* Petrol: The engine, which runs on petrol, powers the alternator. The alternator generates electricity that charges the battery.
* Battery: The AC compressor, which is responsible for cooling the air, is powered by electricity from the battery.
So, while petrol is the primary source of energy, it's the battery that directly powers the AC system.
Here's a breakdown:
1. Engine runs on petrol
2. Engine powers the alternator
3. Alternator generates electricity
4. Electricity charges the battery
5. Battery provides power to the AC compressor
6. AC compressor cools the air
Therefore, the AC system indirectly uses petrol to generate the electricity it needs, but it directly draws power from the battery.
