Understanding Your Car’s AC System
Most cars have AC in order to make summer driving more enjoyable. In the South, it’s almost required to have a good air conditioner, and when it quits, everyone suffers. Getting stuck in rush hour traffic is bad enough with AC!
In order to conserve fuel, turning on the AC is a no-no, but it’s it’s hot, you may have to. If the car overheats, dangerous things can happen, but if the driver is overheated, road rage can happen. The AC requires almost 8 horsepower to run. This consumes fuel. However, when on the open road where the speed limit is sixty, running the air conditioner is probably a better financial choice than having the windows open. If the window is down it will create a drag and make the car work harder.
How does the air conditioner of the car work?
Your air conditioner for your automobile works in the same way your window A/C works. Freon is a gas that is contained by being sealed. Then, a compressor pressurizes the Freon. As this happens the heat around the unit is absorbed. Then the hot gas that is absorbed is passed over a series of coils or tubes that disperse the collected heat. The system doesn’t let out cool air, but it takes away heat. The gas gets extremely cold and turns into a liquid when pressure is reduced. The newer models of vehicles use an environmentally friendly Freon R-134a instead of the original Freon that was dangerous to work on and hard on the Ozone layer. It’s not illegal to work on these without a license.
There are several components to the operation of the coolant system.
A compressor Is the major part of your system. The compressor does just what it says and compresses the Freon used to create cooling. The compressor is connected to the engine by a belt. Within the compressor is a clutch which is engaged when you turn the A/C in your vehicle on or up.
Located next to the radiator, there is a condenser. Cool air is pushed in the car by the radiator. In order to control it from getting too cold, there is a thermal expansion valve. This is how you will choose the temperature. There is also an accumulator to filter and collect sludge.
