The Advantages of Geothermal Power for Air Cooling
September 4th, 2010Geothermal power is defined as the heat made in the earths core since the planets origin. This energy stems from radioactive decay of several minerals underneath the earths crust and additionally from the solar power soaked up by the earth’s surface. The energy at present, is utilized in industries, commercial companies and even in households for several capabilities and is considered ecologically feasible as it uses minimum 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.
Recently, geothermal energy gains ground as it is being increasingly more used in heating and cooling of houses and offices. This process utilizes constant temperature of the earth to heat and cool residences and companies with 40-70% less energy than standard systems. While regular heating and cooling products burn fuel or consume electricity, the geothermal power uses a much lesser amount of electricity only to pump out heat from the earth and then directly utilize the heat power for air heating or cooling.
Geothermal businesses offer ground source heat pumps, for air cooling and heating purposes, which takes heat from ground or groundwater, thus 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 method which is very much in vogue in the developed countries and is reaching a certain level of use in developing nations too. The continual heat of the earth, at about 10 feet underneath the earths surface area, continues to be around 50F, that is used by these pumps for the function. Air or anti-freeze liquids are generally pumped through the pipes which 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 extract heat from the building and takes it under the ground through the pipes, thus working as air-coolers. During winter, it draws the heat from below the earths surface area and supplies warm air or water to the building.
The ground source heat pumps utilizes a closed loop principle of evaporation of water or liquid refrigerant (that boils at a lower temperature in comparison with water and therefore forms steam effectively), compression of the vapour formed and the following condensation of the steam to water/liquid refrigerant for air cooling purpose.
Therefore, to put it succinctly, geothermal power is a noble way of power utilisation in the modern day world. The merits of its use in the purpose of air cooling and heating are:
1. Geothermal power, being a renewable source, can effortlessly be utilized over and over again and thus minimizes the risk of energy exhaustion in the long term.
2. Because of its sustainability and lesser degree of pollution (its use reduces carbon dioxide emissions in a large way), geothermal energy is thought to be ecologically feasible source of power.
3. This source of power is cost-effective and energy-efficient, making it reliable for future uses.
With a lot of distinct reasons, there’s no question of why geothermal energy is growing in popularity.
