Set the refilling capacity, time, and type on the refrigerant recovery and refilling machine; 5. The refrigerant recovery and refilling machine will automatically start adding refrigerant. Functions of car air conditioner: 1. Achieve cooling effect through continuous circulation and transformation of refrigerant; 2. Draw in fresh external air for ventilation and air exchange, preventing window fogging; 3. Use engine coolant, waste heat, or heat generated by a burner as a heat source for heating, which is then blown into the car by a blower to raise the temperature and achieve heating effect; 4. Remove dust, odors, smoke, and toxic gases from the car air, making the air fresh, and humidify the car air to increase relative humidity.
