Turn on the heating air conditioning system of the vehicle, do not turn on the air conditioning button, adjust the temperature of the air outlet to the lowest temperature area, and then adjust the angle and air volume of the air outlet, so that the natural wind of the vehicle can be utilized, and the circulation system needs to be adjusted to external circulation.
Matters needing attention in the use of automobile air conditioner
The air outlet direction of the air conditioner can be adjusted at will. Some car owners do not pay attention to adjusting the blowing direction of air conditioner when using air conditioner, which is not conducive to achieving the best effect of air conditioner. According to the principle that the cold air sinks and the hot air rises, the correct way should be that the air outlet is upward when the cold air is turned on and downward when the heating is turned on.
Leave the air conditioner on for a long time. Some car owners always turn on the air conditioner after getting on the bus, but using the air conditioner for a long time will make the condenser pressure too high and cause losses to the refrigeration system, because the air conditioner is a heavy burden to the engine, which is itself a heater, not to mention in high temperature weather.
Don't smoke in the air-conditioned car. Because of smoking in the car, the smoke can't be discharged at once, which stimulates the eyes and respiratory system and is not good for the body. If you smoke, you should adjust the air conditioning ventilation control to the discharge position so as to discharge the smoke from the car outside.
Don't rest or sleep for a long time in a parked car with air conditioning. Because of the good sealing inside the car, once the car stops, the ventilation inside the car is poor. If you turn on the air conditioner to rest or sleep at this time, it is likely that the CO gas discharged from the engine will leak into the car, causing poisoning or even death.
