Windcatchers that cool by drawing air over water use the water as a heat reservoir, but if the air is dry, they are also cooling the air with evaporative cooling. [2] The heat in the air goes into evaporating some of the water, and will not be released until the water re-condenses. This is a very effective way of cooling dry air. [2] Simply ...
Several man-made devices such as antique stone piles in Ukraine, medieval dew ponds in southern England and volcanic stone covers on the fields of Lanzarote have all been thought to be possible dew-catching devices. One of the first recorded projects of fog collection was in 1969 in South Africa as a water source for an air force base.
The condenser is the hot side of an air conditioner or heat pump. Condensers are heat exchangers, and can transfer heat to air or to an intermediate fluid (such as water or an aqueous solution of ethylene glycol) to carry heat to a distant sink, such as ground (earth sink), a body of water, or air (as with cooling towers). constant air volume

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 ...
Wind driven ventilation depends on wind behavior, on the interactions with the building envelope and on openings or other air exchange devices such as inlets or windcatchers. The knowledge of the urban climatology i.e. the wind around the buildings is crucial when evaluating the air quality and thermal comfort inside buildings as air and heat ...
BOB THE CAP CATCHER," the NBC Olympics & Paralympics X account posted Sunday. "He’s an icon he’s a legend he is the moment," one X user wrote , to which the NBC Olympics account responded ...
State-of-the-art AWG for home use. An atmospheric water generator (AWG), is a device that extracts water from humid ambient air, producing potable water. Water vapor in the air can be extracted either by condensation - cooling the air below its dew point, exposing the air to desiccants, using membranes that only pass water vapor, collecting fog, [1] or pressurizing the air.
