Summer use car, certainly can not do without air conditioning. Then the use of car air-conditioning, the owners should pay attention to what? Today we'll explore the automotive air conditioning problem, of course, also need to prepare OBD diagnostic tool.
Clean the condenser
Air-conditioning system in use for some time, the surface of the condenser will be coated with some foreign body, these foreign bodies blocking the air filter, or floating on the surface of the condenser, which will affect the cooling effect of air conditioning, air conditioning will produce odor, adverse effects on the human body . Should go to the auto repair shop for an inspection of the vehicle air conditioning system, generally they will use Launch X431 IV GX4 Master or Launch X-431 PAD tool to clean the condenser surface of the foreign body, if necessary replace the air filter, in order to maintain a good environment for air conditioning running.
Lack of refrigerant
Lack of air conditioning refrigerant is the main cause of air conditioning refrigeration effect is not good. In normal circumstances, the refrigerant is not reduced, and the main reason is the refrigerant that leaked. Therefore, when check the air conditioning system, to each line carefully check joint, found to have leaked refrigerant situation due to the timely change of relevant components. May require the repair shop at the same time add refrigerant added significantly colored dye, so that when you can easily found leak and timely treatment.
Air conditioning system has numerous piping, duct, these ducts in daily use due to temperature changes, moisture will produce internal hard to avoid. In addition, as the microbes in the air will be left in the air conditioning duct. It's all fueled the growth of bacteria, the bacteria will breed conditioning system odors, serious harm to the health of vehicle occupants. Therefore, regular air-conditioning system for disinfection is still necessary.
Air conditioning additives
The air conditioning compressor additives can increase the compressor, reduce noise, reduce friction, and air conditioning work together to improve the efficiency and extend the life of air conditioning effect. In the auto supply store to buy air conditioning system additive package, the owner can own maintenance on the air conditioning system, the main tool is Autel Maxidiag Elite MD701 or Autel Maxidiag Elite MD703. The main effect of conditioning additives are:
1. Can improve the cooling effect, low air temperature 2-5 ℃.
2. Reduce friction compressor and prolong life.
3. Reduce the air conditioning compressor noise.
4. The fuel savings of about 10%.
