Car air conditioner: principle of operation and refueling
The principle of heat exchange is the basis for the long-term service life of the air conditioner. Part of the power of the internal combustion engine is directly used to operate the air conditioning system. How? Selecting from the crankshaft using a drive belt. The procedure itself takes place with the help of specialized equipment, which helps to control the pressure in the system and the volume of the charged refrigerant (freon). It is better not to repeat this at home, but for quality work it is better to turn to specialists.
Advantages and disadvantages
- Cooling and heating mode
In hot and cold weather, the greatest advantage of air conditioning is the creation of optimal conditions while driving. In the summer, the driver will help cool the interior, and in the winter, the air conditioner will get rid of the fogged up windows.
- Working together with climate control
Maintaining the set temperature in the cabin, the presence of a soft blowing mode. A particularly nice feature for those with small children.
- Microbial reproduction
Pathogenic organisms can settle and multiply in the evaporator, which create unfavorable conditions for health. Their presence can be determined quite simply – an unpleasant smell is felt in the cabin.
- Increase in fuel consumption
Typically, an air conditioner needs about 10 liters. with., which is especially felt at high speeds.
Automotive air conditioners are a whole system that consists of several main components. Today we will talk about the most necessary – the compressor.
It is the main element for the entire device. The main property is the pumping of refrigerant (freon) through all pipelines and highways.
The mechanism draws freon vapor from the evaporator and sends the refrigerant to the condenser. It is he who separates the high and low pressure circuits.
When is refueling required?
Typically, refueling is required 2-3 times a year in a car older than 6 years, and annually more than 6.
However, there are “alarm bells” that make you turn for unscheduled diagnostics. Symptoms of such malfunctions:
- slight cooling of the air in the cabin;
- cold air supply is intermittent;
- strange sounds at work;
- long-term temperature change;
- the presence of an unpleasant odor.
