ECCs (evaporative cooling chambers) and clay pot coolers provide the most benefits when they are used in low humidity climates (less than 40% relative humidity), the temperature is relatively high (maximum daily temperature higher than 25 °C), water is available to add to the device between one and three times per day, and the device can be ...
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.

Unlike other types of air conditioners, evaporative coolers rely on the outside air to be channeled through cooler pads that cool the air before it reaches the inside of a house through its air duct system; this cooled outside air must be allowed to push the warmer air within the house out through an exhaust opening such as an open door or window.
OutsideXbox, or Oxbox, is a British YouTube channel and group consisting of Jane Douglas, Andy Farrant and Mike Channell. The group also has a sister channel, Outside Xtra, or Oxtra, consisting of Ellen Rose. The group is best known for video games commentary, journalism, and gameplay.
The outside air comes in contact with water inside the tower either through a wetted membrane or a mister. As water evaporates in the outside air, the air becomes cooler and less buoyant and creates a downward flow in the tower. At the bottom of the tower, an outlet allows the cooler air into the interior.
The closed loop system can be more effective cooling the air (during air temperature extremes) than an open system, since it cools and recools the same air. Open system: Outside air is drawn from a filtered air intake (Minimum Efficiency Reporting Value MERV 8+ air filter is recommended) to cool or preheat the air. The tubes are typically 30 m ...
They are made by the combination of two types of clay: the first is taken from the surface of the earth and the second after digging more than 10 feet deeper into the earth. Making a matka is a long process of at least 8 days. The clay is mixed with water, shaped, finished, polished, dried and fired in a kiln for 5 days.
[10] [11] The equations apply only to buildings where air is both inside and outside the buildings. For buildings with one or two floors, h is the height of the building. For multi-floor, high-rise buildings, h is the distance from the openings at the neutral pressure level (NPL) of the building to either the topmost openings or the lowest ...
