Starting BMW's parking ventilation system is an auxiliary function to prevent drivers from entering the vehicle in summer. When using this function, the vehicle will monitor the temperature inside the vehicle. When the warning value is reached, the air conditioner will ventilate the vehicle to reduce the temperature inside the vehicle.
The seat ventilation of BMW 5 Series is to add a fan on the foam back of the seat cushion and backrest, and use the fan to suck air into the ventilation layer, and then the air flow penetrates upward from the surface of the ventilation layer through the heating pad to the surface of the seat cover (the seat cover is made of perforated leather), so that passengers can use the ventilation function to disperse the sweat on their hips and back in hot weather, which brings comfort to passengers.
Bmw 5 series air conditioning system is mainly composed of air outlet device, special material for air permeable layer, patented anti-pressure air guide layer, wind power adjustment and wire assembly device. By connecting the air conditioning system of the original car, the front air guide device and the corresponding forced mute fan, cold air is pressurized into the seat sponge, and then through the air guide layer with the patented technology of front-end car modification, part of the pressurized cold air is directly blown to the leather surface through holes in the leather, and the other part is cooled in a large area inside the leather through the patented air guide layer. All technical details strictly test the actual combat experience of technicians.
In order to ensure the long-term tightness of passenger seat ventilation, BMW 5 Series is equipped with a patented air guide layer device in the seat ventilation system. It is one of the three main components of the whole ventilation system, and there are 250,000 experiments of extrusion without deformation, which is directly related to the comfort of the modified seat and the fullness of leather after long-term sitting, and ensures the uniform ventilation of the whole seat in a large area.
