Product description
The function of the air outlet pipe of the car: When the car is running normally, fresh air enters from the air inlet continuously, and the dirty air in the car flows out from the air outlet, thus forming a good air circulation and ensuring the air in the car. Fresh, if you turn on the blower, it will speed up the flow of air in the compartment, and you can adjust the temperature in the compartment through the cooling and heating devices of the air conditioning system.
The so-called car ventilation system refers to the device that can circulate the air in the car compartment. Its function is to introduce fresh air outside the car into the car, and at the same time discharge the dirty air inside the car.
The ventilation system on the car generally has three ways, namely natural ventilation, forced ventilation and comprehensive ventilation.
The so-called natural ventilation refers to using the pressure difference inside and outside the car cabin to circulate the air inside and outside the car. For example, opening the glass or the sunroof is the simplest natural ventilation. When the car doors and windows are fully closed, the car can still feel cool. The breeze is also a credit to natural ventilation; forced ventilation refers to the use of air-conditioning blowers to force fresh air outside the car into the compartment, and finally achieves ventilation; comprehensive ventilation refers to the simultaneous use of natural ventilation and forced ventilation on the car. Generally, cars use comprehensive ventilation in normal driving.
Since it is "ventilation", there must be air inlets and outlets. Generally, the air inlet of the car compartment is designed in the upper right corner of the engine compartment and the lower right corner of the front windshield, which is what we know as the "air conditioning air inlet".
After the air enters from here, it enters the compartment from the air outlet on the instrument panel through the air-conditioning air distribution duct. This position is the positive pressure area of the car, which can ensure that enough air enters the car. At the same time, this position is relatively high, and there are relatively few pollutants such as car exhaust gas, dust, and muddy water. Most of the pollutants are kept out of the car, which is enough to ensure the quality of the air entering the car. In addition, there is an internal and external circulation flap at this position, which can control the amount of air entering the compartment.
But if the air in the car can only go in and out, it will inevitably cause the pressure in the car to be too high, which will make it difficult for fresh air to enter, and the quality of ventilation will be poor. increase. This requires that the compartment must be provided with an air outlet.
