proper oil return. freon and oil migrates to the coldest area/evap coil. need a high velocity for it to get sucked back to the compressor. if we put a trap at the outlet of the coil and slope it to the trap then oil fills the bottom of the trap and the compressor can get a good slug of it and suck it back.
