Solution introduction: Automobile air conditioning adjustment board

l Modern air conditioning system

It consists of refrigeration system, heating system, ventilation and air purification device and conditioning system.

Automobile air conditioner regulator is the regulating device of automobile air conditioning equipment. Adjust the car air conditioning system, with cooling, ventilation, defrosting functions. It is very important that all equipment is firmly installed, the adjustment device and operating mechanism are flexible and easy to operate, and the performance is safe and reliable.

The automotive air conditioning system is a device that cools, heats, ventilates and purifies the air in the car. It can provide passengers with a comfortable riding environment, reduce the driver's fatigue intensity, and improve safe driving. The air conditioning unit has become one of the symbols to measure whether the car is fully functional.

l Types of automotive air conditioning systems

1. According to the driving mode, it is divided into: independent type (special engine-driven compressor, large cooling capacity, stable operation, but high cost, large volume, heavy weight, mostly used in large and medium-sized passenger cars) and non-independent type (air conditioning compressor is driven by automobiles) Driven by the engine, the refrigeration performance is greatly affected by the engine, and the stability is poor, and it is mostly used in small passenger cars and cars).

2. According to the performance of the air conditioner, it is divided into: the first single-function type (refrigeration, heating, and ventilation systems are installed and operated separately, without interfering with each other. It is mostly used in large passenger cars and trucks) and integrated cooling and heating (cooling and heating ventilation share the blower and air duct, Good adjustment on the same regulating board. When working, it can include combined cooling and heating air working separately and mixed temperature adjustment type where cooling and heating air can work simultaneously. Multi-purpose vehicle with mixed temperature control).

3. According to the adjustment method, it is divided into: fully automatic adjustment (with the help of calculation equivalent circuit, the temperature and air volume are automatically adjusted by the sensor signal and pre-adjustment signal) and microcomputer automatic adjustment (with the microcomputer as the adjustment center, it can realize the full control of the air environment in the car. Orientation, multi-functional optimal adjustment and adjustment).

There are manual adjustment methods (the temperature, wind speed and wind direction can be adjusted by turning the function keys on the adjustment panel) and electropneumatic adjustment (with the help of the vacuum adjustment mechanism, when the air conditioning function key is selected, the temperature and air volume can be automatically adjusted within the predetermined temperature).

l Air conditioning system layout

Different types of air conditioning systems are arranged in different ways. Integrated air conditioning systems are widely used in cars today. Its layout is to assemble evaporator, warm air radiator, centrifugal blower, control mechanism and so on. That is the so-called air conditioning assembly.
