Camper Refrigerator Types

Camper refrigerators come in three types: absorption refrigerators, compressor refrigerators, and residential refrigerators.

Absorption Refrigerators

Absorption refrigerators are the most common type of refrigerators found in RVs. They use evaporation and condensation caused by chemical reactions to keep the temperature cool. They can be powered by AC power, propane, or DC power. They take longer to cool down than compressor refrigerators and need to work harder in hot weather or high altitudes. They also require the RV to be level to function properly.

Compressor Refrigerators

Compressor refrigerators cool down faster than absorption refrigerators and can be more efficient. They can be powered by AC or DC power but cannot run on propane. They are also more flexible in terms of placement as they do not require the RV to be level.

Residential Refrigerators

Residential refrigerators are compressor refrigerators designed for residential use. They are usually larger than RV refrigerators and can only be powered by AC. They are also less durable than other types of refrigerators as they are not built to withstand the vibrations of RV travel.

Camper Refrigerator Power Sources

Camper refrigerators can be powered by a variety of sources, including propane, electricity, and DC battery. Modern camper refrigerators often use a combination of propane and electricity. Here is a detailed breakdown of the different power sources for camper refrigerators:

Propane

Propane is a common power source for camper refrigerators, especially for those who do not have access to shore power. It is considered useful for extended camping trips as it provides enough energy. However, one challenge with propane is that it may fail to work properly if the surface is not flat (more than 5 degrees incline). Additionally, there is a risk of gas leaks and subsequent explosions in the event of accidents.

Electricity (110 Volt)

Camper refrigerators can also run on 110-volt electric power. This option is advantageous when camping on dry land with access to electricity. However, it may not be useful when travelling to remote locations without power sources.

DC Battery

DC batteries can power camper refrigerators, but they may not be ideal for long road trips as they typically last for only 8-10 hours. The standard RV comes with four 6V batteries, providing about 200 amperes per hour, which is sufficient for a 20-hour road trip when fully charged. To increase battery life, incorporating an inverter is recommended. Additionally, solar panels can be used to trickle charge the batteries.

Combination of Power Sources (2-Way and 3-Way Refrigerators)

Camper refrigerators are available in 2-way and 3-way options. 2-way refrigerators can run on electricity (120V) or LP gas (propane). On the other hand, 3-way refrigerators offer more flexibility by utilising 120V, propane, and DC battery power sources. These refrigerators are ideal for those who frequently boondock or go dry camping as they provide efficient power options.
