As
mercury levels rise, air conditioners
come as a blessing: they help you beat the heat. With so much advertising from
various AC manufacturers on features, consumers today are a confused lot. Let
us understand some of the basic features of an AC so that you are able to buy
an energy efficient AC.
Air-conditioning or cooling is more complicated than heating.
Instead of using energy to create heat, ACs use energy to take heat away. The
most common air-conditioning system uses a compressor cycle (similar to the one
used by your refrigerator) to transfer heat from your house to the outdoors.
How is
this done? A compressor is filled with a special fluid called a refrigerant
(usually one of the environmentally notorious chlorofluorocarbons). One of this
chemical's properties is that it can change back and forth between liquid and
gas. As it changes, it absorbs or releases heat.
Thus, it is used to "carry" heat from one place to
another, such as from the inside of a refrigerator to the outside, or, in an
air conditioner, from the inside of a house to the outside. An air conditioner
takes heat from a cooler place and dumps it in a warmer place, seemingly
working against the laws of physics. What drives the process, of course, is
electricity—quite a lot of it, in fact.
Human comfort
In looking at how air-conditioning costs can be reduced, it
helps to understand how temperature affects human comfort. The standard human
comfort range for light clothing in the summer is between 72 degrees Fahrenheit
and 78 degrees Fahrenheit and between 35% and 60% relative humidity, according
to the American Society for Heating, Refrigeration, and Air- Conditioning
Engineers (ASHRAE).
The comfort range can be extended to 82 degrees F with modest
air movement, as might be provided by ceiling fans, for example. Often, the
house can be kept within this range using little or no mechanical
air-conditioning.
