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 7000-8500BTU/600-2000W for 12V, 8500-9500BTU/2000 -2600W for 24V, 8500-9500BTU/2000-2600W for 48V-72V. The heating power(optional) is 500W for 12V, 500-1000W for 24V, 500-1000W for 48V-72V.

DEFU’s SR1 rooftop parking air conditioner delivers efficient, battery-powered climate control for trucks, RVs, vans, and light commercial vehicles. Available in two specialized versions —l cooling-onlyand dual-mode (cooling + heating)—it adapts to diverse climates and applications, from desert trucking to winter RV camping. Operating on DC 12V/24V/48 -72V vehicle batteries, it eliminates engine idling while delivering up to 2600W (9500 BTU) cooling capacityand optional 1000W heatingin dual-mode configurations.
With an operating range between 16–43°C, its scroll compressor and sine wave controllerreduce current draw to just 15A, maximizing battery life during extended operation. The dual-mode variant provides year-round comfort, with heating capabilities reaching 500W (12V models)or 500-1000W (24V/48-72V models)—ideal for sub-zero environments.
Durability meets innovation through an upgraded 7-blade condenser fan and oversized aluminum condenserthat accelerate heat dissipation. Housed in a corrosion-resistant ABS/PP cover tested to withstand adult weigh, the SR1 supports 20+ customizable colors. Environmentally conscious R134a refrigerant and COP ≥2.5 efficiency minimize ecological impact.
The DEFU SR1 Rooftop Air Conditioner delivers battery-powered climate control for diverse scenarios:
1. Long-Haul Trucks:
Rest Period Comfort: Maintains sleeper cab temperatures (15–30°C) during mandatory breaks using 12V/24V batteries, eliminating engine idling.
All-Weather Readiness: Dual-mode modelsprovide 9500 BTU cooling in deserts and 500–1000W heatingfor sub-zero conditions.
2. RVs & Off-Grid Camping:
Solar/Battery Operation: Runs on 48–72V systems for extended wilderness stays.
Compact Durability: PP/ABS cover withstands road debris; ideal for desert expeditions or mountain trips.
Global Suitability :
Certified (CE/EMC) for extreme climates (16–43°C), widely adopted in Middle East, Southeast Asia, and the Americas.
