large number of car owners who have a system componenthood of the car, with the onset of heat in a hurry to turn it on.But only some of them are successful.It's time to worry about the 'health' of the air conditioner once retreating cold.His inoperable determine is quite simple: if, after inclusion of a button on the
But ahead of time do not worry: before repairing the air conditioner must run diagnostics, open the bonnet and carefully inspect all air conditioning pipes to find the leak of Freon.If you find on metal tubes oily discharge, it means that Freon leaked, and there was an automatic shutdown of the compressor.
in that the refrigerant flows out of the system, blame is usually dangerous vibration of the engine.Of course, all the tubes in car air conditioners have their own adapters - rubber hoses that are characterized by high pressure, with clamps which sometimes leaks out freon.To understand which parts need to be replaced, and which are suitable for further use, you have to pump freon.
situation when you need to replace the failed air conditioning compressor, it is usually related to negligence or improper installation and maintenance of automotive air conditioner.Often, customer service after discovering darkening insulation or refrigerant leakage limited installation on liquid pipe filter, refueling or removal of the air conditioner leaks, although at this time need drastic measures to repair air conditioning compressor.
necessity of saving the compressor occurs in such cases: in contact with moisture in the refrigerant circuit or when the refrigerant circuit loses tightness.Extend the life of the air conditioner will help emergency resuscitation.To wash the compressor is customary to use Freon R-113, R-11 or carbon tetrachloride.Washing is carried out in two stages.
You must first evacuate the refrigerant using evacuate the cylinder.First complete flushing until a clear liquid state, which is drained from the compressor.Thereafter, the compressor should be filled with a mixture consisting of half butter and half of the washing liquid, and include a compressor for 10-15 minutes to work.Then pour this mixture and, if necessary, carry out a flushing until the complete removal of the oil from the compressor bad.
Evacuate the compressor to produce a complete removal from the unit a washing fluid.After this is take the air conditioning compressor oil dressing.Remember, the refrigeration oils are highly hygroscopic and can easily absorb moisture from the air, thus deteriorating the properties of the oil.To prevent this, you need to limit contact to a minimum oil and air.Therefore it is necessary to purge the compressor after refueling gaseous refrigerant or dry nitrogen, and shut him up connections with plugs.
One of the main components of automobile air conditioner, as you already understood, is a compressor.Regardless of the type of structure in the compressor includes an electromagnetic clutch disconnect it from the drive pulley.Keep in mind that different types of couplings made appropriate use oil to lubricate the mechanism.
Regarding the replacement of the air conditioning clutch, many motorists are used to accomplish this on their own.To diagnose the malfunction of this unit, you need to understand the process of its proper operation.In operation serviceable clutch rotates continuously thanks belt.At the beginning of the coupling is heard a little click that dates its grip, and then it moves in a circle.
If the air conditioning unit is defective and needs repair coupling air conditioner, then there is the following: while rotating the sleeve heard noises that indicate damage to the bearing, there is a smell of burning in the air.If you do not hear the click clutch engagement when the air conditioner, it is not in it.
fault diagnosis in any case be made only with the help of special equipment to repair station.The big problem is related to the malfunction, when the air conditioning compressor only simulates the operation of the clutch, which is moving at the same time freely.At the same time you hear a click, but the interior of the vehicle is not filled with cold air.
glad that couplings are reasonably long life due to the peculiarities of their structure.The main thing to notice malfunction of the unit to avoid extra costs.And she buy a working clutch is not difficult.
Repair Radiator Repair Radiator
automobile air conditioner decided to carry out spraying or using argon arc welding.After the repair work is necessary to make the leak test pressure which reaches 20 atm.To repair the radiator automobile air conditioner, it should be removed from the machine.
worth noting that the radiator repair is considered appropriate only in cases where their business has not made corrosion, for example, after at little mechanical damage, or after a light crash.In a situation of depressurization of automobile air conditioner radiator due to corrosion, it is necessary to make a replacement.
price of the original radiator and air conditioner repair, respectively, the price for some cars up to several hundred euros.In this case, you can replace the radiator after market unit of European quality.You can also set a universal spare part with some alterations tubes.
Repair pipes and hoses
Repair pipes and hoses car air conditioner eliminates defects arising in the air cooling system, and to ensure its resistance to high pressure of the refrigerant.Many models of cars assembled in such a way that the hoses to the compressor inlet, pass near the exhaust manifold, and this in turn triggers their gradual drying, cracking and burning.
In winter can clog hoses and tubes, when the dirt fills the space between the engine cooling radiators and automobile air conditioners.Many tubes accumulate contaminants that clog the highways and prevent good circulation of the coolant, mixed with moisture.
The structure of aluminum, of which the automotive air conditioning pipes, affect aggressive environmental factors.Lead to the destruction of parts changes in temperature, humidity and exposure to chemicals.The mixture of hazardous substances can accumulate in the aluminum tubes and contribute to their oxidation and rotting.
Mobility system components and assemblies in conjunction with the vibration load causes the destruction of the circuit, formed from non-plastic elements.Due to the emergency, driving on bumpy roads or incorrect installation, hoses or tubes are ground or twisted mechanically.An additional factor - fissuring and aging O-rings and rubber gaskets.
If the repair conditioner pipes and hoses not conduct a timely, then such failure will trigger the compressor depressurization.If the machine is operated with damaged hoses and pipes, oil drains, expansion valve and compressor corrode.This leads to clogging of the climate system particles compression rings.
depending on the fault localization and level of destruction of the damaged parts of the system are carried out such work related to repair the air conditioner hoses and tubes: the replacement of O-rings, flushing the cooling air in the car, torn crimping hose, restore the full integrity of the tube with argon welding, replacementtube or hose completely.
most common cause of failure of automobile air conditioner performs a leak of Freon, which is a drop in the level of refrigerant in the system that can cause failure of the compressor, the price of which reaches half the cost of the device.Leaking refrigerant can be normalized or caused by poor installation.For someone leaked brings danger because freon classified as inert gases, non-toxic, no odor and color.
However refrigerant used in car air-conditioners, heavier than air, and therefore displaces the air and accumulates in the room, as well as highlights phosgene, which is dangerous when exposed to flames.Therefore, in case of detection of signs of leak of Freon should stop using and in a timely manner to eliminate the system component malfunction.
Car air conditioners - a mural chiller, the elements of which are connected by threaded Refrigerant.When exposed to temperature changes and vibration properties change of seals, whereby the freon evaporates gradually from the system.That is why the car air conditioner must be periodically refilled.
on the new car you need to top up the coolant every two years, 5-7 years and increases the leakage rate requires refueling every one year, even if there are no obvious defects.All elements of the system component made to oil, which is added to the coolant, and is associated with the recommendations of the air conditioner in the car in winter once a month for ten minutes.
Timely repair of automobile air conditioner will save your nerves and health.Agree that endless traffic jams, held in the heat, pretty exhausting.A cool inside the car is the result of timely maintenance, refueling and repair of air conditioning.
