12V/24V DC Rooftop Parking Air Conditioner | Scroll Compressor with Optional Brushed/Brush-less Motor-SR4

1. Miniaturized High-Efficiency Scroll Compressor
This unit is equipped with a compact high-performance scroll compressor, measuring 480*340mm. Compared with conventional compressors, the scroll structure operates with lower vibration, less mechanical loss and greater stability. Its compact footprint minimizes rooftop installation space occupation and fits most vehicle roof layouts. It sustains continuous long-hour operation without performance degradation, delivering reliable and consistent cooling output during prolonged parking.

2. Motor Optional for Compressor & Evaporator Fan
Both the compressor and evaporator fan support brushed and brush-less motor options to accommodate different budget ranges and operating conditions. Brushed motors offer proven reliability and cost efficiency for standard daily cooling demands. Brush-less motors eliminate carbon brush friction, reducing heat generation, mechanical failure and maintenance frequency. They deliver extended service life and stable performance, ideal for frequent and long-duration operation.

3. Optimized Copper & Aluminum Heat Exchange System
It adopts a high-efficiency hybrid heat exchange system with a copper evaporator and aluminum condenser. The evaporator features a standard size of 600*340mm. Copper provides superior thermal conductivity for rapid heat absorption and fast cabin cooling. The lightweight aluminum condenser offers excellent heat dissipation and strong resistance to corrosion and high temperatures. This structural combination maintains stable heat exchange efficiency in dusty, hot and bumpy working environments and prevents cooling attenuation.

4. Humanized Functional Configuration & Customizable Heating
Designed with practical human-centric features, the unit comes with auto-swing air outlets for even, dead-angle-free air circulation inside the cabin. Integrated LED lights provide auxiliary interior illumination. Additionally, a four-way valve can be customized to reverse refrigerant circulation, adding reliable heating functionality. This cooling and heating design adapts to changing seasons and enables all-climate cabin temperature control.

1. Stable Graded Power & Standard Cooling Capacity
voltage configurations deliver energy-efficient and well-balanced cooling performance. 12V model: 200-660W rated power, 1600W cooling capacity, offering low-load energy-saving cooling suitable for small and medium-sized cabins. 24V model: 200-800W rated power, 1800W cooling capacity, providing stable cooling output for heavy-duty trucks and large engineering vehicles. Both versions support long-term battery-powered idling-free operation.

2. Adjustable Wide-Range Air Volume
The unit features adjustable airflow ranging from 200 to 400 m³/h. Variable-speed airflow adapts to diverse cooling scenarios. Low airflow maintains steady cabin temperature with minimal power consumption, while high airflow accelerates indoor air convection to quickly dissipate heat and eliminate hotspots. This adaptive airflow system optimizes cooling efficiency and overall energy economy.

3. Low-Noise Comfortable Operation
Optimized mechanical structure and dynamic balance calibration for the compressor and fans effectively reduce vibration, friction and wind noise. The overall operating noise is maintained at 50-60dB. Smooth and quiet operation minimizes acoustic disturbance during parking rest, creating a comfortable and peaceful cabin environment for drivers during long-haul transportation and overnight stops.
