The fields of air-conditioning and refrigeration are interconnected
yet each has its own province. The largest application of
refrigeration is for air-conditioning. In addition refrigeration
has industrial uses like food preservation, in chemical, petroleum
plants, manufacturing and construction industries.
Automotive Air conditioning
Air-conditioning involves more than cooling. That is the reason
the term comfort air-conditioning is used. The most air-conditioned
vehicle is the automobile and millions of systems are sold
annually. Most of the automobiles today are fitted with air-conditioners
at the manufacturing stage. But many other conveyances are
air-conditioned as well including buses, ambulances, vans,
trailers, trucks, recreational vehicles, tractors, crane cabs,
aircrafts and ships. Air conditioning is a natural choice
while customizing a vehicle. The vagaries of climate and pollution
necessitate insulating the cabin from outside environs.
