A machine that cools your room by making the outside world hotter.
means A machine that cools indoor air by pulling heat and moisture out of it and dumping that heat outside.
from From 'air' plus 'condition,' meaning to bring something into a desired state — the verb 'condition' traces to Latin 'condicionem/condicio,' a stipulated state or terms. The compound term 'air conditioning' was coined in the early 1900s by an engineer working on controlling humidity in a textile mill, where too much moisture in the air was ruining the fabric; cooling came along as a welcome side effect, and eventually took over as the main point.
