The Benefits of Geothermal Energy for Air Cooling
Geothermal power is defined as the heat generated in the earths core since the planets source. This power stems from radioactive decay of a number of minerals below the earths crust and also from the solar power consumed by the earth’s surface area. The energy at present, is used in industries, commercial businesses and even in households for various functions and is thought to be ecologically feasible as it uses minimal exhaustible resources of the earth. The thermal efficiency of this power is additionally high as little or no energy conversion is required during its use.
In recent years, geothermal energy gains ground as it is being more and more used in heating and cooling of homes and offices. This process makes use of constant temperature of the earth to heat and cool houses and organizations with 40-70% less power than traditional systems. While normal heating and cooling units burn fuel or consume electricity, the geothermal energy utilizes a much lesser amount of electricity only to pump out heat from the earth and then directly use the heat power for air heating or cooling.
Geothermal companies provide ground source heat pumps, for air cooling and heating functions, that takes heat from ground or groundwater, thus lowering carbon dioxide emissions and electricity bills and improving 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 achieving a certain level of use in developing nations too. The regular heat of the earth, at about 10 feet under the earths surface, stays around 50F, which is used by these pumps for the purpose. Air or anti-freeze liquids are typically pumped via the pipes which are buried under the ground and are re-circulated in the household or office. In summer, the air or the anti-freeze liquid in the pipes of the ground source pumps draw out heat from the building and takes it under the ground through the pipes, therefore working as air-coolers. During winter, it pulls the heat from under the earths surface area and supplies 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 when compared 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, in a nutshell, geothermal power is a respectable way of power use in the modern-day world. The merits of its use in the purpose of air cooling and heating are:
1. Geothermal energy, being a renewable source, can easily be used over and over again and therefore reduces 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 power is considered to be ecologically viable source of energy.
3. This source of energy is cost-effective and energy-efficient, making it trustworthy for future makes use of.
With so many distinct reasons, there’s no question of why geothermal power is growing in popularity.
