I want you to picture yourself in this scenario. It is a hot day. You get out of bed and jump in the shower and get ready for work. Ladies you spend half an hour carefully applying your make up and styling you hair in order to look your best for the day ahead. You gobble down your breakfast in record time, fly down the stairs and out the door juggling your briefcase in one hand and the keys in the other. You open up the car door and are met with a rush of hot air trying its hardest to escape the record high temperature in the glasshouse that has become your car. You start the ignition and drive to work sweating profusely while trying to stick your face in the breeze out the window mimicking the action of your loved pooch. You arrive at work with a drenched shirt and your near perfect hair stuck to the make up that is now running down your face. Guys just take out the make up part and it could easily be you.
Now I want you to place yourself in the same scenario but you start the ignition and flick on the automotive air conditioning instead. Rather than turning into the melting wicked witch of the west in The Wizard of Oz, you arrive cool, calm and collected at work ready to tackle any problem thrown your way. You no longer dread the peak hour stand still but delight in your improved driving experience.
While some may think that this is somewhat exaggerated, it really
is not. Automotive air conditioning systems act to cool your car in two ways. Firstly they take hot air from the car cabin and remove it to the atmosphere. Secondly through the use of the compressor, condenser, receiver-drier, expansion valve and evaporator, they supply inside the car with cooled air. Basically the compressor squashes a refrigerant gas producing a hot gas in the process. This travels to the condenser. In the condenser as it moves through a series of coils, heat is lost and the remaining gas turns into a liquid. This liquid moves through to the receiver-drier, or accumulator, depending on car make. This part of the air conditioning system ensures only the liquid portion continues the journey to the expansion valve. It is here that the liquid flow onto the evaporator is controlled. At the evaporator the liquid is turned back to cool air, which then flows into your car.
The outcome for the above process is to provide the driver and passengers with a comfortable temperature inside the car despite the outside weather conditions. On a hot and humid day you can set the temperature to remain a constant 180C much more pleasant than temperatures in the high thirties or forties that a car can reach when sitting in the sun.
It also means that you wont stick to the car seats, burn your hand on the steering wheel, gear stick knob or belt buckle if you use the automotive air conditioning to cool everything down before you proceed on your journey. They certainly do improve your driving experience.
