geothermal heat pump

Geothermal Energy - Ever since the earth was formed, huge amount of heat energy has been stored in its molten core. Some of this heat is always flowing towards the surface. This heat is called Geothermal Energy. The hot interior of the earth he..

Geothermal energy can be used to generate electricity in various ways. If dry steam comes out of the surface of the earth, it can be used directly to turn turbines connected to generators. The world's largest geothermal electric power plant, at Geysers Steam Field, Californi..

Refrigerator or Heat Pump - A heat engine takes heat from a hot body, converts a part of it into work and rejects the rest to a cold body. A refrigerator also known as a heat pump, does the reverse operation. It takes an amount of hea..

Energy obtained by tapping underground reservoirs of heat, usually near volcanoes or other hot spots on the surface of the Earth is known as geothermal energ..

Geothermal Energy - 'Geo' means earth and 'thermal' means heat. Thus geothermal energy is that heat energy obtained from hot rocks present inside the earth. This heat can be used as a source of energy to produce electricity. You know that the innerm..

The heat released during the fission reaction is carried away by liquid sodium or heavy water. The coolant enters from the base of the reactor core and leaves at the top. The heat carried away by the coolant is used for producing steam and the coolant is pumped back i..

When a neutron hits the enriched U-235, energy is released and this heat generated in the reactor is carried away by heavy water or liquid sodium. This energy is used for generating steam in the heat exchanger. The steam thus produced is used by the turbines and these are in tu..

Solar energy is responsible for the blowing of wind. The intensity of sun-rays is stronger near the Equator than at the Polar Regions. Due to unequal heating of the earth's surface, cooler air from the Polar Regions flow towards the equatorial regions to fill the space created by the ho..

. Generalizing this observation, we state: It is impossible for any process to sole result in the transfer of heat from a cooler to a hotter body. We call this the 'refrigerator' statement of the second law. Though, it may not seem to be very closely related to the 'engine' statement, the..
