Wuling Hongguang S air conditioner generates heat through engine coolant temperature. The automotive air conditioning system consists of refrigeration system, heating system, ventilation and air purification devices, and control system. Functions of automotive air conditioning: 1. Achieve cooling effect through continuous circulation of refrigerant; 2. Utilize engine coolant, waste heat or heat generated by burner combustion; 3. Draw external fresh air into the vehicle for ventilation and air exchange, which also effectively prevents windshield fogging; 4. Remove dust, odors, smoke and toxic gases from the vehicle air, freshen the cabin air, and humidify the interior air to increase relative humidity.
As a seasoned driver with over a decade of experience driving a Wuling Hongguang S, here’s my take on using the heating system. In winter, start the engine and let it warm up before driving—wait until the temperature gauge shows normal readings. On the control panel, there’s a temperature knob; turn it to the red zone for high heat. Then, turn off the AC button since it’s designed for cooling. Adjust the vents to blow toward the windshield or footwell for faster heat distribution and to prevent fogging. The process is simple and hassle-free, as the heating mainly relies on engine waste heat conversion without extra fuel consumption. If the engine is cold, it may take a few extra minutes of driving to warm up. For maintenance, regularly check coolant levels and the cabin air filter to ensure heating efficiency and comfort on long drives. It takes me less than a minute to set up, and once you get used to it, it’s effortless. Remember these tips to keep your car cozy in winter.
