An A/C system may be a complex setup but it also has to end somewhere. It indeed does, but only after it has brought down/up the temperature in your car's cabin. After that happens, the cycle repeats itself all over again. However, what you would be more interested to know is how the evaporator helps in bringing down/up the temperature inside your car.

If you have been following the workings of the A/C system with us, you would be able to recall that a refrigerant gas in first pressurized, then turned into a liquid its pressure is also brought down. But all you get to feel is cold air not water. This is the doing of the evaporator. An evaporator is a radiator-like device whose working is completely opposite of a heater. Here's how - the evaporator has piping in which the cold refrigerant liquid is circulated. The air in your car's cabin rises to find a place to get out of the car (since the car's cabin's temperature is more than th
at of the evaporator and hot gases always rise due to low-density). This hot air meets the refrigerant liquid via the piping in which it is circulated and cools down. Having become denser, it starts falling and the blower in your car throws it out at you. The refrigerant liquid traces its way back to the compressor.

But an evaporator can also give troubles to you. In such a case, it is important for you to know about the signs when the evaporator starts giving way and needs attention.

You like the fact that whenever you step into your car to go anywhere, in summer, you do not have to bother much about the heat outside. What has made your bothers go away Cars are still made of metal and except high-end cars, we still do not have the kind of innovations for our mass market offerings that can keep the heat from entering the car's cabin. Then how is it that you are still not bothered as much as you should be The reason for that is the Air Conditioning system that is present in your car. Over the years, it is among the top reasons as to why would you buy a car or anyone else suggests you to buy one. It runs on same basic principles as the Air Conditioning system kept at your homes, just that it is packaged in a tighter manner so that it can go along with the car to any place you want to head to.

Air Conditioning (AC) systems have been present on cars for quite some time now. So now, we do not just talk about ACs when we talk about cars, we talk about the next stage. This next stage is called Automatic Climate Control AC (we would refer to it as Climatronic AC for the sake of shortening it for further use in the article). Early AC systems were the kind that would keep cooling/warming the cabin irrespective of how the users felt about the same. They were turn on/turn off switches than anything else. Today's Climatronic ACs are the kind which are more than just turn on/turn off switches. All they ask you to do is set the temperature and they handle the fan speed and the amount of cooling/heating that you have asked for. This is the reason why such systems have started appearing on mass market cars. Such systems have become more of a necessity than just a luxury item.

Among the components that are present in an A/C system of a car is the condenser. Its turn to work comes right after the compressor has finished its work. If you go back to our article about the compressor, you would know that its purpose is to pressurize the refrigerant that cools the air down. But before the refrigerant can cool the air down, it has to lose the temperature it has gained by pressurization. This is where the condenser comes into play.

The condenser is mounted in front of the radiator in the engine bay of a car (usually). Due to its mounting position and its appearance, it is also called mini-radiator. The refrigerant gas is made to pass through the condenser where cold air brings its temperature down, cooling down the refrigerant gas and changing its gaseous state into liquid. This liquid then moves on to the dryer.

While it sounds simple, the process is a lot more complex than that. This also makes the condenser an item of great importance. Any fault in the condenser, therefore, can lead to bigger problems than just making your car's A/C system malfunction.

A car's Air Conditioning (A/C) system is a complex setup. Unlike how people think it functions, how it really does what it does is a wonder in itself. Working near the engine makes the A/C system's access to cold air a near impossible scenario. Still, you get to bask in the cold air it throws on hot days. Have you ever wondered how If you have, today is your lucky day to get to know an important component of the A/C system in your car. If not, by the time you finish this article, you would be raring to know more.

To generate cold air out of hot air (an abundant item in the engine bay), an A/C system needs a lot of components. However, the most basic component it needs, which actually begins the process, is the compressor. As the name indicates, its purpose is to compress. But what does it compress, you may ask. It pressurizes (compression is a form of pressurization) the refrigerant, which, in turn, cools down the incoming air. It is also present to sense temperature changes which you control via various buttons inside your car's cabin. It is powered by a belt and since the system is mechanical, which also explains why turning the A/C on also brings the fuel economy of your car down.

An A/C system deals with liquids and gases and their temperature modulation to provide you with cold air in summer and hot air in winter season. But it is not just a complex system, it is also a very sensitive system. There is a reason why A/C system on a car is a sealed unit. It is sensitive to moisture and humidity. If moisture enters the system and reaches the compressor, it can mix with the refrigerant liquid and cause corrosion to spread throughout the A/C system.

However, the A/C system has a safeguard from moisture and humidity in the form of an accumulator/receiver-drier. An accumulator/receiver-drier is a component that draws out the moisture from the system and blocks it from reaching the compressor for which it also has a desiccant (the small pouch you see when you open a box of Orbit or any electronic gadget that should not be exposed to moisture). This component also traps pollutants inside the A/C system through a filter. Lastly, this component also stores oil and refrigerant till further use.

There are a few differences between accumulator and receiver-drier. The first is that an accumulator comes with an orifice tube whereas the receiver-drier has an expansion valve accompanying it. An accumulator is also bigger than a receiver-drier in size and hence, volume too. An accumulator is placed in the low-pressure section of an A/C system while the receiver-drier is placed in a high-pressure section. Unlike a receiver-drier which holds refrigerant temporarily, an accumulator's primary purpose is to store the liquid refrigerant coming out of the evaporator and preventing it from entering the compressor.
