On average, a battery will not be capable of powering your RV fridge. It is not precise, though, because the duration is impacted by the length of your RV, refrigerator, and a few other key elements. So, once you get the specifications for your RV, you will need to compensate for those things.
Now that you understand how long propane will power an RV fridge let us explain how it works. We’ll also look at how much propane each of these fridges consumes. Then we’ll look at how you might lower the amount of gas your RV fridge uses. We will answer a couple more questions after you have all that information.
We understand that if you are unfamiliar with the world of RVs, you most likely have a lot on your mind. So we decided it would be a good idea to assist you by reviewing some of the top RV freezers on the market. You may not find the ideal refrigerator for you.

How Does an RV Fridge Work?
Before you know an RV fridge, people might imagine it operates like a domestic fridge. Your home refrigerator has a compressor. However, your RV refrigerator does not include compressed air or moving parts to keep things cool. It is, instead, an absorption refrigerator.
An absorption fridge heats a mixture of ammonia, oxygen, gas, or water using a flame to keep things simple. The heat makes chemicals evaporate, and the moisture from these evaporated chemicals cools the refrigerator. Heat is generated by an element when using mains electricity or a generator. When employing LP gas, however, it is employed to generate the flame to heat the chemicals. Modern
How Much Propane Does an RV Fridge Use?
Most newer RV refrigerators are more able to withstand high temperatures than previous models. As a result, a new RV refrigerator may cost less to operate in the long run. Size, on the other hand, raises overall energy demand. A contemporary RV fridge with an internal volume of 10 to 12 cubic feet will typically consume 1.5 pounds of propane daily. This equates to approximately 1400 BTUs each hour. That being said, some things can increase or degrade the operation of the RV fridge.
Do I require a Batteries to Run My Propane Refrigerator?
You may believe that because your refrigerator runs on gas, a battery is unnecessary. However, because all contemporary RV fridges contain a circuit board that serves as the unit’s brain, a battery was required to power the control board. The quantity of propane used by your RV fridge is determined by size and age. Older vehicles are inefficient.
Moreover, the larger the fridge, the more gas you’ll need to fuel it. The voltage required to run the fridge will vary depending on the type and model, but it will need a battery. The controller requires some power, and the ignition requires a battery. It does not have to be a powerful battery.
RV refrigerators, unlike house refrigerators, do generally not include a built-in circulation fan. Install an RV fridge fan to assist in circulating air & keep the inside cool.
Attach this fan to the evaporator fins of your RV’s fridge to assist spread cold air evenly throughout the fridge.
The Operation of a Hydrogen RV Fridge
To keep beverages and food cold, your refrigerator requires freon. However, your regular RV fridge is not like that. It operates by combining hydrogen, ammonia, plus water. They work together to provide a decisive evaporation action that removes heat & keeps things cool.
That sounds hard, but it isn’t. An RV fridge operates by removing heat rather than applying cold, that’s why it’s also known as an absorption fridge. It absorbs the extra heat rather than producing frigid temperatures. In a specifically built boiler, propane warms the water – ammonia mixture.
- The ammonia and liquid solution are then transported to the separator, in which the ammonia evaporates & flows through the refrigerator’s pipes while the water flows down to the absorber.
- As the ammonia fumes travel, they come into contact with a condenser. The condenser removes the heat and converts the ammonia to liquid form.
- The ammonia then moves to the condenser in the frozen element of your RV fridge, where hydrogen is added. This mixture is subsequently transferred to the condenser in the refrigerator’s fridge section. Any warmth in the freezer or fridge section is absorbed and transferred to the fridge’s outside, keeping the inside cool!
- Finally, after traveling through both evaporator coils, the ammonia reaches the absorber, is separated from the hydrogen, and is combined with water before being returned to the boiler.
RV refrigerators, unlike house refrigerators, do generally not include a built-in circulation fan. Install an RV fridge vent to assist move the air and keep the inside cool. Attach the fan to the evaporator fins of your RV’s fridge to assist spread cold air evenly throughout the fridge.
