First the heat
Electric refrigerators use a coolant to keep the interior cold. In contrast, a propane fridge relies on simple chemical reactions. The process of propane refrigeration begins with a flame fed by a propane tank, which is why the appliance is called a propane fridge.
Every propane fridge contains a sealed network of tubes and chambers which hold water, ammonia and hydrogen gas. When a propane flame heats a chamber holding a solution of water and ammonia, the liquid begins to boil. Then the ammonia gas rises to another chamber, the condenser. In the condenser, the ammonia cools back into a liquid. This liquid then flows to the evaporator, where it mixes with hydrogen gas.
Then the cooling
When ammonia meets the hydrogen gas, the chemical reaction between the two absorbs heat. In that way, the propane fridge produces its cooling action. Heat is pulled from the interior of the refrigerator into the ammonia-hydrogen mix. As heat is absorbed, the ammonia becomes a gas once again. The ammonia and hydrogen gases then combine with water. The ammonia and water form a solution yet again. That process releases the hydrogen gas to rise back to the evaporator. The process then starts all over again and is repeated continuously – all with no moving parts!
Among the many benefits of propane refrigerators, the fact that it has no moving parts means quiet operation and no mechanical issues. We proudly carry EZ Freeze gas refrigerators.
