Why is air conditioning in a car important?
Air conditioning improves driving comfort. It allows you to keep the interior of your car cool on hot days, helping you stay focused, which ultimately increases driving comfort. It also improves driving safety, as it dries the air inside the car, preventing the windows from fogging up and limiting visibility.
How does the air conditioning system work?
The air conditioning system consists of a compressor, a hose system, and a refrigerator, also known as a condenser, and an evaporator. The air conditioning system is filled with a special substance, which, compressed by the compressor, flows to the evaporator, where it decompresses. During decompression, the agent cools the evaporator and the air created by the fan, and it is sent to the cabin. Then the agent is transferred to the condenser, where it releases the heat transferred by the evaporator. As a result of this continuous process, the evaporator cools and the radiator releases heat into the cabin.
When should the air conditioning system be charged?
In order for the air conditioning system to work efficiently and properly, it should be filled with the right amount of substance specified by the car manufacturer. You will find the corresponding information on the compressor panel or on the label located on the engine compartment. The amount of substance decreases over time due to small leaks in the hoses, compressor, cooler or evaporator. If this is the case, the air conditioning system stops working properly, which poses a danger to the compressor, which must work continuously, but suddenly it is no longer properly lubricated by the oil contained in the substance, and in this case it must be filled with a new amount of substance. During the maintenance process, however, the agent is completely removed from the system, which is subjected to negative pressure to check the tightness of the system, and then refilled with the appropriate amount of oil required to lubricate the compressor.
