How does the aircon affects the fuel consumption?

[ronskiee]

Mga fellow tsikoteers, noob question lng po. Paano po ba naapektuhan ng aircon ang fuel consumption? Pag nilakasan po ba ang blower lalakas din ang gas consumption? Pag tinataasan po ba ang thermostat lalakas din ang gas consumption? Please enlighten me guys regarding this matter. Thanks in Advance peeps.

basically ithe thermostat activates the compressor. thr.compressor adds engine load. more load = more gas.

the comfort of AC outweighs the additional load imho

ibig sabihin sir, ung taas ng thermostat lvl at lakas ng blower ay hindi direktang nakakaapekto sa gas consumption? kumbaga inshort, basta umikot ang compressor lalakas sa gas, kahit naka low cool? tama po ba?

minimal effect lang naman. but yes, you get the point.

maraming salamat po, naliwanagan na po ako ngaun.. more power tsikoteers sa walang sawang pagtulong sa mga newbie na gaya ko.

you can actually feel the power drain when you turn on the aircon. you can feel the engine/car lurch just a little (suddenly slow down a little) if you aren't running fast... in some (older?) cars, you can read a drop of engine rpm..
the energy drain isn't too small.. up to 10% or so, some say... depending on the engine's size..
to compensate for this loss in engine power, there is the automatic idle-up circuit, and there's also your right foot..

Everything connected to the crank that is dragging its rotation consumes fuel.

More electrical loads/ Higher current draw = more resistance to alternator's rotational force.

Inclined roads, stop and go traffic, high-speed driving = more rotational force needed to move the flywheel.

Aircon compressor turned on = resistance in the pulleys. The lower the thermostat setting, the more and longer your compressor engages with the crank. The higher, does almost the same when your heater engages in a form of electrical load(heater coil).

sir pwede po pakiexplain pa ng husto? thanks
