Re: refrigerant velocity in evaporator
Hi Peter,
There is adifferent angle to the oil problem. For proper oil seperation there should be sufficient discharge super heat.Ex in case of R22 more than 25 deg F.Say your compressor runs with liquid flood back or sucking wet vapour you normally end up with oil problems

Re: refrigerant velocity in evaporator
Seems to me that it would work much better if the flow were reversed. Each path would be downhill all the way, instead of uphill. Velocity is only important where refrigerant vapor is trying to push oil uphill.
