What Is The AC System in A Car?

An automobile air conditioner consists of four parts: a heating device, cooling device, ventilation, air purification device, and control device. The relevant functions of the components of the automobile air conditioner are as follows: 1. Air conditioner heater. Raise the temperature inside the car and defrost the windshield. 2. Air-conditioning refrigeration device. Reduce the temperature and humidity in the car. 3. Air conditioning ventilation and air purification devices. Adjust the airflow and ventilation in the car, and filter the air entering the car. 4. Air conditioning control device. Control the work of the air conditioning system to realize heating, cooling, and ventilation.

Automobile air conditioners can be divided into the following different types, namely:

1. According to the driving mode, is divided into the independent type and non-independent type.

2. According to the performance of the air conditioner, it is divided into single-function types and integrated heating and cooling.

3. According to the control mode, can be divided into the manual type and electric control pneumatic adjustment.

4. According to the control method, is divided into automatic adjustment and automatic adjustment controlled by a microcomputer.

How Does Car Air Conditioning Work?

The operation of the automotive air conditioning system mainly relies on different types of air conditioning compressors, condensers, expansion tubes, receivers, and evaporators to work.

1. Compression: the different A/C compressor types suck in low-temperature and low-pressure refrigerant from the outlet of the evaporator, and after being compressed, it becomes high-temperature and high-pressure gas, which is discharged from the compressor and reaches the condenser through the pipeline.
2. Heat dissipation: the high-temperature and high-pressure refrigerant coming out of the compressor The refrigerant gas enters the condenser, the refrigerant gas condenses into liquid and discharges a large amount of heat, and dissipates heat through the condenser.
3. Throttling: the volume of the refrigerant liquid becomes larger after passing through the expansion valve, while the pressure and temperature drop sharply, becoming The mist that is discharged from the expansion device, and then flows into the evaporator in the car.
4. Heat absorption: the mist refrigerant liquid enters the evaporator and evaporates at a high temperature, and evaporates from liquid to gas. During the evaporation process, it will absorb a lot of surrounding heat.

How often should A/C system check?

Automobile air conditioners are generally maintained once a year, and the Air conditioning parts are fully cleaned. If the environment where the car is usually used is very harsh, and it is often necessary to drive the vehicle in a place with a lot of wind and sand, then the maintenance time of the air conditioner needs to be shortened. If the air conditioner is rarely turned on during the use of the car, the maintenance cycle of the air conditioner can be extended appropriately.

1. Check whether there is an oil stain between the hose and the pipe joint of the air conditioning system. If there is an oil leakage, it needs to be repaired in time.
2. The car air conditioner filter element needs to be cleaned regularly, especially in hot summer, as the number of times the air conditioner is used will increase. If the air conditioner filter element is not cleaned regularly, it is easy to breed bacteria, which will affect the health of the people in the car.
3. Do not turn on or off the air conditioner frequently, otherwise, it will easily cause damage to the air conditioner system.
