The Porsche A/C system has five parts – the compressor, condenser, accumulator, thermal expansion valve and the evaporator. All of these components must function effectively in order to serve the purpose of using the A/C unit, that is, to cool the car. With these various components, expect that every single part has a role to play. Herein, we will tackle the functions of the Porsche A/C evaporator.
What is the Evaporator's Primary Function?
The evaporator is tasked to transform refrigerant from its liquid form to its gaseous counterpart. This can be done by sucking out the liquid refrigerant and allowing it to pass into the vacuum. It is inside this vacuum where the pressure of sucking will suddenly be lessened. As the process goes, heat is drawn out of the liquid refrigerant thereby cooling it. This is essential in preparing it to absorb heat that enters into the system. In principle, the primary function of the evaporator is the exact opposite of the effect of having a condenser in the unit.
From the evaporator, the refrigerant will then be ready to enter the compressor. Inside this part, it will absorb the heat that comes in. Once heated, the refrigerant will then pass through the condenser where it will be transformed back to its liquid state once more. The cooled liquid will then be sucked by the vacuum of the evaporator. The cold gas will be transformed so that it can turn to its gaseous state before entering the compressor.
Where Can You Find the A/C Evaporator?
Many of the A/C evaporators out there are placed inside the passenger compartment, basically just below the instrument panel in a pickup truck. Some SUV's contain two of these evaporators which can be located at the front as well as the back of the vehicle. Front evaporators in these vans can be found under the instrument panel while the rear evaporator can be located on either side of the rear passenger seats. Take note that the location may vary depending on the model and maker of your car.
Other Things You Should Know about the Evaporator
Evaporators are usually made out of aluminum and resemble radiators, only they are smaller than the aforementioned car component. You have to take note that while evaporators contain the refrigerant, radiators, on the other hand, carry with them the coolant in their internal tubes. Evaporators can carry a variety of refrigerant as needed by the car model you are driving.
Are there Problems You Will Encounter with Evaporators?
Just like any other important car component, the A/C evaporator is never without any problems. The simplest yet commonest of all the concerns you will be faced with when it comes to your evaporator is refrigerant leakages. This is typically caused by corrosion that has resulted from corrosion. Corrosion can be brought about by debris, dust, and other foreign objects that get trapped into the evaporator vents. This can further result in a foul, moldy smell inside the car, most particularly obvious when you turn on your car's A/C.
The good news is that you can easily solve this problem. While the only solution to leakage is a replacement, which can mean spending money on your part, it is to be noted that this can be prevented. Maintaining your evaporator will help. Check for debris and dust accumulation on its vents. Replace the evaporator right away at the first sign of leak. Otherwise, your car's A/C unit can get damaged.
