Can you split the discharge line to 2 cond?

kamoo on Sun August 29, 2010 2:17 AM User is offline

Im putting an a/c in an older school bus, and for ease of installation was going to run a single TM31 and dual 32k BTU evaps. Rather than run into a single condenser and split after into the two evaps, is it feasible to run #8 on the discharge and split before the condenser into two #6 lines into seperate condensers and rejoin on the suction from 2 #10 int a single #12? I guess my question is, can you split before the condenser?

I do not know exactly why, I would theorize it has to do with maintaining equal pressure on the dual orifices; but every dual evap system I have ever seen will use a single condenser or condensers in series and split to the evaps after that point.

Is this the same vehicle as in this thread?

Kamoo's other thread

Given the cost of a TM31, it would be cheaper to mount two SD709's...

The other 'ice' may pitch in here and offer his advice...but from the description of the system....seems like a lot of places for lubricant to 'puddle' and of course, this will result in serious system failures.
Why not follow the advice give in the original post....two compressors...two evaps...two condensers....yep...two systems....can almost guarantee that this system will perform much better.
Chrysler used a two condenser set up on some of their vehicles...a primary and a secondary sub cooling unit. If your heart is set on this type system....consider this. A much more feasible system and should reduce the possibility of lubricant starvation.
Best bet is two separate systems.
