Car air conditioner is relative to the car, and in itself is ?

A car air conditioner is (actuator) in relation to the car and (machine) in itself.

The engine is a whole of a car, composed of two major mechanisms of crank connecting rod mechanism and valve mechanism, composed of five major systems: starting system, ignition system, lubrication system, cooling system and supply system, therefore, forming an engine, the engine starts by fuel, there are gasoline, diesel, liquefied petroleum gas, natural gas, etc., all of which are mixed with air after entering the cylinder, and with the compression of the cylinder, the mixture is getting thicker and thicker, and then the spark plug ignition of the gasoline engine, or the compression ignition of the diesel engine, after ignition, When the piston is pressed down to the bottom dead center, the crankshaft rotates, the crankshaft drives the flywheel, and the flywheel passes through the transmission shaft to connect the clutch and the transmission, so that when the car starts, when the engine speed goes up, when you slowly lift the clutch, the transmission shaft drives the engine to rotate, so that the front axle differential lock also begins to rotate, and then drives the universal joint, and then drives the front axle, the transmission shaft of the left rear wheel rotates, and then makes the car drive away, in general, the engine is the heart of the car, Now in order to ensure that the wear and tear of the engine is small and the life is long, so when the parts are rubbed, it is a test, so each engine has an oil, oil filler, is in the oil pan, through the oil pump to the crankshaft, camshaft, valve, cylinder, so that the parts are lubricated, the cooling system, is the car through the start, the coolant, through the water pump to the cylinder wall, the cylinder is cooled, the cooled coolant flows to the water tank, and then cooled with air, and then flows to the cylinder wall, the starting system is the car by turning the key, The generator is energized, and then transmitted to the transformer, so that the electricity is pressurized, and then through the distributor, it is transmitted to the spark plugs of each cylinder, so that each cylinder starts to work, and the above is the power of the ordinary car I introduced to you.

Hello, the five major systems of air conditioning installation are: ventilation system, air cooling system, heating system, humidification system. Automatic control system, you can literally understand it.

Automobile air conditioning refers to the air conditioning device installed on the car, which can refrigerate, heat, ventilate and purify the air in the cabin, provide a comfortable riding environment for passengers, reduce the fatigue intensity of the driver, and improve driving safety. Air conditioning units have become one of the indicators to measure whether a car is fully functional.

Generally, it includes a refrigeration device, a heating device and a ventilation device, which makes full use of the limited space inside the car, has a simple structure and is easy to operate, and is an internationally popular modern automobile air conditioning system.

The role of car air conditioning is to cool or heat, air conditioning is a comfort configuration, and the car is equipped with air conditioning to increase the comfort during driving or riding. The heating principle of the car air conditioner is very simple, after turning on the heating function, the high-temperature coolant in the engine will flow through the warm air water tank, and the air blown by the blower will pass through the warm air tank, so that the air conditioning outlet can blow out the warm air. The refrigeration principle of the car air conditioner is also very simple, after pressing the AC button, the clutch of the air conditioner compressor will be combined, so that the engine will drive the compressor to rotate.

The compressor continuously compresses the refrigerant and delivers it to the evaporation tank. As the refrigerant grows larger in the evaporation chamber, it absorbs heat and cools the chamber. The cooled evaporation box can also cool the air blown by the blower, so that the air conditioning outlet can blow cold air.

Almost all cars will be equipped with air conditioning, which can improve the comfort of the car. Secondly, the function of automobile air conditioning is to keep the temperature, humidity, air cleanliness and air mobility in the cabin in a comfortable state, in various climatic and environmental conditions, the electric vehicle should be kept in a comfortable state to provide a comfortable driving and riding environment, especially in the hot summer, can greatly reduce their labor fatigue, reduce the occurrence of traffic accidents.

The purpose of a car air conditioner is to move the heat from the air inside the car with a lower temperature to the atmosphere with a higher temperature, so that the air inside the car is kept at a lower temperature. This is a reverse circulation of heat flow, which needs to be done with the help of a refrigeration mechanism. There are many ways to refrigerate, and compression refrigerants are mainly used for refrigeration in automobiles.

It is the effect of using liquid refrigerant to absorb heat in automobiles.

The refrigeration system is mainly composed of four assemblies: compressor, condenser, expansion valve and evaporator, and the high-temperature and high-pressure refrigerant from the compressor enters the condenser through the high-pressure hose. Since the outside temperature is lower than the temperature of the refrigerant entering the condenser, the action of the condensing fan is used. A large amount of heat from the refrigerant in the condenser is taken away by the outside air, so that the high-temperature and high-pressure gases are condensed into high-temperature, high-pressure liquids.

When this high-temperature and high-pressure liquid flows through the throttling expansion valve, due to the throttling effect, the volume suddenly increases and the pressure is reduced, and it becomes a low-temperature, low-pressure mist (liquid) that enters the evaporator and vaporizes at constant pressure.

Because the temperature of the refrigerant in the tube is lower than the circulating air in the car outside the evaporator tube, it can automatically absorb the heat in the air outside the tube, so that the air temperature flowing through the evaporator is reduced, and the effect of refrigeration and cooling is produced, and the vaporized refrigerant is sucked and compressed by the compressor to become a high-temperature and high-pressure gas, and is sent to the condenser through the high-pressure hose, so as to complete the thermal cycle of a refrigeration system.

Car air conditioners do not need to be turned on again after each shutdown like household air conditioners, in fact, car air conditioners should be turned on once a week even in winter to allow all parts to be lubricated. In addition, the dust filter should also be checked, and if too much dust is attached, it should be replaced in time. The condenser located at the front of the car is best washed with a high-pressure water gun every time the car is washed to prevent the heat dissipation blades from being blocked by debris (insects, leaves, etc.) and affecting the heat dissipation effect.

At present, most of the refrigerants used in cars (mainly referring to civilian cars) are R-12 refrigerant and R-134A refrigerant. R-12 refrigerant is an ordinary refrigerant that contains a substance that destroys the ozone layer - freon, and it will produce substances harmful to the human body under an open flame; R-134A is a new type of environmentally friendly refrigerant, which has the properties of non-toxic, colorless, non-flammable and non-explosive, good thermal stability, and more importantly, R-134A refrigerant does not damage the ozone layer.

The main function of the car air conditioner is to adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment in the best state, provide a comfortable riding environment for the occupants, and reduce the fatigue of the journey; Ventilation devices that create good working conditions for drivers and play an important role in ensuring safe driving.

Automotive air conditioning device (hereinafter referred to as automobile air conditioner). It is used to adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment in the best state, provide a comfortable riding environment for the occupants, and reduce the fatigue of the journey; Ventilation devices that create good working conditions for drivers and play an important role in ensuring safe driving. It generally includes refrigeration units, heating units and ventilation units.

This kind of combined device makes full use of the limited space inside the car, has a simple structure and is easy to operate, and is an internationally popular modern automobile air conditioning system.

Air conditioner is short for air conditioner. Automotive air conditioning is a branch in the field of air conditioning, which controls the temperature, humidity, cleanliness, and wind speed of the indoor air in the car in a certain way, and makes it flow and distribute in the car room at a certain speed, so as to provide a comfortable environment air treatment process for drivers and passengers, that is to say, the automotive air conditioning device should have a number of functions such as refrigeration, heating, ventilation, air purification, humidification and dehumidification.

In the automotive air conditioning system of air conditioning, the performance evaluation indicators of air conditioners are as follows, the air volume of air conditioners, as well as the wind pressure of air conditioners, and the cleanliness of indoor air, which are all performance indicators of affordable air conditioners.

The characteristics of car air conditioners are as follows:

1. Large refrigeration capacity and rapid cooling.

2. It is not convenient to use electricity as a power source, and the automobile engine or auxiliary engine must be used to drive the compressor, so it is much more difficult to deal with the power source than the room air conditioner.

3. The refrigerant flow rate in the system changes greatly (the air conditioning system driven by the engine changes the speed of the car greatly).

4. High condensation temperature. The ventilation and cooling effect of the condenser is affected by the radiant heat of the engine tank, the speed of the car and the dust pollution of the road surface.

5. The refrigerant is easy to leak.

6. Due to the compact structure of the car, the installation position of the refrigeration device is very limited, and various models must have special in-car air-conditioning equipment, and it is very difficult to generalize the evaporator assembly.

7. Due to the small height of the carriage, the air volume distribution is not easy to be uniform, so the temperature in the car is not easy to be uniform.

The heating of the automobile air conditioner is supplemented by the engine, and the rest is almost the same system and composition as the household air conditioner, with compressors, condensers, evaporators, and expansion valves.

In 1769, the Frenchman N.J. Günyu built a three-wheeled car powered by steam from the combustion of coal gas, but the speed of such a car was only 4 kilometers per hour, and it was very troublesome to stop every 15 minutes to refill the boiler with suntsa coal. Later, the car crashed into a brick wall during a march and shattered the collision. Such as spark point friend pants fire, water cooling cycle, steel tube frame, leaf spring suspension, rear-wheel drive, front-wheel steering and brake handlebars, etc.

On January 29, 1886, the German engineer Karl Benz filed a patent for his motor vehicle.
