Fan death is a misconception that people have died as a result of running an electric fan in a closed room with no open windows. While the supposed mechanics of fan death are impossible given how electric fans operate, belief in fan death persisted to the mid-2000s in South Korea, [1] [2] [3] and also to a lesser extent in Japan.
Handheld Brise fan from 1800. A handheld fan, or simply hand fan, is a broad, flat surface that is waved back-and-forth to create an airflow. Generally, purpose-made handheld fans are folding fans, which are shaped like a sector of a circle and made of a thin material (such as paper or feathers) mounted on slats which revolve around a pivot so that it can be closed when not in use.
Innovations in the latter half of the 20th century allowed more ubiquitous air conditioner use. In 1945, Robert Sherman of Lynn, Massachusetts, invented a portable, in-window air conditioner that cooled, heated, humidified, dehumidified, and filtered the air. [37] The first inverter air conditioners were released in 1980–1981. [38] [39]
The temperature of the air is generally maintained around 26.5 °C, getting warmer more and more due to the contact with various components, up to about 49 °C. When air is directed by fans in the warm closed corridor where, reaching the top of the room passes through the cooling coil and is cooled to room temperature.
Window and central air conditioning in the 1960s caused many companies to discontinue production of fans, [12] but in the mid-1970s, with an increasing awareness of the cost of electricity and the amount of energy used to heat and cool homes, turn-of-the-century styled ceiling fans became popular again as both decorative and energy-efficient.
An air conditioning system, or a standalone air conditioner, provides cooling and/or humidity control for all or part of a building. Air conditioned buildings often have sealed windows, because open windows would work against the system intended to maintain constant indoor air conditions.
