COOLER UNIT AND PROCEDURE FOR CIRCULATION OF COOLING FLUID MEDIUM IN IT Russian patent published in 2011 - IPC F25B1/53 

FIELD: machine building.

SUBSTANCE: cooler unit consists of main compressor (190), of condenser (140) positioned downstream after main compressor (190) and communicated with it by fluid medium, of main expanding device (170) located downstream after condenser (140) and of evaporator (180) located downstream after main expanding device (170) and communicated with it by fluid medium. The cooler unit also consists of turbo-compressor unit (160) by fluid medium communicated with evaporator (180) and main compressor (190) and at least of one heat exchanger (150, 152) with hot branch (150c) by means of supplying line (145) connected upstream with condenser (140), while downstream - with main expanding device (170) by means of bypass line (149). The heat exchanger also has cold line (150f) connected upstream with expanding device (142, 144) arranged on branch (146) of line (145), while downstream - with turbine section (162) of turbo-compressor unit (160). Output of turbine section (162) is located downstream after evaporator (180). Invention also refers to the procedure for circulation of cooling fluid medium inside the above said unit.

EFFECT: raised efficiency of unit.
