A heat pump in combination with heat and cold storage. A ground source heat pump (also geothermal heat pump) is a heating/cooling system for buildings that use a type of heat pump to transfer heat to or from the ground, taking advantage of the relative constancy of temperatures of the earth through the seasons.
Duration of treatment with atorvastatin is unlikely to increase the risk of muscle-related side effects as most occur within the first year of treatment, after which the risk is not increased further. [64] The known cardiovascular benefits of atorvastatin over time outweigh the low risk of muscle-related side effects. [65] [64]
A ground-source heat pump uses the shallow ground or ground water (typically starting at 10–12 °C or 50–54 °F) as a source of heat, thus taking advantage of its seasonally moderate temperatures. [15] In contrast, an air source heat pump draws heat from the air (colder outside air) and thus requires more energy.
DX system being drilled in the 1980s. A direct exchange (DX) geothermal heat pump is a type of ground source heat pump in which refrigerant circulates through copper tubing placed in the ground unlike other ground source heat pumps where refrigerant is restricted to the heat pump itself with a secondary loop in the ground filled with a mixture of water and anti-freeze.
ATES can heat and cool buildings. Storage and recovery is achieved by extraction and injection of groundwater using wells. Systems commonly operate in seasonal modes. Groundwater that is extracted in summer performs cooling by transferring heat from the building to the water by means of a heat exchanger. The heated groundwater is reinjected ...
Earth-air heat exchangers appear best suited for air pretreatment rather than for full heating or cooling. Pretreatment of air for an air source heat pump or ground-source heat pump often provides the best economic return on investment, with simple payback often achieved within one year after installation.
A water-source heat pump works in a similar manner to a ground-source heat pump, except that it takes heat from a body of water rather than the ground. The body of water does, however, need to be large enough to be able to withstand the cooling effect of the unit without freezing or creating an adverse effect for wildlife. [ 30 ]
Application: Ground source heat pumps are most often used for small-scale residential and commercial buildings, and are only used for heating and cooling applications. [19] Closed-loop geothermal systems are most suitable for large-scale commercial and industrial use, and can be used for electricity production, in addition to 'direct use ...
