RV Mini Split is an air conditioner with a control panel installed inside the vehicle and the outdoor unit mounted on the roof or rear. It’s suitable for minibuses and vans.
Its core technology uses a 12V/24V/48V DC inverter compressor, directly powered by the RV’s battery, eliminating the need for a high-power inverter and resulting in extremely high efficiency.
Why is the RV Mini Split ideal for minibus/vanlife conversions?
No compromise on mobility or aesthetics
1. No added height: The roof has no protrusion, allowing easy access to underground parking garages, and minimizes wind resistance and noise.
2. Discreet appearance: The outdoor unit is hidden under or at the rear of the vehicle, making it look more like a regular vehicle, aligning with the Vanlife concept of stealth camping.
High energy efficiency and extremely low power consumption
1. DC inverter technology is key. The compressor speed is adjustable, and once the set temperature is reached, it maintains a low frequency, significantly reducing power consumption. 1. During nighttime sleep, power consumption can be as low as 200-500 watts, saving 30%-50% more energy than traditional fixed-frequency air conditioners.
2. This is a revolutionary improvement for precious RV power.
Superior Quiet Experience
1. The main noise sources (compressor, outdoor fan) are outside the vehicle. Inside, only the gentle breeze of the indoor fan is heard, providing a far superior sleeping experience compared to roof-mounted or portable air conditioners.
Flexible Installation Locations
1. Outdoor unit: Can be installed under the vehicle (requires protection), at the rear (spare tire rack location), or in the side skirt compartment.
2. Indoor unit: Can be flexibly installed above the driver’s cabin or in the living area, with relatively flexible duct connections.
How to Choose and Implement an RV Mini Split?
Confirm Vehicle Space
1. Measure the location where you plan to install the indoor unit (usually above the front seats or in the rear ceiling).
2. Most importantly: Determine the outdoor unit installation location. The undercarriage is the most common choice; ensure sufficient space and a secure mounting point (such as a beam).
Matching the Power System (This is a prerequisite!)
1. Even the most energy-efficient DC inverter air conditioner requires a stable power supply for continuous operation.
2. Recommended minimum configuration: At least 5 kWh of electricity (approximately 400Ah 12V lithium battery) + sufficient charging methods (such as DC-DC charging while driving, 300W or higher solar panels).
3. Calculation example: If the air conditioner’s average operating power is 400W, it will consume 4 kWh in 10 hours. Your battery needs a buffer; it cannot be completely depleted every time.
For van-to-motorhome conversions, DC inverter mini split-type air conditioners currently offer the best balance in terms of performance, energy efficiency, space, and aesthetics.
It solves:
1. The problems of increased height, wind noise, and overhead noise associated with roof-mounted air conditioners.
2. The problems of inefficiency, power consumption, and space occupation associated with portable air conditioners.
3. The problems of poor reliability and high installation risk associated with household air conditioners.
