  2. Ground source heat pump - Wikipedia

    en.wikipedia.org/wiki/Ground_source_heat_pump

    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.

  3. Geothermal heating - Wikipedia

    en.wikipedia.org/wiki/Geothermal_heating

    Geothermal heating is the direct use of geothermal energy for some heating applications. Humans have taken advantage of geothermal heat this way since the Paleolithic era. Approximately seventy countries made direct use of a total of 270 PJ of geothermal heating in 2004. As of 2007, 28 GW of geothermal heating capacity is installed around the ...

    en.wikipedia.org/wiki/Direct_exchange_geothermal...

    Direct exchange heat pumps are closed-loop geothermal systems which rely on (¼” to 1-1/8”) copper pipes to exchange heat with the earth. The copper pipes are placed in the ground and form a ground loop – sometimes also referred to as earth loop or refrigerant loop – where the circulating refrigerant undergoes phase transition by ...

  7. Heat pump - Wikipedia

    en.wikipedia.org/wiki/Heat_pump

    e. A heat pump is a device that consumes energy (usually electricity) to transfer heat from a cold heat sink to a hot heat sink. Specifically, the heat pump transfers thermal energy using a refrigeration cycle, cooling the cool space and warming the warm space. [1] In cold weather, a heat pump can move heat from the cool outdoors to warm a ...
