Automotive Air Conditioning – Information

Automotive Air Conditioning – Information

One may think that automotive air conditioning is a simple topic and thus most car owners are shocked to learn at how complex the system and it’s subsequently maintenance can be. The basic principle of how ones car air conditioning works is simple enough for the layman to understand but the reality of having a functioning system calls on many systems to work in perfect harmony. As modern cars rely more on the marriage of electronics & mechanical systems to make them more efficient, so too does the complexity & scope of maintenance increase.

The basic mechanical components of the system are the compressor, condenser, receiver drier (or accumulator), expansion valve (or orifice tube), evaporator & hoses. The compressor is used to generate the desired high pressure of between 10 to 20 bar (that’s at least 10 times ones tire pressure!) in the high pressure side. This gives the desired low gas entropy needed to for the pressure drop and subsequent cooling that occurs through the expansion valve (or orifice tube) and evaporator. This process is all governed by the systems integrated electrical system which is made up of a combination of pressure switches, control valves, temperature sensors, thermostats & relays which are all controlled in real time via logic programmed into the ECU. Now the real challenge is presented to Coolco by each manufacture and their various models’ air conditioning systems having unique designs. Fortunately we have been a specialist in the industry long enough to have seen and conquered it all!

Below are a few posts to help inform one about the basics of how the air conditioning system works. Knowledge is power and we believe that one should always strive to have some understanding of the workings of ones most or second most valuable asset: the vehicle!
