Back in the day, R-12 was the rock star of the cooling world. It lived inside your car’s air conditioner, your fridge, and even your hairspray. Why? Because it was cheap, stable, and didn’t catch fire like the old refrigerants, which would turn your kitchen into a mini fireworks show.
Imagine driving a 1972 Buick with a sweaty back and a R-12-fed A/C that could freeze a penguin’s toes. That was luxury. People loved it so much they sprayed it everywhere—out of cans, out of cars, out of fridges—without a single thought for the poor ozone layer.
But Then It Got a Criminal Record
Here’s the kicker: R-12 is so stable that it doesn’t break down in the lower atmosphere. It just floats up, up, and away, like a lazy balloon, until it reaches the stratosphere. Then, the sun’s UV rays hit it, and BAM—it releases chlorine atoms that start a dance party that destroys ozone molecules.
One single chlorine atom from your old fridge can destroy 100,000 ozone molecules before it gets tired. That’s like one drunk uncle at a wedding ruining an entire buffet for 100,000 guests. Suddenly, that cold beer in your hand doesn’t seem so innocent, does it?
