Using a portable refrigerator to power an air conditioner in an RV is not a practical or efficient solution. Refrigerators and air conditioners have vastly different power requirements and functionalities.
Power Requirements: Portable refrigerators typically run on 12V DC power, while air conditioners in RVs require a significant amount of power and typically run on 120V AC power or even 240V AC power for larger units. The power output of a portable refrigerator is not sufficient to meet the demands of an air conditioner.
Cooling Capacity: Portable refrigerators are designed to maintain a relatively small volume at low temperatures, typically used for storing drinks and perishable items. On the other hand, RV air conditioners are designed to cool a much larger space, the interior of the entire RV.
Compressor vs. Cooling System: Portable refrigerators use a small compressor or thermoelectric cooling system, which is not capable of providing the cooling power needed for an air conditioner. RV air conditioners use a larger compressor-based cooling system to cool the interior efficiently.
To power an air conditioner in an RV, you would typically rely on the RV's built-in electrical system, which includes an onboard generator, shore power hookup, or a combination of batteries, inverters, and solar panels. These systems are specifically designed to handle the high power demands of air conditioners and provide adequate cooling for the entire living space of the RV.
If you're considering adding an air conditioner to your RV, it's essential to ensure your electrical system can handle the extra load. If you have any doubts or need assistance, it's a good idea to consult with a professional RV technician or electrician to properly assess your RV's electrical capacity and make the necessary adjustments if needed.
