cooling system uses only about 25% of the electricity required by a traditional refrigeration system.
