Mitsubishi air conditioners: possible malfunctions, refueling and maintenance. Mitsubishi air conditioners: possible malfunctions, refueling and maintenance Video “Detailed instructions for refueling an air conditioner”

Everyone knows what an air conditioner is and what functions it performs. The air conditioner is one of the components of the comfort of a motorist behind the wheel. In this article we will talk about what kind of malfunctions the air conditioner of a Mitsubishi car can have and how it is refueled.

Common breakdowns

So, what malfunctions are typical for climate control systems of Mitsubishi Pajero XL, Lancer 10 or other models:

1. Tube leaks. Aluminum tubes become unusable over time using Lancer 10 or Pajero XL as a result of exposure to rust. However, in this regard, not only tubes fail, but also other components of an automobile air conditioner, for example, rubber gaskets and seals. As a result of long operation, as well as exposure different temperatures and careless assembly and disassembly seals can harden. But, as a rule, it is the pipes of the climate control system that leak on the Pajero XL or Lancer 10. In addition to tubes, the problem of a lack of tightness may lie in the cracks that form on the compressor. To prevent this, regularly inspect all elements of the system and change tubes in time.
2. Compressor or radiator failure. Such a breakdown is one of the most unpleasant, since it entails large labor and material costs. As a rule, problems associated with a radiator or compressor on a Pajero XL, Lancer 10 or any other Mitsubishi model are associated with depressurization and lack of proper maintenance. If the car owner does not pay attention to diagnostics and system checks in time, then dust and moisture can get into it, which leads to corrosion. Failures in the operation of climate control can also be associated with insufficient cooling of the radiator. If the radiator fan fails, first of all, you need to check the contacts - they may have oxidized. But if everything is in order with the radiator fan, it is possible that dirt has accumulated between the radiators, which prevents the system from functioning normally.
3. Electrical breakdowns. If the Lancer 10 or other model air conditioner does not work, this may be due to electrical malfunctions. As a rule, in this case, again, we are talking about contacts. They oxidize, rot, so from time to time it is necessary to diagnose and replace them.
4. system impassability. In some cases, the air conditioner on Lancers 8, 9, 10 does not work for this reason. Usually we are talking about a thermostatic expansion valve - dirt can simply get there. Flushing can solve such a problem in the functioning of the air conditioner - as a rule, after that the climate system works normally.
5. Too high pressure. It may appear as a result of too much freon filled into the system or from too weak cooling of the radiator.
6. Inoperability of the air dampers or clogging of the cabin filter element. Often, owners of Lancer 10 and other Mitsubishi models with air conditioning are faced with this. It happens that the climate control works properly, however cold air does not enter the salon. There is a possibility that this is due to a breakdown of the air damper actuator.
7. Problems in the operation of the climate control unit. In principle, if problems arose with the “brains”, then it will not be possible to solve them without equipment. Such a malfunction can only be solved by flashing the unit.

How to fill with your own hands?

To refuel yourself, follow these steps:

1. First, put on your gloves. Depending on the refill kit you will be using, assemble following the instructions described in the instructions.
2. In accordance with the service book for your car, you need to find a hole in the system low pressure. Usually the nozzle that comes with the refill kit is only suitable for this outlet, so you should not make a mistake. Mitsubishi hole high pressure its shape differs from the low-pressure orifice.
3. Before opening a hole, the area around it must be thoroughly cleaned. This is done in order to prevent accidental entry of garbage into the system.
4. Next, connect the hose of the refill kit to the hole you found.
5. Put the car on the parking brake, turn on the neutral speed. Start the engine and carefully, slowly, unscrew the valve of the freon container for refueling. Sit in the driver's seat and step on the gas a little - this will allow consumables disperse in the system in the most optimal way. Accelerate until you feel that cool air has appeared in the cabin from the air dampers. Then simply turn off the engine and unscrew the filler hose.

Be careful, the filling of household and car air conditioners is different. The air conditioner is filled with oil, different freons. Experts recommend changing the dehumidifier at least once every two years, otherwise the compressor will fail, it will drive aluminum shavings and you will still have to flush the system. It's better to have it done by the experts!

Video "Detailed instructions for refueling the air conditioner"

You can learn more about how self-refueling of a car air conditioner is carried out in the video below (the author of the video is Viktor Manyukhin).

The Mitsubishi Lancer X car has established itself as a modern reliable vehicle. The operation of the car's air conditioner is not satisfactory. However, like most systems, it requires maintenance and timely maintenance.

The main reasons for extraordinary repair work are:

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!

• damage to the integrity and malfunction of the radiator of the Lancer X air conditioner;
• failure of the air conditioning compressor bearing;
• the need to refuel and clean the air conditioning system;
• reduction in compressor performance;
• depressurization of the system;
• malfunction of pressure and temperature sensors of the air conditioning control system;
• the climate control unit does not work;
• electrical wiring damage.

Causes and troubleshooting of the main components of the Lancer 10 air conditioner

The cause of the malfunction may be damage to the radiator structure due to the ingress of foreign objects, parts of a broken fan blade, or a traffic accident.

When choosing and buying a radiator, it is necessary to pay attention to the conformity of the design of the joints of the pipes of the air conditioning system installed in the car.

The original radiator of the Lancer 10 air conditioning system is quite expensive. Restoring the integrity of the radiator structure is possible only in case of minor damage. Cheaper to replace with non-original models. The table shows the approximate cost of the original and radiator and its analogues from various manufacturers.

It is necessary to check the conformity of standard sizes and seats on the official website of the manufacturer.

The choice of a specific model of an air conditioner radiator depends on material resources. If it is planned to produce self-replacement radiator, it is better to make a choice in favor of a non-original model, especially since technologically it is not difficult to replace the radiator.

Compressor bearing failure

The compressor bearing in the air conditioning system is under constant mechanical stress. In this regard, it wears out quite quickly, especially since it is not located in best conditions operation. Main signs of wear:

• extraneous high-frequency sound in the compressor area;
• mechanical knock;
• heating of the compressor during operation.

In the event of the first signs of bearing wear, it must be replaced. The sequence of work to replace the bearing:

The cost of analogues of bearings Lancer 10 1.8 B is in the range from 400 to 1,000 rubles. Some models from different manufacturers are shown in the table.

In some models of compressors, a size of 35x50x20 can be installed, so before purchasing a bearing, the assembly must be dismantled.

Refueling the air conditioning system

The air conditioning system requires periodic charging of refrigerant. Official Lancer X service centers fill the air conditioner with HFC-134a refrigerant, 480-520 grams by volume.

Refueling is required in the following cases:

• violation of the tightness of the system after repair;
• loss of refrigerant during long-term operation, leaks;
• when necessary for routine maintenance.

If the air conditioner control unit, using a pressure sensor in the system, detects a value less (or more) than the critical one, it sends a signal to block the activation of the air conditioner clutch. Thus, if the charging of the system is carried out incorrectly, the air conditioning system will not work. High-quality refueling requires special equipment, the availability of appropriate certificates. Self-refueling is not recommended.

Cleaning the air conditioner evaporator

It is produced when foreign odors appear in the cabin after the system is turned on. Can be done on your own by special means, For example:

Bacteria can accumulate in the condensate drain tank, which helps to destroy this product. It is better to pour this remedy inside drainage system through the drain hole. To examine the contamination of cavities, good illumination is required. Fig. 7

Troubleshooting the air conditioner control unit

To eliminate errors in the control unit, it is necessary to conduct computer diagnostics. After fixing and decoding the error code, you should not immediately change the sensors or other devices that the scan shows. It is necessary to check the correctness of the wiring of the air conditioning system according to the scheme. To do this, it is better to use the services of an auto electrician.

Timely and high-quality maintenance of the air conditioning system is a sure guarantee of its constant performance.

• Diagnostics, refueling and repair of Mitsubishi Lancer X air conditioner

Air conditioning is enough reliable device which maintains a certain temperature in the car interior. This unit operates in difficult conditions - sudden changes in temperature, constant exposure to vibrations and other factors dramatically reduce the life of some parts and assemblies of the air conditioner. Therefore, the repair of car air conditioners is a fairly popular service.

Specialists of JapAvto technical centers carry out a full range of services for the diagnosis, repair and refueling of Mitsubishi Lancer X air conditioners. All work in JapAvto technical centers begins with diagnostics - repairing air conditioners is no exception. Diagnostics with the help of special equipment indicates problems - refrigerant leakage, malfunctions of climatic equipment units.

Most often, repair of the air conditioner consists in restoring the tightness of the unit. This problem is solved in two ways. The first method is to install new spare parts instead of failed parts, the second is to eliminate depressurization using argon-arc welding and powder-plasma spraying.

Our specialists will repair Mitsubishi Lancer X air conditioners of any complexity. We carry out repair and production of highways, production of rear contours of air conditioners. With the help of argon-arc welding and powder coating We refurbish evaporators and condensers.

Our craftsmen carry out disinfection of evaporators, replacement of bearings and complete renovation compressors car air conditioners. Also here you can flush the air conditioning system, purchase spare parts for the repair of units of this type, buy new and used compressors.

One of the most difficult cases is a compressor failure. In this case, most often it is necessary not only to change this entire assembly, but also to carry out a number of additional procedures - to replace the receiver-dryer and flush the entire system.

After the repair work is completed, the unit is refueled. Before refueling, an additional check of the tightness of the cooling system is carried out. To check the tightness, special equipment is used - a leak detector. Also, the test can be carried out using a vacuum. The air conditioner is inspected, the parameters of its operation are measured, after which the refueling itself is already carried out, which usually takes no more than half an hour.

Refueling of Mitsubishi Lancer X air conditioners is carried out by our specialists with special care - the operation of the entire cooling system depends on the correct filling. If the pressure in the system after refueling is increased, the air conditioner may fail, if the unit is not refueled, then its operation will be inefficient, therefore, when refueling, all manufacturer's recommendations must be strictly observed.

Work aimed at restoring the efficiency of climate technology requires large financial costs. To avoid them, it is recommended to carry out diagnostics of the unit in a technical center at least once every two years. It is also recommended to turn on the device for a short time and in winter time also - this will help to avoid some breakdowns.

Mitsubishi Lancer 10. Heater and air conditioner - part 2

Compressor 7 (Fig. 12.3) is mounted on the engine and is driven by a V-ribbed belt for the drive of auxiliary units. Compressor of axial-piston type, variable capacity. The compressor shaft is installed in aluminum case on two needle

bearings and sealed with an oil seal on the side of the drive pulley. The compressor has seven pistons with Teflon O-rings. Lobe type valves. The capacity regulator is built into the compressor housing. Drive pulley installed

on a double-row ball bearing and when the engine is running, it constantly rotates. When the air conditioner is turned on, the torque from the pulley to the compressor shaft is transmitted through a friction clutch with an electromagnetic drive. Compressor

circulates the refrigerant through the system and creates the pressure necessary for the refrigerant to flow through the thermostatic valve opening.

Condenser 5 of the multi-flow type is installed in front of the radiator of the engine cooling system. Honeycombs are made of flat thin-walled aluminum tubes with internal longitudinal baffles to ensure rigidity. Tanks aluminum with flanges for connection of tubes. The tanks are divided into sections according to their height. The refrigerant flow changes direction several times as it passes through the condenser. In the condenser, the vapors of the refrigerant compressed by the compressor are condensed, and the heat released in this case is removed to the surrounding air.

Receiver-drier 3 is installed on the left side of the condenser. The body of the receiver-drier is made of aluminum alloy. Inside there is a filter element and a cavity filled with desiccant (silica gel) granules. The liquefied refrigerant passing through the receiver is cleaned of possible impurities of dirt and moisture.

Thermoregulatory valve 12 of block type is located under the hood near the motor shield, has flange connections. The pressure of the compressed refrigerant after passing the throttling hole in the valve body drops sharply - it begins to boil. A control element is installed in the valve body, which changes the flow area of ​​the throttling hole depending on the pressure and temperature of the refrigerant.

Evaporator 11, located in a common housing with a heater, is made of aluminum tubes with fins to improve heat transfer. Passing through the evaporator tubes, the boiling refrigerant actively absorbs heat from the air blowing over the outer finned surface of the tubes. The air is cooled and the fan 10 is supplied to the car interior.

The elements of the air conditioning system are interconnected by pipelines into a single hermetic circuit. The pipelines are made of aluminum alloy. To connect the moving elements of the system, pipelines in some sections are equipped with flexible inserts made of synthetic materials. At the joints individual elements The system is fitted with O-rings made of neoprene. The pipelines also have two service valves 4 and 9 for connecting diagnostic and refueling equipment. The valves are closed with threaded caps to protect against dirt.

Rice. 12.3. circuit diagram air conditioning systems: 1 - combined pressure sensor; 2 - section of the high pressure pipeline; 3 - receiver-drier; 4 - service valve of the high pressure line; 5 - condenser; 6 - fan of the condenser and radiator of the cooling system; 7 - air conditioner compressor; 8 - section of the low pressure pipeline; 9 - service valve of the low pressure line; 10 - heater fan; 11 - evaporator; 12 - thermostatic valve

It is forbidden to press the spools of the service valves in order to check the presence of refrigerant in the system!

Pressure sensor 1 combined type installed on the section of the high pressure pipeline in the engine compartment. The sensor forcibly turns off the air conditioning compressor when the system is depressurized (pressure is less than 0.17 MPa, or 1.7 kgf / cm2 and in the event of an emergency increase in pressure in the system)

system (pressure is more than 2.5 MPa, or 25 kgf/cm2 in order to protect the compressor from overloads. At a pressure of 1.7 MPa (17 kgf/cm?), the sensor turns on the power circuit of the fan 6 of the engine cooling radiator, resulting in improved heat transfer in condenser and the pressure in the air conditioning system decreases.

The system is charged with R 134a refrigerant. Special oil has been added to the refrigerant to lubricate the compressor.

Notes
When the air passing through the evaporator is cooled, the water vapor contained in it condenses. Condensate is drained through the drain tube under the bottom of the car. If the ambient humidity is high, a puddle of water may form under the vehicle - this indirect sign the condition of the air conditioning system.

In connection with specific features repair of the air conditioning system (see warning above), this subsection describes only the work on removing and installing the control unit for the ventilation, heating and air conditioning system, since the removal of other elements of the heating and air conditioning unit (including the heater radiator) requires complete removal node from the car with depressurization of the air conditioning system.

Replacing the filter of the air entering the passenger compartment is a routine maintenance work and is described in Sec. 4 "Maintenance" (see "Replacing the cabin filter ventilation systems, heating

And conditioning”, p. 81).
