If the quantity of refrigerant in one independent/separate refrigeration or air-conditioning system, is such that it would create a concentration in air above 20% of the LFL and the refrigerant has a "yes" beside it in the control measures column in the table... 6/06/2008 · The term g/l separator generally applies to most refrigeration accumultors which do not use demister pads or impingment vanes. A typical accumulator is depending on velocity reduction, change of direction, vertical separation distance and gravity for proper separation of the liquid and vapor. Other separators depend on a mesh pad, vanes or centrifugal force to start coalescing of te droplets

Refrigerant migration: Refrigerant migration is a term used to describe the accumulation of liquid refrigerant in the compressor during periods when the compressor is not operating. It can occur whenever the compressor becomes colder than the evaporator, since a pressure differential then exists to force refrigerant flow to the colder area.... Page 2 Guide to good leak testing Commercial and industrial refrigeration and air conditioning systems leak too much refrigerant – leaks of up to 30% of the charge during a year are not uncommon.
