  2. Solar radiation modification - Wikipedia

    en.wikipedia.org/wiki/Solar_radiation_modification

    The first modeled results of and review article on SRM were published in 2000. [24] [25] In 2006, Nobel Laureate Paul Crutzen published an influential paper arguing that, given the lack of adequate greenhouse gas emissions reductions, research on the feasibility and environmental consequences of climate engineering should not be dismissed. [26]

  3. Ground-coupled heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Ground-coupled_heat_exchanger

    However, the earth can be used to partially cool and dehumidify the replacement fresh air intake for passive-solar thermal buffer zone [5] areas like the laundry room, or a solarium / greenhouse, especially those with a hot tub, swim spa, or indoor swimming pool, where warm humid air is exhausted in the summer, and a supply of cooler drier ...

  4. Heat recovery ventilation - Wikipedia

    en.wikipedia.org/wiki/Heat_recovery_ventilation

    Diagramatic operation of a thermal wheel Ljungström Air Preheater by Swedish engineer Fredrik Ljungström (1875–1964). A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, energy recovery wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of air-handling units or rooftop ...

  5. Solar air conditioning - Wikipedia

    en.wikipedia.org/wiki/Solar_air_conditioning

    A solar chimney or photovoltaic-powered fan can be used to exhaust undesired heat and draw in cooler, dehumidified air that has passed by ambient Earth temperature surfaces. Control of humidity and condensation are important design issues.

  6. Heating system - Wikipedia

    en.wikipedia.org/wiki/Heating_system

    The use of renewable energy sources like geothermal heating, solar panels, and biomass. Current trends are toward heating pumps and using renewable energy/low carbon emission energy to power these heaters. [13] Swapping out the current fossil-fuel based heaters for electric ones lowers emissions in the heating industry.

  7. Solar thermal energy - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_energy

    Solar thermal heat is trapped using the greenhouse effect; the greenhouse effect in this case is the ability of a reflective surface to transmit short wave radiation and reflect long wave radiation. Heat and infrared radiation (IR) are produced when short wave radiation light hits the absorber plate, which is then trapped inside the collector.

  8. Centrifugal fan - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_fan

    A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, or squirrel-cage fan (because it looks like a hamster wheel).

  9. Solar thermal collector - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_collector

    The term "solar collector" commonly refers to a device for solar hot water heating, but may refer to large power generating installations such as solar parabolic troughs and solar towers or non-water heating devices such as solar cookers or solar air heaters. [1] Solar thermal collectors are either non-concentrating or concentrating.
