So many times your air conditioner basically saved your life during summer rush hours, but have you ever wondered how the whole system works? Your car's air conditioner operates the same way as the air conditioner in a building, but on a smaller scale.
As the name suggests, it conditions the air by cooling it down or warming it up, while reducing the humidity and moisture content. Your car gets less miles per gallon each time you turn on the AC because it takes power from the engine to run the air conditioner for a car.
The first automobile manufacturer to offer an air con in a car was Packard, way back in 1939. It was a large and bulky system which took up lots of trunk space and it didn't come with that many options.
Later on, in the late twentieth century, car ACs grew in popularity as they became much cheaper to produce and install on the assembly line. Nowadays, it's almost unimaginable to purchase a new car that doesn't have one.
Your car's air conditioner relies on a fairly simple process called the refrigeration cycle.
The refrigerant in the form of a gas vapor, along with the lubricant oil, enters the gas compressor from the evaporator. The compressor compresses the refrigerant to a higher pressure, raising its temperature in the process.
Compressed and heated, the refrigerant then goes through the condenser, where it loses heat and turns into liquid.
The next step is to route the refrigerant through the receiver-drier, which dehydrates it and filters out any water and solid particles. After that, a thermal expansion valve reduces its pressure which leads to flash evaporation and further cooling off.
Finally, the refrigerant passes through the evaporator. It is here that heat transfer occurs between the cooled refrigerant and hot air. As a result, the air is cooled down and the refrigerant heats up to become a vapor again. The cooled air goes through an air filter before it gets blown into the car cabin.
The electronic regulatory system responds to the driver's preferences and by means of a heater matrix.
The cycle is complete when the refrigerant vapor returns to the compressor, so it can restart the cycle.
Now that you're familiar with the way your car air conditioner works, you need to know how to keep it running smoothly.
If you notice that your car air conditioner doesn't keep you cold or warm enough, or if you notice a strange odor coming out of it, it's time to visit a professional maintenance and service shop.
At United Tires, we always perform a thorough investigation. First off, we check for refrigerant leaks and faulty parts.
If there's a leak in a hose, you will gradually lose refrigerant which isn't good for your car and certainly not for the environment.
This is a simple job of replacing a faulty hose, refilling your system with new refrigerant, and re- pressurizing the system according to the manufacturer's specifications.
A car's air conditioner needs to be checked every two years. If you're not sure, give one of our service technicians a call and make arrangements for a proper checkup to keep your car AC running smooth.
