I`m only surprised it was an older lady. Normally the one who gives me any Gip will turn out the be under age to even drive!
Yes?. That is what they are for?. I always turn the damn annoying "Stop Start" off too. there is a way to permanently do it, but as it`a SWMBO`s car she wont let me!.
I suspect the title "Natural Recources Canada", Has a prejudicial bias on that too?.
I try and avoid using the AC to clear the screen, the water is quickly condensed on the coldest point (the AC evaporator in the dash) when you switch the engine off the coldest point is then usually the windscreen, and the moisture migrates to it making the problem worse when you get back in the car.
But that is exactly what air con does...in winter have air con on with heat... produces warm DRY air.I try and avoid using the AC to clear the screen, the water is quickly condensed on the coldest point (the AC evaporator in the dash) when you switch the engine off the coldest point is then usually the windscreen, and the moisture migrates to it making the problem worse when you get back in the car.
It's best to use the heater to thoroughly warm everything up, evaporate all the water and get it out of the car totally.
So to achieve the same speed it will need a greater quantity of fuel and air mixture to make the target?
It doesn't evict all of it. The evaporating temperature of an AC is usually about 0°c, so if the system runs continuously the evap won't ice up, the water condenses onto the evap out of the atmosphere and if there is enough of it, it will drain out of the car underneath. By the time the drain starts dripping there will be plenty of water left on the evaporator and in the evaporator drain pan to cause condensation problems in the car when you stop the engine and park up.
Where do you think the moisture goes out of the air?
it'll be back 
This is in relation to larger vehicles like our motorhomes, right?
This is exactly why really low speed limits don't work. The lower the speed limit the safer the driver feels and the less attention they pay to driving. Imagine if the speed limit was 0.001MPH the driver might be inclined to have a kip
I thought we were talking about engine efficiency which doesn't change because of reduced oxygen levels. The engine compensates by reducing fuel supply, the driver demands more power to continue at the same speed, the engine supplies more fuel and draws in more oxygen and we're back to where we were. No change in efficiency or fuel consumption.
No.
No we have a VW UP with AC. I really try not to use the AC in winter, but I have to a couple of times a year when the screen inside is fogged and I need to drive it away. The AC quickly clears the screen. But there is a price to pay if you don't switch it off and get the whole car warmed up to expel the water before you next use it, if not when you next use the car the screen is fogged up again and maybe you think 'wow isn't AC great as it clears the screen' ... Actually it's caused it
Oh Richard and Ann ... yet again you advising when you don't know what you talking about..Where do you think the moisture goes out of the air?
It condenses on the evaporator embedded in the dash inside the car... It doesn't go very far I'm afraid
Don't think so..No we have a VW UP with AC. I really try not to use the AC in winter, but I have to a couple of times a year when the screen inside is fogged and I need to drive it away.

This is 100% Tosh, the water drains out under the car.No we have a VW UP with AC.

I bet you wouldn't turn down a 3% pay rise.
Oh dear. When you've been a refrigeration engineer for 25 years including CWS supermarket, RGR refrigeration, York refrigeration, Consort Refrigeration, Foster Coldstores, and self employed for 10 years maybe I'll start listening to you
The condenser is so called because it condenses the high pressure refrigerant VAPOUR back into it's liquid form. It's not called a condenser because the condensation forms on it and then drips out of the fridge or AC ... That's called the evaporator. The refrigerant boils at say 0°c inside an AC evaporator, Or -35°c in a freezer. Next question please
Absolutely right, it drains out, but the evaporator remains wet. And so does the drain pan under it.

The Evaporator. Final answer.
the stuff the military do is so different to commercial refrigeration he was completely useless, ringing me up constantly, nice lad though he got there in the end no offence
Oki doki. Why is is on my driveway and not my carpets
Because it gets collected by the evaporator drain pan inside your dashboard and then drips out under your car onto your driveway.
