You could have pondered (while stuck around the M60) that this air conditioning really works, otherwise you have never given it a moment's thought. Just in case you are curious, let's explain it to you personally.
Air conditioning want it says 'conditions' the environment. It not merely cools it down, but in addition reduces the moisture content, or humidity. All air conditioning equipment can work exactly the same way whether they are placed in a building, or perhaps a car. The fridge or freezer is at a way an air conditioner too. Air conditioning is usually a field in it's own right, but we'll continue with the main points or an auto's air cooling and the main parts used and many hints to keep the oxygen-con system running properly.
A amount of people don't realise that turning for the air conditioning actually cuts down on the number of miles per gallon of one's car. There is energy employed in removing the moisture and heat from air in the car, this also consumes petrol due to the extra engine load.
Air conditioning's main principles are Evaporation and Condensation, then Compression and Expansion. To the engineer and physicists they talk of thermodynamics - but we'll explain it inside our own way here:
Evaporation: You may have seen that if you rub a bit surgical spirits within the back of your respective hand, after that your hand will feel cold. Why is that? It's evaporation. It is because the spirits around the back within your hand begin to evaporate. As the spirit evaporates, you will need away heat through the surface of one's skin.
Heat of Compression: Have you ever noticed after you pump up a bicycle tyre using a hand pump, that this end from the pump gets hot? This is because the force that you have put into the environment by pumping it has not simply compressed it, but also has caused air molecules to push closer together so giving out heat while using friction.
Compression: At some point all gases may ultimately become liquid. An example of that might be a can of deodorant - it's liquid within the can (since you can hear it after you shake it) but is often a gas when considering out and hits your underarm. The pressure within the can is higher, hence the propellant inside is liquid.
Anyway, enough about takeaways, armpits and surgical spirits, but those are definitely the basic ideas which can be easy enough to spell out. The important real question is how does all of this fit into making the car's vents blow cold?
The fluid that passes throughout the whole strategy is the refrigerant. The refrigerant can evaporate at the low temperature, then condense again for a higher pressure. In the bad days of the past, R-12 was the refrigerant found in almost all cars. It was acquireable, but it surely was found to become contributor to the outlet in the earth's ozone layer since it was a chlorofluorocarbon (CFC). These refrigerants were discontinued, and all sorts of cars after 1996 make use of a non-CFC fluid called R-134A and that is kinder on the environment.
So, this is one way all the various parts of a vehicle's ac works:
Compressor: The compressor would be the work horse of the air-con system, powered by the drive belt connected towards the crankshaft with the engine. When the aircon product is turned on, the compressor pumps refrigerant vapour under high pressure for the condenser.
Condenser: The condenser is often a device familiar with change the high-pressure refrigerant vapor with a liquid. It is mounted in front with the engine's radiator, and it also looks very similar to some radiator. The vapour is condensed to some liquid with the high pressure that is certainly driving it in, and this also generates a lot of heat. The heat is in turn removed from your condenser by air flowing with the condenser around the outside.
Receiver: The now liquid refrigerant moves on the receiver-dryer. This is really a small reservoir vessel for that liquid refrigerant, and removes any moisture which could have leaked to the refrigerant. Moisture inside system causes havoc, with ice crystals causing blockages and mechanical damage.
Expansion Valve: The pressurised refrigerant flows in the receiver-drier to your expansion valve. The valve removes pressure in the liquid refrigerant then it can expand and be refrigerant vapour inside the evaporator.
Evaporator: The evaporator is an additional device that appears similar to an automobile radiator. It has tubes and fins which is usually mounted in the passenger compartment behind the fascia across the footwell. As the cold low-pressure refrigerant is passed to the evaporator, it vaporises and absorbs heat from the oxygen in the passenger compartment. The blower fan in the passenger compartment pushes air within the outside with the evaporator, so cold air is circulated inside car. On the 'air-side' in the evaporator, the moisture in the environment is reduced, and also the 'condensate' is collected and drained away.
Compressor: The compressor then draws inside low-pressure refrigerant vapour to begin another refrigeration cycle. The refrigeration cycle then runs continuously, and is also regulated with the setting on the expansion valve.
The whole process in all fairness simple when explained prefer that. All ac systems work for the same principle, even when the exact components used are different slightly between car makers.
We hope that explains slightly as to how that little 'A/C' button conditions your car, should you want it explained a bit more complete then in case you roll up your sleeves we can easily show you the parts in the car next time you carry it in for a cheque or service right here at AirconCars.
