The World's Smallest Micro DC Aircon for Small Space Air Cooling 12V DC
RIGID Micro DC Aircon is a compact solution for small & confined space cooling, such as cabins, cuddy cabins, and electric vehicles, etc. The mobile A/C unit runs on power DC 12V/24V/ 48V, easily connecting to challenging confined spaces and extremely hot ambient!
This micro DC aircon is a sub-system that can be easily integrated into the customer's system and device. Its smallest footprint and lightest weight make it a perfect match for their compact space cooling. The portable Micro DC A/C is often used in small spaces such as RVs, vans, boats, camper trailers, vehicles, tents, and portable coolers, as well as for cooling electronic equipment and telecommunications systems. They can be powered by batteries or through a DC power source such as batteries, DC power, and solar power and are designed to be compact, lightweight, and easy to install.
RIGID Micro DC Air conditioner unit (DC stands for direct current) built with a BLDC (brushless direct current) miniature vapor compressor is a type of small-scale air conditioning system that uses a compact and energy-efficient compressor. The BLDC mini compressor is driven by an electric motor that uses direct current and doesn't have the mechanical brushes that generate friction, heat, and wear in traditional AC (alternating current) motors. This results in improved energy efficiency, lower noise, and a longer lifespan compared to traditional AC compressors.
RIGID Micro A/C units are ruggedized miniature air conditioning systems designed and developed specifically to meet the demands of the Electronic, van, camping, RV, and Motorhome operational environments. The battery-driven air conditioner cools, heats, or dehumidifies the air in a compact and confined space.

1. Does this micro air conditioner unit run inside the space, or does it need to be vented to outside of the cabinet?
- There must be a heat emission hole in your system; you can use flexible tubes to connect the air conditioner unit.
2. How do I connect the wiring diagram of the RIGID mini cooling system?
- All wires are ready before shipping. Users only need to do 3 steps:
1. Connect to the DC power supply
2. The drive board connects to the compressor
3. Connect to your system's on and off switch
3. How does one recharge/refill the refrigerant?
4. Does your company make a controller device for the unit, or do I need to wire up my switches?
- RIGID dc aircon module is a sub-system, without an On & Off switch, need to wire up your own switch. The DC Aircon unit is filled with refrigerant and oil before shipping.
5. I'm not sure what to do with the two white wires on the driver board. Do I have to have a switch on these two wires for the compressor to run?
- Two white wires need to be closed or wired up to your On/Off Switch. The wire merge is on, and the separate is off.
6. What's the airflow of the micro DC aircon unit?
- The airflow is 27.8CFM.
7. How to deal with condensate water?
- There is a drain for condensate water. You can collect the condensed water via a tube to a condensed collection tank (If you want to use the condensed water).
8. With the LED lights, only the green one was twinkling; the red one was not on.
- The green one was twinkling, and the red one was not on, meaning that the motor was on standby. Please merge the two white lines first.
9. How do you control compressor speed?
There are 4 ways to adjust the compressor speed.
1. Potentiometer speed control(already have)
2. 0-5v Speed control
3. PWM Speed Control
4. TTL communication port
The above 4 ways, the most common way to control the compressor is through potentiometer (included) adjustment.
10. The compressor is clicking on/off and does not get any colder than the ambient temperature?
1. Check if all wires are connected correctly.
2. Check whether the DC power battery is fully engaged or not.
11. Does your aircon unit include refrigerant and a thermostat?
12. How does it work for the payment and the shipping?
-PayPal, Credit cards, Bank transfer & L/C.
-DHL/UPS, By Air, By Sea are available.
-50% deposit in advance, balance against B/L or courier receipt.
13. What's the Warranty& maintenance?
One-year warranty, lifelong technical support.
14. Can we return the aircon when it has quality defects?
- Yes, we will 100% refund you if the purchase has any quality defects!
15. RIGID Micro DC Aircon Working Principle.
RIGID micro-refrigeration cooling System includes a miniature BLDC inverter compressor, driver board, condenser, evaporator, capillary, and other refrigeration parts. The compressor is the heart of a cooling system, it uses a small amount of energy to generate the refrigerant flow and heat transfer as desired.
RIGID developed a miniature BLDC rotary compressor that efficiently generates a significant cooling capacity within a small volume. The compressor takes in low-pressure refrigerant vapour and compresses it to high pressure and temperature.
The refrigerant undergoes an isothermal phase change (gas to liquid) and rejects heat to the ambient environment at high pressure within the condenser.
The refrigerant is throttled to low pressure and temperature (typically below ambient) through the expansion valve. Refrigerant enters the evaporator primarily as a liquid and again undergoes an isothermal phase change (this time from liquid to gas) as the evaporator absorbs heat from the environment.
