How to take off air conditioning: step-by-step description, features and recommendations

Air conditioners are designed to give people comfort in offices, living quarters, and also in cars. But sometimes these generally reliable devices can fail. Then the dismantling is required. Let's see how to shoot air conditioning in the apartment and in the car.

When you need to dismantle the car

The first is a condenser or radiator. On some models of cars this heat exchanger is so "durable" that it can not work even for one season. This element is constantly exposed to water, dirt, and also reagents from roads.

Infringement of tightness

Depressurization occurs for many reasons, not only because of corrosion. So, in process of deterioration of rubber rings and linings the tightness of system is broken. Also, leaks can provoke hoses. Often, oil seals in the compressor.

Mechanical failure

Most nodes jam, and then the system is depressurized. Compressors can fail because of insufficient cooling of the condenser or because the fan is not working. It also sticks under increased pressure in the system due to Freon overheating. In this case, there is nothing left to do to remove the air conditioner, replace the jammed parts and install it in place.

Other malfunctions

Among the reasons for which it is necessary to remove the split-system, breakdowns in the electrical part, the problems of high-pressure obstruction, breakdown of the electronic unit. How to act in this case?

Dismantling auto-conditioner correctly

Before removing the air conditioner "Priora", you need to know what this system represents. So, AvtoVAZ installs in Prioru the most primitive air conditioners. The unit is a condenser, a compressor, and also a main line.

On AvtoVAZ vehicles, the most frequent malfunction of the air conditioning system is the failure of the electromagnetic clutch. First, the coupling bearing collapses, and then it itself. Among the most likely reasons for the failure of the coupler is the incorrect tension of the drive belt, slippage of the disks. After leaving the bearing standing on the pulley, a backlash is formed, which leads to abrasion of the winding of the coupling. Sometimes the part can jam. The problem can be solved by replacement. Let's see how to remove the air conditioning compressor on the "Prior".

Getting Started

So, first the car is de-energized. For this it is enough to remove the negative terminal with the battery. Then you need to remove freon from the system. For this purpose, a special valve is provided on the cover. After that remove the mudguard of the motor. Then, the accessories belts are dismantled.

Then disconnect the connector from the compressor clutch. Unscrew the mounting bolt of the high-pressure flange to the compressor and remove it. The low-pressure pipeline is also dismantled. The compressor is fixed to the engine and is held by three bolts, they are also unscrewed. Remove the compressor from the bottom.

How to remove the generator "Priora" with air conditioning

Often on this car, there are problems with the generator, but to remove it is not so simple - you need to disassemble half of the car and bleed freon from the air conditioner. Let's see how to dismantle the generator yourself. Unlike the "Prior" without an air conditioner, you need to remove the generator in this case from the bottom. The car is driven to a pit or to a ski lift. Then remove the engine protection, loosen the tension pulley drive belt. Then unscrew the upper bolt, which holds the generator.

Now you need to move down under the car. Here remove the bolts that fix the air conditioning compressor, which is very disturbing. Next, carefully remove the belt, going to the compressor and the generator.

To remove the last node, it is pulled from its seat and taken away towards the battery. So you can access the topmost bolt holding the air conditioner. After unscrewing the last bolt, you can hang the compressor, this is enough to work. He will not fall, and the tubes that go to him have sufficient rigidity. After that, unscrew the bolts holding the generator. Disconnect its terminals and pull the unit down.

How to dismantle an air conditioner condenser

On each car, this part and its installation location has its own peculiarities. Fastening can also be different. Some air conditioner heat exchangers are installed in front of the radiator of the cooling system, others - behind it. Let's see how to remove the radiator of the air conditioner from the car. Often, condensers remove the bottom of the machine - it is much more convenient to work and do not have to disassemble half of the machine. First, remove the motor protection, the grille, and (if necessary) the front bumper. Then it remains to unscrew the fasteners and release the condenser.

Remove the coupling

The coupling or pulley is most often removed to replace the bearing. The fault will manifest itself in the form of a characteristic whistle from the engine compartment. Also the coupling will have a backlash. Let's see how to remove the air conditioning clutch and replace the bearing.

A set of tools for dismantling

For dismantling work you will need a standard set of motorist tools, as well as a jack and a set of Torx screwdrivers. Still need to prepare a chisel for drawing notches on the coupling. And finally, you need a new bearing to replace.

Instructions for removing the coupling

First of all, the jack is placed under the front right wheel, tear off the wheel bolts, lift the wheel. Then the bolts are completely unscrewed, the disk is removed. Then, using a 8 wrench and a screwdriver, remove the fasteners of the mudguard and anther. After that, you will have access to the tension roller of the generator, it should also be unscrewed. With a head on 8, unscrew the fixing bolt holding the coupling and remove its upper cover. Then, remove the snap ring, which holds the pulley on the drive shaft of the compressor, and remove everything together with the bearing. Sometimes the bearing must be knocked out. Replace the bearing and install the coupling in the reverse order.

Split systems

Home air conditioners are dismantled not only because of breakages. Often they are removed to move to another apartment or office, at the time of repair. The split system differs significantly from the car air conditioner, and you need to know how to remove the air conditioner correctly.

Dismantling the wall system

Removing small wall-mounted air conditioners is easy, especially if there is a set of standard tools. So, you need two Swedish keys, a pipe cutter, a manometer, an indicator screwdriver, wrenches and hexahedrons. It is also desirable to have a manometric station available to store freon. Let's see how to remove the outdoor and indoor unit .

The first thing to do is to pump out freon. It is better to pump out the external unit. For this purpose, a manometer is connected to the gas valve. Next, the side panel is dismantled and the supercharger valve is screwed into the hexagon. Within a minute, all Freon will flow into the external unit, and the pressure in the highway will drop. Then the valve is twisted and turned off. After that, with the help of a pipe cutter, the tubes are cut off - it is necessary to withstand 15-20 cm from the nozzle. Tubes are rolled and remove the outer part from the brackets. Then proceed to dismantle the indoor unit. Let's see how to remove the air conditioner from the wall - it's easy. Open the lid of the device, unscrew the fixing elements holding the module, remove the trunk, wrap the ends of the tubes, turn off the electrical wires. It remains only to remove the block from the plate on which it is held. Before removing the air conditioner from the wall completely, carefully remove the fastening of the pipeline and plastic housing.

We remove the channel split system

It is already more difficult to carry out independent dismantling of such equipment - these units have considerable weight. But in addition, they will have to remove their air ducts. To dismantle such air conditioners you need the same set of tools as in the case of a split system. The first stage will be the analysis of air ducts. To do this, remove the grate, remove the air ducts. This is done by detaching them from the inside of the system. The flexible duct is fixed to the clamps. In the case of metal screws are untwisted. Before you remove the air conditioner, you need not forget to pump freon into the external unit.

Removal is carried out on the same principle as when dismantling the home split system. Further loosen the evaporator nuts, remove the freon line and extract the electrical wires. Also disconnect and drain hose. At this stage, the process for dismantling the unit was successfully completed. Then you can take any action related to the repair of the air conditioner, or change it entirely to a new one.

Conclusion

Thus, it is possible to dismantle the air conditioners. Having the experience of working with tools, all operations are easy to do by oneself. . Also note that now there are many masters offering services for dismantling split systems . For private houses, the price of services is about two and a half thousand rubles. For residents of multi-storey houses - from three and higher (depending on the specific floor). In this case, the specialists have all the necessary kit for work with the air conditioning system. . This can save you a lot of time, and you can not bother with studying the device system .
