  2. Evaporative cooler - Wikipedia

    en.wikipedia.org/wiki/Evaporative_cooler

    The system has very high efficiency but, like other evaporative cooling systems, is constrained by the ambient humidity levels, which has limited its adoption for residential use. It may be used as supplementary cooling during times of extreme heat without placing significant additional burden on electrical infrastructure.

  3. Cooling tower - Wikipedia

    en.wikipedia.org/wiki/Cooling_tower

    A typical evaporative, forced draft open-loop cooling tower rejecting heat from the condenser water loop of an industrial chiller unit Natural draft wet cooling hyperboloid towers at Didcot Power Station (UK) Forced draft wet cooling towers (height: 34 meters) and natural draft wet cooling tower (height: 122 meters) in Westphalia, Germany Natural draft wet cooling tower in Dresden (Germany)

  4. Passive cooling - Wikipedia

    en.wikipedia.org/wiki/Passive_cooling

    Passive cooling covers all natural processes and techniques of heat dissipation and modulation without the use of energy. [1] Some authors consider that minor and simple mechanical systems (e.g. pumps and economizers) can be integrated in passive cooling techniques, as long they are used to enhance the effectiveness of the natural cooling process.

  5. Windcatcher - Wikipedia

    en.wikipedia.org/wiki/Windcatcher

    The evaporative cooling within a windtower causes the air in the tower to sink, driving circulation. This is called passive downdraught evaporative cooling (PDEC). It may also be generated using spray nozzles (which have a tendency to get blocked if the water is hard) or cold-water cooling coils (like hydronic underfloor heating in reverse). [5]

  6. Passive daytime radiative cooling - Wikipedia

    en.wikipedia.org/wiki/Passive_daytime_radiative...

    When included in a combined thermal insulation, evaporative cooling, and radiative cooling system consisting of "a solar reflector, a water-rich and IR-emitting evaporative layer, and a vapor-permeable, IR-transparent, and solar-reflecting insulation layer," 300% higher [clarification needed] ambient cooling power was demonstrated.

  7. Cut Cooling Costs With the Right Roof Color -- Savings Experiment

    The wrong color on your home's exterior can cost you, so if it's time for a new coat of paint or a new roof, keep these tips in mind. A dark colored roof absorbs quite a bit of solar energy, and ...
