The Advantages of Geothermal Power for Air Cooling
September 2nd, 2010Geothermal power is described as the heat made in the earths core since the planets origin. This energy originates from radioactive decay of numerous minerals underneath the earths crust and also from the solar power absorbed by the earth’s surface area. The energy at present, is used in industries, commercial businesses and even in homes for numerous capabilities and is considered ecologically feasible as it uses minimal exhaustible resources of the earth. The thermal performance of this power is additionally high as little or no power conversion is needed during its use.
In recent years, geothermal power gains ground as it is being increasingly more utilized in heating and cooling of houses and offices. This process uses constant temperature of the earth to heat and cool houses and companies with 40-70% less power than traditional systems. While normal heating and cooling products burn fuel or consume electricity, the geothermal power uses a much lesser quantity of electricity only to pump out heat from the earth and then directly utilize the heat energy for air heating or cooling.
Geothermal companies offer ground source heat pumps, for air cooling and heating uses, which extracts heat from ground or groundwater, therefore lowering carbon dioxide emissions and electricity bills and increasing ecological sustainability.
Ground source heat pumps : Mode of action
Air cooling and heating by ground source heat pumps is a process that is very much in vogue in the developed countries and is attaining a certain level of utilisation in developing nations too. The regular heat of the earth, at about 10 feet below the earths surface, continues to be around 50F, that is utilized by these pumps for the purpose. Air or anti-freeze liquids are generally pumped via the pipes that are buried under the ground and are re-circulated in the household or office building. In summer, the air or the anti-freeze liquid in the pipes of the ground source pumps get heat from the building and takes it under the ground through the pipes, therefore working as air-coolers. Throughout winter, it draws the heat from below the earths surface and provides warm air or water to the building.
The ground source heat pumps uses a closed loop principle of evaporation of water or liquid refrigerant (that boils at a lower temperature in comparison with water and thus forms steam effectively), compression of the vapour formed and the subsequent condensation of the steam to water/liquid refrigerant for air cooling function.
Therefore, the bottom line is, geothermal energy is a commendable way of power use in the contemporary world. The warrants of its use in the purpose of air cooling and heating are:
1. Geothermal energy, being a renewable source, can effortlessly be used over and over again and thus lowers the risk of energy exhaustion in the future.
2. As a result of its sustainability and lesser degree of pollution (its use lowers carbon dioxide emissions in a big way), geothermal energy is regarded as ecologically practical source of energy.
3. This source of power is cost-effective and energy-efficient, making it dependable for future utilizes.
With countless distinct reasons, there’s no question of why geothermal energy is increasing in popularity.
