Abstract An ammonia refrigeration system capable of cyclically utilizing lubricant oil is comprised of compressor, condenser, oil-storing device, liquor-storing device, intermediate cooling device, low-pressure circulating barrel (or ammonia liquor separator), oil-cleaning device, oil-collecting device, liquor-discharging barrel, ammonia pump, evaporator and other various control and indication elements, which are connected together by means of pipeline. It is characterized by that a pressurized type oil-collecting device is mounted between low-pressure circulating barrel (ammonia liquor separator) and liquor-discharging barrel, a heat-exchanger is mounted in the interior of liquor-discharging barrle, and the oil-cleaning device is mounted after compressor.
