Rapid evaporation
The ancient Egyptians found out about rapid evaporation in 500 AD where they would put water in a clay pot and leave it out over night where it would evaporate. Scientifically, when the water was evaporating so fast it was causing kinetic energy forcing it to be unstable and due to the vapor around it would freeze. -

The Ammonia fridge
Ferdinand Carré of France made a fridge different then the vapor compression ones like before, he made one the used rapid cooling ammonia.The ammonia could hold more heat then the vapor making it more effective,But it was highly toxic so they searched for a answer. -

The first modern fridge.
In 1920 they came up with a chemical called Freon Which was made up of two chlorine and flourine atoms.In which that they would force it through a pipe in a circle releasing heat as it went into the condenser and back in in the compressor. -

This fridge got upgrades like a freezer and lots of customizable colors and variants.It also was much more appealing to the eye as you can see and had a smaller cooling system. -
