Things To Consider When Buying a Refrigerator for Your RV
The first thing that you need to consider when buying a refrigerator for your RV is the size. Although RVs are quite spacious, you can’t buy a fridge without looking for a place for it inside your vehicle first.
It’s very important to maximize the space of your RV and to designate a spot for your refrigerator. Make sure that the area is enough for the closing and opening of the fridge’s door as well as comfortably adding or taking out supplies.
Once you’ve figured out the spot for your fridge, it will help you pick out the size that would be ideal for it. The next thing you need to concern yourself with is the amount of food that you need to stock up on.
You can determine this by the number of people who’ll be traveling in the RV as well as the number of days you have to stay off-grid. If you usually travel solo, then there’s no need to get a huge refrigerator. A small, portable fridge should enough for these ventures.
After you choose the right size of your fridge, depending on its use, the capacity of your RV refrigerator needs to be the next factor under consideration. The capacity of an RV fridge doesn’t only refer to the amount of food it stores.
It also means the maximum time all the features of the fridge will be available to you. As the concept of traveling in RVs becomes increasingly popular around the world, technology is also stepping up.
The recent RV refrigerators come with several new advancements and high-end features that make traveling in the RV very comfortable and sometimes even luxurious. An example of these technological advancements includes the option of two doors and the reversible feature in fridge doors.
Some refrigerators now come with an ice maker, which keeps all your beverages icy cold. Some give you the option of automatic defrosting and temperature control, which makes it very easy to store and use frozen items.
You’ll have to specify your needs when looking for a solar RV refrigerator. Just going after the latest features may not be the best option because they can reduce the functioning hours of your fridge when it’s completely charged.
Heavy features such as thermostats and flame indicators reduce your battery time, but if safety is your top priority, then you should go for them. To deal with the battery problem, you should buy a refrigerator that has more than one power source so that you always have an alternative.
Once you’ve settled on a size, capacity, and required features in an RV fridge, now you need to make a budget for it. The price of the freezer is another important factor that you need to consider before buying one.
If you have a brand in mind, make sure that their products fulfill all your requirements. We would strongly recommend buying a fridge that comes with a warranty. The price of RV refrigerators varies depending on the features that it offers.
The more high-end features you look for, the price would increase. An RV fridge is an investment and one you’ll be living with for a long time. So, if you have the budget, make sure you buy one without compromising on the quality.
Another important factor to consider while buying refrigerators is the material. Ask about the manufacturing material used for the making of the refrigerator. Make sure it’s not made up of any material which has the potential of harming your RV or its environment.
You need to make sure that your refrigerator is compatible with your vehicle. The material of a refrigerator has an impact on its weight and overall efficiency. Always ask the sales representative about the quality and constituents of the material used in manufacturing.
What’s an RV Refrigerator?
RV refrigerators are similar to domestic fridges, but they are designed to function in the mobile environment of a vehicle. Recreation vehicle, or RV, is quite popular across America and other countries. It’s a perfect vehicle for a road trip with friends or family.
Its spacious size allows for the comfort of its inhabitants. Unlike a car or a van, you can have beds and a working kitchen in this wonderful moving vehicle. That’s why most families choose RVs for a road trip.
Since RV provides so much room, then why not use it to make your travels more comfortable? Because of this reason, many brands have started introducing appliances and tools that will help upgrade your RV.
However, the impact of these additions needs to be considered carefully for the long life and optimum performance of your beloved vehicle. Now that you have understood the RV and its functions in full detail, it will be easy to understand an RV refrigerator.
RV refrigerators are different from domestic fridges because they are specially designed to operate and last in the mobile environment of an RV. That’s why factors like size, weight, capacity, power source, and other features are designed to last a long time in the RV.
How Is an RV Refrigerator Different From a Standard Fridge?
Many RV users may believe that an RV refrigerator is just like any standard fridge that we use in our regular lives. However, that assumption couldn’t be farther from the truth.
Along with the difference in size, design, and capacity, an RV fridge also differs from regular fridges in functions and operations. But how?
A standard fridge applies the cycle of vapor compression to operate. When the constriction of refringent vapor occurs, the temperature and pressure of the refrigerator go up. Then the hot gas collects in the coil of the fridge.
When the coils come in contact with the low-temperature environment of the refrigerator, the hot gas turns into a liquid. The newly formed liquid then flows through the expansion valve and reaches the evaporator coils of the refrigerator.
When the temperature goes up again, the refrigerant liquid turns into a gas again. Then, the gas flows back inside the compressor. This cycle repeats over and over again.
On the other hand, RV refrigerators function quite differently. Since an RV is continuously in motion, the refrigerators are adapted to this environment by making changes to some processes, which help shed some weight off them and make them efficient.
Instead of using a compressor to cool the environment, an RV fridge incorporates the process of absorption refrigeration. It is a cycle of chemical processes involving hydrogen gas, water, ammonia, and sodium chromate.
The mixture of these chemicals flows through the pipes of the freezer to keep it cool. The cycle is mainly fueled by gravity.
What Are the Types of RV Refrigerators?
RV refrigerators differ from each other in many ways, and there’s no single classification system to differentiate them in types. Some refrigerators differ in their sources of power. Most RV fridges come with a two-way power supply.
They either use an 11-v electric power source or utilize propane gas to power up. There are also a few brands that offer RV fridges that have a three-way power supply.
They either come with an additional feature of using the 12v power provided by the batteries of the RV, or they have the option of recharging with solar power. Apart from the power source, different RV refrigerators come with different features.
Some are big in size, while others are small and portable. The bigger refrigerators also come with double or reverse doors, if that’s your preference. Some RV fridges also come with an ice maker with the option of automatic defrosting and temperature control, which frees the user from having to do any manual work.
Technological advancements have now introduced electric controls for your RV fridge. It makes it convenient for users to navigate and maintain the operational systems of the fridge.
Many fridges have versatile space for the storage of supplies, which keeps them fresh through long distances and time. You can also choose to buy a fridge that comes with an advanced thermostat and other features like a flame indicator.
Almost nothing is impossible to have if you’re willing to pay the price for it.
Why Should You Get an RV Refrigerator?
Keeping in mind everything that we’ve discussed so far, your RV needs a fridge that is specifically designed for operating in its environment. A regular fridge wouldn’t be as efficient when used in an RV and can pose a lot of problems for you during your trip.
The main factor that makes RV fridges better is their power supply. It is designed to withstand and be compatible with your vehicle’s system. Moreover, a standard fridge will utilize a lot of space and battery power.
Unlike a regular fridge, the material used to manufacture the RV fridge, it’s size, capacity, and other features are all compatible with the RV. The RV fridge makes your trip comfortable and doesn’t cause problems on the road.
It’s essential to choose appliances for your RV based on their compatibility with them. It will ensure that the systems of RV are not affected by incompatible additions.
How Do Keep RV Refrigerators Cold?
Sometimes refrigerators stop cooling down as efficiently. This happens due to various reasons like a lack of power supply, extremely hot and humid weather, or poor maintenance.
In order to fix this problem, you first need to make sure that you’ve been performing all the required maintenance tasks regularly. If it’s not a maintenance problem, and your fridge doesn’t feel cool enough, then you can take one of the following measures:
An RV fridge fan will keep the air cool inside your refrigerator. It will help fast-track the cycle of cooling, especially in the lower compartments of the fridge. The fridge fan usually comes with a powered battery, so it wouldn’t require a power source for occasional use.
Vent Fan for the Fridge
A vent fan for your RV fridge is a great idea because it will decrease its power use by assisting it in expelling out the hot air. Make sure you place the vent fan on the fridge’s vent. It comes with a battery and can also be powered by the RV’s electric system.
Benefits of a Solar RV Refrigerator
The primary selling point of solar RV refrigerators is that they are highly energy efficient. They run on limited solar power and operate their compressor systems very efficiently.
RV solar refrigerators mostly have thick and highly efficient insulation system. It makes it easier to bring the fridge’s temperature down very quickly. Solar refrigerators that come in the chest type design don’t require heavy amounts of power to function efficiently.
Two Power Modes
Most solar-powered refrigerators come with the ability to function on two power modes, including 12V DC power and 11V AC power. It makes it easy to connect them with your solar power bank.
