What are the components corresponding to the four basic working links of automotive air conditioning

The principle of automobile air conditioning refrigeration is the same as that of its 2113 other refrigeration device. The 5261 refrigerant working fluid is refrigerated in the evaporator in liquid 4102, and the cryogenic liquid absorbs the latent heat of vaporization 1653 into refrigerant gas and is sucked in and compressed by the compressor, and the pressure and temperature of the compressed gas are increased, and then flows into the condenser, and the condenser is air-cooled? Are all air cooled car air conditioners?

The snow condenses the refrigerant gas, and the condensed high-temperature and high-pressure liquid is stored at the bottom of the condenser and the reservoir, and the heat released during condensation is brought out by the fan and dispersed to the outside of the car.

The 4 major components of an air conditioner include: compressor, condenser, evaporator, and four-way valve.

Compressor: Extracts air from an evaporator to compress the refrigerant into high-temperature and high-pressure vapor and provides power to the entire refrigeration circuit.

Condenser: It cools the refrigerant vapor at high temperature and high pressure, and releases heat, and the condensation heat is carried away by the external air medium.

Throttling device: The pressure is adjusted by changing the size of the pipeline, so that the high-pressure refrigerant liquid becomes a low-pressure refrigerant liquid, and the liquid supply of the evaporator is adjusted at the same time.

Evaporator: The refrigerant vaporizes and absorbs heat in the air, and at the same time, the moisture in the air condenses into small water droplets, so as to achieve the effect of dehumidification and cooling and realize the refrigeration process.

The 4 basic components of an automobile air conditioner are compressor, condenser, expansion valve, and evaporator.

Such a question is easy to find on the Internet, so I won't go into details, search for "the principle of car air conditioning".

Air conditioning in cars.

The system is mainly composed of refrigeration system, heating system, air supply system, control system and air purification system.

The refrigeration system of automobile air conditioner is mainly composed of evaporator, air conditioning compressor, condenser, liquid storage tank, expansion valve and high and low pressure pipelines.

The heating system is mainly composed of a heating core, a water valve, a blower, etc.

Automotive air conditioners are generally mainly composed of air conditioning compressors, electronically controlled clutches, condensers, evaporators, expansion valves, receiver driers, hoses, condensing fans, vacuum solenoids, idlers and control systems.

The automotive air conditioning and refrigeration system is composed of compressors, condensers, liquid storage dryers, expansion valves, evaporators and other main components, as well as air conditioning pipelines and refrigerants.

Compressor - Driven by the engine, the low-temperature and low-pressure refrigerant vapor generated by endothermic vaporization in the evaporator is continuously sucked in, and the high-temperature and high-pressure refrigerant vapor is formed after compression, which is discharged to the condenser to create high-pressure conditions for the continuous condensation and exothermy of the refrigerant in the condenser. At the same time, the circulating flow resistance of the refrigerant in the refrigeration circuit is overcome.

Condenser - The heat contained in the high-temperature and high-pressure refrigerant steam discharged from the compressor is released to the outside air flowing through the condenser, and the refrigerant vapor is condensed into a refrigerant liquid with a certain degree of supercooling. The condenser is mostly arranged in front of the cooling water tank at the front of the car, which is cooled by the cooling fan and the windward airflow generated by the car's driving.

Reservoir Dryer – When the refrigeration system is in operation, the liquid refrigerant is filtered, dried and hygroscopic, and temporarily stored. A sight glass is often installed above it to observe whether the refrigerant is filled with sufficient and whether the flow is normal (the refrigerant should be foam-free and flow smoothly).

Expansion valve—throttles and lowers the pressure of the high-pressure refrigerant liquid from the reservoir dryer to form a low-temperature and low-pressure mist refrigerant, which is sprayed into the evaporator. The flow rate of refrigerant injected into the evaporator can be automatically adjusted according to the temperature of the outlet refrigerant steam of the evaporator.

Evaporator – The low-temperature and low-pressure refrigerant liquid continuously evaporates and vaporizes to absorb the heat flowing through the air of the evaporator and cool the air in the cabin. The evaporator is arranged in the car compartment and is usually supplied by a centrifugal fan.

Air conditioning piping – made of aluminum hard pipes and rubber hoses that connect the components of the refrigeration system.

Refrigerant - The vaporization of the refrigerant in the evaporator absorbs the heat of the air in the cabin to achieve refrigeration, and the condensation in the condenser releases heat to the air outside the vehicle.

The automotive air conditioning system is mainly composed of the following components: automotive air conditioning compressor, condenser, throttle expansion structure, evaporator, and pipeline. Automotive Air Conditioning Compressor:

It is the heart of the automotive refrigeration system and the power source that promotes the continuous circulation of refrigerants in the refrigeration system. Exhaust pipeline: connecting line between compressor and condenser, high-pressure pipe.

The refrigerant flows from the compressor to the condenser. Condenser: A heat exchange equipment that discharges the high-temperature and high-pressure superheated refrigerant vapor discharged from the compressor and releases heat to the air outside the condenser through the metal wall tube and/or fins, so that the superheated gaseous refrigerant is condensed into a high-temperature and high-pressure liquid.

Inlet pipe: condenser and throttle expansion mechanism connecting pipeline, high-pressure pipe. The refrigerant flows from the condenser to the throttle expansion mechanism.

Throttle expansion structure: It plays the role of throttling and depressurizing in the whole system, and is the dividing component of high pressure and low pressure in the whole system. Evaporator:

It is a low-temperature and low-pressure liquid refrigerant throttled by throttling expansion structure, in which endothermic vaporization achieves refrigeration effect. Suction line: The connecting line between the evaporator and the compressor.

The refrigerant flows from the evaporator to the compressor.

Automobile air conditioners are generally composed of compressors, condensers, evaporators, expansion valves, liquid storage dryers, pipelines, systems, etc. The automobile air conditioning system is a device that realizes cooling, heating, ventilation and air purification of the air in the cabin. It can 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.

Compressor: The compressor is the "heart" of the air conditioning and refrigeration system, and it is a power source that circulates the refrigerant in the system. Its function is to compress the gaseous refrigerant that is inhaled at low temperature and low pressure into a high temperature and high pressure refrigerant, which is the process of completing the transformation of the refrigerant from gaseous to liquid state.

Condenser: The function of the condenser is to cool the high-temperature and high-pressure cooler steam discharged from the compressor to condense it into a high-pressure refrigerant liquid, and then send it to the reservoir dryer. There are three main types of condensers, which are segmental, tubular belt, and fin.

Reservoir dryer: Reservoir dryer can literally be seen that it has both a reservoir and a drying function. Its function is to replenish the refrigerant for the excess space of leaking refrigerant, and at the same time play the role of filtration, filtering out impurities and moisture in the refrigerant.

Expansion valve: Expansion valve, also known as throttle valve, is the main component of the automobile air conditioning and refrigeration system, and is the dividing point between high and low pressure of the automobile air conditioning and refrigeration system. Its function is to throttle and decompress the high-pressure liquid refrigerant from the reservoir dryer, regulate and control the liquid refrigeration dose entering the evaporator, so that it can adapt to the change of refrigeration load, and at the same time can prevent the liquid shock phenomenon of the compressor (that is, the unevaporated liquid refrigerant is compressed after entering the compressor, which is easy to cause damage to the compressor valve) and the vapor at the outlet of the evaporator is abnormally overheated.

Evaporator: The liquid refrigerant with low temperature and low pressure absorbs the heat of the air around it through the evaporator and boils and vaporizes it, so that the surface and air temperature of the evaporator are reduced, and then cooled by the evaporator and turned into cold air and sent to the car for cooling.

The automotive air conditioning system consists of five subsystems: refrigeration system, heating system, air distribution and ventilation system, control system, and air purification system.

1. Refrigeration system.

Function: Cools and dehumidifies the air inside the car and the fresh air entering the car from the outside, so that the air inside the car becomes cool and comfortable.

4. Control system.

Function: Control the temperature and pressure of the air conditioning and refrigeration system and heating system, and control the temperature and wind speed of the air in the car to meet the driver's needs for the environment in the car.

Composition: It mainly refers to the control panel and control circuit.

5. Air purification system.

Function: Remove dust, odor and other toxic gases in the air, make the air clean and clean, and contribute to the physical and mental health of drivers.

Composition: Filtration and dust removal is composed of non-woven fabric, dry fiber filter, and metal mesh immersion filter. Electrostatic precipitator is composed of a primary filter, a precipitator, a charging electrode, an ionizer, a blower, an activated carbon filter, and so on.

A modern air conditioning system consists of a refrigeration system, a heating system, a ventilation and air purification device, and a control system. Automotive air conditioners are generally composed of compressors, electronically controlled clutches, condensers, evaporators, expansion valves, liquid storage dryers, pipelines, condensing fans, vacuum solenoid valves), idlers and control systems.

The automobile air conditioning system is mainly composed of five parts, namely refrigeration system, heating system, ventilation system, purification system, and control system.

Automobile air conditioning and refrigeration generally have compressors, condensers, drying bottles, expansion valves, evaporation tanks, high and low pressure pipelines, as well as pressure switches and air conditioning control panels.

Resurrection piston compressor.

Then the type of compressor can be assigned according to its structure, first of all, the reciprocating piston type. So this kind of structure is the most common model now, and it has very rich experience in technology and production. And the requirements for materials will be relatively low, the cost is relatively low, if the driver's car performance is poor.

And if it is not so high, you can choose such a compressor to match your car.

Generally, it is composed of evaporation tank, compressor, condenser, liquid storage and drying tank, expansion valve, high and low pressure pipelines, etc.

Compressors, condensers, pressure switches, expansion valves, evaporators, pipelines, evaporator temperature sensors, indoor and outdoor temperature sensors, sunlight intensity sensors.

First of all, the self-cooling system is responsible for the cooling part of the air conditioner. Among them, the main parts are: refrigeration compressor.

The negative compressor compresses the air into a high-temperature and high-pressure gas. Then, a condenser is needed, and the gas passes through the throttling element to transfer the high-temperature and high-pressure gas to the condenser, which condenses the gas into a liquid. Among them, the participation of capillaries is also required.

2. Air path system. It is a system of internal exchange of air conditioners, which can facilitate the conversion of hot air in the space. It is mainly composed of centrifugal fans and axial fans.

3. Electrical system. The computer-controlled air conditioning system is set manually and operated automatically by computer control, including the operation of the compressor, the opening of the heater water valve, the opening angle of the mixing damper, and the selection of the wind speed of the blower. Fully automatic air conditioners, all self-air conditioners are generally controlled by buttons, and the operating system is generally electro-pneumatic.

4. The next is the box and panel, which is the outer packaging of the air conditioner, which is the same as the clothes. It also has its own functions, such as the frame of the air conditioner, the support of each system, and the guidance of the airflow. The main components are the cabinet, panel, and louver grille.

5. Fan system. It can inhale fresh air and act as a ventilator, and in the process of convection with the outside air, the air conditioning filter in the car air conditioning system can filter the air, and can filter the dust and pollen and other items in the air, so that the air in the car can be kept clean and fresh.
