Where does the refrigerant go?
Compressor - evaporator - condensor - receiver/drier - compressor?
(Do I have the receiver/drier in the right order?)
I ask because the receiver/drier connections are marked "in" and "out." I think I want "in" connected to the condensor and "out" to the compressor.
Why does it matter?

Hi!
You are corrct. Compressor to evaporator core(s) to the condensor to the reciever drier to the compressor. The reason it matter on which way the reciever drier faces is because if the desicant breaks down, you don't want it to flow into the compressor, right! In should face the condensor and out toward the compressor.
Good luck

NO!!
Compressor > condenser > receiver/dryer > evaporator > compressor
The reason that it matters is that the inlet tube stops high up in the can so that the liquid refrigerant from the condenser trickles down thru the filter and dryer to the outlet tube that is at the bottom of the can. This arrangement transforms the irregular trickle of condensed refrigerant to a steady flow with no entrained gas.

Hi Wally,
I am pretty sure that I have the orientation correct on the reciever drier. The "in" word faces the condensor for certain. The reason direction is critical is in fact to make certain that the filter doesn't allow debris to pass into the rest of the systems from the high side of the compressor. The debris from the compressor and the desicant can't be allowed to circulate around the coolant system otherwise it will cause the expansion valves to stick. The filter drier doesn' do that much to regulate or uniform the head of the coolant flow. Actually are more effective way to run this system is like they do in industrial compressors where many systems have a filter right after the compressor and a separate drier after the condensor.
With regards to freon transfer the correct movement is low side compressor-also known as suction side to high side of the compressor to top of condensor through and out the bottom of the condensor to the reciever drier then to the systems' expansion valves followed by evaporator cores and then the low pressure side of the expansion valves leading back to the low side of the compressor to complete the cycle.
If my earlier statement lead to alarms, I was not describing coolant flow, but the hose layouts.
We might be on the same page, but I just want to clarify
Sorry for any concerns

Hi Dozman,
I still think that "in" is attached to the condensor and out to the rest of the high pressure system. With regards to entrained gasees, I think that Wally may be referencing accumulator systems instead of reciever/drier systems. There is a difference. I know a little bit about a.c. systems, but show me if I am wrong here. I stand firm that the reciever/drier unit "in" labeling faces the condensor.
Check it again, maybe I missed something, but I don't think so.
Good luck!

fst -- It appears that Wally and you are on the same page about where the receiver/drier goes -- after the condenser -- and about where the refrigerant comes "in" from (the condenser) and where it goes out to (the rest of the system).
I think Wally was correcting where I had conceptually put the compressor (immediately before the evaporator, rather than immediately after). He's quite right, of course.
