Central air conditioning,
like any refrigeration system, works by moving heat energy from
one location to another. A split-system air conditioner includes
an evaporator coil located inside a home, usually within
ductwork otherwise used for forced-air heating. Air is
moved through the ductwork and across the air conditioning
coil by the furnace blower. Heat energy contained in this air
flow is absorbed by a refrigerant, usually R-22 in residential systems,
that circulates quietly within the evaporator/condenser loop.
The now-heated, gaseous refrigerant is transported through tubing
to the outdoor component of the split-system where it enters
the condenser coil. A fan in the outdoor unit blows outside
air across this coil, thereby reducing the temperature of the
refrigerant which then enters a compressor for conversion to
its liquid form. The cooled refrigerant re-enters the home on
its way to the evaporator coil where a pressure let-down valve
allows it to vaporize in order to efficiently collect another
load of heat energy. This quiet, efficient design uses some existing equipment, the furnace blower and forced-air ductwork, in addition to highly reliable air conditioning components to provide whole-house comfort on those sweltering Ontario days and muggy, sleep-depriving nights. While the split-system air conditioner is the most common for whole-house cooling, other options are available depending on your needs and installation circumstances.
