Ceiling Fans

It's time to write candidly about ceiling fans. After years of nodding to winter or summer directions of rotation, I end my silence. A fan will not cool a space. In fact, the fan adds heat. The energy it uses is not destoyed, and is dissapated into the space as heat from mechanical friction and motor losses. The actual air movement is kinetic energy, faster molecules, heat energy. Sound crazy? Refrigeration calculations include evaporator fan heat load. These are small numbers.

The fan "cools" by providing air movement which aids evaporating cooling of sweat on the skin. It "heats" by agitating the air in a room to prevent stratification, moving warm air from the ceiling to create a uniform air temperature.

Soooooo which direction should it turn? I say what's the difference. It will ciculate air to a uniform temperature, regardless of direction. But I will still nod to whatever direction you say.
