  2. Heat pump - Wikipedia

    en.wikipedia.org/wiki/Heat_pump

    A heat pump is a device that uses work to transfer heat from a cool space to a warm space by transferring 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 house; the pump may also be designed to move heat from the house ...

  3. Heat pump and refrigeration cycle - Wikipedia

    en.wikipedia.org/wiki/Heat_pump_and...

    Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [1]

  4. Absorption heat pump - Wikipedia

    en.wikipedia.org/wiki/Absorption_heat_pump

    An absorption heat pump ( AHP) is a heat pump driven by thermal energy such as combustion of natural gas, steam solar-heated water, air or geothermal-heated water [1] [2] differently from compression heat pumps that are driven by mechanical energy. [citation needed] AHPs are more complex and require larger units compared to compression heat ...

    A heat pump provides cool air in the summer and heat in winter. In cooling mode, a heat pump works like a refrigerator, using a refrigerant to cool hot air pulled from outdoors. To provide heat ...

  6. Are heat pumps the key to accelerating the energy transition?

    www.aol.com/news/heat-pumps-key-accelerating...

    Heat pumps consume a lot less energy and are at least three times more energy efficient compared to conventional heating and air conditioning systems. Heat pumps cost a bit more upfront but do ...

  7. Thermodynamic cycle - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_cycle

    Thermodynamic heat pump cycles are the models for household heat pumps and refrigerators. There is no difference between the two except the purpose of the refrigerator is to cool a very small space while the household heat pump is intended to warm or cool a house. Both work by moving heat from a cold space to a warm space.
