Alternative Energy Sources

Today, much attention is paid to alternative energy sources. One of the most popular today are wind turbines and solar panels. They are increasingly used in industrial environments and in privately. Since solar panels and wind turbines, experts suggest using in country houses. Another type of alternative energy is to use the energy of the Earth (as well as air, water, etc.). Realize it is possible by means of heat pumps included in the energy system of about one hundred fifty years ago the British physicist William Thomson invented a device called the "multiplier heat", based on his lay following physical phenomena: material expends energy during evaporation and condensation releases energy: boiling point of a substance varies with pressure. The result was the birth of a heat pump, ie device to transfer heat energy from a source with lower temperature to a source with a higher temperature. In other words – a refrigerator with a source of lower temperature in the environment or air-conditioning, working on heating. The principle of heat pump based on the fact that the refrigerant evaporates in the chamber with low pressure and temperature and is condensed in a chamber with high pressure and temperature, thus carrying out transfer of energy (heat) from a cold body to a heated, ie in the direction in which the spontaneous heat transfer is impossible. As a low-potential source of thermal energy for heating a house can be used naturally occurring heat (ambient air, heat groundwater, artesian and thermal waters, the waters of rivers.
