The car's warm air blows the heat of the warm air small water tank into the cab with the help of the blower. If the air volume is insufficient or the distribution of cold and hot air is not good, the heat of the small warm air tank cannot be radiated, resulting in the temperature of the warm air not coming up.
Parking heating system is an independent auxiliary heating system on the vehicle, which has no direct connection with the engine. It can be used after the engine is turned off and can also provide auxiliary heating function during driving. Parking heating system overcomes the limitation that ordinary vehicle heating system depends on engine, and can improve the heating speed of vehicle.
Pay attention to details when using parking air conditioner in summer.
It is suggested that the air outlet of parking air conditioner should be upward, and the direction of air outlet should not be adjusted at will. The correct way is to open the air outlet when turning on the air conditioner, because the air conditioner will sink and increase the cooling effect.
The air conditioner should not be used for too long. Turning on the air conditioner for a long time will increase the load of the refrigeration system, which is not good for your health. You can turn it off first and then open it later. Don't sleep in a closed car with the air conditioner on. Due to poor ventilation in the car, carbon monoxide emitted by the engine may penetrate into the car, causing carbon monoxide poisoning.
