Each car has air conditioning, which is the basis for any climate control system. It filters the air, makes it warmer or cooler depending on weather conditions. Accordingly, without it, the driver and passengers would have been much harder. However, at the same time, many people do not even think about the fact that air conditioning is not a perpetual motion machine, and you also need to monitor it, handle it carefully, and also periodically refuel. You can entrust this work to specialists at the service station, or you can do this 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 buying equipment for refueling autoconditioners, you need to deal directly with the process of working with such a device. Many people use air conditioning, but they don’t even think about how it works, what happens inside, what processes allow the air, for example, to get colder. All this you definitely need to know if you want to independently refuel your air conditioner.
In general, an air conditioning system consists of a large number of parts, but among them it is worth highlighting three main parts - this is an evaporator, compressor and condenser. A refrigerant called freon is constantly circulating throughout the system. In the process, it turns into cold gas, due to which cooling occurs. Therefore, if you purchase equipment for refueling automobile air conditioners, it will not be so difficult for you to make the refueling process yourself, since the system itself is not something unbelievable.
When to refuel?
But when does the moment come when you will need to use 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 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 refrigerant.
If you have a completely new air conditioner, then initially the approximate amount of annual leakage is about fifteen percent. And this means that refueling must be done at least once every three years. Moreover, pay attention to the fact that over time, the air conditioner may wear out and refrigerant will need to be replaced more often. In any case, you will need equipment for refueling and repairing air conditioners.
Urgent reasons for refueling and repair
Naturally, scheduled refueling is a matter of course that no one should forget about. But at the same time, you should understand that there are cases when you do not have to wait three years, and then an unscheduled refueling of car air conditioners is carried out urgently. You must have the equipment for this so that you can carry out this action at any time. The reasons for this may be various external and internal signs. The most common among them are leaks in pipe joints, their damage, as well as the presence of corrosive traces on the capacitor. In this case, you need to either immediately contact the service station, or deal with it yourself.
Equipment
First of all, you need to remember that the process is universal, so the refueling of public transport vehicles and personal vehicles will differ only in details, for example, the type of refrigerant. But in general, the process itself and the equipment that is used for it will be the same. Simply put, for this procedure, you will need to get 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 you can conclude whether refueling is needed. Also, hoses and taps that will connect the air conditioner, meteorological station and freon cylinder, which will be discussed later, will be useful to you.
Refrigerant
You will refill your air conditioner with freon, since it is it that circulates inside the system to ensure the operation of your device. However, at the same time, you can buy not pure freon, but its mixture with compressor oil - this will allow not only refueling the air conditioner, but at the same time preventing further wear of the air conditioner, as well as neutralizing already existing signs of wear. Thus, this mixture is not just a refueling for the air conditioner, but also a way to repair it in case of minor malfunctions and damage.
Such mixtures are sold in containers of different sizes - from one hundred milliliters to half a liter, in the second case, of course, you can completely charge your air conditioner and forget about it for another three years if there are no signs of an urgent need for repair.
Refueling 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 need to connect a cylinder with a refrigerant to the device for filling and measuring and start gradual injection into the system, while monitoring the performance of the meteorological station. The fact is that there is a possibility that a refueling will occur, and this can become a real threat to your car, which in the end can cause serious problems.
Indicators
To understand whether you need to refuel, and when to stop the refueling process, you need to know what kind of pressure is optimal in the air conditioner - for this you will need equipment to refuel the air conditioners. The normal level is considered to be from 1.7 to 3 bar - on factory devices ready for use, this zone will be highlighted in green or blue. If the indicator is below 1.7 - you need refueling, and if above 3 - there was a refueling, and you need to take appropriate measures so that your car does not suffer from this.
