  Your assumption is correct Also your car automatically calculates the condensation point and keeps the temperature and air moisture low enough not to cause any fogging on your windshield. Source: I’ve been programming AC unit controls for cars for the last 10 years

    How upset do you get when your buddy disables auto and proceeds to slam back and forth between full heat and full ac while claiming their shitty dial dj set is somehow waaaaay better than the computer?

      That’s an instant un-friending offence

    They only do this with the automatic controls not basic knobs right? Apparently affected what filter I had to get.

      Yes of course. The old school manual controls are usually mechanically connected directly to the flaps, so you cannot have any automated handling there

        Thanks, just didn’t know how far we strayed, my first car had separate keys, apparently the new one can detect air quality and automatically close, new is also relative.

    thank you for your service

  in a lot of newer cars they can actually use the A/C to heat and cool the car, rather than using excess engine heat or an electric heater which is especially helpful when it’s cold and you’ve only just started the engine!

    Fun fact (well, I suspect you know this already, but some didn’t, I had discussion with someone arguing with me that this is not true):

    AC and a heat pump are basically the same thing, AC is just pumping the heat outside instead of inside.

    Also when you say modern cars I am assuming you might be talking about EVs. Using a heat pump requires less energy than using resistive heating so it could be energy saving measure.

    ICE cars on the other hand can get the heat from engine “for free” (not really, but since the heat will be produced anyway whether you use it or not, so why not use it?) so a heat pump might make a bit less sense in them.

      You still need a heat pump for cooling in ICE cars

        True, I mean just for heating using engine is cheaper.

    I assume you mean EVs with heat pumps? I don’t know of any ICE vehicles that do this, seems inefficient to waste mechanical or electrical energy when you have perfectly good waste heat to use upon reaching operating temperature (though you may need to use an aux heater before reaching that, particularly on diesels)

    • Natanael@infosec.pub ⁨2⁩ ⁨weeks⁩ ago

      Lots of new EVs have heat pumps, in cold climates they need it because the car doesn’t generate enough heat just from running.

      It’s also an emergency safety heat bleed if your engine is overheating, redirecting some of the heat from that engine block can save your radiator some trouble and keep it going a few more miles

    My car is a diesel so it takes a long time to warm up in the winter. They added an electric auxiliary heater to compensate. The air is really hot within seconds.

    My car is an EV, so it definitely does this because there’s no excessive engine heat to use.

  Yall have a defrost button?
