Can RV Refrigerators be Recharged?
RV refrigerators are designed differently from your home refrigerator and require a specific approach to recharging. While some people might suggest that recharging is not possible or recommended, with the proper knowledge and tools, it can indeed be accomplished.
- RV refrigerators can be recharged, but caution is crucial.
- Recharge involves replacing the ammonia-based cooling unit.
- DIY option exists, but hiring a professional is safer.
- Recharging may not be cost-effective for older refrigerators.
- Recharging an RV fridge demands careful handling and consideration.
Wouldn’t you enjoy relaxing and having delicious snacks with your family at a beautiful campsite in your treasured RV? Who doesn’t?
I am sure everyone does. Today, all RVs come with built-in refrigerators so that you and your family don’t miss out on your favorite snacks and enjoy a seamless camping experience.
RV refrigerators can preserve food and ensure freshness for the RV user anytime and anywhere.
Today, RVs come with high-tech appliances built to give you a homely feeling with maximum comfort.
So, can RV refrigerators be recharged? Yes, but only if you have a compressor refrigerator with an open system. These can be restored quickly, cheaply, and with minimal inconvenience. Read on to find out more!
Before that, let’s learn about the different RV refrigerators available.
RV Refrigerator Types
RV refrigerators are available in three different types:
- Thermoelectric,
- Absorption, and
- Compression Fridges.
Though all three have benefits, only compression fridges allow you to recharge them.
Therefore, you should be mindful of the type of refrigerator installed in your RV.
Thermoelectric RV Refrigerator
This RV refrigerator functions on the Peltier principle. It pumps heat electronically.
This fridge has two ends. The fantastic end is inside the cooler, keeping the food cold. The hot end is outside, where it disperses heat into the air.
The process is straightforward and requires the pumping of heat energy outside the fridge to reduce the temperature inside.
These refrigerators are insulated, so heat doesn’t leak inside a lot.
If your thermoelectric fridge is not functioning correctly, it’s better to replace them. These fridges do not have coolants to recharge.
Moreover, replacing the fridge’s components is also cumbersome.
Thermoelectric RV fridges are not very efficient. They are only about 10 percent more efficient than your home refrigerator.
These fridges are more suitable for short trips where you need beverages and food to stay cold for a few hours.
Absorption RV Refrigerator
Absorption refrigerators are the most common type of RV refrigerators. These fridges don’t require electricity to function.
Your home refrigerator uses a compressor to keep things fresh and cool. On the other hand, this refrigerator uses ammonia, hydrogen gas, and water.
The Absorption fridge has several tubes for transferring the elements mentioned above, inducing chemical reactions.
These refrigerators replace electricity with propane. The propane heats the ammonium solution. This, in return, leads to the periodic evaporation and condensation of these reactions, thereby keeping your food fresh and cool.
With these freezers, you should be mindful of leakages as they are hazardous.
The following are some symptoms you should be aware of:
- The smell of ammonia inside your fridge
- Rusty water at the metal tubes in the rear end of your fridge
- Leakage of yellow or green-colored powder
- Sudden heating up of the fridge
- Loud gurgling sounds coming from the fridge
You should get your cooling unit checked by a professional if you notice any of the symptoms mentioned above.
A significant drawback of these fridges is that you cannot recharge them as they use ammonia. They are sealed and can’t be refilled.
However, the Absorption refrigerator’s cooling unit can get a replacement in case of any harmful leakage.
I would recommend you get a professional diagnosis before replacing your cooling unit. Finding the correct cooling unit for your fridge might not be easy.
Therefore, I would suggest you seek a manufacturer’s expertise.
Absorption refrigerators have higher efficiency and last longer than the previously mentioned ones. These are ideal if you want to enjoy the whole weekend with your family.
Compression RV Refrigerator
These are the fridges present in your homes mainly. Compression fridges use a compressor for cooling the refrigerator.
These refrigerators use a refrigerant gas that turns into a liquid at low temperatures. As the compressor starts, it draws in the cold refrigerant gas in liquid form as it leaves the evaporator.
During this stage, the temperature inside the fridge goes down, making it cold.
The compressor then compresses the gas, which afterward goes to the condenser. Lastly, this absorbed heat goes into the surroundings.
This process is repeated continuously to preserve your food and maintain its freshness.
The best part about these refrigerators is that you can quickly recharge them without a painful process. Just make sure you are getting it restored by a certified professional.
If you plan to buy one for your RV, check if the fridge has an open or closed system. In the latter case, you cannot have your fridge recharged.
Even though these refrigerators are super convenient to handle, they do have some cons.
You might be risking the warranty of your compression refrigerator by recharging it. Therefore, you should research warranty claims before investing in these refrigerators.
It would be best to remember that the refrigerant might escape gradually and eventually end up during the recharging process.
So make sure your refrigerator is in safe hands before making this decision.
These refrigerators are affordable and require low maintenance, provided you take good care of your refrigerator.
They last longer than other types and have the highest efficiency range of about 60 to 70 percent.
RV Refrigerator Maintenance and Usage Tips
No matter what type of refrigerator you buy for your RV, its maintenance is pivotal for its long life.
Here are some easy ways you can implement and ensure smooth functioning of your refrigerator:
1. Turn It On Beforehand
I suggest you turn your fridge on the night before your camping trip. Typically, freezers need at least six hours to cool down.
2. Begin with Cold Items
Start loading cold items first, such as ice or cold beverages, to help your fridge begin cooling faster.
3. Don’t Overpack It
Your fridge needs space so that the cold air can flow between items. Therefore, make sure you are keeping some space.
4. Install A Fan
During hot weather, your refrigerator can get warm quickly. You can reduce the surrounding temperature with a fan.
5. Check The Seals
You should regularly check for loose seals or leakages in tubes. Either of these can cause a loss of cold air in the environment. Make sure you replace them often.
6. Keep It Functional
If you let your fridge sit idle without running, it can get severe damage. Ensure you run it for a few hours weekly if it is not in use.
7. Clean It Regularly
It would be best to keep your cooler clean so it doesn’t smell when not in use. You should clean all the vents and thaw the fridge regularly.
8. Change The Settings
All refrigerators come with different modes that fit each weather condition. Don’t forget to change the settings for different weather.
You can shift your fridge’s cooling to low cooling in winter. And in summer, you can change it back to high cooling.
Doing so will improve the functioning of your fridge and will enhance its longevity.
Does the RV Refrigerator Need a Battery?
Most RV refrigerators, especially those running on propane, require a modest 12-volt DC power. This power is essential for operating the control panel and the igniter.
The source of this power can be twofold. It can be derived directly from the RV’s battery or a converter that modulates 120-volt AC power to 12-volt DC power.
This typically occurs when the RV is connected to an external power supply, often called shore power.
Final Words
RV refrigerators are an essential feature of every RV. They enhance the fun of your camping experience so that you can create unforgettable memories.
Yes, it is possible to recharge RV refrigerators, although this process should be cautiously approached. Recharge typically requires technical expertise to replace the ammonia-based cooling unit.
While a do-it-yourself option is available for those comfortable with such tasks, hiring a professional to handle the job is generally safer and more reliable.
This is especially true given that recharging an RV refrigerator involves careful handling and consideration due to the potential risks of mishandling the cooling unit.
Additionally, it’s worth noting that recharging may not always be the most cost-effective solution for older refrigerators, as the cost of replacement parts and labor may outweigh the value of the appliance itself.
Therefore, while “Can RV Refrigerators be Recharged?” can be answered affirmatively, weighing all factors before deciding on this course of action is essential.
