Auto ACIn 1939, the first air-conditioned automobile was exhibited by its manufacturer, Packard Motor Co. of Detroit Michigan. The public exhibition at the 40th Automobile Show in Chicago, Illinois ran between 4-12 Nov. Air in the car was cooled, dehumidified, filtered and circulated. Heat was provided for use in the winter. The refrigerating coils were located behind the rear seat in an air duct, with heating coils in another compartment of the same duct. The capacity of the unit was equivalent to 1.5 tons of ice in 24 hours when the car was driven at 60 mph. Cadillac followed in 1941. The huge evaporator left little room for luggage in the trunk, and the only way to shut it off was to stop, raise the hood, and remove the compressor belt. Cadillac followed in 1941. |
