How do RV refrigerators work?
If you have an RV, then you know that having a refrigerator is essential for keeping your food and drinks fresh. But have you ever wondered how a refrigerator in an RV works?
Well, unlike a residential refrigerator that uses electricity, an RV refrigerator uses either propane gas or electricity to keep food and drinks cool. In this article, we will be discussing how an RV fridge that uses propane gas works.
How does a propane RV refrigerator work?
- Propane gas is burned in a burner assembly that is located at the bottom of the fridge.
- The heat produced by the burner is sent to the cooling unit, which is located behind the fridge.
- The cooling unit contains a series of pipes that are filled with ammonia, hydrogen, and water.
- The heated ammonia rises to the top of the cooling unit, where it mixes with hydrogen gas and condenses into a liquid.
- The liquid ammonia then flows down the pipes to the bottom of the cooling unit, where it evaporates and absorbs heat from the inside of the fridge.
- The absorbed heat is released at the top of the cooling unit, where it is dispersed into the air.
- This continuous cycle of heating and cooling keeps the inside of the fridge at a consistent cold temperature.
Advantages of a propane RV refrigerator
There are a few advantages of using a propane RV refrigerator:
- Propane gas is readily available at most RV parks, campgrounds, and gas stations, making it easy to refuel.
- Propane RV refrigerators are efficient and can run on a small amount of propane, making them an ideal choice for boondocking or dry camping.
- Propane RV refrigerators are silent and do not produce any noise, making them a preferred choice for RVers who enjoy a quiet environment.
How much propane does an RV fridge use?
The amount of propane a RV fridge uses depends on various factors such as the size of the fridge, outside temperature, and the frequency of use. On average, a 6-cubic-feet RV fridge that runs on propane can consume anywhere from 1 to 1.5 pounds of propane per day. Therefore, a standard 20-pound propane tank can last anywhere from 2 weeks to a month depending on usage.
| Fridge Size | Propane Usage (per day) |
|---|---|
| 4 cubic feet | 0.5 – 1 pound |
| 6 cubic feet | 1 – 1.5 pounds |

Factors affecting propane consumption in RV refrigerators
RV refrigerators are unique compared to traditional house refrigerators because they use propane gas as their primary fuel source. The propane gas is burned in a flame and absorbed by an ammonia solution, which causes the refrigerant to cool the fridge.
Propane consumption in RV refrigerators varies based on several factors such as:
- Exterior temperature: The hotter it is outside, the harder the fridge has to work to maintain the set temperature inside. This can lead to higher propane consumption.
- RV size: Bigger RVs need larger refrigerators, which means more propane consumption.
- Use Frequency: The more frequently you open your fridge and expose its contents to the outside temperature, the more energy it uses to cool down again.
RV Size
RV size is an essential factor to consider when examining propane consumption in RV refrigerators. The larger the RV, the larger the fridge, and the more propane it will consume. Big recreational vehicles are equipped with adequately sized refrigerators to accommodate the larger number of people they are designed to house. A large fridge in a small RV may consume more propane than necessary as it is oversized for the space.
Frequency of Use
Another factor that affects propane consumption in RV refrigerators is the frequency of use. The more frequently the fridge door is opened, the more energy it takes to cool back down. Keeping the fridge well-stocked can aid in reducing the frequency of use and consequently reduce propane consumption. It is also advisable to know what you want to get from the fridge before opening it to save energy.
Exterior Temperature
Higher temperatures outside make it harder for the fridge to maintain your desired temperature inside. The fridge has to use more energy to keep the temperature stable. Therefore, the hotter it is outside, the more propane gas RV refrigerators consume. It’s always a good idea to park your RV in a shady spot to keep its interior cool.
Summary
| Factors Affecting Propane Consumption in RV Refrigerators | Impact on Propane Consumption |
|---|---|
