Ground Source Heat Pump Installation
Ground source heat pump (GSHP) is a central heating and air conditioning that pumps heat to or from the ground. Heat pumps provide winter time heating simply by taking out heat from a source transferring it to the building. In theory, heat can be extracted from any source, no matter how cold, but a warmer source allows higher efficiency. A ground source heat pump uses the top layer of the earth crust (usually three to 500 feet deep) as a source of heat, thus taking advantage of its seasonally moderate temperatures.
During the summer time, the method may be reversed so the heat pump extracts heat from the building and transfers it to the ground. Transferring heat to a cooler space takes less energy, so the cooling efficiency of the heat pump gain benefits from the lower ground temperatures.
Geothermal heat pumps utilize electrical energy for heating and cooling just like a conventional heat pump. However, unlike a conventional heat pump, GSHPs use the relatively constant temperature of the shallow Earth as a source of heat in the winter and as a repository for heat in the summer.
The heat pump system uses solar power saved in the earths crust. Energy is transmitted to and from the earth's surface by solar radiation, wind and rainfall. As a consequence of this solar power, the earth’s heat range at depths greater than 10 measures remains continuous, and is comparable to the yearly regular air heat range. Between the surface and a level of 2.5 measures (maximum level for a horizontal loop) the world heat range will swing above and below the yearly regular air heat range, depending on the geographic location, soil type and moisture levels.
Because of its own insulation, the earth's soil temperature is more moderate year round than outside air. Ground Source Heat Pumps simply move heat from one place to another.
Ground Source Heat Pumps can be categorized as having closed or open loops, and those loops can be positioned in three techniques: horizontally, vertically, or perhaps a pond/lake. The type chosen is dependent upon the free land areas and the soil and rock type at the installation site. These elements will help decide one of the most economical selections for installing of the ground source heat pump.
A ground source heat pump involves a long plastic tube hidden below the earth's surface. This plastic tube is hidden in the ground, or ground coupled, to allow heat transfer between antifreeze solution in the tube and the earth. The heat pump transfers heat power to and from the closed, hidden tube and the building heat load. The method involves the closed-loop hidden tube, a water-sourced heat pump and a power submission method. In some cases the heat pump can provide domestic hot water (DHW).
