A gas refrigerator does not require electricity so it is perfect for camping and other off-grid uses. The refrigerant is water, ammonia and hydrogen gas. The refrigerant moves through a coil of tubes. The LPG heats a container holding the refrigerant until it boils. The ammonia gas then rises to the condenser, where it cools and condenses back into a liquid. This is a continuous process when the fridge is running.
