What is the difference between climate control and air conditioning in a car
Good things, as you know, you get used to quickly. It seems that Russia is a northern country, but now most of the purchased cars are equipped with air conditioners. If earlier air conditioning was included in the list of options, now for many cars presented for sale at the dealerships of FAVORIT MOTORS Group, it is already included in the basic equipment.
Operating principle
The air conditioner works in the same way as a conventional refrigerator. The sealed system, into which the refrigerant with oil additives is pumped, consists of a compressor, a radiator, and a receiver-drier. In the compressor, the refrigerant is compressed and changes from a gaseous state to a liquid state. It heats up, the temperature decreases only due to air blowing when the car is moving or from the operation of the fan. After passing through the receiver-drier, the refrigerant again passes from a liquid state to a gaseous state and cools down. Cool air enters the car interior.
The air conditioner dries the air: when driving in the rain, it is enough to turn it on and the windows will stop sweating. But excessively dry air adversely affects the health of people in the car: water begins to evaporate from the skin, hair and mucous membranes of the respiratory tract. As a result, it is easier for viruses to enter the body. It is for this reason that colds are common when breathing dry air. Therefore, when driving for a long time in the heat with the air conditioning on, it is necessary to drink water.
Climate control and air conditioning - differences
Unlike a conventional air conditioner, climate control can maintain a predetermined temperature in the passenger compartment. The system includes several temperature sensors and an electronic control unit. It is enough to set the desired value, and after cooling the passenger compartment, the smart electronics will automatically reduce the temperature and airflow intensity.
Dual-zone climate control allows you to set different temperature conditions for the driver and passenger. Business class cars are often equipped with three or four-zone climate control, which creates additional convenience for second-row passengers.
Some minibuses have two air conditioners, because the power of one is not enough to cool a large passenger compartment.
Air conditioner malfunction
Vehicle equipment is constantly subjected to significant loads: constant vibrations and shocks, temperature changes. Aggressive environment - various road chemicals - also negatively affects. Designers do not have the opportunity to use sealed tubes installed in domestic refrigerators in the machine.
The elements of the system are connected by rubber pipes, the tightness gradually disappears. At the same time, the cooling efficiency decreases and, if repairs are not carried out in time, the expensive unit may fail. If you notice that the air conditioner has begun to work worse, immediately contact the technical specialists of FAVORIT MOTORS Group of Companies.
They will determine the places where the tightness is broken. Visually, they are difficult to identify, so the craftsmen add coloring additives to the refrigerant. Highlighting with an ultraviolet flashlight, it is possible to fix problem areas. After restoration of tightness, the system is filled with refrigerant with oil additives.
There may be other reasons for the failure. For example, contamination of the radiator and the system itself. Sometimes coolness does not get enough into the cabin due to a clogged cabin filter. A correct diagnosis can only be made by specialists.
How to Avoid Air Conditioning Colds
Moisture accumulates in the air ducts, and optimal conditions are created for the reproduction of bacteria and fungi. One of the signs is a musty smell. This is not only unpleasant, but also dangerous to health. There is even a special term "legionnaire's disease". He appeared after an incident in 1976 when 130 of the 2000 participants in the congress of the public organization "American Legion" became seriously ill.
The symptoms resembled pneumonia, and 25 people could not be saved. The culprits turned out to be a little-studied at that time bacteria, called legionella, which bred in the hotel's air conditioning system.
As you can see, cleanliness needs to be monitored. It is recommended to carry out disinfection of the air conditioner for preventive purposes approximately once every 1 years. Qualified employees of FAVORIT MOTORS Group of Companies can disinfect the air conditioner as part of scheduled maintenance, such work is especially useful after the winter period.
Doctors do not recommend setting the lowest possible temperature in the heat, no matter how much you would like it. First you need to set 25C and after about 15 minutes lower it by 5 degrees. It is undesirable to direct cold air directly to the face. It is preferable to orient the air duct nozzles up and sideways - in this case, the car interior is cooled evenly, and there is less chance of catching a cold.
Prevention
For proper operation, the air conditioner must be periodically turned on for several minutes - while the entire system is lubricated. The procedure must be done, including in winter. On a number of models, the temperature sensor will not allow the unit to function in the cold, so you can turn it on in a room with a positive temperature. For example, in the underground parking of a shopping center.
It is also important to keep the radiator clean, but it is dangerous to clean it yourself with a high pressure washer - there is a chance of deforming and incapacitating it.
It is better to entrust the service to the specialists of FAVORIT MOTORS Group of Companies!
