  2. Ground-coupled heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Ground-coupled_heat_exchanger

    Ground-coupled heat exchanger. A qanat and windcatcher used as an earth duct, for both earth coupling and evaporative cooling. No fan is needed; the suction in the lee of the windtower draws the air up and out. A ground-coupled heat exchanger is an underground heat exchanger that can capture heat from and/or dissipate heat to the ground.

  3. Seawater greenhouse - Wikipedia

    en.wikipedia.org/wiki/Seawater_Greenhouse

    The greenhouse is assisted by the prevailing wind, evaporative cooling, transpiration, solar heating, heat transfer through the walls and roof, and condensation which is analyzed in the study. [18] They found that the amount of water required by the plants is reduced by 80% and 2.6-6.4 kWh electrical energy is needed for m3 of fresh water produced.

  4. Evaporative cooler - Wikipedia

    en.wikipedia.org/wiki/Evaporative_cooler

    An evaporative cooler (also known as evaporative air conditioner, swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from other air conditioning systems, which use vapor-compression or absorption refrigeration cycles.

  5. Ground source heat pump - Wikipedia

    en.wikipedia.org/wiki/Ground_source_heat_pump

    A heat pump is the central unit for the building's heating and cooling. It usually comes in two main variants: Liquid-to-water heat pumps (also called water-to-water) are hydronic systems that carry heating or cooling through the building through pipes to conventional radiators, underfloor heating, baseboard radiators and hot water tanks. These ...

  6. Pumpable ice technology - Wikipedia

    en.wikipedia.org/wiki/Pumpable_ice_technology

    The maximum value of cooling energy of pumpable ice accumulated in the storage tank in a homogeneous phase is about 700 kWh, which corresponds to 10–15 m 3 volume of a storage tank. A high-shear mixer is used to prevent the separation of ice from the cooled liquid and keeps the ice concentration unchanged over time and unaffected by the tank ...

  7. Ice storage air conditioning - Wikipedia

    en.wikipedia.org/wiki/Ice_storage_air_conditioning

    Ice storage air conditioning is the process of using ice for thermal energy storage. The process can reduce energy used for cooling during times of peak electrical demand. [1] Alternative power sources such as solar can also use the technology to store energy for later use. [1] This is practical because of water's large heat of fusion: one ...
