What is the composition of car air conditioning?

Automotive air conditioning is generally composed of a compressor, an electronic clutch, a condenser, an evaporator, an expansion valve, a liquid storage dryer, pipelines, a condensing fan, a vacuum solenoid valve, an idler, and a control system. Automotive air conditioning is divided into high-pressure pipelines and low-pressure pipelines, with the high-pressure side including the compressor output side, high-pressure pipeline, condenser, liquid storage dryer, and liquid pipeline; The low-pressure side includes the evaporator, accumulator, return air pipeline, compressor input side, and compressor oil tank.

In summer, there is a large temperature difference between the inside and outside of the car. When entering the car, it is not advisable to immediately turn on the air conditioning and set the temperature too low. You can first use a large amount of natural air to blow away the hot air in the car, and then do not close all the windows. Turn on the air conditioning, and after the body gradually adapts, adjust the air conditioning to the desired temperature and close the windows. This way, our bodies will not experience discomfort due to sudden drops in external temperature.

The temperature of air conditioning is not necessarily the lower the better. The most comfortable temperature for the human body is around 23 degrees Celsius. In the sunny afternoon of summer, air conditioning should not be too low. It can resist the hot summer sunshine and ensure that the environmental temperature of the human body is not too low, which can lead to "air conditioning disease". At the same time, it also responds to the national call for energy conservation, emission reduction, and low-carbon environmental protection.

When turning on the air conditioning, passengers are advised not to smoke inside the car. This is because when the air conditioning is turned on, the air inside the car circulates in a relatively closed environment. Firstly, smoke is not easily released, and secondly, small particles in the smoke will adhere to the air conditioning intake filter, causing a long-lasting odor inside the car.

Additional Information:

Modern car air conditioning has four functions, any of which is designed to make passengers feel comfortable.

（1）The air conditioner can control the temperature inside the cabin, both heating and cooling the air, in order to control the temperature inside the cabin to a comfortable level;

（2）The air conditioner can remove moisture from the air. Dry air absorbs human sweat to create a more comfortable environment;

（3）The air conditioner can draw in fresh air and has ventilation function;

（4）The air conditioner can filter the air and remove dust and pollen from the air.
