Type of automotive air conditioning system
1. According to the driving method: independent (one dedicated engine-driven compressor, large cooling capacity, stable operation, but high cost, large volume and weight, mostly used for large and medium-sized passenger cars) and non-independent (air conditioning compressor) Driven by the car engine, the cooling performance is greatly affected by the engine work, and the stability is poor, and it is mostly used for small passenger cars and cars.
2, according to air conditioning performance is divided into: single function type (the refrigeration, heating, ventilation systems are installed separately, separate operation, do not interfere with each other, mostly used on large passenger cars and trucks) and integrated heating and cooling (cooling, heating, ventilation sharing) The blower and the air duct are controlled on the same control panel. When working, they can be divided into a combination of cold and warm air working separately and a mixed temperature regulating type in which the cold and warm air can work at the same time. The car is mixed with temperature and temperature.
According to the control mode, it is divided into manual type (the function key on the dial control board controls the temperature, wind speed and wind direction) and the electronically controlled pneumatic adjustment (using the vacuum control mechanism, when the air conditioner function key is selected, it can automatically be within the predetermined temperature. Control temperature and air volume).
3, according to the control mode is divided into: automatic adjustment (using the calculation comparison circuit, through the sensor signal and pre-adjustment signal control adjustment mechanism to work, automatically adjust the temperature and air volume) and the microcomputer-controlled automatic adjustment (with the microcomputer as the control center, to achieve Optimal control and adjustment of all-round, multi-functional air environment in the car).
