Introduction to the main components of the car air conditioner to keep better
To keep the air conditioner better, first get acquainted with its main components:
- Car Cooler Compressor: The heart of the system that compresses refrigerant gas.
- Condenser: Transfer the heat of the gas.
- Evapctor: It produces coolness and sends into the cabin.
- Refrigerant gas (cooler gas): A material that performs the cooling process.
- Cabin and Fans Filter: To clean and circulate the air.
۱۰ common mistake about car air conditioner you don’t know
Over the years, there have been misconceptions between drivers and misconceptions about the car cooler, some of which are rooted in old and outdated experiences, while others are just a misconception of reality. So many drivers cannot use the air conditioner properly.
1- “Using the Cooler Crash”
Reality: Turning the air conditioner puts more pressure on the engine and increases a little fuel consumption, but if the system is healthy, it will not damage the engine.
2- “We have to charge the cooler gas every year”
Reality: Cooler gas is not consumed. If the system is healthy, it will last for years. An annual charging without leakage is just an extra spending.
3- “Put the fan round on the last grade for more coolness”
Reality: Increasing fan round only makes more noise and increases the pressure on the fan, while cooling depends on the health of the compressor.
4- “turn off the air conditioner in traffic”
Reality: Healthy cooler can even lower temperatures in traffic, it is not necessary to turn it off.
5. “Continuous turn on and off for saving”
Reality: This will put double pressure on the compressor. It is best to put the air conditioner on a constant temperature.
6. “Using Car Cooler Increase Fuel Consumption”
Reality: Yes, using the air conditioner increases fuel consumption, but this increase is not that great. Typical passenger cars: They consume between 2.5 to one liter of gasoline per 2 kilometers, which means that if your car normally consumes 2 liters per kilometer, the air conditioner may reach 1.2 or even 2 liters. In urban driving and traffic, increased consumption may reach 5 % to 5 %, and if you drive on a steady road, consumption increases between 5 and 7 percent.
7. “Using Cooler is not an economic car”
Reality: Suppose your car has 2 liters per kilometer without a cooler. If you turn on the air conditioner and increase the consumption of 2 %:
No air conditioner: 2 liters 1,5 Toman = 1,5 Toman
With cooler: 4.3 liters × ۲ ۱۰ ۱۰ ۱۰ ۱۰ ۱۰ ۱۰ ۱۰ ۱۰ ۱۰ ۱۰ ۱۰ ۱۰۰ ۲۰۱۷
That is, only about 2 kilometers of driving will cost about 2.5 USD.
4 wrong habits to use a car air conditioner that will reduce life
Now that you are familiar with the seven common mistakes about the car air conditioner, you should no longer neglect the tips of keeping the air conditioner like amateur drivers. Indeed, a few wrong habits make the cooler system shorten and the cost of repairing your hand.
1- Using the cooler without initial ventilation
When the car is under the sun, drag the glass down before the air conditioner is turned on to get out of the hot air.
2- Disregard for replacing the car’s cabin filter
The dirty filter reduces air flow and pressure on the compressor.
3- Parking the car in the direct sunshine
The higher the temperature in the car, the more the air conditioner needs to work. Using shade can reduce pressure.
4- Avoid annual cooler service
The annual service causes small problems to be resolved before serious failure.
Professional maintenance tips for car cooler to extend life and efficiency
- Turn on the air conditioner in the winter as well: Even in cold weather, turn the fish once so that the gaskets do not dry.
