I am trying to understand this plumbing
scheme. Where in the circuit are the water pumps? Are they after the "Y
splitter", or on the line going from the core to the Meziere inlet?
They will be in the return line from the cores, to the
engine.
The pumps are likely to do better
at 'pushing' the liquid rather than pulling it, so you want the outlet of the
pump going into the evaporator core.
Actually, this is why I figured they'd be better in the
return line. It's also nice to keep the coolant pressure in the engine as
high as possible, so I figured it made sense to have the pumps feeding directly
to the engine.
One operational concern is if you are operating on
one core, and the thermostat calls for the second pump, when it turns on, it is
going to be delivering 'cold' fluid that has been stagnant in the core to the
engine. you 'might' end up with oscillations in the cycling of the pump. Will
this cause a problem?

Hmmm,
good question. I don't know if that will be a problem or not.
The one way valves require .5psi to flow, so even if the pump is off,
there might still be some flow. Unfortunately, I just don't have
a feel for how much flow, if any there will be.
BTW, I do
appreciate the comments. Fortunately, the difference between the
two plumbing schemes is a simple modification. I guess I'm just
trying to decide if there's any good that can come from running one pump
per core.
Cheers,
Rusty
