How many years does the general car air conditioning compressor last?

In the case of a car that is not a wearing part, the warranty period is usually three years and 60,000 km.

Compressors for automotive air conditioners.

It is the heart of the automotive air conditioning and refrigeration system, playing the role of compressing and transporting refrigerant.

The role of steam. There are two types of compressors: variable displacement and variable displacement. According to the different working principles, air conditioning compressors can be divided into fixed displacement compressors and variable displacement compressors.

Constant displacement compressors.

The displacement of the constant displacement compressor is proportional to the increase of the engine speed, it can not automatically change the power output according to the demand of refrigeration, and the impact on the engine fuel consumption is relatively large.

Although there are many types of vehicles, the structure is similar. This should be said to be the credit of standardization, but also the need for large-scale production lines. With the development of society, the progress of science and technology and the change of demand, the shape of railway vehicles has begun to change, especially the passenger car is no longer the same old face.

However, their basic structure has not changed significantly, but the specific parts have a more scientific and advanced structural design.

Generally speaking, the basic structure of the vehicle is composed of five parts: the car body, the undercarriage, the running part, the coupler buffer device and the braking device.

The body is the part of the vehicle that is used to load goods or passengers, and is the basis for the installation and connection of other components of the vehicle. The body of the early vehicles was mainly made of wood, supplemented by steel plates, bow rods, etc. In modern times, the car body is mainly steel structure or light metal structure.

Under normal circumstances, the compressor should be guaranteed for more than 5 years, so that it is normal and within a reasonable range.

The life of automobile air conditioning compressors is generally about 10 years, and how often to replace them depends on the quality of the compressor and the number of uses. After all, the quality of the compressor of each car is different, and the frequency of use of air conditioning compressors is different in different climate regions and different people.

Like the air conditioner of the general car air compressor, the compressor can basically be guaranteed for one year, and he has no problem within one year, and will help you with the warranty, which is still better.

There is no mandatory warranty policy in the country for automotive air conditioning compressors, and generally requires a warranty of at least one year. However, many car manufacturers will warrant compressors for two years or more. What is written in the vehicle maintenance manual, it is best to look at the maintenance manual.

When buying a brand of car, the warranty time is different, generally speaking, the warranty for air conditioning compressors is about three years.

The air-conditioning compressor of a normal car is guaranteed for three years, and if there is a problem within three years, it can be guaranteed.

This kind of is generally up to one year, and the main guarantee is the engine gearbox.

In addition to the three major parts, other wearing parts include: steering machine, turbocharger, air conditioning compressor, generator, gasoline pump, cooling fan, air conditioning blower, shock absorber, etc., after the warranty period, the maintenance of these parts is a burden for consumers.

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.

Automobile air conditioning compressor is guaranteed for a few years, I think the air conditioning compressor must be reported within ten years, I think it should be insured for a long time, some.

The warranty period of the air conditioning pump for general family vehicles is three years.

Generally, the compressor of automobile air conditioning is guaranteed for three years after a few years.

The general automobile air conditioning compressor is generally guaranteed for three years, or 100,000 kilometers.

The warranty of the automobile air conditioner is consistent with the warranty period of the whole vehicle, that is, two years or 60,000 kilometers, whichever comes first.

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.

The functions of modern car air conditioners are all designed to make passengers feel comfortable.

Types of car air conditioners.

1. According to the driving mode, it is divided into: independent (a dedicated engine-driven compressor, with large refrigeration capacity and stable operation, but high cost, large volume and weight, mostly used for large and medium-sized buses) and non-independent (air conditioning compressor is driven by the automobile engine, and the refrigeration performance is greatly affected by the engine work).

2. According to the performance of air conditioning, it can be divided into: single-function type (the refrigeration, heating and ventilation systems are installed separately and operated separately, without interfering with each other, and are mostly used in large buses and trucks) and integrated cooling and heating (refrigeration, heating and ventilation share blowers and air ducts, which are controlled on the same control panel).

The warranty of the automobile air conditioner is consistent with the warranty period of the whole vehicle.

Now most car manufacturers are implementing a new vehicle warranty period, "two years or 60,000 kilometers, whichever comes first." That is, there are two conditions during the warranty period, one is the time limit, the driving time is 2 years; The second is the mileage limit, which is 60,000 kilometers driven. As long as one of these two conditions is met, it means that the warranty period of the vehicle has expired, and the normal repair and maintenance of the vehicle is not free of charge.

If nothing is specified. It's the time of the whole vehicle warranty

Valid for 3 years.

Air conditioners belong to the "three guarantees" commodities stipulated by the state, and the "three guarantees" of the whole machine are valid for one year, and the main components (including compressors, fan motors, and thermostats) are valid for three years. The warranty period of the air-conditioning compressor issued by the manufacturer is generally higher than the national regulations, and the warranty period of the air-conditioning compressor issued by the manufacturer shall prevail, but the manufacturer's regulations have to be lower than the national regulations.

The working circuit of the air conditioning compressor is divided into evaporation zone (low pressure area) and condensation zone (high pressure area). The indoor unit and outdoor unit of the air conditioner belong to the low-voltage or high-pressure area respectively (depending on the working status).

The refrigerant then flows from the high-pressure area to the low-pressure area, and is injected into the evaporator through the capillary, and the pressure drops sharply, and the liquid refrigerant immediately becomes gaseous, absorbing a large amount of heat in the air through the heat sink. In this way, the air conditioning compressor works continuously, and constantly absorbs the heat at one end of the low-pressure area into the refrigerant, and then sends it to the high-pressure area to dissipate into the air, which plays a role in regulating the air temperature.

It's easy to break, but not necessarily. These electrical appliances must be used frequently to be able to use normally for a long time, but if they are not used for a long time, it is easy to fail to start normally.

Under normal circumstances, it will not be damaged, because the compressor motor is sealed in the iron tank and is isolated from the outside world.

As long as the protection is good, it will not be bad if you do not use the air conditioner for several years. It is necessary to do a good job of rainproof and dustproof work of the compressor.

The most common fault of the compressor is the cylinder, that is, the piston is stuck in the cylinder and cannot move, the phenomenon is that the current is very large, the thermal protector will soon jump, and the compressor does not run. Half an hour after pulling the plug, there is only a "buzzing" sound when the machine is turned on, and soon there will be a snapping sound, and the compressor will not be "buzzing".

The most common failure of a compressor is a clogged cylinder, i.e. the piston is stuck in the cylinder and cannot move. The phenomenon is that the current is very high, the thermal protector will soon trip, and the compressor will not work. Half an hour after unplugging, there is only a "buzzing" sound, which will soon make a crackling sound, and the compressor will not make a "buzzing" sound.

Under what circumstances will the compressor break the air conditioner The most common fault of the compressor is the cylinder, that is, the piston is stuck in the cylinder and cannot move, the phenomenon is that the current is very large, the thermal protector will soon jump, and the compressor does not run. Half an hour after pulling the plug, there is only a "buzzing" sound when the machine is turned on, and soon there will be a snapping sound, and the compressor will not be "buzzing".

The answer is not what you asked, it's almost the same as not saying it.

As a common household appliance, air conditioners are also subject to the provisions of the national three-guarantee law. The current regulation is that the internal and external aircraft are repaired for 6 years.

The whole machine is 3 years, and the compressor is repaired for 5 years. During the warranty period, if there are more than three repairs, which are not repaired and need to be repaired for the fourth time, the manufacturer can be asked to replace the machine. Generally, the warranty period of large brands of air conditioners will be appropriately extended on this basis.

However, one of the following cases does not fall within the scope of the warranty:

1. Damage caused by improper use, maintenance and storage of consumers;

2. Caused by installation and maintenance at non-designated special installation and maintenance points (including installation or dismantling and repair by consumers);

3. There is no warranty certificate and valid invoice or purchase certificate;

4. The valid certificate and the warranty certificate are inconsistent or altered;

5. Damage caused by irresistible natural disasters;

6. Products whose processed products have exceeded the warranty period. Refer to the service manuals of the major air conditioners.
