Re: The Best, Least-Known Tips & Tricks

From the FAQ:

* Partial Recirculate Mode. The Leaf has a barely-documented feature that is actually very helpful in Winter, especially when combined with the next Trick after this. With the ventilation set to one of the modes that allows Recirculation (any of the non-defrost modes), and with Recirculate mode on, press and hold the Recirculate button until the light above it starts to flash, then quickly release it. The light will flash twice, then go out, making it look like the car is in Fresh Air mode. In fact, if done correctly (and it may take a little practice, to avoid re-engaging full Recirculate) the ventilation system is now taking in roughly 1/3 fresh air, and recirculating the other 2/3. This mode does two things: it reduces the amount of external smog getting sucked into the car, and it increases the efficiency of the heater in cold weather, because most of the air doesn't have to be heated from outside ambient. It is also called "Auto Recirculate" (not to be confused with Auto Climate Control).


If the valve does open and close automatically, what are the parameters that determine an open position? They are unlikely to be present only in Summer. Once I have more info I'll change it to reflect that.

On the Re circulation subject.
I noticed a marked improvement in the very cold. 0ºF. Below and a bit above. The Energy use meter would drop substantially when the "partial" was engaged. We have no way of knowing what parameters Nissan uses to operate this control in auto mode. May be there is a CAN buss output that LeafSpy could read. I know when I use Auto for heat or AC it starts in full recirculate mode then fades. I can tell this by the fan noise at the defrost outlets . I believe the car uses this vent as an intake during recirculation. That's why we cant have recirculation and defrost at the same time.
I will have to try it with AC in the summer to see if I get an energy reduction from using it. I tend to just use full auto in the summer anyway though if I am using AC. In Vermont AC days are not that often.

Recirculation happens if it's cold outside. Technical manual has logic drawing.
It is fixed at 30%. Partial recirculation is VERY good if it is cold outside and cabin is very warm.
With cold cabin it is absolutely useless. Still, if there are more than 2 people I switch to fresh
due to fogging on the rear windows.
