fluid flowing therethrough application_number US 5050902 A description referring now to the drawings and more particularly to fig1 a dry suction ammonia refrigeration system is designated generally at 10 and a general flow diagram is schematically shown beginning at the control pressure receiver 12 liquid refrigerant preferably ammonia is pushed to evaporators designated generally at 14 the evaporators include processing units 14 a cooler units 14 b and a chiller 14 c obviously other types of uses are encompassed within the scope of this invention although not detailed in this drawing at each evaporator unit 14 a 14 b and 14 c the flow of liquid is completely evaporated to form a dry suction gas in order to distinguish between the forms of the refrigerant solid line 16 indicates refrigerant in a liquid form and dashed line 18 shows refrigerant in a dry suction gas form the dry suction gas is moved from the evaporators 14 to accumulator 20 where the gas is then drawn by a compressor 22 at the compressor the refrigerant gas is compressed and pumped to condenser 24 once condenser 24 transforms the gas back to a liquid it is returned to receiver 12 for another cycle referring now to fig2 the accumulator 20 of the present invention is shown in enlarged schematic form accumulator 20 is of a relatively radical design that is not used in standard systems suction gas coming back from the plant would enter via conduit 26 at a pressure of.
