The low pressure pipe of the car air conditioner is not cool, and the high pressure pipe of the car

Check whether the pipeline is blocked, before the arrival of summer, the air conditioning of the maintenance car is generally cleaned from the air conditioning grid, ventilation pipeline, evaporation box, compressor of the air conditioner, it is recommended that the owner can go to the professional maintenance car store to clean, the effect is better, if you want to clean yourself, you can inject the air conditioning cleaner from the tuyere, through the internal circulation of the air conditioner, to the surface of each component, the attached dust, bacteria, microorganisms are removed, and discharged out of the car through the air conditioning drainage pipe. The maintenance of the air conditioner of the car sometimes directly determines its use effect and life, so we must pay attention to the in-depth maintenance of the air conditioner.

Hello, this should be the fault of the refrigeration system, you can check it, it may be caused by insufficient refrigerant, or the pipeline is blocked.

This situation may be caused by a lack of refrigerant in the air conditioner. It is recommended to add fluoride to the air conditioner to try the effect of the vehicle air conditioner.

Hello, in this case, it is recommended to first check whether the refrigerant is missing, and then check whether the refrigeration pipeline is blocked?

Hello, if the low-pressure pipeline of the car air conditioner is bad, it means that the air conditioning refrigeration system is faulty, this first needs to see whether the compressor is normal, and then touch the high-pressure pipe to see if it is hot, if the high-pressure pipe is not hot, the compressor is rotating, it must be insufficient refrigerant.

Hello, in this case, it is recommended to first check whether it is missing, and then check whether the refrigeration pipeline is blocked?

The reason why the low-pressure pipe of the car air conditioner is not cool is that the air conditioner refrigerant is insufficientThe air conditioner pressure is not enough or there is a leak in the refrigerant line. Check whether there is any leakage in the air conditioning pipe, if there is a leakage point, it needs to be filled, and then re-vacuumed before adding refrigerant.

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 following points need to be checked when the air conditioner is not cooling:

1. Whether there is a refrigerant in the system, if not, it needs to be pressurized to check the leakage, and then add enough.

2. If there is refrigerant, check whether the compressor is working. If it is not working, you need to check whether there is any problem with the air conditioner pressure switch, temperature control switch and its wiring.

3. Check the heat dissipation of the air conditioner to see if the fan is working. Clean the condenser.

4. Replace the air conditioner filter, the filter element is too dirty, and it will also cause no refrigeration.

Hello, if the low-pressure pipeline of the car air conditioner is bad, it means that the air conditioning refrigeration system is faulty, this first needs to see whether the compressor is normal, and then touch the high-pressure pipe to see if it is hot, if the high-pressure pipe is not hot, the compressor is rotating, it must be insufficient refrigerant.

15 minutes after the air conditioner is turned on, there should be a large temperature difference between the two valves of the outside unit. Frosting of thin tubes indicates a lack of fluoride (if condensation dripping can be formed, it is normal), and frosting of thick tubes indicates poor circulation of the system. If the air conditioner is frosted in a thin tube, it must be less refrigerant, if it is a thick tube frost, one is that the pipe is deflated, and the other is that the evaporator is dirty.

The pressure of 1 hp machine (generally measuring the pressure of the return pipe) is generally around in the summer (MPa is equal to 1 kg, and the pressure gauge is generally MPa, that is, MPa). According to the technical parameters provided to you above, I think you have an idea of your air conditioner.

The low pressure pipe of the car air conditioner is not cool, which should be caused by the lack of refrigerant.

Hello, see if the high-pressure pipe is hot, generally speaking, this phenomenon is a lack of refrigerant.

It doesn't matter if that's wrong. The compressor comes out of the high-pressure and high-temperature gas, and then to the drying bottle and then to the condenser to the expansion valve, which is the high-low conversion, and then to the evaporator to the low-pressure pipe and back to the compressor, and the high-low pressure conversion. This is just the knowledge of the air conditioning system.

When you come out to work, you will naturally understand this knowledge.

Problems with the condenser.

The condenser is a component that is very easy to overlook, and there will be a lot of dust on the condenser when the car is driven for a long time. If you drive on a dusty road for a long time, there will be more dust on the condenser. If there is more dust in the condenser, the heat dissipation effect will be greatly reduced.

The heat dissipation effect is not good, and the air conditioner is naturally not cold.

The air conditioner filter needs to be replaced, and the dirty filter element will also cause non-refrigeration. The following is an introduction to car air conditioners. Concept, the automotive 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. Different types of air conditioning systems are arranged differently. Cars are widely used in integrated air conditioning and heating systems.

Its layout type is to assemble the evaporator, warm air radiator, centrifugal blower, control mechanism, etc., which is called the air conditioner assembly.

The high-pressure pipe of the automobile air conditioner is cold and the low-pressure pipe is not cool, the compressor of the car is damaged, and the low-pressure pipeline should be cold under normal working conditions, and the high-pressure pipeline is hot

1. Disconnect the high and low pressure pipelines of the compressor.

2. Remove the fixing screws on the top of the compressor.

3. Remove the long fixing screw at the bottom of the compressor.

4. Shake to remove the compressor.

5. Install the new compressor in reverse order.

The cause is fluoride deficiency. 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.

And stainless heat-resistant steel seamless steel tubes, these boiler tubes work under high temperature and high pressure, and the tubes will also oxidize and corrode under the action of high temperature flue gas and water vapor, so the steel tubes are required to have high lasting strength, high oxidation resistance, and good structural stability.

During the installation process, it is not allowed to use methods such as forced pulling, strong pushing, strong torsion, or modifying the thickness of the secret wide gasket to make up for manufacturing or installation errors. If it is not possible to carry out and complete the pipe installation work continuously, the open nozzle should be closed when the pipe is bright. The parts of the instrument sampling part on the pipeline should be installed at the same time as the pipe sales road.

When the local curvature correction of the alloy steel pipe is carried out, the heating temperature must be controlled below the critical temperature of the steel.

1.Lack of refrigerant. In summer, the refrigerant in the air conditioning duct of the car may face the risk of evaporation, so once the refrigerant is insufficient, the most direct situation is the decline of the refrigeration function.

2.Compressor belts are too loose due to aging of the belt. The power of the compressor is the output of the engine crankshaft, if the belt connecting the crankshaft and the compressor is loose, it will lead to slippage during transmission, which will make the compressor less efficient.
