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.
