Over time, the efficiency of the car air conditioner can decrease, and the salon has an unpleasant odor. Often, this indicates the need to refuel the system with a harlebont (freon). Understanding the principles of the air conditioner and the first signs of his malfunction will help you consult a specialist in a timely manner and avoid expensive repairs.
Automobile air conditioning is a complex system where oil and refuge (freon) circulate on aluminum tubes. Freon constantly changes its aggregate state - from gaseous to liquid and vice versa - providing cooling of the salon. However, over time, the tightness of the system can be disturbed by vibrations of the car, aging of materials and drying of rubber seals. This leads to a gradual loss of freon. Even in a fully tight system, the freon gradually evaporates. The main signs of reflection of the refrigerant: weak or no cooling. The air conditioner works, but the air is not cooled or not cooled enough. Frequent shutdown of the compressor. Due to the lack of pressure, the system automatically switches off the compressor. Unpleasant smell. There is a musty or other unpleasant odor from the ventilation openings. Extraneous sounds. The hiss or whistle during the operation of the air conditioner can indicate not only the lack of freon, but also about problems with the compressor. If the cooling is worsened, one dressing may not be enough. It may be necessary to diagnose tightness, replace seals or cleanse the system.
In addition to Freon refueling, it is important to clean the ventilation system regularly. It accumulates bacteria and dust that cause unpleasant odor and can be harmful to health, especially for allergies and asthmatics. Cleaning can be combined with dressing. When and how often should the air conditioner be tucked? New cars: the tight system does not require refueling for up to 5-7 years. Older cars: if there are signs of freon insufficiency, the dressing may take about once every 2 years. With slight leaks: Freon is added every 1-3 years. After repair of the system: complete cleaning and air conditioning is required.
If Freon is lost very quickly (faster than a year), it is a alarm. It is necessary to look for and eliminate leakage, because together with the freon comes out the oil, and can also get moisture, which leads to corrosion and breakdowns.
Timely with a freon air conditioner and regular ventilation cleaning is the key to a comfortable climate in the salon and the durable system. At the first signs of deterioration of the air conditioner, consult a professionals to avoid serious and expensive problems.
