Question:
How do those mini Fridges work, without any refrigerant gas/liquid?

You know those tiny mini fridge freezers with 12v power, just big enough to take a can of coke, how do they chill when they have no refrigerant gas/liquid?

Answer:
They have thermoelectric fitting, these devices that use the Peltier-Seebeck effect to cool the mini fridge. This works by running a direct current  through them, this cause one side to get hot and the other side gets cold. The cool side is facing the interior of the fridge making it the inside of the fridge cold
