Geothermal heat pump — A geothermal heat pump system is a heating and/or an air conditioning system that uses the Earth s ability to store heat in the ground and water thermal masses. These systems operate based on the stability of underground temperatures: the ground… … Wikipedia
Direct exchange geothermal heat pump — A direct exchange (DX) geothermal heat pump system is a geothermal heat pump system in which the refrigerant circulates through copper tubing placed in the ground. The refrigerant exchanges heat directly with the soil through the walls of the… … Wikipedia
Earth-Coupled Ground Source (Geothermal) Heat Pump — A type of heat pump that uses sealed horizontal or vertical pipes, buried in the ground, as heat exchangers through which a fluid is circulated to transfer heat … Energy terms
Heat pump — A heat pump is a machine or device that moves heat from one location (the source ) to another location (the sink or heat sink ), using work. Most heat pump technology moves heat from a low temperature heat source to a higher temperature heat sink … Wikipedia
Heat pump efficiency — The efficiency of a heat pump, that is, the electrical energy to operate it, is directly related to temperatures between which it operates. Geothermal heat pumps are more efficient than conventional heat pumps or air conditioners that use the… … Energy terms
Heat pump and refrigeration cycle — Thermodynamic heat pump and refrigeration cycles are the models for heat pumps and refrigerators. The difference between a heat pump and a normal air conditioner is that a heat pump can be used to heat a home as well as cool it. Even though the… … Wikipedia
Heat pump — 1) (air source) An air source heat pump is the most common type of heat pump. The heat pump absorbs heat from the outside air and transfers the heat to the space to be heated in the heating mode. In the cooling mode the heat pump absorbs heat … Energy terms
Water Source Heat Pump — A type of (geothermal) heat pump that uses well (ground) or surface water as a heat source. Water has a more stable seasonal temperature than air thus making for a more efficient heat source … Energy terms
Water source heat pump — A type of (geothermal) heat pump that uses well (ground) or surface water as a heat source. Water has a more stable seasonal temperature than air thus making for a more efficient heat source. U.S. Dept. of Energy, Energy Information… … Energy terms
Geothermal power — (from the Greek roots geo , meaning earth, and therme , meaning heat) is energy generated by heat stored in the earth, or the collection of absorbed heat derived from underground, in the atmosphere and oceans. Prince Piero Ginori Conti tested the … Wikipedia
