Summer, summer, and there are car owners who drove their car we can go to the beach sun sun bath, you can go to the mountain’s summit, you can go to a strange city to risk not feel the same customs. And these are in our air-conditioned car so that the case, otherwise our car is a “Move the oven.”
Automotive air conditioning system is the air in the cooling, heating, ventilation and air purification devices. It can provide for the ride comfortable traveling environment, reducing operator fatigue. Most passenger cars from the engine-driven air-conditioning systems, and are equipped with heating and cooling functions.
Car air conditioning divided by manual control mode and automatic adjustment. Manual air conditioning control panel toggle function keys on the temperature, wind speed and direction control. Automatic air conditioning with vacuum control mechanism and electronic actuators, for setting a good amount of wind, temperature, wind direction and control. But both for cooling and heating air core substantially the same components. Air conditioning is typically dominated by the compressor (compressor), electrically controlled clutch, a condenser (condenser), an evaporator (evaporator), the expansion valve (expansion valve), Drier (receiver drier), pipes (hoses), condenser fan, vacuum electromagnetic valve (vacuum solenoid), idle and control system components. Automotive air conditioning and low pressure pipeline of high pressure piping. Including the output side of the high pressure side compressor, high pressure piping, condenser, dry and liquid line; low side including evaporators, accumulators, way back to the trachea, the input side of the compressor and compressor oil pools.
Drier – actually a refrigerant and absorbing the refrigerant storage of water, impurities of the device. On the one hand, it is equivalent to the car’s fuel tank, the refrigerant leak out of the space more add refrigerant. On the other hand, it is also like that the air filter, filter out impurities doped in the refrigerant. Drier also with a silicone material, play a role in absorbing water. The condenser and the evaporator – although they are not the same name, but the structure is similar. They are similar to a honeycomb aluminum casing tank, in order to achieve the outside air and the heat exchange pipe material of the device. Condenser means is its condensation heat from the refrigerant pipe cemented liquid from the gas. The principle is similar to the engine radiator (only difference is that the water tank has a liquid only), so it is often installed in the front, along with tanks, the use of this design is conducive to the front of the airflow for cooling. Evaporator and condenser on the contrary, it is a refrigerant from liquid into gas (i.e. Evaporation) absorbs heat the place.Here, I will introduce 2 kinds of auto diagnostic tools ,vag k can and bmw inpa , can make help .
