classicretrofit Posted April 26, 2020 Posted April 26, 2020 People ask us whether they can use the "Kool N Duct" vent in their Electrocooler systems. This is not possible, because of the way we use the footwell ducts. In the original Porsche design, the duct is split into two halves - there is a divider in the centre. The part nearest the front of the car is for cold air and the nearest the driver is for hot air. The two come out and get mixed in the footwell. In our design, we use the hot side of the duct to pull air out of the cabin. The cold side is used to push AC cold out. You have to split the cold away from the inlet otherwise the cold air will just be sucked up into the inlet and not reach the driver. The reason we did this is to achieve recirculation without having to cut the bodyshell. In our manual we show the simple 'snorkel' modification starting on page 26. One of our customers, Stefan (PP username austria3) has come up with a tidy solution and has made 3d print files available. They are now on our downloads and manuals page. Thanks Stefan! Here is his solution, see how the cold air is kept separate from the inlet?
