When did albert Einstein invent the refrigerator and how?

Answer 1

Yes, Einstein did invent a refrigerator. He only designed one. He did not invent the FIRST one.

Einstein did however invent the FIRST refrigerator having no moving parts and thus requiring no seals, which might develop leaks. This was very important at the time, as all available refrigerants were either toxic or flammable and refrigerator leaks were killing people!

However his invention became irrelevant just a few years later when the safe freon refrigerants were invented. The only place where it ultimately saw use was in the liquid metal cooling systems of certain types of nuclear reactors, where the sodium and potassium metal coolants used react violently on contact with either water or air.

Answer 2

Albert Einstein did not invent the refrigerator. The first refrigerator was invented in 1834 by Jacob Perkins, and over the years, various improvements and innovations have been made by different inventors in the field of refrigeration technology.
