For too much refrigerant, it is generally caused by overfilling the refrigerant during maintenance, because the ratio of refrigerant to the volume in the air conditioning system is required. If the proportion is too large, it will affect its heat dissipation, that is, the more heat dissipation, the greater the cooling capacity; Conversely, if the heat dissipation is less, the cooling capacity will be small. Similarly, if too much cooling oil is added during maintenance, the heat dissipation of the refrigeration system will also decrease.
Solution: If there is too much refrigerant in the car air conditioner, you can slowly release some at the maintenance port on the low-pressure side of the air conditioning system.
2.There is not enough or too little refrigerant in automotive air conditioners.
Most of the causes of insufficient air conditioning in automobiles are caused by the leakage of refrigerant in the system. If there is not enough refrigerant in the air conditioning system, the amount of refrigerant injected into the evaporator from the expansion valve must also be reduced, when the refrigerant evaporates in the evaporator. As a result, the amount of heat absorbed will decrease, and so will the cooling capacity.
Solution: If the refrigerant is insufficient, the refrigerant should be added, but when adding the refrigerant, it should be noted that if the refrigerant is added on the low pressure side, it is forbidden for the refrigerant bottle to fall to the ground, and if it is added from the high pressure side, the engine should be prevented from starting.
3.There is water infiltration in the air conditioning and refrigeration system.
Caused by insufficient refrigerationThere is a part of the refrigeration system is the drying tank (bottle), and one of its main tasks is to receive the water in the refrigerant to prevent the refrigeration capacity from decreasing due to excessive water in the refrigerant. However, when the desiccant in the drying tank is in a state of moisture absorption saturation, the water can no longer be filtered out, when the refrigerant saves the hole through the expansion valve, due to the decrease of its pressure and temperature factors, the water in the coolant will produce freezing phenomenon in the small hole, and cause the refrigerant to flow unsmoothly, the resistance increases, or simply cannot flow.
Maintenance method: Stop for a while, and after the ice melts, the refrigeration system will appear in a normal state again. This is an important way to confirm the presence of moisture in the system.
In order to better detect the amount of moisture in the system, the desiccant used in some cars is blue when it does not contain water, and once the moisture is excessive, the desiccant will turn red, which can be seen on the side vision hole on the car drying tank. In case of excessive water content in the refrigerant, the desiccant should be replaced or the drying tank should be replaced, and at the same time, the system should be re-vacuumed and re-injected with a new appropriate amount of refrigerant.

Anonymous users2024-02-09There are many reasons why the Roewe RX5 air regulator does not cool, including clogged air controller filter element of the car, the car cannot start, the air regulator compressor is damaged, and the engine belt is slippery. , which will be analyzed in detail below. 1.
Air filter blockage: The blockage of the air filter element in the car is the weight of the [k0] adjustment system that does not cool.
There are many reasons why the Roewe RX5 air regulator does not cool, including clogged car air regulator filters, cars that cannot start, damage to the compressor of imitation air regulators, engine belt slippage, etc. , which will be analyzed in detail below.
1.Clogged air filter:
Clogging of the automotive air conditioning filter element is an important reason why the [K0] conditioning system does not cool. The air conditioning filter element is a consumable, which needs to be replaced when the car is driving about 6000 kilometers, otherwise it will affect the normal operation of the air conditioning system and may be empty.
2.The car does not start:
If the car doesn't start, the engine won't work, so the compressor won't start. In this case, you just need to start the car, and use the engine to power the compressor, you can use the air-adjustable refrigeration system.
3.Empty compressor damaged:
Automotive compressors are an important part of air-cooled or heated modulation. There are many reasons why it is damaged, and it needs to be checked by a professional in a repair shop or 4S shop.
4.Engine belt slippage:
When the engine belt slips, it will affect the transmission of power to the car, which will affect the normal operation of the empty compressor. This situation requires timely replacement or repair of the engine belt.
The Roewe RX5 air conditioner button is unresponsive.
The failure of the Roewe RX5 air conditioning may involve many reasons. Here are some possible scenarios:
1.There is a problem with the condenser. The most common situation is that too much dust on the condenser causes poor heat dissipation of the condenser, which in turn leads to no cooling.
It is normal for a car to cause a lot of dust on the condenser after a long drive. If you drive on a dusty road for a long time, there will be more dust on the condenser. If this is the case, the solution is to clean the condenser.
2.Empty refrigerant leaks, or the amount of empty refrigerant is insufficient. If both the compressor and the internal and external units are working, this is most likely the reason.
Solution: Add empty refrigerant.
3.The car was dirty and loose. Solution: Adjust the belt tightness.
4.The compressor is broken. As we all know, to turn on the air is to press the A C button, and the A C button is the switch that controls the compressor. If the compressor is not working, the air naturally does not cool.
Solution: Repair or replace the compressor.
The above are only some of the possible reasons, because you can't see the real car, so you can't make an accurate judgment. What exactly happened still needs to be examined by professionals to determine. Only by identifying the problem can we remedy it.

Anonymous users2024-02-08What is the reason why the Roewe RX5 air conditioner is not cooling? What is the reason why the Roewe Lupai RX5 air conditioner is not cooling? Reasons why car air conditioner does not refrigerate and how to solve it:
1. Lack of refrigerant: resulting in insufficient refrigeration dose in the pipeline of the air conditioning system, the pressure decreases, and the heat taken away becomes smaller. Generally speaking, there will be a slight leak in the air conditioning line or condenser, which is a normal phenomenon.
Since the refrigerant is not covered or too little, it must be supplemented, but it should be noted that if it is added from the low-pressure side, it is forbidden to pour the refrigerant bottle; If added from the high-pressure side, the engine is not started. After filling, you should check whether the leakage is serious. 2. No maintenance for a long time
Air conditioner filters and condensers that are too dirty or clogged can also cause poor refrigeration. If you really don't have the habit of regularly maintaining the air conditioning system, then you need to clean the air conditioning system, not to mention replacing the air conditioning filter, the method is very simple to get started, almost no learning cost, and the owner can replace it regularly. @2019

Anonymous users2024-02-07What is the reason why the Roewe RX5 air conditioner is not cooling? What is the reason why the Roewe RX5 air conditioner is not cooling? Lack of refrigerant, dirty cabin air filter and condenser, electrical problems.
The following are the reasons why the Roewe RX5 air conditioner is not refrigerated: 1. The lack of refrigerant is too cold: the refrigeration dose of the air-conditioning system pipeline is insufficient, the pressure is reduced, the heat taken away becomes smaller, and the air-conditioning pipeline or condenser will have a slight leakage, which is a normal phenomenon, and the refrigerant is insufficient or too little, and it should be supplemented.
2. Dirty air conditioning filter and condenser: If there is no maintenance for a long time, the air conditioning filter and condenser will be dirty, or blocked, and the cooling effect will be poor. If you do not have the habit of maintaining your air-conditioning system regularly, you should do a major cleaning of the air-conditioning system and replace the air-conditioning filter.
3. Circuit problems: Preliminary check whether there is a problem with the compressor by directly supplying power to the compressor electromagnetic clutch. Generally speaking, direct damage to the compressor is rare, and if it is a problem with the compressor, it is recommended to leave it to a professional to deal with the parsley.

The fuel consumption of 100 kilometers in the city is about the same, which is already a very good result for such a large car.
1.The quality is decent, in the past few years on the market, the market reputation is good, and the sales volume has not changed much, unlike Ruifeng S3 and other models, 2Many people are chosen because of the high appearance and good interior of the Roewe SUV, in fact, his three major pieces are also good, the engine is reliable, the gearbox has no major problems, the driving experience is also very smooth, the i5 is also very popular, the reputation and cost performance are very high, no less than the Geely that is now very hot, the Roewe interior is definitely a highlight, I went to 4S last month to see it once, the sense of science and technology is bursting, compared with the current joint venture car, the reputation of Roewe 360 and other cars is good, I suggest you ask your friends who have driven Roewe, I haven't driven it, I don't know how durable Roewe is, it's okay to cherish a little and drive it for six or seven years. >>>More
The process of your running is relatively long, and the engine oil burns the oil, the temperature is higher than before, you need to change to a higher viscosity oil, high temperature protection is better, the quality of the engine oil used is also high, you can use 0w40 model. When choosing a motor oil brand, you should also use a well-protected, high-temperature resistant and clean-friendly oil, I have always used GT engine oil, PAO base oil, which is more resistant to high temperature than the general fully synthetic engine oil, cleaning and protection are very good, and the performance in all aspects is very good, under normal circumstances, there is no problem in running 12000 kilometers, my car has been burning engine oil for more than a year, yoga's has always been GT engine oil, although the car still burns engine oil, but with the car with the engine oil, less to add, Nothing else.
The Roewe RX5 is not very frustrating, and the shock absorption of this car is not very hard. Sales of this car are also particularly high.
Mine is the 17 manual Internet version of the brand on April 17 Now more than 37,000 kilometers Manual fuel saving I have been looking at it for two years It is the screen system that has had a problem with the 4S shop to fix it Nothing else has gone wrong, 18 years of self-driving out of about 5500 kilometers There has been nothing wrong along the way. Over the speed bump is indeed more dynamic, the sound insulation is not too good, especially the speed is fast, but the cost performance is okay The space is large enough The appearance is also very good Fuel efficient. After all, the price is here.
