How Does a Gas Powered Refrigerator Work?
Gas Refrigerator Basics Gas powered refrigerators are usually called absorption refrigerators because they work by alternately absorbing and evaporating ammonia gas. They are less efficient than regular refrigerators, because they require a burner, which produces a lot of waste heat. For this reason, they aren’t normally used in buildings or cars. They are commonly used in campers and RVs because they don’t need an electrical outlet, and can be run off of a propane burner. They are also almost completely silent. Generator and Condensor The generator contains a mixture of water and ammonia. A burner heats the mixture. Ammonia evaporates at a lower temperature than water, so the generator is kept at just the right temperature to bubble the ammonia without making the water boil. The ammonia gas drifts up into the condenser, where it cools down and condenses into liquid ammonia, separated from the water. Evaporator The ammonia then flows down into a chamber called the condenser. The conden
