To say that most people in Buda, Texas wouldn’t want to get in their car without a working air conditioning system would be an understatement. This is particularly true as we head into the summer months and the weather really starts heating up. It’s absolutely essential to make sure your car’s A/C system is ready to start blasting that cold air!
The experts at Christian Brothers Automotive Buda are going to talk about the five parts that make up your car’s A/C system today.
The most essential component of any air conditioning system is the compressor. Your nice, cool air depends on it! The four main functions that your vehicle’s compressor carries out include:
- Pressurizing the refrigerant to cool the air
- Sensing temperature changes inside and outside your car
- Monitoring and controlling temperature output
- Moving air to the condenser
Your vehicle’s A/C condenser is usually located in the front of the radiator, giving it the nickname of the mini-radiator. When the compressor is pressurizing the refrigerant, the condenser works to reduce the temperature and pressure of hot gasses coming from the refrigerant. In addition, the condenser is also responsible for moving the cooled liquid refrigerant to the receiver/dryer or accumulator.
Receiver/Dryer or Accumulator
Whether or not you have receiver/dryer or accumulator depends on the model of your vehicle. A receiver/dryer is present in vehicles that have a thermal expansion valve. An accumulator, on the other hand, is found in vehicles that have an orifice tube.
The receiver/dryer works to separate gas from liquid. The compressor can be ruined if any liquid gets in. That’s because a compressor isn’t designed for liquids, just gasses. This part also takes out moisture using a desiccant. Desiccants can be compared to the small, bead-filled packet you find in packaging for new electronics. Finally, there are also filters that protect the A/C system from contaminants.
The accumulator is responsible for monitoring and controlling the amount of refrigerant that goes into the evaporator. It also stores excess refrigerant, filters debris and removes moisture.
Thermal Expansion Valve or Orifice Tube
As stated previously, cars with a thermal expansion valve utilize a receiver/dryer while a vehicle with an orifice tube utilizes an accumulator. Regardless, the Thermal Expansion Valve or Orifice Tube should be located between the condenser and evaporator. Together, they monitor the amount of pressure and temperature of your A/C system and calculate the exact amount of refrigerant that can safely go into the evaporator.
Another part that’s crucial if you want cold, refreshing air hitting your face is the evaporator. You’ll find this component right behind the dashboard. It’s in charge of cooling the air with the refrigerant before it is blown into the cabin of your vehicle.
It’s true you A/C also utilizes of many other hoses and refrigerant charging ports, but the five parts mentioned here do the heavy lifting.
