Geothermal System Of Heating and Cooling is Well known in Europe..

Geothermal heating and cooling

The geothermal system of heating and cooling is well known in Europe, the United States and Canada. The system is a healthy and has successfully proven technology. The core advantage Geo Energy with the use of a conventional heat pump is the temperature difference between ground and atmosphere. The land has a high thermal inertia, maintaining a virtually constant temperature throughout the year from about two feet deep - roughly 15 º C in Canada. Temperature control by Geo Energy is via a manifold installed underground, which harnesses in winter the highest temperature for heating subsurface. In summer, the system works in reverse, taking advantage of lower soil temperature for cooling. 

The system consists of three circuits: the internal circuit of the building and the underground collector, located at both ends, among them, has a refrigeration circuit that transmits pump geothermal heat or cold between the first two. To generate heat, heat from underground manifold acts on the refrigerant in the intermediate circuit, and turns it into gas. When compressed, the gas temperature increases, which is transmitted to the heat distribution circuit of the building. To generate air conditioning process is reversed, making direct use of the cold side of the refrigeration cycle. In any case, it would be wrong to understand the system simply as heating / cooling heat pump or compressor. The essence of the system is the design of the combination of a heat pump, or compressor, (with instrumentation specifically designed for use in geothermal systems) and outer manifold system designed and dimensioned specifically for each installation.

Geothermal Heat Pump

The parties are typical of a geothermal heat pump includes a compressor, heat exchanger, air trainer and condensation remover use air conditioning. All these components are generally packaged in a single cabinet. "The size of the system depends on the heating and cooling needs of your home". Geothermal heat pumps can provide hot water while the pump is stable in air.

Geothermal Loop

There are two basic line types - open and closed. The most popular type used for decades has been the open. But the lines closed, and its variants, have become increasingly popular. The lines have become the backbone of the systems of geothermal heat pumps. These work by pumping water from a well, which is located at a depth of 100-400 meters line with a heat exchanger, which can either absorb or dissipate heat, depending on the desired function. After the underground heat has been used is pumped back. It is similar with closed loops, but in them the water is constantly recycled.

Distribution

The distribution of heated or cooled air is the same as in the conventional air conditioning units or heat available in most modern buildings. The difference comes from the possible need for a system to reinforce traditional heating systems and engine driven refrigeration. The efficiency of solar systems is entirely dependent on the climate and weather at a given time, while geothermal energy is more reliable throughout the year, almost independent of the outside temperature.
