Shortly speaking

Car air conditioning is an element that increases the comfort of the driver behind the wheel. Interruptions in its operation, weak airflow, noisy operation, or an unpleasant odor from the fans may indicate contamination or damage to the cooling system. First aid for many breakdowns is the replacement of the cabin filter and the disinfection of the evaporator and air conditioner tubes, which you can do yourself with the help of special preparations.

What is a car air conditioner?

An automobile air conditioning system is a system whose main task is to supply cold air to the passenger compartment. The whole process about refrigerant circulation to the individual components of the air conditioning systemin the final stage, the driver feels pleasantly refreshing the body on hot days.

How does a car's air conditioning system work?

It all starts when the factor hits compressorin which, under the action of the clutch, its pressure and temperature increase. From there it goes to tray and is drained and cleaned. In this form, it enters the capacitor, that is, otherwise cooler air conditioning, where the most important part of the process takes place - lowering its temperature and converting it from a gas to a liquid. Later, the liquid goes into Dehumidifierwhere it is separated from contaminants, air and water vapor to pass through expansion valve decompress and cool. Then the refrigerant reaches evaporator and turns back into a low temperature gas. At the final stage, it penetrates FILTER i ventilation system enters the vehicle interior, effectively cooling it. The air from the car is sucked back into the compressor and the whole process starts over.

The most common symptoms of a car air conditioner malfunction

The air conditioner not only keeps you cool on hot days, but also dries the car interior... This is especially important in winter when steam on the windows reduces visibility and jeopardizes the safety of the driver. Sometimes the cooling system does not work properly, which reduces driver comfort. We have compiled a list of the 5 most common symptoms that indicate a malfunctioning air conditioner.

Little or no cooling

If there is little or no cool air flow from the fans after turning on the air conditioner, this may indicate a dirty pollen filter, a clogged dryer, faulty valves, a malfunctioning compressor magnetic clutch, or even a malfunctioning compressor. However, the most common reason for lack of cooling low level of circulating factor in the system. This does not necessarily mean a serious problem right away - this substance is gradually consumed during cooling (about 10-15% per year), so be sure to replenish it regularly. If the refrigerant disappears too quickly, some components may be leaking and require service repair.

Intermittent air conditioner operation

Intermittent operation of an automotive air conditioning system is the most common result. clogging of the cooling system caused by moisture, dirt or rust clogging of individual elements. A complete lack of reaction to the inclusion of cooling ventilation can be a sign driver malfunction... In both cases, the best solution would be to use the services of a professional workshop.

Low airflow from fans

Subtle airflow usually means a clogged cabin filter, which is responsible for cleaning the air inside the car. Clogging it up will not only block the possibility of cold air coming out of the air conditioner, but can also lead to damage to the blower drivewhich will require expensive repairs. The cabin filter should be replaced according to the manufacturer's recommendations, i.e. about once a year or every 15-20 thousand kilometers. Excessive moisture in the passenger compartment and condensation on the windshield can also be a sign of a clogged filter.

Loud operation of the air conditioning system

Strange noises from the air conditioning system are almost always a sign of a serious malfunction in the air conditioning system. Loud work can be the result. V-belt slippage, damage to the outer pulley bearing or even a jammed compressor... Although tensioning a V-belt is not too difficult and expensive, replacing a compressor unfortunately requires a much greater financial investment on the part of the car owner. However, responding quickly to unusual sounds avoids high costs.

Bad smell from fans

An unpleasant smell from the ventilation always indicates contamination of the air conditioning system due to deposits. fungus, mold and germs in the evaporator responsible for the condensation of water vapor. Moisture is an ideal breeding ground for harmful bacteria, so you should regularly disinfect the system - yourself, with the help of special preparations, or in a professional car repair shop. Air conditioning pollution irritant, allergenic and toxic - It is not worth postponing their removal.

Air conditioning also in winter

The most common reason for air conditioner breakdowns is undoubtedly long break in his work... Failure to use the cooling system in winter can lead to corrosion and seizure of the compressor, as well as the development of mold and mildew in the evaporator, which are harmful to the health of the driver. If the car has an unpleasant smell or poor air supply, this should be done as soon as possible. cleanse and refresh.
