Car Air Conditioning
 Almost every new car, truck or SUV bought nowadays might be equipped with air conditioning. It's so ordinary that most people believe that the car is not sold without it. You push the button for air conditioning in your vehicle and cool air stream appears out of the car's vents. It's simple, it's trouble-free, and it's a main advantage. Can you fancy driving to a job interview in Phoenix, Ariz., if there is no air conditioning in your car? When you come to your interview, you might be a sweaty, fetid dirty thing.
Have you ever taken an interest in how the air conditioning in your car functions? If you're similar to the majority of people, you most likely haven't. But we can teach you painlessly. Air conditioning is the procedure by which air is cooled and desiccated. The air conditioning in your vehicle, your house and your office all function the similar way. Even your fridge is, in fact, an air conditioner. While there are a great number of physical bases that define air conditioning, we would like to tell you the most important things. We give details of the common notions of vehicle air conditioning, the parts utilized and what you should to be familiar with to keep your car's A/C system functioning as it should be.
Are you aware of that when you switch on the A/C in your vehicle, additional fuel is spent just to make feel cooler? It's strange to imagine that by burning something it’s getting colder, but it's right.
On the whole, air conditioning mechanisms function on the basis of evaporation and condensation.
Let’s consider an easy illustration of evaporation. Fancy that you're swimming around in your backyard pool on a hot day in summer. The moment you come out of the water, you feel cold. How could it happen? The water on your skin begins to evaporate and it becomes water vapor. And when it evaporates, it takes warmth away from your skin, and you get goose-flesh. It’s really chilly, ha! After that you go inside and pour a large glass of ice-cold lemonade. You taste it and lay it down on a floor beside you. After a couple of minutes, you see that water has gathered on the outside of the glass. This process is known as condensation. The air which is close to the glass gets cooler when it bumps into the cold glass and the water vapor the air is taking condenses into water.
Both of these patterns happen at usual atmospheric pressure. But higher pressures are able also turn a vapor (or a gas) into a water. For instance, if you observe a usual butane cigarette lighter, you can make out fluid substance inside it. But the moment you press down on the button, butane gas gets out. Why? Inside the cigarette lighter the butane is under high pressure, so it is condensed. This high pressure forces the butane to take fluid appearance. The moment the butane gets free and it meets normal atmospheric pressure, it becomes a gas again.
