Does a PF condenser have to be mounted with the entry/exit fittings horizontal? I'm adding an aux condenser w/fan in my fender. The one I ordered will only fit if the fittings are vertical. When I measured for the condenser, I didn't take into consideration the hose fittings.
It will work but it is not recommended. I personally think you lose a little performance when doing this. How much, that's open for debate as I have never tested it.
Parallel flow condensers depend on gravity for best performance. The idea is that already-condensed liquid refrigerant will drop to the bottom of the side header and flow through the bottom tube in each group. This keeps it out of the way of the condensation process in the other tubes.
Gravity is always best to work with, than to fight against; but sometimes we do. Given the higher pressure environment of a condenser, the gas to liquid phase change will occur from the adequate removal of heat, regardless of port orientation.
Thanks for the help. Installed the condenser with the inlet and outlet pointing down. That worked best with the hose layout.
I've got the system completely installed and it's blowing 40 degree air driving down the road (54 degree air setting still), that's COOL compared to no air at all!! I think there's more potential though.
I'm getting some crazy gauge readings. Low side 35 to 45, high side around 55 - 60.
I've installed a new Sanden 507 compressor, all new barrier hoses (approx 33'), a 12 x 14 condenser in the left rear fender w/fan, a 14 x 14 condenser in the left rear fender w/fan, a 9 x 27 condenser in the rear deck lid, new dryer, new expansion valve and new blower motor. Everything new except the evaporator, three speed blower switch and thermostat. Using HC 12a - Duracool coolant( approx 3.75- 6oz cans).
Anyone got any ideas for the wacky gauge readings? I'm taking the readings from the R-12 fittings located in the top of the compressor. I did not install gauge ports in the hoses, now I'm wishing I had.
Thanks for any help,
To save starting another thread, does this apply to serpentine condensers too? Can I fit it upside down?
As much as possible, condensers should always be plumbed so the gas from the compressor goes in at the top and liquid out at the bottom. A serpentine wouldn't care though if the direction of flow is reverse from originally intended (i.e. mount it upside down, and swap the lines to compensate) if that's what you're asking.
I was think more like having the line from the compressor at the bottom, and the liquid line at the top. Space is very tight and it saves using some very awkward pipe runs.
