Each car has air conditioning, which is the basis for any climate control system. It filters the air, making it warmer or cooler depending on the weather. Accordingly, without it, the driver and passengers would have had a much harder time. However, at the same time, many people do not even think about the fact that the air conditioner is not a perpetual motion machine, and it also needs to be monitored, handled carefully, and also periodically refueled. You can entrust this work to specialists at a service station, or you can do this business yourself. But for this you will need equipment for refueling car air conditioners, as well as certain skills and knowledge.

How does air conditioning work?

Before you buy equipment for refueling car air conditioners, you need to deal directly with the very process of operation of such a device. Many people use air conditioning, but at the same time they don’t even think about how it works, what happens inside, what processes allow the air, for example, to become colder. All this you need to know if you want tocharge your air conditioner.

In general, the air conditioning system consists of a large number of parts, but among them it is worth highlighting three main parts - an evaporator, a compressor and a condenser. A refrigerant called freon constantly circulates throughout the system. In the process, it turns into a cold gas, due to which cooling occurs. Therefore, if you purchase equipment for refueling car air conditioners, it will not be so difficult for you to do the refueling process with your own hands, since the system itself is not something incredible.

When to refuel?

But when is the moment when you need to use the equipment to refuel and repair car air conditioners? Installing it is a separate, more complex issue, but first you need to figure out exactly how often the air conditioners in cars require refueling. It’s worth starting with the fact that freon is the most important thing on which the operation of the entire system depends. Accordingly, it is necessary to focus on it, since over time there is a gradual leakage of the refrigerant.

If you have a brand new air conditioner, the initial approximate annual leakage is about fifteen percent. And this means that refueling must be done at least once every three years. Moreover, please note that over time, the air conditioner may wear out, andthe refrigerant will need to be changed more frequently. In any case, you will need equipment for refueling and repairing car air conditioners.

Urgent reasons for refueling and repairs

Of course, scheduled refueling is a self-evident action that no one should forget about. But at the same time, you must understand that there are cases when you don’t have to wait three years, and then unscheduled refueling of auto-conditioners is urgently carried out. You must have the equipment for this so that you can carry out this action at any time. The reasons for this can be various external and internal signs. The most common among them are leaks in pipe connections, damage to them, as well as the presence of corrosive traces on the condenser. In this case, you need to either urgently contact a service station, or deal with it yourself.

Equipment

First of all, you need to remember that the process is universal, so filling public transport and personal car air conditioners will differ only in details, such as the type of refrigerant. But in general, both the process itself and the equipment used for it will be the same. Simply put, to carry out this procedure, you will need to acquire either a ready-made device that will allow you to simultaneously measure and refuel the air conditioner, or certain elements with which you can do it yourself.

Among them, there must be a meteorological station that will allow you to measure the pressure inside the air conditioning system - it is on the basis of the readings of the device that it will be possible to conclude whether refueling is needed. You will also need hoses and taps that will connect the air conditioner, meteorological station and freon cylinder, which will be discussed later.

Refrigerant

You will fill your air conditioner with freon, since it is he who circulates inside the system to ensure the operation of your device. However, at the same time, you can purchase not pure freon, but its mixture with compressor oil - this will allow you not only to fill the air conditioner, but at the same time prevent further wear of the air conditioner, as well as neutralize existing signs of wear. Thus, this mixture is not just a refill for the air conditioner, but also a way to repair it in case of minor malfunctions and damage.

Refilling process

As mentioned earlier, first you have to measure the pressure inside your air conditioner. If it is below a certain level, then you will need refueling. After that you needconnect a refrigerant bottle to the charging and measuring device and start gradually injecting into the system, while monitoring the performance of the meteorological station. The fact is that there is a possibility that refueling will occur, and this can become a real threat to your car, which can eventually cause serious problems.

Indicators

To understand if you need refueling, and also when to stop the refueling process, you need to know exactly what pressure is optimal in the air conditioner - for this you will need equipment for refueling car air conditioners. The normal level is considered to be from 1.7 to 3 bar - on factory-made devices ready for use, this zone will be highlighted in green or blue. If the indicator is below 1.7, you need a refueling, and if it is above 3, a refueling has occurred, and you need to take appropriate measures so that your car does not suffer from this.
