• Micro DC Aircon

    Micro Cooling System for Air Conditioning - The World's Smallest Air Cooling A/C Unit

    The Micro DC Aircon is an air-cooled circulatory subsystem. It consists of a mini compressor (12V/24V/48V) with R134A coolant, the smallest condenser and radiator, evaporator, blower, filter drier, driver board, and other refrigeration parts.


    The micro compressor air conditioner is developed to satisfy the growing market that wants small cooling for compact and confined space cooling. The DC air conditioning module is frequently used in the cubby, EV (electric vehicle), helicopter, cab, and other small space cooling.


    RIGID DC air conditioning system uses our vapor compression technology to chill the air within an enclosed environment. The air removes the heat from the room and provides circulating chilled air without the need to change the user's existing system architecture.


    RIGID liquid chiller module is good for customers who are able to deal with system control. We provide a drive board together accordingly. Users want cooling subsystem modules only to integrate or assemble with their machine or equipment, in order to get a small cooling solution.


    End users’ control board can connect with RIGID drive board (included) to control compressor speed and get the best performance they needed. Except for standard chiller units, RIGID also custom-made or personalized small cooling modules to meet customers' special demands.

  • Rugged Miniature DC Aircon Unit


    RIGID is a miniature compressor innovation leader in China. We are creative and capture new technologies in compact cooling systems. It provides focused heat transfer and is especially useful for applications where space and weight are critical matters.

    RIGID air conditioning system consists of the basic 4 parts: a mini compressor, a micro-channel condenser, an expansion valve or capillary, and an evaporator. In the dc air conditioning system, the evaporator is typically a refrigerant-to-air heat exchanger which removes heat from the recirculating air. The blower is necessary to drive the airflow over the heat exchanger to drive the heat transfer.


    RIGID Micro DC Aircon demonstrates the good cooling performance of the vapor compression cycle for an air conditioning system. The benefits of the mini air conditioner unit include an ultra-small radiator and evaporator with an efficient blower. It has a very compact size in design. By using a mini compressor, it has features of lightest weight while excellent heat transfer performance as well.


    Input power is 150W with supposedly 450W of cooling. That's a COP of 3.0 W/W. It has a capillary tube, not an expansion valve. The compressor is variable speed, so it is energy efficient and saving. The Micro Aircon Unit contains an evaporator and a mini blower itself.


    The maximum cold air outlet temperature (from the evaporator) is 5℃ (41℉). For extreme hot areas like the Middle East or Dubai, the max ambient temp is 55℃ (131℉), that is our tropical 24V air aircon unit DV1920E-AC(T). so the tropical A/C unit is able to operate in higher temps.


    RIGID Micro DC Aircon is an ideal setup for van life, to cool a bed. For example, one of those ducted air blankets that hospitals use. Or a bed platform/mattress with holes to duct air to the bed. 250W of cooling is enough to keep two people comfortable when sleeping. With only 10A-15A of input power that could be reasonable.


    Of course, there are no standardized ratings cited, so actual performance may vary according to different environments.
