Both gas and electric RV refrigerators have their pros and cons, and the choice ultimately depends on your individual needs and preferences.
For example, gas-powered absorption units can be more affected by the temperatures around them, while electric RV refrigerators tend to provide more consistent cooling and lower temperatures.
Additionally, gas-powered refrigerators may be more suitable for boondocking or dry camping, where there is no access to electricity.
Understanding RV Refrigerators
RV refrigerators are an essential part of any RV, providing a way to keep food and drinks cool while on the road. These refrigerators work differently than household refrigerators, primarily because they are designed to run on both gas and electric power.
The cooling process of an RV refrigerator is based on the absorption mechanism, which uses heat to create a cooling effect. This process is different from the compressor-based cooling process used in household refrigerators. The absorption process is quieter and more efficient, making it ideal for use in an RV.
An absorption refrigerator uses a combination of ammonia, hydrogen gas, and water to create a cooling effect. The ammonia is heated and vaporized, then condensed back into a liquid state, releasing heat in the process. This heat is then absorbed by a hydrogen gas mixture, which cools down as it absorbs the heat. The cooled hydrogen gas mixture is then circulated through the refrigerator, cooling down the interior.
RV refrigerators can run on both gas and electric power. When running on gas, the refrigerator uses propane as its fuel source. When running on electric power, the refrigerator uses either 120-volt AC power or 12-volt DC power from a battery. Electric RV refrigerators tend to provide more consistent cooling and lower temperatures, ensuring your drinks really are ice cold and helping your food last longer on every trip.
One thing to keep in mind is that RV refrigerators can take some time to cool down once they are turned on. Gas-electric refrigerators, in particular, can take 3-6 hours to cool down once you start them. Additionally, they must be level in order for the fridge to work properly. Over-stuffing can also reduce efficiency.
Types of RV Refrigerators
When it comes to RV refrigerators, there are a few different types to consider. In this section, we’ll take a look at the most common types: gas refrigerators, electric refrigerators, and residential refrigerators.
Gas refrigerators, also known as absorption refrigerators, are a popular choice for RVers. These refrigerators use propane as their primary source of energy and can also run on electricity. They are typically 2-way refrigerators, meaning they can run on either propane or AC power.
One of the benefits of gas refrigerators is that they don’t require any external power source, making them ideal for off-grid camping. However, they can be less efficient and may not cool as quickly as electric refrigerators.
Electric refrigerators are becoming more popular among RVers due to their efficiency and ease of use. These refrigerators run solely on electricity and are typically 2-way or 3-way refrigerators, meaning they can run on AC power or DC power (battery) in addition to propane.
Electric refrigerators are generally more efficient than gas refrigerators and can cool more quickly. However, they do require an external power source, which can be a drawback when camping off-grid.
Residential refrigerators are becoming more common in RVs as well. These refrigerators are similar to those found in homes and run solely on AC power. They are typically larger and more spacious than gas or electric refrigerators, making them a popular choice for full-time RVers.
However, residential refrigerators require a significant amount of power and may not be suitable for off-grid camping or boondocking. They also tend to be more expensive than gas or electric refrigerators.
Overall, the type of RV refrigerator you choose will depend on your camping style and needs. Gas refrigerators are ideal for off-grid camping, electric refrigerators are efficient and easy to use, and residential refrigerators offer more space and convenience. It’s important to consider your power needs and camping style before making a decision.
How RV Refrigerators Work
RV refrigerators work differently from traditional household refrigerators. The primary difference between the two is the source of energy. While household refrigerators derive power from electricity, RV refrigerators can run on propane or electrical power.
RV refrigerators use a combination of propane, ammonia, and hydrogen gas to cool the interior. The process begins with the propane gas being lit and heating up the ammonia. The heated ammonia rises and enters the evaporator, where it meets hydrogen gas. The hydrogen gas absorbs the heat from the ammonia and evaporates, creating a cooling effect.
The cooling process continues as the ammonia and hydrogen gas mixture enters the condenser. The heat generated from the cooling process is released through the condenser, and the ammonia returns to its liquid state. The cycle then repeats itself, with the liquid ammonia returning to the evaporator to start the process all over again.
When running on electrical power, RV refrigerators use a heating element to create heat instead of a propane flame. The rest of the cooling process remains the same.
It’s worth noting that RV refrigerators can take longer to cool down than traditional household refrigerators. This is because they have a smaller cooling unit and rely on the outside temperature to dissipate heat. Additionally, RV refrigerators may struggle to maintain cool temperatures in extremely hot weather.
