skan855,
I am confused, which type of system are you designing

1/ Liquid recirculation with liquid pump
2/ AKVA type expansion valve with accumulator(slop pot, suction trap) in plant room with boil of coil in it (serpentine coil, high pressure liquid line to evaporators running inside suction accumulator in a separate coil
to boil off any refrigerant that returns from evaporator for any reason to protect compressor).
3/ gravity feed surge drum mounted over the top of evaporator/s using thermosyphon principle.

1/ most expensive liquid recirculation
3/ less expensive used with 1-6 separate evaporators approximately
2/ cheapest

You mention long lead time of 6 weeks for AKVA valves, what is lead time on the rest of the equipment?
