How to fill the air conditioner in the car with your own hands? How often do I 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, but the necessary device of a vehicle that is responsible for a 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 to move in a 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 eliminate these malfunctions.

What is the air conditioner in the car for?

To create a comfortable state of the driver and passengers 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 an air-conditioning system. It is presented by an electronic device - air conditioner, which works when the engine is on and provides a comfortable state of the driver during the heat in the summer. This allows you to drive the vehicle without problems. In addition, the climate system:

• Actively protects the vehicle interior against the ingress of foreign smells;
• Maintains the optimum 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 care 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, you need to understand how this device functions at all.

Principle of operation

According to 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 loop 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 (regulating 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 out of the system. On average, with normal working capacity, this share is at least 15% of the total. How often do I 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 and methods for determining the leakage of Freon from the system. If a breakdown of the climate system has been diagnosed, it is necessary to take timely and promptly all measures to fill the volume of Freon with complete or partial replacement of unusable elements of the device.

Previously, the following types of freon were used: 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, then it is worth familiarizing yourself with the instructions of the filling solution or the data on the fittings of the system.

The car enthusiast should know how to fill the air conditioner in the car with their own hands. 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 filling, you will need:

1. Cylinder or container with refrigerant.
2. The metrological station.
3. Pipe with ferrules.
4. Adapter.

Refilling the air conditioner with your own hands

The owner of the vehicle should clearly represent the algorithm of operation and know how often to fill the air conditioner in the car. For this, it is necessary to study the relevant instruction. Refueling is as follows:

1. It is necessary to take a prepared cylinder or container with freon and connect the adapter with a crane.
2. Connect the pipeline, and connect its other end to the exit of the metrological station, which in turn clings to a different pipeline. After that, the device, with which you can fill the air conditioner in the car, is considered assembled.

Nuances of work that are worth considering

Before filling it is necessary to make the temperature calibration of the system (metrological station). A temperature equal to the ambient temperature is set on the calibrator. The system then connects to the low-pressure fuel filler fitting, not the high one. The first highway has a larger diameter than the second. 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 performed will be said to be the absence of bubbles on the filter-drier. This can be seen through a special viewing window.

Detecting refrigerant leaks and how to eliminate them

The owner of the vehicle should know not only about where to fill the air conditioner in the car, but also about how to identify and repair the device itself. Do not rely on professional auto mechanics. After all, 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 shutdown of the system. In order to diagnose a refrigerant leakage in time:

1. It is necessary to purchase and use a mechanism-dilator in the air of freon.
2. 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. Also it is 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 properly use the air-conditioning system, the car owner must understand its main parts and the operating principle, learn to determine the leakage of refrigerant and choose the appropriate ways to eliminate it.
