Unlike what many people think,
an air conditioner does not ADD cool air
to an area but instead REMOVES heat from
the existing air, leaving the remaining
Oversimplified, the miracle of cooling
is accomplished by the user of (1) refrigerant;
(2) a compressor and (3) an evaporator.
Refrigerant acts like a sponge."Squeeze"
(compress) it and the heat is expelled;
let it expand and it will absorb heat.
If you squeeze it outside, the heat is expelled
into the air; bring it back into the house
and let it expand and it will soak up more
heat from within.
