To increase the comfort of cars in the summer, factories install cooling devices in cars. These equipments imply a systematic refueling of freon and suitable maintenance. Even if the cooler is working properly, it is necessary to replace the gas if more than a year has passed since the last service (according to the instructions of specialists)
Specificity of the device of air conditioning systems in cars
For the normal functioning of all the components of the moving elements of the compression unit, in addition to freon, special oil is charged into its system. However, the performance of the latter can be greatly reduced due to its mixing with gas (freon is far from durable). Every 2 years, manufacturers recommend car owners to replace freon, which also has its own characteristics. However, not all vehicle owners are aware of these intricacies.
So, in order to prevent environmental pollution for safety reasons, all the exhaust gas must be pumped into special cylinders and in no case should it enter the atmosphere. It should be noted that in service centers, workers often pump exhaust gas from a cylinder into a cooler that is already mixed with oil. In this way, savings occur at the service center.
How is Freon replaced correctly?
At home, car owners do not have the opportunity to replace freon in the compressor with their own hands, since they do not have all the necessary equipment to eliminate the loss of tightness of the entire circuit and determine the pressure in the system and as a whole. This is a very complicated procedure. Therefore, refueling should be carried out in the appropriate services, where specialists are quite responsible for such work and will be able to determine the state of the quality of oil and other technical fluids and, if necessary, replace them.
It should be noted that such a device as a compressor is quite expensive and costs 100 thousand rubles or more. Therefore, car owners should not save on maintenance, where a full-fledged check of the fluid is carried out, and if it is not investigated in a timely manner, it can subsequently lead to the failure of the mechanism. At the same time, it is possible to prevent the appearance of freon leakage (which is a quite costly component) by checking the strength and density of the circuit, as well as pressure.
To eliminate the problem of pumping low-quality depleted freon into the air conditioner, car owners should be in the repair service area, where you can fully monitor the work of specialists and be completely confident in the high-quality work done. For this, there are workshops where manual filling with fresh gas takes place.
Service frequency
Every motorist should be aware that even if the cooling system is working properly, it is still necessary to systematically come to the service center in order to diagnose the operation of the air conditioner, where the freon is also replaced and the quality of the lubricant is simultaneously assessed.
If the cooling system is used daily, the filling should be done once a year, otherwise at least once every two years. When choosing a service center, the car owner must be confident in the professionalism of the employees of the selected car service and have the guarantees that this service offers.
