ventilador de teto português - portuguese fan

HUMOR
====
Um ventilador ou ventoinha é um dispositivo mecânico utilizado para converter energia mecânica de rotação, aplicada em seus eixos, em aumento de pressão do ar. Foi inventado nos EUA (Estados Unidos da América) em 1882, pelo americano Schuyler S. Wheeler.
Este aparelho pode ser de distintos tipos, consoante o sentido de fluxo de ar em relação ao ambiente ventilado: sopradores (se há injeção de ar no ambiente) ou exaustores (se há retirada de ar do ambiente).
Existem basicamente dois tipos de ventiladores, cuja escolha depende basicamente da aplicação: os axiais e os centrífugos.
Os ventiladores podem encontrar-se em diversos tamanhos e formatos, podendo ser fixados no solo (através de pedestais) na parede ou no teto. Geralmente também se usam como objeto decorativo acompanhando muitas vezes lustres e luminárias.

A fan is a machine used to create flow within a fluid, typically a gas such as air.
A fan consists of a rotating arrangement of vanes or blades which act on the air. Usually it is contained within some form of housing or case. This may direct the airflow or increase safety by preventing objects from contacting the fan blades. Most fans are powered by electric motors, but other sources of power may be used, including hydraulic motors and internal combustion engines.

Fans produce air flows with high volume and low pressure, as opposed to compressors which produce high pressures at a comparatively low volume. A fan blade will often rotate when exposed to an air stream, and devices that take advantage of this, such as anemometers and wind turbines, often have designs similar to that of a fan.
Typical applications include climate control, vehicle and machinery cooling systems, personal comfort (e.g., an electric table fan), ventilation, fume extraction, winnowing (e.g., separating chaff of cereal grains), removing dust (e.g. in a vacuum cleaner), drying (usually in combination with heat) and to provide draft for a fire. It is also common to use electric fans as air fresheners, by attaching fabric softener sheets to the protective housing. This causes the fragrance to be carried into the surrounding air.
In addition to their utilitarian function, vintage or antique fans, and in particular electric fans manufactured from the late 19th century through the 1950s, have become a recognized collectible category, and in the U.S.A. an active collector club, the Antique Fan Collectors Association, supports the hobby.
New to the market are sleek portable fans that showcase a modern design sensibility. The New York Times lamented the inexpensive and effective fans abound at drug and discount stores for often being eyesores. The writer quoted contemporary ceiling fan designer Ron Rezek as saying: "Portable fans are the ugly ducklings of the fan industry. Not many designers, including myself, have tackled them."[2] Rezek praised several appealing contemporary fan designs that have found alternatives to the traditional metal cage and have incorporated innovative approaches to safety, such as the Otto fan by Swiss designer Carlo Borer.
