Is it noisy to install air conditioner in Wuling Rongguang small truck?

The air conditioner is often turned on and there is no cold air out, go to the 4S shop for maintenance, and the thermostat is used every time, but it didn't take long for the problem to appear again, please help answer it. The air conditioner is often turned on and there is no cold air out, go to the 4S shop for maintenance, and the thermostat is used every time, but it didn't take long for the problem to appear again, please help answer it. If the air conditioner is not cooling, the blower may be broken, or there may be a problem with the compressor or compressor clutch.

The refrigeration principle of the air conditioner is actually very simple, after pressing the AC button, the compressor clutch is combined, so that the engine will drive the compressor to run, and the compressor will continuously compress the refrigerant and send the refrigerant into the evaporation tank. The refrigerant will expand and absorb heat in the evaporation tank, so that the refrigerant can cool the evaporation tank, and the evaporation box can cool the air blown by the blower. It is recommended to check whether the compressor and thermostat of the air conditioner are faulty, if you need to add refrigerant many times, there may be leakage in the air conditioning system.

Wuling Rongguang small card, what to do if the heating of Wuling Rongguang small card is not hot.

1.Start the vehicle and don't turn on the heater immediately In daily driving, many car owners always habitually turn on the heater when they get in the car, but this practice is not correct. Because when the engine is just started in winter, the temperature of the water tank is very low, after the air conditioner is turned on, the temperature in the car will not only not increase rapidly, but will also slow down the speed of the water temperature rise, increase the burden of the engine, accelerate the wear of the engine, and over time it is not good for the engine, generally when starting 3-5 minutes, when the water temperature gauge rises to the middle, you can rest assured that you can use the heater boldly.

2.You don't need to turn on the AC buttonWhen you turn on the heater, remember not to turn on the AC button in the car. Because the AC is the refrigeration switch button of the air conditioner, and the heater is generated by the vehicle, only in this way will it not consume fuel.

3.When the warm air is turned on for a period of time, many car owners may also have a less comfortable sense of pressure on the breath in addition to obviously feeling the temperature in the car, which is due to the fact that the car itself is in a confined space, and the heat exchange is constantly generated in the breathing, and the air will not circulate. More or less alleviated. 4.

Keeping the air dry and smoking less in the car is indeed an environment conducive to the growth of bacteria when the windows are closed for a long time in winter and the heater is turned on. Therefore, we should also pay special attention to preventing the growth of bacteria when using warm air. The method of prevention is not difficult, you can turn off the heating a few minutes before parking, and turn on the natural wind for a while in the state of external circulation, so that the temperature of the air conditioning pipe will be roughly close to the outside temperature, which can ensure the relative dryness of the air conditioning system.

Hello: For the question you asked, the engine noise should have a lot to do with its own wear and the lubricating oil used, mainly check the use of the oil, it is recommended that you first change the viscosity of the oil to try. In addition, if you add poor quality gasoline, it may cause a decrease in engine power, and it will cause more carbon deposits inside the engine, which will also cause the engine to increase noise; In addition, if the engine has a resonance phenomenon, it will also cause the engine to be noisy. And the second problem you mentioned, it may be caused by a slippage of the clutch plate.

You can try it yourself, in the engine idle state, put the gear to tighten the handbrake and then slowly lift the clutch, in the state of light oil, if the engine does not turn off, it means that the clutch plate is slipping. There is also in the normal driving of the vehicle, after the upshift accelerates sharply, if the engine speed rises rapidly, but the vehicle does not feel forward, it should be the clutch plate slippage, then it needs to be replaced, I hope my answer will be helpful to you.

1. The noise of the fan is mainly due to various factors such as bearings, fan blades, and motor dynamic balance, which are related to the machining of the motor and the fan.

2. The noise of the air conditioning fan is not easy to reduce noise, and the effect is not good, the speed is low, and the air volume is small). The noise of the fan is mainly due to the friction of the bearing, and the oil may be reduced by disassembling the scroll fan. As long as it is not worn and moved badly, it can reduce a lot of noise.

It could be that the air conditioner's blower is broken.

1.Carbon deposits can cause insufficient combustion of gasoline and cause the engine to shake. The impact of engine carbon deposition on the car is quite large, first of all, to reduce the engine power, that is, to make the power output uneven and gradually decay, in other words, more and more powerless.

The second is to increase fuel consumption and increase your financial burden. The third is the difficulty of cold start, that is, the difficulty of ignition, it is not easy to get on the car, and finally the carbon deposit in the combustion chamber is strict, and a heavy one will also cause cylinder detonation, and there will be a sound of low-speed acceleration, which will cause damage to the piston and crankshaft, and cause high temperature of the engine, which will seriously affect the safety of the car. Then there is the excessive discharge, which not only fails the annual inspection and inspection, but also directly aggravates the harm of polluting the environment.

2.Transmission load operation will destroy the quality and friction characteristics of the transmission oil, increase friction and wear, transmission noise will follow, and at the same time, sludge (impurities or dirt) will also be generated inside the transmission (such as the valve body), resulting in transmission frustration, out-of-gear, impact, slippage, abnormal noise, delay, high temperature, oil leakage. (Audi and other high-end models will call the police and enter the transmission protection mode) If it is not solved in time, the transmission will be scrapped.

Therefore, only by removing the stubborn dirt and impurities in the gearbox and effectively controlling the working temperature of the gearbox can the gearbox problem be completely solved and prevent its recurrence.

3.Decreased lubrication leads to mechanical wear.

1. The engine has abnormal noise.

Symptom description: There is a lot of abnormal noise in the engine compartment, and most people also judge it to be the abnormal noise of the engine compartment by the sound**, which is usually a metal screeching sound or a howling sound.

Solution: The abnormal engine noise indicates that the technical status of a certain mechanism of the engine has changed. It is mainly caused by excessive wear and tear of some parts or improper assembly and adjustment.

Some abnormal noises can still predict that the engine will be damaged accidentally, so when the engine has abnormal noise, it should be repaired in time to prevent the fault from expanding.

It should be reminded that if it is an abnormal noise in the engine, most of the owners will not be able to solve it by themselves, and it is best to send it to the factory for maintenance.

2. There is abnormal noise in the gearbox.

Symptom description: If there is a "rustle" sound inside the gearbox while the car is driving, and there is no more after pressing the clutch or accelerator, there will be a whistle-like sound when changing gears.

Solution: There are many transmission parts, and the reasons for the sound are more complex, so we should pay attention to whether it is related to a specific speed, such as some planetary teeth that sound at about 50km h.

Whether it is related to certain gears, which is very important for judging the failure of the transmission, if a certain gear sounds, it must be related to the components that affect the transmission of the gear; If all gears sound, it is often a common meshing shaft failure or a lack of oil in the transmission. Whether it is related to specific actions, such as increasing and decreasing gears, starting, rapid acceleration, sharp deceleration, turning, etc., are effective means to judge abnormal noise, among them, changing speed and direction are particularly important for judging the rear axle fault.

If the abnormal noise of the transmission is obvious, it is recommended to send it to a professional repair shop to check the faulty parts, and then replace them.

3. There is abnormal sound of wear.

Symptom description: When driving on the accelerator or brake, there is always some abnormal noise in a certain part of the body, the sound is not loud, and it does not affect normal driving, but it always makes people worry a little about the failure of the body.

Now, with the development of science and technology, the problem of abnormal noise can also be solved by not dismantling and repairing.

There is no way, the original air conditioner is similar.
