What are the functions of the blower and the air conditioning system in an automobile air conditioner?

The function of an air conditioning blower

The blower serves as the source of cold and hot air at the air conditioning outlet. Without the blower, the air conditioner can still cool or heat, but only internally. The blower is necessary to blow out the air for cooling or heating effects.

The function of the blower and air conditioning system in automobile air conditioning: the function of the air conditioning system inside the car

The function of the air conditioning system in a car

1. It can make the air conditioning filter tightly adhere to the shell, ensuring that unfiltered air does not enter the cabin;

2. Capable of separating solid impurities such as dust and abrasive particles in the air;

3. Capable of adsorbing harmful gases such as soot, odor, SO₂, and CO₂ in the air;

4. It can adsorb moisture inside the car, preventing water vapor from forming on the car windows, thus ensuring clear vision for the driver and passengers and enhancing driving safety;

5. It can effectively sterilize and deodorize, ensuring clean air inside the car without breeding bacteria, creating a healthy environment;

6. It can effectively intercept pollen, ensuring that the driver and passengers will not experience allergic reactions that could affect driving safety.

The role of the car air conditioning blower and air conditioning system: the difference between the car blower and air conditioning

Turn on the blower (the air-blowing switch of the air conditioner). If the temperature setting is at the lowest level, then:

The difference between a car blower and an air conditioner

The temperature of the natural wind outside the car is slightly higher in the external circulation mode, as the air intake of the external circulation mode of the air conditioner is basically located between the lower edge of the front windshield and the engine compartment, which will bring in the temperature of the engine compartment;

If it is an internal circulation, the temperature blown out is the temperature inside the car.

If the temperature is set to be high, the heat from the engine's cooling water passes through the evaporator (a small radiator) in the air conditioning system, and the temperature of the hot air is adjusted by adjusting the opening angle of the partition that separates it from the natural wind;

Turn on the air conditioning (A/C) switch. If it is an automatic air conditioning system, the blower will automatically start to blow air; if it is a manual switch, the air conditioning compressor will usually start to work only after the blower is turned on;

When the A/C compressor is activated, the air blown out through the condenser in the air conditioning system is cold. However, the temperature can also be adjusted by controlling the mixing ratio of natural air, hot air from the evaporator, and cold air from the condenser through the baffle in the system, to meet the temperature requirements;
