How do air conditioners/refridgerators work? EK book devotes some space to explaining it but I don't understand.

A compressor puts energy into some gas by compression. The gas enters the inside of the fridge where it expands, absorbing heat. After it absorbs/expands, it reenters the compressor and it is compressed, releasing the heat that it has absorbed and its temperature rises as a result. Then it goes into that huge bunch of tubes in the back of the fridge to cool back down before reentering the inside of the fridge.

Well said.

Just don't confuse the gas entering the fridge with the gas ACTUALLY entering the fridge.

There is just heat transfer between the ice cold gas in the coils inside the fridge and the air in the fridge.
