How It Works:
• Ram-air design: As the vehicle moves, forward momentum forces outside air through the unit's intake.
• Evaporation: Air passes through an internal water-soaked pad or wood shavings, dropping the temperature through natural evaporation.
• Cabin airflow: The cooled, humid air is funneled directly into the car window, requiring another window to be cracked slightly for exhaust flow.
Info by AI.
Way back in the day before my time, my grandfather, like many other motorists in the 1940’s and 1950s, would keep a damp towel, a gallon jug of water and a spray bottle handy when driving across the deserts of California and the SouthWest. You place the damp towel on your chest and use the spray bottle to keep the towel damp and yourself cool. The poor man’s air conditioning, as air conditioning was a rare option on cars of that time. Packard offered AC first in 1940, a very expensive option, it was a split system with components under the hood and in the trunk. The AC had no on/off switch, you had to pop the hood and disconnect the AC belt ! A more practical and affordable AC, with all its components under the hood and an on/off switch, was offered by Nash in 1954.
