RIGID: Your Unique Micro DC Air Conditioner Supplier
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. And 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 longer lifespan compared to traditional AC compressors.

Micro Air Conditioner Projects
There must be a heat emission hole in your system, you can use flexible tubes to connect the air conditioner unit.
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&off switch
All RIGID Aircon units are fully charged with oil and refrigerant before shipping. Users needn’t charge refrigerant. Afterwards, If you need to refill the compressor with refrigerant for maintenance, there’s one valve for a refrigerant refill.
RIGID dc aircon module is a sub-system, without an On & Off switch, need to wire up your own switch. DC Aircon unit is filled with refrigerant and oil before shipping.
Two white wires need to be closed or wire up to your On/Off Switch. Wires merge is On, separate is Off
The airflow is 27.8CFM.
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).
The green one was twinkling, the red one was not on means that the motor is on standby, please merge the two white lines first.
There are 4 ways to adjust 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.
1. Check if all wires are connected correctly.
2. Check DC power battery is fully engaged or not.
RIGID DC Aircon unit, as well as other compact liquid chillers, have been fully charged with oil and refrigerant before shipping. About thermostats, you can purchase them in our online store.

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 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.
The refrigerant again enters the compressor as a low-pressure vapour restarting the cycle.
The refrigeration cycle is demonstrated in the figure below.
