<p>The present invention relates to a refrigerating plant that includes a compressor (2), a condenser (4), a phase separator (1, 101), an evaporator (17), connected in series with conduits (3, 5, 16 and 18 respectively) to form a closed refrigerant loop, and further comprising a high-pressure conduit (21, 21a, 21b) that connects a high-pressure outlet (21, 120) of the phase separator (1, 101) with the compressor (2). The phase separator (1, 101) has the form of a machine in which incoming refrigerant is subjected to pressure reduction and separation into an essentially gas-containing gas phase and an essentially liquid-containing liquid phase, wherein the liquid phase is discharged through a low-pressure outlet port (15, 115) whereas the gas phase is compressed and discharged through the high-pressure outlet (20, 120) of the phase separator. The invention also relates to a method of enhancing the refrigerating capacity of the refrigerating system wherein refrigerant entering the phase separator (1, 101) is subjected to pressure reduction and separation into an essentially gas containing gas phase and an essentially liquid-containing liquid phase. The liquid phase is discharged through a low-pressure outlet port (15, 115) and the gas phase is compressed and thereafter discharged to the closed loop.</p> |
