How to fill the air conditioner in the car with your own hands? How often to fill the air conditioner in the car? Where can I fill the air conditioner in the car?
Auto-conditioner - today it is not just a luxury,and the necessary device of the vehicle, which is responsible for the favorable microclimate in the cabin. Virtually all modern models of cars are equipped, if not climate-controlled, then conventional air-conditioning. Otherwise, you can install this system additionally, because in hot and stuffy weather the driver and passengers without such a device move around in the vehicle is quite difficult.
A competent car owner not only needs to know,how to clean this device, but also how to refuel the air conditioner in the car. To do this, he must understand the main parts and mechanisms of the system, own techniques and methods that would prevent contamination and damage to this electronic device of the car, and independently solve these problems.
What is the air conditioner in the car for?
To create a comfortable state of the driver andpassengers in the car, many manufacturers install additional systems. They are included in the main parts and mechanisms of the vehicle. To them it is necessary to carry the air-conditioning system. It is presented by an electronic device - air conditioner, which works with the engine on and provides a comfortable driver's condition during the heat in the summer. This allows you to drive the vehicle without problems. In addition, the climate system:
- actively protects the interior of the vehicle from getting inside odors;
- maintains the optimal moisture regime in the vehicle.
Can I service it myself?
With such a system it is fairly easy to work. For this, it is necessary to familiarize yourself with the relevant instruction. It shows general information about the use of the air conditioner, technical parameters, cleaning methods, as well as information on how often it is necessary to refuel the air conditioner in the car. Typically, these instructions highlight general information. And many car enthusiasts are concerned about how to refuel the air conditioner in the car with their own hands, because later it will save on servicing the vehicle in services.
Before you understand the intricacies of such an operation, it is necessary to understand how this device functions in general.
Principle of operation
In terms of its design features, auto-air conditioning is practically the same as an ordinary refrigerator. The difference is only in size.
The main parts and mechanisms of the system include:
- compressor;
- capacitor;
- evaporator;
- valve;
- control;
- highway.
The system is based on refrigerant - freon. The basic principle of work is that freon moves along a closed contour in the form of lines connected between the elements of the system. In one direction, it moves under great pressure, and in the other - under low pressure. The pressure creates a compressor that is started from the engine. From here, along the highway of high pressure, Freon is sent to the condenser. Here the gas becomes liquid and condenses. So he continues to move along the same line to the control valve (adjusting the supply of liquid Freon to the evaporator). Heat from the car's interior goes away as the mechanism passes the liquid refrigerant to the evaporator. With the help of the mechanism, freon is sprayed and then fed to the evaporator. There it becomes gas again and absorbs heat. In this form, the refrigerant is fed to the compressor already along the low pressure line and the cycle is repeated.
Why refuel the air conditioner in the car
The fact is that over time, freon flows outfrom the system. On average, with normal working capacity, this proportion is at least 15% of the total. How often to fill the air conditioner in the car? It needs its timely replenishment in the system every three years. In the event that there is a deformation of the nozzles and joints, it is necessary to fill the air conditioner in the machine as necessary. As a result of a complete or partial loss of the substance, the operation of the system is disrupted, which can lead to an expensive repair of the device.
The equipment for refueling of the conditioner
The car owner should familiarize himself with the methods andways to determine the leakage of Freon from the system. If a breakdown of the climate system has been diagnosed, timely and prompt action should be taken to replenish the volume of Freon with complete or partial replacement of unusable elements of the device.
Previously, the following types of Freon: R12 (1992) and R134a. In order to correctly choose the appropriate refrigerant number, you need to look under the hood, there, as a rule, can contain such information. If there are no such notations, it is worth familiarizing yourself with the instruction of the filling solution or the data on the fittings of the system.
Car enthusiast should know how to refuelair conditioning in the car. To do this, you need to familiarize yourself with a certain algorithm for performing these actions and correctly pick up tools for carrying out the work. For refueling you need:
- Cylinder or container with refrigerant.
- The metrological station.
- Pipe with ferrules.
- Adapter.
Refilling the air conditioner with your own hands
The owner of the vehicle must clearlyrepresent the algorithm of operation and know how often to fill the air conditioner in the car. For this, it is necessary to study the appropriate instruction. Refueling is as follows:
- It is necessary to take a prepared cylinder or container with Freon and connect the adapter with a crane.
- Connect the pipeline, and its other endattach to the exit of the metrological station, which in turn clings to a different pipeline. After this, the device, with which you can fill the air conditioner in the car, is considered assembled.
Nuances of work that are worth considering
Before carrying out refueling it is necessary to maketemperature calibration of the system (metrological station). The calibrator is set to a temperature equal to the ambient temperature. The system then connects to the low-pressure connection of the low pressure line, not the high one. The first highway has a larger diameter than the second one. After selecting the appropriate nozzle, remove the protective cover and clean the surface of the union. Then the pipeline intended for refueling should be connected to the union. Turn on the engine and refuel at 1500 revolutions. Next, turn on the air conditioner at full capacity. Take the balloon with the substance, turn it over and unscrew the adapter tap. Freon will begin to migrate to the system. Here it is necessary to monitor the pressure (not more than 285 kPa). The refrigerant is supplied until cold air enters the ducts. It is necessary to wait until the temperature drops to 8 degrees and then stop the flow. The correctness of the work done will be said to be the absence of bubbles on the filter-drier. This can be seen through a special viewing window.
Detection of refrigerant leaks and how to eliminate them
The owner of the vehicle should not knowonly about where to refuel the air conditioner in the car, but also about how to identify and independently repair the failure of this device. Do not rely on professional auto mechanics. Because the situation is different, and the service center, where you can fill the air conditioner in the car, can be far away. Timely repairs will prevent the system from shutting down. In order to diagnose the refrigerant leakage in time:
- It is necessary to purchase and use a mechanism-dilator in the air of freon.
- When refueling the air conditioner, add the ultraviolet dye to the coolant.
Before refueling the air conditioner in the car,It is necessary to clean the cavities of the air conditioning and heating radiators. It will require the use of a special foam and a vacuum system that removes air from the system. It is also necessary to lubricate all the main parts and mechanisms of the device by refilling freon with oil. The oil is poured into the compressor separately.
In order to correctly use the systemconditioning, the car owner must understand its main parts and principle of operation, learn to determine the leakage of refrigerant and choose the appropriate ways to eliminate it.
