How Does a Refrigerator Work in an RV?
The refrigerator in your RV works just like a regular residential refrigerator, but with some added features. The main difference is that an RV refrigerator has two different cooling systems; one for propane gas and one for electric power.
Depending on the type of fuel you choose to use, the system will adjust accordingly so that it can keep your food cold.
The coolant in this system doesn’t use any electric power, and is completely self-sustaining.
For two-door refrigerators – like the ones in most RVs – the cooling process happens differently. These types of refrigerators use a compressor to keep food cool inside; they’ll use either electricity or propane depending on what’s available.
The compressor pumps a refrigerant through the coils of the refrigerator, which absorbs all the heat and cools down the air inside. This method is much more efficient than absorption cooling but does require a more powerful energy source.
Lastly, there are some newer RV refrigerators that use a compressor-less design to keep your food cold. These types of refrigerators use a system called thermoelectric cooling to generate cold air inside the fridge without the need for an external energy source. This is a great option if you’re looking to save on energy costs while camping!
3 Power Sources for RV Fridges
There are three ways to power your RV refrigerator: electricity, propane gas, or 12-volt DC power. The system will change depending on which fuel source you choose.
Electricity is one of the most reliable and efficient ways to power your RV refrigerator. This method uses a compressor to cool the air inside the fridge, and it will run as long as you have access to an electric hookup at your campsite.
Propane is another type of power that can be used for RV refrigerators. If you don’t have access to electricity or 12-volt DC power, propane can be used instead.
The system works by burning the gas in order to create a cooling reaction inside the refrigerator, and it will run as long as there is propane in your tank.
Lastly, you can use 12-volt DC power to power an RV refrigerator if you don’t have access to either electricity or propane. This is usually done using a special converter that converts 12-volt DC power into 120-volt AC power, which can then be used to run the refrigerator motor. [2]
How Does an Absorption RV Fridge work?
An absorption RV fridge is a type of refrigerator that doesn’t require any external energy sources to run. This type of refrigerator relies on an absorption process to keep your food cold.
In this system, ammonia gas is mixed with hydrogen and water to create a closed loop that moves through the refrigerator and cools down any food stored inside.
How Does A Propane RV Fridge work?
A propane RV fridge uses propane gas to keep your food cold instead of electricity. The propane is burned to create a cooling reaction inside the fridge.
The system uses what is called a catalytic converter, which helps regulate the amount of heat that is released as the propane is burned. This helps keep the temperature inside the fridge consistent and prevents it from getting too cold or too hot.
How Does A 12-Volt RV Fridge work?
A 12-volt RV fridge is powered by a special converter that converts 12-volt DC power into 120-volt AC power, which can then be used to run the refrigerator motor.
The converter helps control how much electricity goes through the system. It also stops the fridge from taking too much power. This helps keep your food cold without using up all the battery power in your RV. [2]
The Full Cooling Process
The process for cooling an RV refrigerator is complex, but it all comes down to using energy to cool the air inside.
Depending on which fuel source you choose (electricity, propane gas, or 12-volt DC power), the system will use that energy to create either absorption cooling or compressor cooling in order to keep the air inside cold.
Types of RV Refrigerators
Dual Electricity/Propane Refrigerator
The dual electricity/propane refrigerator is a great option if you want to use both energy sources. This type of fridge can run on either electricity or propane, giving you the ability to choose which fuel source works best for your needs.
Battery-Powered Refrigerator
The battery-powered refrigerator is another great option for those that don’t have access to either electricity or propane. This type of fridge runs on 12-volt DC power, so it can be used even when you’re not near an electrical outlet.
Mini-Fridge
You can also get a mini-fridge to use in your RV. This type of fridge is smaller and more compact than the other types, but it still provides enough space to keep your food cold.
Two-Way vs. Three-Way RV Fridge
Two-way fridges can only run on either electricity or propane, while three-way fridges can also use 12-volt DC power. The type of fridge you choose will depend on what kind of fuel source you have access to at your campsite.
Keeping Your Fridge Cool
There are a few tips to keep in mind that will help ensure your food stays cold.
- First, make sure to limit the number of times you open and close the door. This will help keep the temperature inside consistent and prevent any warm air from entering.
- Also, make sure to keep the fridge away from direct sunlight. Sunlight can increase the temperature inside, so it’s best to store your fridge in a shady area.
- Finally, be sure to check and replace any insulation that may have become damaged over time. This will help keep the cool air inside and prevent warm air from entering.
Ambient Temperature and Your Fridge
The ambient temperature outside can also have an impact on your fridge and the amount of energy it uses. If it’s too hot, your fridge may need to work harder to keep the air inside cool, so make sure to monitor the temperature outside and adjust accordingly.
Keeping Your RV and Fridge Level
It’s important to make sure your RV is level when you park it. This will ensure the cooling system works properly and that your food stays cold.
If you see any signs of unbalanced or uneven weight distribution in the RV, be sure to adjust it before turning on the fridge. [1]
Driving With Your Fridge Running
When you’re driving with your fridge running, make sure to check the power gauge. Your RV’s battery won’t last forever, so checking the gauge can help you make it last longer.
How Much Propane Does an RV Fridge Use?
The amount of propane your RV fridge uses will depend on a few factors, including the type of fridge you have and the size of your RV. Generally speaking, an RV fridge can use anywhere from 1 to 2 gallons per 24-hour period.
However, this number may be different depending on the specific model and make of your fridge.
Tips For Your RV Refrigerator
To get the most out of your RV fridge, there are a few tips you should keep in mind. Be sure to check the insulation and make any necessary repairs.
Clean out the vents on a regular basis so that air can move freely throughout the unit. Finally, always remember to turn off your fridge when it’s not in use to conserve energy.
With the right knowledge, you can enjoy all of the benefits a refrigerator has to offer without any worries.
