Very often, drivers of cars such as Hyundai solaris, notice that the air conditioner, over time, begins to smell not in the most pleasant way, which simply interferes with comfortable driving. Let's say it's very hot in the car and anyone wants to make it comfortable. But what if this is impossible? Open windows are of little help. Drivers do not face such difficulties immediately after the purchase, which means that the reason can only be in pollution. And this is absolutely correct. A car like the Hyundai Solaris has an evaporator. It is also found in other cars with air conditioning, so the article may be relevant not only for the owners of the Korean car industry. This is the very detail that turns hot air into cold air, and later sends it to the legs or face of the driver and passenger. Various auto repair sites have a service such as "flush the evaporator". Cleaning the Hyundai Solaris air conditioner is what you need to do to make the air smell normal again. The car owner always has a choice - self-cleaning or contacting a car service.
However, the price tags for such work are quite large, sometimes they can reach 2-3 thousand rubles for cleaning. The procedure itself, however, lasts 4 hours, no less. The mechanics themselves claim that the entire system is not disassembled, they will not refuel it with anything new, but the comfort from the air conditioner will be felt immediately and the client, at the same time, will be satisfied for a very long time. So what, then, can you do for so long, and even for that kind of money?
Unfortunately, domestic car services practically do not differ from each other. They will spend about an hour on decorating, rolling up the car, then the same amount will go to work, half an hour after that the car will be “tested”, sitting on soft sofas. If you think like that, then it seems that in fact an hour, or even half an hour, will be enough to complete everything that takes almost half a working day in the workshop. So maybe it's not worth spending money, but doing everything yourself? This question often comes to any driver. This question is also relevant for problems with air conditioning. Especially with that part of it, where you do not need to have special knowledge or tools. Moreover, the procedure is not at all complicated.
To understand how to fix a problem, you need to understand where it comes from and after which a smell appears, comparable, perhaps, to dirty, sweaty things. Often motorists on Hyundai Solaris claim that the stench appears after parking in the heat, in other conditions this rarely happens, if not to say that this does not happen at all.
Where did the smell come from?
So where does this smell come from in Hyundai Solaris? When the driver arrived at the place he needed, for example, a store and turned off the engine, then, accordingly, he turned off the air conditioner. What happens to him at this time? The air ducts are still cold, but warm air is already entering them, so moisture condensation begins. And this is not only water, but also another, rather wide range, of various chemical elements. All this mixes with dust and spreads mold and mildew in the evaporator.
Probably not worth mentioning where the smell comes from. Mold, unfortunately, does not smell like violets. Moreover, it is very unhealthy. As soon as the fan turns on, all this is forcefully carried out into the car interior. But some unpleasant things still remain in the evaporator and gradually only multiply there.
How do I fix the problem?
To prevent such problems, you can remember one small rule - turn off the air conditioner shortly before the car stops. Warm air will dry out a little all the moisture that has accumulated there, the air ducts will not be so cold, so condensation can be excluded. But this is only prevention, which should be relevant when there are no problems with odors. If they appear, then the bacteria are already there and they will multiply, even if the air conditioner is not used at all.
All that remains is the cleaning of Hyundai Solaris. But do not do it with ordinary bleach? One can only imagine what kind of smell it will exude. Moreover, although it is harmless, it will not fade away, and no one wants to ride in a gas mask. Then it is worth looking for those funds that will do their job well, but will not spoil anything.
IN medical institutions the problem of hygiene is very acute. It is necessary to maintain cleanliness there everywhere and on everything. But it is logical that especially expensive substances are not used there. So how do you clean the instruments, the operating room? Lizol, it is also called KREZOL solution. This is a substance that can surpass even the most common chlorine in all its properties. It is based on ordinary phenol, exactly the same that is used in preparations for flushing the evaporator and radiator in Hyundai Solaris. There is no need to think that such funds are cheap, sometimes you can pay 1000 rubles or 1500 rubles. Moreover, this may not be enough, sometimes up to 3 liters of such a substance is required for air conditioners.
They are too expensive for the average man in the street. Spend a few thousand to eliminate the smell? Not entirely logical. Of course, there is a way out of this situation. And here is one of them:
- Lysol is used for cleaning, either concentrated or solution. This is not so important here.
- If lysol is pure, then it must be diluted. It is advised to do this in a ratio of 1 to 100, this is quite enough. The result should be a solution of 300-400 ml.
- The finished mixture is poured into any sprayer that is at hand.
- The windows in the car open completely. Better to do the same with the trunk.
- The vehicle starts and the Hyundai Solaris air conditioner switches on for full power... It is best to direct the air currents to the rugs, turn off the direction to the glass. Of course, nothing will happen if the solution gets on the seats or glass, but it's better not to risk it.
- Next, you need to get out of the car and spray the solution into the air intake, which is located at windshield... If you are concerned that the paint will be damaged, it is best to experiment a little in an inconspicuous place.
- Then the engine is turned off, the solution will work and kill bacteria, fungi, and mold.
- After 10 minutes have passed, you need to start the engine again, open the passenger door and turn on the internal circulation. The solution is sprayed in the cabin, under the glove compartment. This is where Hyundai Solaris has a second air intake. He will bring Lizol to the evaporator and radiator.
This completes the cleaning, but it is better, of course, to get to the evaporator and radiator in order to spray them from all sides, but if this is not possible, then the above actions are enough. If all this does not help, then the procedure must be repeated, possibly more than once. There are practically no cash costs when compared with the cost of services in the salon.
Air conditioner forsolaris in basic configuration not included, it must be purchased at an additional cost. But in hot summer weather it is much more pleasant and comfortable to ride with the air conditioner on. So that air conditioner solaris buy worth it.
Hyundai solaris air conditioner - device
The main element of the air conditioner is the compressor, which is installed on top of the engine. It forces the refrigerant to move through the pipes and radiators, cooling and drying the surrounding air. The compressor is driven by a belt from the engine.
The compressor rotor is switched on with the help of a friction clutch, which has an electromagnetic control - then the refrigerant begins to move. At the same time, a characteristic click of the clutch is heard, if not, the air conditioner is faulty.
There are many reasons for this - it can be leakage of refrigerant from the main units of the air conditioner, failure of the pressure sensor, failure of the clutch electromagnet windings, electrical malfunction and other malfunctions that only specialists in their field can find out.
The next most important node is solaris air conditioner radiator... It is installed in the same place where the engine radiator is located using special mounts. The refrigerant, moving along the thin tubes of the radiator, gives off the accumulated heat to the space.
Another important detail is the evaporator, which actually cools the air. It also looks like a radiator, but the opposite happens here - heat from the surrounding air is absorbed by the boiling refrigerant. As a result, the air is cooled to the desired temperature and the air blower supplies it to the passenger compartment.
Condensation forms on the evaporator, which is a favorable environment for all kinds of mold and bacteria, and there comes a time when a bad smell appears in the cabin. To avoid this, the evaporator must be treated with chemicals to prevent bacterial growth before use.
Should be changed regularly cabin filter and clean the drainage tube through which condensate liquid flows.
Every year in the spring, the fins of the air conditioner radiator should be carefully washed. In this case, you cannot use a jet of water under pressure, as very thin tubes can be destroyed.
Today, a rare car owner does not know what an air conditioner in a car is. Its presence is gradually moving from the category of luxury to a basic necessity. Like any other complex mechanism, the air conditioner sometimes refuses to fulfill the duties assigned to it. Many drivers are perplexed by this problem, they do not know what to do in this case. Let's try to understand this problem together.
Possible malfunctions
It is possible to identify the air conditioner malfunctions on your own, but it is better to entrust the elimination of some of them to specialists. The most important node there is a compressor in the air conditioning system. It is with him that most of the malfunctions are associated.
What signals a problem with the compressor
The presence of constant noise or when switched on to the operating mode indicates that he is "sick" and needs treatment. The culprits of all this may be:
- Drive shaft bearing output.
- Incorrect drive belt tension adjustment.
What do they do in this case:
- Check and, if necessary, correctly adjust the belt tension.
- Disconnected electromagnetic clutch and the compressor shaft is turned by hand, which should turn freely. You do not need to start the engine.
- If you hear extraneous sounds during rotation, and significant efforts are also required - it is necessary to change the bearing.
If this is not done in time, additional problems may arise. When turning the bearing in the seat, the front cover of the unit is sometimes damaged. Refrigerant leakage can occur due to cracks in the housing. When the bearing "wedges", the electromagnetic clutch fails due to overheating.
If extraneous noise appears only after turning on the drive of the unit, then the reasons will be different:
- While servicing the compressor, it was not refilled or refilled by unskilled or careless workers.
- Disturbance of refrigerant circulation in the system.
- Fan failure or contamination of the air conditioner radiator.
If you postpone the elimination of these malfunctions for a long time, you can wait for the compressor to jam. Keep the radiator clean, which can get contaminated with various debris while driving. For the manufacture of radiators, aluminum alloys are used, which corrode from chemicals on the roads in winter.
Ventilation
4. Adjust the fan speed to your liking.
Heating
1. Set the operating mode selection knob to position.
2. Set the air intake switch to the outdoor (fresh) air intake position.
3. Install the thermostat knob as desired.
4. Adjust the fan speed to your liking.
5. If heating with a decrease in air humidity is required, turn on the air conditioner (if available).
When fogging up windscreen set the operating mode selector to or.
To prevent dust or unpleasant odors from entering the passenger compartment through the ventilation system, temporarily set the air intake mode switch to the recirculation position.
Be sure to return the adjuster to the outside air intake position when the source of pollution is behind to allow fresh air to enter the vehicle. This will ensure that the driver remains alert and comfortable for his work.
The air intake for the heating and air conditioning system is through a grill located directly in front of the windshield. Make sure that it is not covered by leaves, snow, ice or other foreign objects.
To prevent fogging of the windscreen with inside set the air intake mode switch to the position corresponding to the outside air intake, the fan speed control knob and the thermostat knob can be set at your discretion.
Air conditioning
All air conditioners installed on HYUnDAI vehicles are filled with r-134a refrigerant, which is safe for the environment.
1. Start the engine Press the air conditioner start button.
2. Set the mode selector to the position.
3. Set the air intake mode switch to the recirculated air position.
4. Adjust the fan speed control knob and thermostat knob in such a way as to obtain the most comfortable conditions in the passenger compartment.
When maximum cooling is desired, set the thermostat knob to the far left (MAX A / C position) and then set the maximum fan speed.
NOTE
When using the air conditioner, keep a close eye on the engine coolant temperature gauge when driving uphill or in heavy traffic in hot weather. Running the air conditioner can cause the engine to overheat. If the engine coolant temperature gauge indicates overheating, leave the fan on, but turn off the air conditioner.
When the windows are open and the ambient humidity is high, the operation of the air conditioner may cause moisture droplets to form inside the vehicle. Since excess moisture can lead to electrical failure, the air conditioner should only be operated with the windows closed.
Air conditioner operation tips
If the car has been parked in direct sunlight during hot weather, briefly open the car windows to let the hot air out of the passenger compartment.
To help reduce fogging of the interior glazing in rainy or humid weather, reduce the humidity in the cabin by turning on the air conditioner.
During the operation of the air conditioner, you may notice a slight change in the crankshaft rotation speed depending on the switching on or off of the air conditioning compressor. This phenomenon is normal.
Operate the air conditioner once a month for at least a few minutes to maintain its optimum performance.
When the air conditioner is operating, you can notice how clean water drips (or even pours) from the passenger side onto the ground. This phenomenon is normal.
Operating the air conditioner in recirculation mode provides truly maximum cooling intensity, but prolonged operation in this mode can lead to the fact that the air in the passenger compartment becomes stale.
During the cooling process, an air flow with water condensate may appear, which is associated with the ingress of moist air into the system at a high cooling rate. This is the normal operation of the system.
If the air conditioner is turned on for excessive cooling, the difference between outside and windshield air temperatures can cause moisture to build up on the outside of the windshield, resulting in loss of visibility. In this case, set the operating mode selection knob to the position and reduce the fan speed.

Hyundai Solaris air conditioning system
On hyundai vehicles Solaris has a compressor-type air conditioning system. Heater and air conditioner evaporator assemblies are arranged in one unit. The controls for the air conditioning system are located in a block common with the controls for the heater.
Figure: 2. Air conditioning compressor:
1 - clamping disk; 2 - drive pulley; 3 - front cover of the case; 4 - block of the electric connector of the coil of the electromagnet; 5 - low pressure pipeline attachment flange; 6 - valve block cover; 7 - high pressure pipeline attachment flange; 8 - fastening eye; 9 - pump housing; 10 - filler plug; 11 - pressure plate damper
Compressor (fig. 2) circulates the refrigerant in the system. The compressor shaft is mounted in the aluminum front cover of the housing on bearings and is sealed on the side of the drive pulley with an oil seal.
The compressor drive pulley 2 is mounted on a double-row ball bearing and rotates constantly when the engine is running. When the air conditioner is turned on, torque is transmitted from the pulley to the compressor rotor through friction clutch with an electromagnetic drive.
Note
If the system is working properly, when the air conditioner is turned on, a click is heard - this is the clutch pressure plate 1, under the action of an electromagnet, engages with the drive pulley 2, and the compressor rotor begins to rotate.
But during the operation of the air conditioner, the following compressor malfunctions may occur.
1. If, when the air conditioner is off, the clutch makes extraneous sounds during rotation, heats up or a burning smell appears, then, probably, its bearing has begun to collapse.
In this case, the bearing must be replaced (see Replacing the Drive Pulley Bearing). In some advanced cases, it may be necessary to replace the compressor clutch assembly or its component parts.
2. If, after turning on the air conditioner, a click is not heard, then the following malfunctions are possible:
- a refrigerant leak has occurred and the control system blocks the activation of the compressor;
- the pressure sensor in the system is out of order;
- malfunctions in the electrical circuits of the control system;
- the coil winding of the coupling electromagnet burned out;
- the engine control unit for any reason (high engine coolant temperature, high engine speed) blocked the inclusion of the compressor.
3. If the clutch rotates easily and freely, but when the air conditioner is turned on, you can clearly hear extraneous noise or even the engine stalls, then, most likely, the compressor is jammed. The internal pumping part of the compressor cannot be repaired. In this case, the compressor will have to be replaced.
4. And the last, most unpleasant option.
The click is heard, the clutch easily rotates the compressor shaft, and there is no cooling of the air in the cabin. In this case, the compressor runs dry, pumping nothing. Only an experienced specialist with special control and diagnostic equipment can determine this malfunction.
The most accurate determination of the cause of the malfunction can be after a complete diagnosis in a specialized service center for the repair of car air conditioners.
Figure: 3. Condenser:
1 - pipe fastening flanges; 2, 4 - condenser tanks; 3 - honeycomb; 5 - receiver dryer
Condenser (air conditioner radiator) (Fig. 3) multi-flow type is located in front of the radiator of the engine cooling system. It is attached with four brackets to the radiator frame. Condenser honeycombs are made of flat thin-walled aluminum tubes with internal longitudinal baffles for rigidity and external fins to improve heat transfer. Aluminum tanks with flanges for connecting pipelines and receiver. The tanks are divided in height into sections, therefore, passing through the condenser, the refrigerant flow changes direction several times. In the condenser, the vapors of the refrigerant compressed by the compressor are condensed and the heat released during this is removed to the ambient air.
When the air conditioner is turned on, the engine control unit turns on the power circuit electric fan an engine cooling radiator, which improves heat exchange in the condenser and reduces the pressure in the air conditioning system.
Helpful advice
At least once a year, preferably before summer operation, flush the fins AND condenser honeycomb from adhering dirt, dust and deicing agents B ... This will improve heat transfer, reduce system pressure and increase the service life of system elements.
Do not use water-jet cleaners to wash the condenser. high pressure... This could damage IN thin-walled finning plates.
Even with regular cleaning, the condenser needs to be replaced more often than desired. The fact is that he is the first to take on the flow of deicing agents, dirt and stones from the road.
And the walls of the tubes are thin. In most cases, the condenser is damaged by corrosion in the third or fourth year of operation.
If, as a result of corrosion, the tightness of the condenser is broken, then it is more expensive to repair it. Even if the argon welder manages to patch the hole, a leak may soon appear elsewhere.
By the way, the pressure in the system on hot days can reach 25-28 bar.
In addition, one should take into account the complex structure of the condenser tube: along it is divided by partitions into channels, so it is highly likely that after welding some of the channels will be blocked. Accordingly, the dissipated power will drop and the operation of the air conditioner will deteriorate, especially in traffic jams and in hot weather.
After each experiment with condenser patching, it will be necessary to pay for removal / installation, welding of the condenser and charging the system with refrigerant. So it's best to install a new condenser right away.
Evaporator located in the block of heating (air conditioning) and air ventilation in the passenger compartment. The evaporator is made of aluminum tubes with external fins to improve heat transfer. Passing through the tubes of the evaporator, the boiling refrigerant actively absorbs heat from the air blowing over the outer ribbed surface of the tubes. The air is cooled and supplied to the passenger compartment by an air blower.
Note
When the air passing through the evaporator is cooled, the water vapor contained in it condenses.
Condensation is discharged through a drain pipe located on the lower right side of the body panel under the vehicle floor.
If the ambient air humidity is high, a puddle of water may form under the car, which is an indirect sign of the health of the air conditioning system.
Warning
During the operation of the car, particles of road dust and dirt settle on the outer surface of the evaporator, wet from condensation.
This layer becomes an excellent environment for life and rapid reproduction of putrefactive bacteria and fungal cultures. Over time, an unpleasant odor appears in the car.
It is felt especially strongly when the air conditioner is turned off and in wet weather.
In order to minimize the risk of this problem, when buying a new car, it is necessary to carry out preventive treatment of the evaporator with special chemicals, regularly replace the cabin filter and clean the drain pipe. If, despite the measures taken, the odor still appears, contact a specialized car air conditioner repair service to disinfect or rinse the evaporator.
If very dirty, the evaporator will have to be replaced.
On the side surface of the evaporator there is a flange for attaching a thermostatic valve.
Thermostatic valve block type located in the evaporator housing. The valve is attached to the piping and the evaporator with flange connections. Having passed through the throttling hole in the valve body, the liquid refrigerant sharply decreases its pressure and begins to boil. A regulating element is installed in the valve body, which changes the flow area of \u200b\u200bthe throttling hole depending on the pressure and temperature of the refrigerant. The regulating element is adjusted at the factory and cannot be adjusted during operation.
Receiver drier installed on the condenser on the left side and forms a non-separable unit with it. Inside the housing there is a filter element (cartridge) filled with desiccant granules (silica gel). The liquefied refrigerant passing through the receiver is cleaned of possible impurities, dirt and moisture. At the bottom of the housing there is a hole for replacing the filter element.
Warning
In case of repair or replacement of the air conditioning system elements, if it was in an open state (some units were removed, pipelines destroyed, etc.), the receiver-dryer cartridge must be replaced. Otherwise, after charging the system, the refrigerant will not dry out and acids may form inside the system, which will destroy the inside of the air conditioner parts.
Pipelines connect all the elements of the air conditioning system into a single sealed circuit. Pipelines and their flanges are made of aluminum alloys.
Protect metal piping from dents and kinks. Any narrowing of the flow area of \u200b\u200bthe pipeline leads to a decrease in the performance of the system.
O-rings made of neoprene are installed at the joints of the individual elements of the system.
During the repair of the system, when the pipe sections are disconnected, the O-rings must be replaced. Tighten threaded pipe connections to the recommended torque.
Weak or excessively tight tightening will deform the sealing surfaces and leak refrigerant.
Service valves for connecting diagnostic and refueling equipment are located on pipelines.
Note
This is how the service valves of the low AND and high B pressure. The valves are closed with threaded caps to protect them from dirt. The caps are marked with the letters "H" and "L" of the high and low pressure lines, respectively.
The valves have spools that are similar in design to the spools of wheel tires, but differ from them in size.
A special wrench is used to turn the spools in and out.
Warning
Check the presence of refrigerant in the system by pressing on the spools of service valves is prohibited, since after such a check the valve spool may not close completely and refrigerant will leak from the system!
Pressure meter installed in engine compartment on the right side of the high pressure pipeline section.
By sensor signals the electronic unit engine control turns off the air conditioner compressor when the system is depressurized or an emergency increase in pressure in it in order to protect the compressor from overloads.
Control block the heating, air conditioning and ventilation system is installed in the instrument panel.
The controls for the heating, air conditioning and ventilation system are described in detail in Sec. Vehicle device, see Heating (air conditioning) and interior ventilation.
Sunlight sensor located in the dashboard under the windshield. To increase the efficiency of the climate control system and more comfortable distribution of air flows, a sun sensor is installed on the instrument panel near the windscreen glass. Depending on the degree of heating of the passenger compartment by the sun's rays, the sensor signals the air flow to the face or legs of the driver and front passenger.
Refrigerant... The system is charged with HFC134a (R134a) refrigerant. The total filling volume is (450 ± 25) g.
Added to the refrigerant special oil FD 46XG (PAG) for compressor lubrication. It is strictly forbidden to use other types of refrigerants and oils in the system.
Note
During operation car air conditioner periodically there are situations when the air conditioning system needs to be serviced or repaired.
For this, modern diagnostic and repair equipment is used. The most common situation is the depressurization of the system and the release of refrigerant from it.
Highly sensitive halogen leak detectors with audible indication are used to locate leaks.
In some difficult cases, the so-called ultraviolet diagnostics of the tightness of the air conditioning system is used.
The method consists in the introduction of a special dye into the system in micro doses.
In places of microleaks, the dye, together with the refrigerant, gradually comes out onto the outer surface of the system elements.
During the inspection of the system, the dye begins to glow (fluoresce) under the influence of ultraviolet rays of a special lamp ...
... and refrigerant leaks become visible.
It should be noted that the dye does not have any negative effect on the system. It can remain in the refrigerant and circulate through the system for as long as desired and only serve its purpose when a leak occurs.
After repairing the air conditioner, it is necessary to evacuate and fill the system with the appropriate refrigerant (R-134a).
The amount of air conditioner filling is individual for each car model.
To carry out a high-quality refueling of an automobile air conditioner, you need:
- precision gauge blocks with special connecting tips;
- two-stage vacuum pump for complete removal of air and water vapor from the system;
- high-precision (scale division no more than 5 g) scales for dosing the charged refrigerant.
In connection with specific features repair of the air conditioning system in this section describes only work on the removal and installation of individual elements and the system control unit. Work related to charging the system with refrigerant should be carried out in specialized service centers.
Warning
The air conditioning system is charged with high pressure refrigerant. The contact of liquid refrigerant on the skin of a person causes severe frostbite, therefore, all work related to the maintenance, repair or dismantling of elements of the air conditioning system, if possible, should be carried out in specialized service centers equipped with professional technological equipment. Take precautions when working on your own.
