Fans can help keep your home comfortable
year round. If the summer air temperature
remains on the mild side of warm and the
humidity remains at comfortable levels --
or if your hot season is brief -- consider
using fans in place of air conditioning to cool your home. In hot climates, fans
can be an economical enhancement to an air
conditioning system that can reduce the cooling
power and running time. In winter, fans can
supplement your heating system.
Fans help in two ways: they can redistribute
air and they can blow air directly on you.
When left on its own, air stratifies, with
warm air accumulating near the ceiling and
cooler air accumulating near the floor. In
the winter, a fan can be used to gently move
the warm air back towards the lower portions
of the room and thus raise the apparent temperature
of the room. In summer, fans that cause air
to pass over our skin increases evaporation,
and thus enhances the body's normal cooling
and our comfort.
