    Fuel.

    Seeing as the battery is only storing electricity, the alternator is actually generating it. The alternator, like the air conditioning compressor, is driven by the crankshaft. The more load you place on the engine, the more fuel it uses. Even a load as small as the ventilation fan under the dashboard in the cabin still places an electrical load on the alternator, therefore it must make the alternator ever so slightly more difficult for the engine to turn.

    The answer has already been given it runs off electric and fuel.

    But here is an interesting fact, car manufacturers have known for YEARS a better way to cool cars and to keep them at a constant set temperature.

    And it actually uses the HEAT of the engine to do it. (which is why its not implemented on cold days you want the heat right away, not when the engine has warmed up) http://physicsworld.com/cws/article/news/2011/apr/...

    One day it will be in cars and not use precious fuel.

    It runs indirectly on car's fuel - operating the compressor draws engine power and increases fuel consumption accordingly, plus electricity from the alternator and/or battery to operate the controls and fans to force air into the cab.

    The blower motor that moves the air around the cabin is electric. The compressor the runs the refrigerant around the AC system is attached to the crank via pulley belt. So it's run by both fuel and electricity.

      air conditioning to cease. The battery can produce NO air conditioning.

    It's run via a pulley from the engine, and needs several horse power to operate. So it loads up the engine more, and so it burns more fuel. Even the electric parts like fans, that do operate via the battery also use engine power. The electrical power is also generated by the alternator which is engine driven.

    In a smaller car you can actually feel the power loss when the air con kicks in.

    Hi Most cars have a pump which run off the fan belt which means it only works when the engine is running. that drives the compressor pump which needs a fair amount of power taking as it does about 5-6 bhp of the engines power.

    Fuel. But it's worth every penny on a hot day.

  • the ac compressor is a belt driven pump. the ac clutch is really one of two parts that uses battery power. the other is the fan in he heater housing.
