The Problem with Typical RV Air Conditioners
RV AC units that run on 120V AC electricity can be a challenge to power due to the limited power supply of an RV.
The typical RV AC unit is 13,500 BTUs and requires a lot of power to start up and run.
This can cause problems if you are plugged into shore power or running off a generator, as it may draw too many amps and trip the breaker.
Additionally, running off your RV’s battery bank requires an inverter to convert the battery’s DC power to run the AC unit.
This can strain your battery bank and limit how many other appliances you can use while running the AC unit.
Understanding 12 Volt RV Air Conditioners
With the increasing popularity of off-grid van life and the constant search for energy efficiency, 12V RV air conditioners have emerged as a practical solution.
These units run on your onboard battery bank, making them perfect for adventurers without access to shore power.
They’re also known as camper van air conditioners and come with several perks: using less power, operating quietly, and eliminating the need for a generator.
There are three main types of 12V RV air conditioners:
- rooftop,
- portable, and
- mini-split.
These differ from typical RV air conditioners that run on 120V AC power.They’re ideal if you’re using lithium batteries as your power source.
When selecting a 12V RV air conditioner, consider the cooling capacity, power consumption, and ease of installation.
How 12V RV Air Conditioners Work
A 12V van air conditioner blows hot, dry air through a moistened cooling pad.
The wet pad can absorb the heat. This, in turn, leads to water evaporation, which in turn cools your RV.
The two main types of 12V air conditioners are DC and AC, with DC units being more efficient for RV use due to their lower power consumption.
The main difference between these types lies in how the compressor is powered, the power drawn from the electrical system, and the maximum cooling temperature they can achieve.
You might have encountered DIY cooling system kits like the Rigid/Campelify Micro 12V Cooling System or the Campelify 12V Cooling System.
These compact kits include a mini rotary compressor, condenser, driver board, evaporator, fan, heat exchanger, and a capillary mini rotary compressor.
They are suitable for small, compact campers like off-road campers and vans or even for cooling a single room in a medium-large RV.
Benefits of 12V RV Air Conditioners
The most significant benefits of 12V RV air conditioners are their reduced power consumption, quiet operation, and independence from generators.
