TEV for 3-banger chiller?
We have been griping about the inability to apply an expansion valve in the CPU, VC, and chipset cooling applications. But in considering Bowman 1964's 3-evap single system design, I decided that if we attribute a 150w load for each evaporator (450btuh approx.), times 3 evaps = 450w (1,350 btuh) or .1125 tons.....
Guess what.... that's right in the ballpark for a Sporlan EF-1/8 expansion valve.
:D

You could try mounting a low pressure reciever/suction accumalator on the outlet of the evapourators with a common suction which you control the superheat on?

I've seen a few folks try to run 2 or three evaps in parallel from one TXV with limited success. The problem is the ability to feed the coils correctly under all conditions. Unless you have some sort of distributir, the feed will be very problematic at best.
