REFRIGERATING PLANT Russian patent published in 2003 - IPC

FIELD: compression refrigerating machines. SUBSTANCE: the refrigerating plant has a circulating circuit comprising a compressor, condenser, heat exchanger-evaporator, regenerative heat exchanger, the first control valve, cylinder-type hydraulic cyclone and an evaporator, as well as the second control valve positioned in the line between the heat exchanger- evaporator and the hydraulic cyclone. The plant is provided with an air separation system including an ejector installed between the heat exchanger- evaporator and the regenerative heat exchanger and communicating with the condenser, as well as series-connected additional regenerative heat exchanger and an air separator installed in the by-pass line between the regenerative heat exchanger and the control valve. The air separator is made in the form of a cylindrical body provided with inlet and drain tangential pipe connections and separated by a partition, having a calibrated orifice, into two accumulating chambers. The upper accumulating chamber is provided with an outlet pipe connection with a valve connected to a float. EFFECT: enhanced reliability of operation and ecologic safety of the plant. 2 cl, 2 dwg
