Lpg refrigerator how does it work

The XCD is the only 3-way chest fridge we sell, as it is only small at litres in volume. Most of our customers use it for long stints in the one place — like setting up camp for a couple of weeks at a time or for a more permanent off-grid situation.

A stable, level surface is required to operate an absorption fridge in the most effective way. So a moving car, caravan, motorhome or boat is not an ideal situation. A compressor fridge uses electricity to run a low-power compressor, which in turn pumps the refrigerant through the cooling system. In general terms, a compressor fridge will also perform better in extremely hot and humid conditions. This combination makes compressor fridges the first choice for mobile use or off-grid situations where 12 V power is readily available.

A stable DC power supply is generally provided by a car battery or bank of batteries. The heat comes from burning gas, propane or kerosene. As the mixture reaches the boiling point of ammonia, it flows into the separator. Ammonia gas flows upward into the condenser, dissipates heat and converts back to a liquid.

The liquid ammonia makes its way to the evaporator where it mixes with hydrogen gas and evaporates, producing cold temperatures inside the refrigerator's cold box. The ammonia and hydrogen gases flow to the absorber where the water collected in the separator in step No. The ammonia forms a solution with the water and releases the hydrogen gas, which flows back to the evaporator. The ammonia-and-water solution flows toward the generator to repeat the cycle. The ammonia gas rises to another chamber, the condenser, where it cools back into a liquid.

It then flows to the evaporator, where it mixes with hydrogen gas. When ammonia encounters hydrogen gas, the chemical reaction between the two absorbs heat.

That's how the propane fridge produces its cooling action -- by pulling heat from the interior of the refrigerator into the ammonia-hydrogen mix. Refrigerators found in your home use a compressor to keep the air cool. Many times, RV refrigerators are called an absorption refrigerator. Those heated gases and liquids travel through tubes and inside the refrigerator casing and create evaporation, basically pulling the heat away from the inside of the refrigerator.

Your RV refrigerator will most likely work on a combination of the above. Most popular RV fridge? For this refrigerator, you must have a propane tank installed in your RV and keep it filled when it runs low on propane. This is a good refrigerator to have and requires very little thought from the RV owner.

However, there are a few cons you need to remember when purchasing a dual refrigerator:. Because this type uses propane, it can be prone to leaks in the pipes leading from the propane tank to the refrigerator.

These pipes can be hidden and difficult to navigate if you suspect a leak.
