If you own an RV, you’ve probably noticed that your dometic cooling units does not seem to be cooling as well as it used to. If your fridge is not cold, it may be time to replace your cooling unit.
There are many types of RV Cooling Units, and they can range from ducted systems to mini splits that fit inside your RV. Read on to learn about the different types of AC units and what to look for when buying a new one.
Typically, RVs come with two kinds of air conditioning systems: a dashboard system that looks similar to a passenger car, and a roof-mounted unit for the rest of the interior. A standard ducted unit draws power from your engine and battery to run, but the roof-mounted type runs on its own propane generator.
Ducted RV ACs are more efficient than their non-ducted counterparts, but they also tend to be more expensive. Nevertheless, if you are going to be running your RV on batteries and solar power for long periods of time, it’s important to make sure that you choose an efficient AC unit.
When choosing a ducted RV AC, you should consider several factors: the size of your rig, the space it’s taking up inside, and whether or not you want a unit that can cool a single room. The best ducted air conditioners will offer precise temperature control, a digital temperature display, and a remote so you can adjust the AC from anywhere in your RV.
Most ducted RV AC units are also very quiet, and can be controlled using your phone, tablet or voice assistants such as Amazon Alexa and Google Home. They also offer multiple zones, so you can control the temperature of each individual room.
Some ducted RV AC systems can switch between electric and propane power automatically. This saves you money, as propane can be pricey.
Dometic Refrigerators
The majority of RV refrigerators are made by Dometic, and their fridges look and work just like residential ones. They are easy to install, have variable power source compatibility, and have features that keep them closed while you’re traveling.
Absorption RV Refrigerators
Instead of using compressors, most of the RV refrigerators from Dometic and other manufacturers use a gas absorption cooling unit. This kind of system boils an ammonia-water mixture, and the ammonia vapor rises to the top of a coil system, where it condenses. The ammonia vapor then finds its way to the evaporator, where it makes water and ice.
Unlike compressor-type refrigerators, absorption units are quiet, have no moving parts, and use less energy than other types of fridges. They’re especially good for campers who don’t like to hear the noise of a compressor running.
When selecting an absorption unit, make sure that the model you buy has a high SEER rating. The higher the SEER, the more efficient your fridge will be.
A dependable absorption refrigerator will keep your food fresh for a very long time, and it’s more affordable than replacing the entire fridge. In addition to a high SEER rating, some of the best RV fridges have adjustable fans so you can adjust the circulation of the refrigeration system to reduce noise at night.
