How much is the price of the air conditioning compressor for the German opel Astra 1 8 car

Hello. To about 1800 [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

The general non-original automobile compressor costs 900-1000 yuan. The original (imported) is more than 3000.

The automotive air conditioning compressor is the heart of the automotive air conditioning and refrigeration system, which plays the role of compressing and transporting refrigerant vapor. There are two types of compressors: immutable displacement and variable displacement.

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. Its control is generally by collecting the temperature signal of the air outlet of the evaporator, when the temperature reaches the set temperature, the compressor electromagnetic clutch is released, and the compressor stops working. When the temperature rises, the electromagnetic clutch engages and the compressor starts working.

Constant displacement compressors are also controlled by the pressure of the air conditioning system, and when the pressure in the pipeline is too high, the compressor stops working.

Variable displacement air conditioning compressor.

The variable displacement compressor can automatically adjust the power output according to the set temperature. The air conditioning control system does not collect the temperature signal of the air outlet of the evaporator, but automatically adjusts the temperature of the air outlet according to the compression ratio of the compressor according to the change signal of the pressure in the air conditioning pipeline. In the whole process of refrigeration, the compressor is always working, and the adjustment of refrigeration intensity is completely controlled by the pressure regulating valve installed inside the compressor.

When the pressure at the high-pressure end of the air conditioning line is too high, the pressure regulating valve shortens the piston stroke in the compressor to reduce the compression ratio, which reduces the refrigeration intensity. When the pressure at the high-pressure end drops to a certain level and the pressure at the low-pressure end rises to a certain level, the pressure regulating valve increases the piston stroke to increase the refrigeration intensity.

Well, I haven't heard of this brand, it's best to buy some big brands of air conditioners, like Gree, the quality and after-sales are ***.

At idling, the high pressure is about; Low pressure about.

The refrigerant used in automobiles today is generally R134A.

When the idle engine is fluorinated at 800rpm, the high pressure is about; Low pressure about.

When you step on the accelerator to speed up the engine to 1500rpm, the high pressure is about; Low pressure about.

According to the comparison of the two speeds, the amount of fluoride added is considered normal.

Advantages:win8 system no jamming phenomenon has not been tested in the game but the cost performance is higher 5000 to start with is still very worthwhile。

Disadvantages:Is there a disadvantage There are only a few power buttons when you boot up the feedback is not very good Second, it is slower to boot and when you boot up, there will be a black screen for a period of time Third, the hard disk is not very good When the hard disk is read, there will be a rattle rattle I think there should be a bad sector I don't know if other people have this phenomenon.

Summary: If you are not very picky about these little faults , and you are still a game lover If you are not very wealthy in hand, I think this computer is the only option on the market right now.

I just came back from a car dealer today! Now if you want to buy it, you can only import it in parallel, and Opel Yate ** low allocation to Hong Kong** 350,000 + 20,000 service fee! OPC top configuration**480,000 + 20,000 service fee, Yate convertible**580,000 + 20,000 service fee** These ** should be negotiable, I just asked casually without a counteroffer!
