OIL IN REFRIGERATION SYSTEMS - RSES.org
www.rses.orgOIL IN REFRIGERATION SYSTEMS Of the refrigerants that undergo phase separation during operation, only R-13 and R-22 have caused problems. These problems can be avoided through proper design. Several important factors help to keep oil from accumulating in the evaporator, which causes "oil logging." The factors include the following:

Proper design and arrangement of accumulator vessel(s) and defrost condensate return piping will result in continuous removal and isolation of water-laden ammonia from the system and is described in this Handbook.
