RV refrigeration is one of the biggest conveniences available to full time RVers. There are a number of different fridges available in various sizes to fit your needs, from small portable ones to the large residential type found in some fifth wheels and Class A motorhomes.
Most RV refrigerators are absorption type, meaning that they boil a coolant (ammonia) to gas and then condense it back into liquid form again. This process takes a lot of energy, and that’s why most absorption refrigerators require a dual power source – propane gas to boil the coolant, and 12-volt DC electricity to initiate the cooling process. The best way to maximize your rv refrigeration is to optimize your temperature settings, make sure that the food you put in is already cold (as opposed to hot), and consider installing a fan inside your refrigerator to keep air circulating.
Some RVers have switched over to compressor style refrigerators, especially for those who rely on solar power and battery backup for their electrical needs. While these can be more expensive upfront, they do provide an excellent level of flexibility for camping in areas with no electricity or hookups. Other options include upgrading your batteries with lithium batteries, which charge faster and last longer than conventional batteries, and adding a pure sine inverter to the system to use stored electricity when the sun isn’t shining. rv refrigeration
