***** type DX evaporator instead Ammonia type

[A.Mortezania]

Dear Friends,

As you know at ***** type DX evaporator for cold rooms, we connect suction line to bottom of suction collector to carry oil better to compressor.
As you know oil bringing back to compressor at ammonia system is different, still outlet pipe of evaporator (to separator) connects to bottom of evaporator or it obeys other rules ?

Sincerely yours.

Same rules with "p" or "s" trap on unit same as ***** or synthetic refrigerants.
It will probably return in small slug though as not miscible with ammonia.
Ammonia not very good on low temperature application with TX valve though.
