<p>A refrigerant circuit using a vapor compression cycle, the circuit usable for air conditioning, refrigeration or heat pump purposes. The circuit includes a lubricated compressor connected to an oil separator vessel separate from the compressor, a falling film or hybrid falling film evaporator and a condenser. The oil separator vessel extends substantially horizontally. The oil separator vessel is separated into a primary space and a secondary space by a filter pad configured to substantially remove entrained oil droplets of about 5 mum and larger from the refrigerant entering the oil separator vessel. The primary space is in fluid connection with a discharge of the compressor. The secondary space is in fluid connection with an inlet of the condenser. The circuit has an oil entrainment flow discharge of lubricant from the compressor of at least about two percent by mass relative to refrigerant flow.</p> |
