Truck air conditioner, also known as parking air conditioner, parking cooler, dc air conditioner, and roof air conditioner and backpack air conditioner. It works as backup air conditioning to make the electric AC work powered by battery directly instead of taking power from engine, widely used while parking to save fuel.
The cooling capacity is 7500-9000BTU/2000-2600W for 12V, 9000-10500BTU/2600 -3000W for 24V.
Launched in 2022 for the high-end market, the R5 model represents a significant upgrade. Its core innovation is the rotor compressor, which consumes 15%-20% less electricity than traditional scroll compressors while providing the same cooling power. Enhanced performance is achieved through a copper evaporator and brushless DC motorsfor both the condenser fan and blower. These brushless motors offer 3-5 times longer service lifeand significantly quieter operation (60-70dB)compared to brushed alternatives.
The system boasts intelligent control with multiple modes (ECO, Sleep, Strong) to optimize comfort and battery usage. Comprehensive fault diagnostics (EC, EF, E1-E9, H2-H4 codes)simplify troubleshooting. Designed for easy rooftop mounting, it maintains cabin space and ensures optimal airflow. Standard features include LED cabin lightsand options for 4 cold air outlets or automatic swing outlets. Regular maintenance, particularly keeping the condenser clean, ensures peak performance and longevity.
The DEFU R5 12V/24V Rooftop Air Conditioner provides efficient battery-powered cooling for:
Truck Sleeper Cabs: Essential climate control during driver rest periods, eliminating engine idling for significant fuel savings.
RVs & Campers: Comfortable cooling while parked or off-grid, powered by house batteries. Low power consumption extends battery life.
Commercial Vans: Crew comfort during breaks or stationary work (e.g., delivery, service vans), without engine noise or emissions.
Buses & Ambulances: Auxiliary cooling for drivers/crews during waits or standby, independent of the main vehicle system.
Specialized Vehicles: Climate control in ambulances, mobile workshops, or food trucks.
