A propane flame heats the water and ammonia to its boiling point in what is called the generator. The now-gaseous material then rises into a condensing chamber where it cools and returns to a liquid state. It’s here that a chemical reaction occurs that pulls, or absorbs, heat from inside the refrigerator.
Does a gas refrigerator need electricity?
A fuel gas refrigerator does not require electrical power at all. That said, most have the option to use electric power. RVs are the most common users of propane refrigerators and while staying in a park most owners opt to use the available electric plug and save propane.
Are gas refrigerators efficient?
Unfortunately, gas refrigerators are not efficient. They usually use a large amount of energy to power their cooling process and sometimes don’t perform well under hot temperatures. If you can avoid using them in warm weather, it’s best to do so because they require more electricity to work than other types of fridges.
Does a gas fridge have a compressor?
The simple answer to this is that yes, your fridge compressor comes with gas. By gas, we refer to the liquid refrigerant that is considered the fuel of your refrigerator.

How does a propane refridgerator work?
A propane fridge has a sealed network of tubes and chambers holding water, ammonia and hydrogen gas. A propane flame heats a chamber holding a solution of water and ammonia until the liquid boils. The ammonia gas rises to another chamber, the condenser, where it cools back into a liquid.
How much gas does a gas fridge use?
A smaller more common unit will use 187 to 257 grams per 24 hours at 25 deg C . The higher use rate assumes you set the fridge to maximum cooling. So let’s assume 200 g per 24 hrs you new 4.5 kilo cylinder should last 22.5 days.

Can a fridge compressor explode?
Sometimes, the rear of the fridge can get extremely hot, as the gas that cools down the fridge returns through the compressor and becomes trapped inside. That trapped gas, stuck within the fridge’s compressor, leads to a pressure build up silently—and, eventually, an explosion.
Do propane refrigerators need to be vented?
The back of the refrigerator has two air vents that are exposed to the outside. Unlike electric refrigerators, propane units for RVs and mobile homes require ventilation to the outside. Not to mention, burning propane produces carbon monoxide, which needs to be vented outside of the cabin.
