The blower motor is the source of the cold and hot air at the air outlet of the air conditioner. Without a blower, the air conditioner can also cool or heat. It is only in the interior that it needs to be blown out by the blower to achieve the cooling or heating effect.
The role of car air-conditioning blower and air-conditioning system: the role of the air-conditioning system in the car
- The air-conditioning grid can be closely attached to the shell to ensure that unfiltered air will not enter the compartment;
- It can separate solid impurities such as dust and abrasive particles in the air;
- It can adsorb soot, peculiar smell, SO₂, CO₂ and other harmful gases in the air;
- It can absorb the water in the car, so that the car glass will not be covered with water vapor, so that the driver’s vision is clear, and the driving is safe;
- It can effectively sterilize and deodorize, ensure that the air in the car is clean and does not breed bacteria, and create a healthy environment;
- It can effectively intercept pollen and ensure that drivers and passengers will not have allergic reactions and affect driving safety.
The role of car air-conditioning blower and air-conditioning system: the difference between car blower and air-conditioning
Turn on the blower (air switch of the air conditioner), if the temperature is the lowest temperature, then:
The temperature of the natural wind outside the car is the temperature of the external circulation, but it will be slightly higher because the air inlet of the external circulation of the air conditioner is basically between the lower edge of the front windshield and the engine compartment, which will bring the temperature into the engine room;
If it is an internal cycle, the temperature inside the car will be blown out.
If the temperature is selected to be higher, the engine’s cooling water heat passes through the evaporator (small water tank radiator) in the air conditioning system, and the temperature of the wind is adjusted by the hot air through the opening angle of the partition with the natural wind;
Turn on the air conditioner (A/C) switch. If it is an automatic air conditioner, the blower will automatically start the air supply; if it is manually switched on, the air conditioner compressor will usually start to work after the blower is turned on.
