Air conditioners are designed to give people comfort in offices, residential premises, as well as in cars. But sometimes these generally reliable devices can fail. Then dismantling is required. Let's see how to remove air conditioning in the apartment and in the car.
When the dismantling of the air conditioner is required
The first out of order is a condenser or radiator.
On some car models, this heat exchanger is so "durable" that it is not able to work out even one season. This element is constantly exposed to water, dirt, and also reagents from roads.
Leakage
Depressurization occurs for many reasons, not only due to corrosion. So, as the rubber rings and gaskets wear, the system’s tightness is broken. Leaks can also provoke hoses. Often, oil seals flow in the compressor.
Mechanical breakdowns
Most often, the nodes are jammed, and then the system is depressurized. Compressors can fail due to insufficient cooling of the condenser or due to an inoperative fan. It also sticks at elevated pressure in the system due to freon overheating. In this case, there is nothing left to do, how to remove the air conditioner, replace jammed parts and reinstall it.
Other malfunctions
Among the reasons why it is necessary to remove the split system, breakdowns in the electrical part, problems of high pressure obstruction, breakdown of the electronic unit. What to do in this case?
We dismantle the air conditioner correctly
Before you remove the Priors air conditioner, you need to know what this system is. So, AvtoVAZ installs the most primitive air conditioners in Priora. The unit is a condenser, compressor, as well as highways.
On AvtoVAZ vehicles, the most common malfunction of an air conditioning system is a breakdown of the electromagnetic clutch. At first, the clutch bearing is destroyed, and then she herself. Among the most probable reasons for the failure of the clutch are the incorrect tension of the drive belt and slippage of the disks. After the bearings exit the standing position, a play forms on the pulley, which leads to abrasion of the clutch winding. Sometimes a part can jam. The problem can be solved by replacement. Let's see how to remove the air conditioning compressor on the Prior.
Getting to work
So, first the car is de-energized. To do this, just remove the negative terminal from the battery. Then you need to bleed freon from the system. There is a special valve on the cover for this. After that, remove the mudguard of the motor. Next, dismantle the belts of auxiliary equipment.
After disconnecting the connector from the compressor clutch. Turn out the fixing bolt of the high pressure flange to the compressor and remove it. A low pressure pipeline is also dismantled. The compressor is fixed to the engine and held by three bolts, they are also unscrewed. It is better to remove the compressor from below.
How to remove a Priory generator with air conditioning
Often there are problems with the generator on this car, but it is not so easy to remove it - you need to disassemble half the car and vent freon from the air conditioner.
Let's see how to do the dismantling of the generator with your own hands. Unlike Prior without an air conditioner, in this case the generator must be removed from below. The car is driven into a pit or onto a lift. Then remove the engine protection, loosen the tension roller of the drive belt. Next, unscrew the upper bolt that holds the generator.
Now you need to move down under the car. Here they remove the bolts that fix the air conditioning compressor, which is very in the way. Next, carefully remove the belt going to the compressor and generator.
To remove the last node, they pull it off its seat and take it away towards the battery. This way you can access the topmost bolt holding the air conditioner. After unscrewing the last bolt, you can hang out 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 characteristics. Fasteners may also vary. Some air conditioning heat exchangers are installed in front of the radiator of the cooling system, while others are behind it. Let's see how to remove the air conditioning radiator from the car.
Often, capacitors are removed from the bottom of the car - it is much more convenient to work and you do not have to disassemble half the car. First remove the motor protection, radiator grill, and also (if necessary) the front bumper. Then it remains to unscrew the fasteners and release the condenser.
Remove the clutch
The clutch or pulley is removed most often to replace the bearing. The malfunction will manifest itself in the form of a characteristic whistle from the engine compartment. Also, the coupling will have play. Let's see how to remove the air conditioner clutch and replace the bearing.
Disassembly tool kit
For dismantling, you will need a standard set of motorist tools, as well as a jack and a set of Torx screwdrivers. You also need to prepare a chisel for applying notches on the coupling. Finally, a new bearing is needed for replacement.
Coupling Removal Instructions
The first step is to install the jack under the front right wheel, tear off the wheel bolts, raise the wheel. Then the bolts are completely unscrewed, the disc is removed. Next, with a key of 8 and a screwdriver, dismantle the fasteners of the mudguard and anther. After that, access to the tension pulley of the generator will appear, it should also be unscrewed. Using an 8-head head, unscrew the fixing bolt holding the coupling and remove its upper cover.
Then dismantle the retaining ring that holds the pulley on the drive shaft of the compressor, and remove everything together with the bearing. Sometimes the bearing needs to be knocked out. Bearing replacement and coupling installation are performed in the reverse order.
Split systems
Home air conditioners are dismantled not only because of breakdowns.
Often they are rented to move to another apartment or office, during the repair. The split system is significantly different 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 not difficult, especially if there is a set of standard tools. So, you need two Swedish wrenches, a pipe cutter, a pressure gauge, an indicator screwdriver, wrenches and hexagons. It is also advisable to have a gauge station available to preserve freon. Let's see how to remove the air conditioner unit, external and internal.
The first step is to pump out freon. It is better to pump into an external unit. For this, a pressure gauge is connected to the gas valve. Next, the side panel is dismantled and the supercharger valve is screwed in with the hexagon. Within a minute, all the freon will flow into the external unit, and the pressure in the line will drop. Then the valve is turned on and off. After that, using a pipe cutter, cut the tubes - you need to withstand 15-20 cm from the fitting. The tubes are rolled and remove the outer part from the brackets.
Next, proceed to the dismantling of 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 fasteners holding the module, remove the line, roll up the ends of the tubes, disconnect 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 fasteners of the pipeline and the plastic case.
We remove the channel split system
It is already more difficult to independently dismantle such equipment - these units have significant weight. But besides this, they will have to remove their air ducts. To dismantle such air conditioners, the same set of tools is needed as in the case of the split system.
The first step will be the analysis of the ducts. To do this, remove the grill, clean the air ducts. This is done by disconnecting them from the inside of the system. A flexible duct is attached to the clamps. In the case of metal, screws are unscrewed. Before you remove the air conditioner, you need to remember to pump freon into the external unit.
Removal is performed according to the same principle as when dismantling a home split system. Next, loosen the nuts of the evaporator, remove the freon line and remove the electrical wires. Also disconnect the drainage hose. At this stage, the process of 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
In this way, air conditioners can be dismantled. Having experience working with tools, all operations are easy to do with your own hands. Also note that now there are many masters offering services for dismantling split systems . For private homes, the price of the service is about two and a half thousand rubles. For residents of multi-storey buildings - from three and above (depending on the specific floor). At the same time, specialists have all the necessary kit for working with the air conditioning system. This can save you a lot of time, and you can not bother with studying the device system .
