car air conditioningWhat is the main component of the control system?

1. The composition of the automobile air conditioning control system. The automobile air conditioning control system includes power supply control circuit, compressor clutch control circuit, safety protection control circuit, data communication circuit, etc.

2. The air conditioning system of a car is mainly composed of five parts: refrigeration system, warm air system, ventilation system, air purification system and control system. Refrigeration system: Cool or dehumidify the air in the car or the fresh air entering the car from the outside, so that the air in the car becomes cool and comfortable.

3. Refrigerant is an important part of the car air conditioning system. Its function is to circulate between the compressor and the evaporator to discharge heat from the car. Common refrigerants include R-134a and R-12, etc. In summaryDescription: The automobile air conditioning system is mainly composed of compressor, condenser, evaporator, expansion valve and refrigerant and other parts.

4. The air conditioning system is generally composed of the following components: Compressor: The compressor is the most important part of the air conditioning system. It compresses it into high-temperature and high-pressure gas by compressing the refrigerant, and then sends it to the condenser for cooling.

5. Car air conditioners are composed of refrigeration system, heating system, ventilation and air purification device and control system. Nowadays, cars mainly make full use of the residual heat of the coolant after the engine is cooled for heating, which is often called water cooling.

6. The automobile air conditioning system is mainly composed of the following parts: refrigeration system: The function of the compressor is to compress low-pressure steam into high-pressure steam, which reduces the volume of steam and increases the pressure.The compressor sucks out low-pressure steam from the evaporator and sends it into the condenser when the pressure rises.

What are the ways of air conditioning control on the car?

1. If car air conditioners are classified according to the control method, there are currently three types of manual air conditioners, semi-automatic air conditioners and automatic air conditioners.According to the power source, it can be divided into independent air conditioners and non-stand air conditioners, among which free air conditioners are generally used in buses or long-distance freight buses.

2. There are three control methods. The first is completely manual operation, the second is automatic air conditioning, the third is voice control air conditioning, and the fourth is remote operation of the mobile phone app.

3. Car air conditioners can be divided into independent air conditioners and non-start-alone air conditioners according to the driving mode. Stand-alone air conditioners are equipped with a special auxiliary engine as the power source of the compressor (such as bus air conditioners), and non-independent air conditioners are directly driven by the main engine of the car (such as cars, minibuses and truck air conditioners, etc.).

4. Generally including refrigeration device, heating device and ventilationDevice, this joint device makes full use of the limited space inside the car. The structure is simple and easy to operate. It is a modern car air conditioning system that is popular in the world.

5. How to use a car air conditioner is in the case of automatic air conditioning, directly press the auto button on the air conditioner panel, and the car air conditioner will start. Then, adjust the temperature, and the air conditioning system can automatically adjust the air volume.

What is the main role of the electronic control system of automobile air conditioning?

1. As an important component of car comfort, the control circuit of car air conditioner is the key to the work of the system.

2. It has the functions of refrigeration, heating, defrosting and defogging and ventilation; it is composed of air conditioning box, air conditioning pipeline, electric compressor, condenser, air conditioning control panel and related sensors.

3. The function of the air conditioning system control circuit is to control the switch of the air conditioning system according to the external temperature or the temperature of the evaporator, so as to control the temperature in the car. The function of the car air conditioner dryer is to absorb the moisture that may be contained in the air conditioning system.

4. Keep the air in the car clean. Control system: The control system is mainly composed of electrical components, vacuum pipes and control mechanisms. On the one hand, its function is to control the temperature and pressure of the refrigeration and warm air system, and on the other hand, it is to manipulate the temperature, air volume and flow direction of the indoor air in the car to improve the functions of the air conditioning system.
