Today big heat! So obviously, I tried the air conditioning of the car. (this is my 1st car with air conditioning).
So, in urban driving, which is the case for most people, I realize that the compressor could only work when decelerating. From then on it would not cause any overconsumption! So I tried playing with the button and I managed to get the air conditioning, with the compressor running only at deceleration. Obviously, it is not practical, even dangerous, to take care of the green button instead of the road. But it seems to me that a small electronic assembly, coupling the compressor with the cut of the injection during decelerations should be beneficial

Hello
Relatively simple just cut the wire that goes on the (clutch)
clutch of the compressor pulley and pass it through a pressure switch and relay when the engine vacuum is high so engine brake for gasoline allows compressor coupling.
It makes sense if you go down a good rating, but in town the little deseccelaration not long enough to shoot anything!
normally in these systems it is necessary that the compressor runs one or two minutes sometimes more so that the effect of the freon is felt, on my air conditioning system in the house the first 5 minutes it is used only to warm the freon.
that gave me a problem when you install a unit too big for the necessary work, it leaves and stops too often. on 15 mintues of walking 5 minutes ago not profitable.
(Once you get used to air conditioning it's hard to do without it)

yes, it was already cold and I only had to maintain the cold, and I don't fix it hard anyway. On the other hand, the diesels not having depression, I would rather take on the accelerator pedal.
here in town we just accelerate and brake. we can't keep a constant speed. so the decelerations are not long, but we have plenty!
I'm going to see what I find as a switch, I don't see how it would cause a problem for the compressor, it already switches all the time. And I will put a button to choose the road / city operating mode, because on the highway it would never work.
Thank you André!

I have the solution: you have to dismantle the compressor, the radiator, the pipes ... and put everything in a box, on a shelf that's what i did on the bm, i gain in consumption and in weight
