You may feel cooler if you point fans to the right spots of the body, such as the torso, and personal fans worn around the neck can complement stationary fans, Miranda says. To get the most ...
Evaporation cools the incoming air, causing a downdraft of cool air that will bring down the temperature inside the building. [6] Airflow can be increased by using a solar chimney on the opposite side of the building to help in venting hot air to the outside. [7] This concept has been used for the Visitor Center of Zion National Park.
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. [7]
For example, a conventional heat pump system used to heat a building in Montana's −57 °C (−70 °F) low temperature or cool a building in the highest temperature ever recorded in the US—57 °C (134 °F) in Death Valley, California, in 1913 would require a large amount of energy due to the extreme difference between inside and outside air ...
The breezeway through the center of the house is a unique feature, with rooms of the house opening into the breezeway. The breezeway provided a cooler covered area for sitting. The combination of the breezeway and open windows in the rooms of the house created air currents which pulled cooler outside air into the living quarters efficiently in ...
[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 ...
On those mornings when you’re the first one out the door after a heavy snow and trudging through the snow to enjoy the sights or to get to your car, all you might hear (especially when the snow ...
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.
